Re: [Emc-developers] Withdraw Pi support?
I would leave it in and include a large warning that this installation is experimental/unsupported due to varying reliability issues. I would also include links or suggestions on how to find the history on RPI implementations and issues. I think the RPI is a powerful solution and it will only get better. Having more access to the installation (even if it has issues) will encourage experimentation and make it easy for someone to establish a baseline system so they can fix the underlying issues. I've been using the RPI 4 as a VPN endpoint for remote access and it has been very reliable. There are so many RPIs out there now, that if a specific version is required to make it work, it should not be difficult to find that version.

Re: [Emc-developers] probably an un-answerable question
I'd consider using a used propane tank from a torch. One of the throwaway steel tanks. You want to make sure you purge it of propane, but after doing that you should be able to solder brass fittings onto it. Those are good for a couple hundred PSI.

Re: [Emc-developers] Ethercat driver
Why a license? I have no idea. It sounds like they want you to ask permission. However I am quite sure the software will work without permission being granted. So what's the point? And if you obtained a license, what exactly do you do with it? Print it out and paste it on the wall? Put in in your wallet next to your fishing and driving license? Was "Ethernet" ever licensed? I was around when DEC first started selling Ethernet systems. Back then there was a lot of mystery (and cost) around setting up an Ethernet system. I remember a tap kit for semi-rigid Ethernet cable costing thousands of dollars. I still have some of that "cable" around here someplace.

Re: [Emc-developers] INI edit from inside gui
I put together a computer specifically for a Flow Waterjet running the Flow software late last year.

I ended up buying an older, new motherboard that was available on Amazon. Besides the cost of the OS, there are some other good reasons to move away from Windows.

Re: [Emc-developers] [Emc-users] Tool offset
To do tool comp requires a lead in move. I've always turned on/off the digital I/O via M64/65, paused to allow the action to take place, and then turned on tool comp and made the lead in move. But that was for a waterjet application where the jet has to penetrate the material before starting the cutting motion. I think I did that because there was an issue with M62/63, but I don't remember what the problem was. It may have been that M62/63 didn't like having a pause after the M62/63 statement. If he is dropping a knife, he may need to pause for a short period to allow the knife to drop fully before making the next move. For waterjet programs I turn tool comp on and off for each cut since you need to tell the system which side of the cut you are going to apply tool comp to. The Gcode is all cam generated so once things are setup, it just works. Andy, does it look like it would be an easy fix to allow M64/65's when tool comp is on ?I've never understood why that interlock was put in place.

Re: [Emc-developers] Gremlin parsing code with infinite loops
You can get around that by not doing infinite loops! ;-) Seriously, if you have something like Classic Ladder initiate the program you can run as many parts as you want and still have the Gcode terminate. That avoid the infinite loop issue. The needed bits to trigger and monitor the program are all in Hal. I have a machine that has a PYVCP panel that is tied to Classic Ladder. You enter the number of parts you want to run and push the go button, the the machine indexes sheets into the machine, cuts them, and indexes the cut sheet out the other side. The operator loads sheets onto a conveyor which feeds the machine.

The software for the S7-1200 is structured so it can easily handle and organize thousands of I/O while maintaining sanity. If that is too much $$ I would look at the Automation Direct Click PLCs as they now have an ethernet module. But the programming software is not nearly as good. Regarding price per point, I doubt that anyone can beat the Click PLC. If they are not big into ladder logic, the Siemens controller also supports SCL which is similar to Pascal and has familiar if-then-else programming features.

Re: [Emc-developers] Spotted on Ali-Express (Via the forum)
At one time or another I have read through all of the GPL license verbiage.If you do that, you need to have some coffee on hand, otherwise it is nap time! I buy and install a lot of Siemens automation hardware. Every HMI/Operator screen that I buy comes with a small CD that has nothing on it other than GPL'ed source code. They make extensive use of GPL software in their HMI industrial products and they have a shipload of lawyers to tell them what they can and can't do and still be legal in basically every country on the planet. I've read the GPL licenses and from what I have seen, if you follow the rules and simply make whatever software you add to a GPL'ed project also GPL, you can sell the hardware with the binary software preloaded. That is exactly what Siemens does.Their HMI screens cost from about $300 to $3000 each typically. Their hardware has the current technology which is near impossible to reverse engineer for most mortals, so giving out the source code is like giving a person the key to your safety deposit box but not telling them which bank or country the box is located in. More and more of the equipment I buy has some level of GPL software content. You open the box and a little CD falls out. A sure sign of installed GPL software. Regarding Tormach, it appears that they have taken the same approach. The last I heard, you can get the source code to everything that they supply. So basically Tormach followed the same rules and they sell machines and make a profit and benefit from using GPL'ed software.Most people know that Tormach was not the first nor will they be the last. Smithy was doing something similar but IMO they weren't following the GPL rules. When I tried to get their source code years ago they just gave me the run around. Letters and phone calls got me no where. Regarding the guy selling the product from China, if he supplies a CD with the source code, including his driver code (not that I know that he does or not) how could he be violating the GPL ??

I don't know if they actually state that or not. Besides, doesn't all licensing and licensing legalities stop at the China border?I'm pretty sure that Mach3 is freely exchanged in China.

It doesn't seem like dealing with burst output quad encoders would be difficult to handle. I think the PIDs could be disabled until after the positions were established by the encoders??

Re: [Emc-developers] Shielded connectors (XLR audio plugs)
I recently put together a stepper control box and used XLR connectors and made up 5 cable sets for the motors and they worked very well. There are some high quality XLR sockets and plugs available for very reasonable prices. Much nicer than the round connectors oftentimes used on Chinese machines. Look for Pro Audio supply houses.

Re: [Emc-developers] Shielded connectors (XLR audio plugs)
I could not remember the brand, but it was Neutrik. I used the metal ones and they really worked well. These are the exact parts I used. http://www.markertek.com/product/nc4fx/neutrik-nc4fx-4-pin-xlr-female-cable-connector http://www.markertek.com/product/nc4mp/neutrik-nc4mp-male-4-pin-chassis-mount-xlr The picture of the plug is not correct. The color was silver and there is a button that you depress to release the lock. These plugs will not fall out and they click nicely when inserted. These guys also have free shipping and they shipped them out quickly. It was money well spent as the box I did was setup to run both a little lathe and a little mill with the same control box and this made it easy to change the motor connections. And yes, they have been warned not to pull the plugs with the power on!A big warning sticker was placed next to the jacks. That should extend the time until the drives are blown! :-) Dave On 10/13/2015 5:09 PM, Kenneth Lerman wrote: > I'm using the plastic version of the Neutrik connectors for my servo power > leads.

Re: [Emc-developers] step losing
I think the fundamental misunderstanding here is the internal counting which is far more accurate and does not have the accumulated error that was assumed. Any step error seen (+-1) is where this number is digitised and the machine moves to the nearest step. You may think that going to a high microstep will give you this accuracy but please do not fall into this common trap, you need the resolution mechanically and as mentioned it needs to be far better than the accuracy you want to achieve. http://www.micromo.com/microstepping-myths-and-realities Dave Caroline -- ___ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers

Re: [Emc-developers] Problems building in place on debian wheezy
Seb means that the software joints_axes does not allow a configuration for a lathe to operate, since lathes typically have two axes X and Z, but no Y axis. There are lathe configurations (ini and hal files) in the examples. You would have to go back to the joints_axes version and figure out why that is occurring and then fix that.

Re: [Emc-developers] putting some mods to gs2_vfd.c into mainline
To bring a vfd to stationary fastest the vfd has to have control to use the deceleration curve/braking resistors if fitted and used. Therefore keeping the vfd powered is safer in the initial stop, only then should it be powered down.

I reviewed your patch and gave you feedback on what you would need to fix for it to be mergable. You never finished it. https://sourceforge.net/p/emc/feature-requests/125/ Sounds like we need a couple of FAQ items to communicate what is expected for patches. I will say that reading the feature request log that both parties were clear: 1) it needs a little cleaning up and documenting in order to merge into the source. 2) the poster is not familiar with what is meant by the terms white space, and was unsure about how to edit the documentation. In all of this there are two assumptions that should be clearly expressed. 1) most of the developer/maintainers either do not have the time or choose not to spend time to clean up code formatting and style issues. It might seem trivial for one or two additions, but could easily turn into a full time job, and we really need people to make their new code look as close to code around it. This will help its long term maintainability, and we have to rely on the posting fixes/additions to sort as much of this out as possible. 2) The original poster figured that he got it close enough and wanted us to jump in and polish it up. What he should have done at that point is either get on IRC or email the list and ask for help instead of assuming that someone would read the feature request and jump in. So, you basically need to find either a champion or a fellow compatriot to help do the finish polish. It might take awhile to find someone to help -- as most of us are insanely busy, and unless this is something that we *NEED*, we end up working on our own projects. There are probably a couple of dozen little features which are in the same state. I know that I submitted a *huge* patch to fix a 32/64-bit issue awhile back, and I doubt that it ever got pulled in as there was something that needed changing and I had a huge job at work come up, and only the gods know whatever happened with it... Now that these things are being tracked better, it is less likely to be dropped and forgotten. That said, I think giving a couple of these hung patches to a GSoC intern would be a great help.

Re: [Emc-developers] Tool Table and Wear offset Table
I am working on a Linuxcnc retrofit on a 2 axis waterjet. They use abrasive along with the waterjet to cut steel and aluminum on this machine. If they are cutting out a large sheet of material, the nozzle will wear and the jet will become a larger diameter during the course of the job. They would like to be able to adjust the jet size (think tool diameter) on the fly or at least do it as the machine is paused, or stopped, and then do a run from line to resume. The tool table seems to be in a state of flux right now so I am looking for advice on how to best do this. In the message string below (lathe application) the G43 and G43.2 is discussed in the context of a lathe. Would the same work for tool diameter? With a G41/G42 and a G41.1 and G42.1? It looks like G41.1 and G42.2 deal with the tool diameter directly whereas G43.2 incrementally adjusts an existing tool? Does it matter which tool table I use to do any of this? I have 2.6.3 installed right now on the machine but I have the 2.7___ master LinuxCNC master installed on a different PC so I can test with either software. Any advice is appreciated.

Any thoughts, Thanks I am using axis, too lazy to switch, and I don't generally fix whats not broken. But I am seeing something similar, not in the backplot, but in the axis code display window at the bottom. Anytime a tool change is approaching, the code disappears, and the tool table appears. Always with the same tool highlighted regardless of the upcoming tool number being requested. And, IIRC, the tool table display remains until the following otedautoz call, which dynamically sets the TLO, has been completed. But, I am not at all sure it is the LCNC tool table being displayed, I believe its the expected tool table from headers of the pcb2gcode generated files! Which is nice since the insert tool requester does NOT spec the size of the drill its looking for, but the text window does show the pcb2gcode expected tool diameter in the M6T2 line. No clue how that is done but it does appear to work correctly. Where people like me, without a tool changer, or as Stuart once said, a 2 armed tool changer, can lose track, having the popup display the diameter of the tool being requested in the popups larger font would be quite a usable bit of help for aging eyes. A 2.6.x hint perhaps? But I actually think the instant behavior is useful. In the long run, one more column in the tool table, that contained a code number that describes the tool, where 0=drill, 1=flat faced mill, 2=round nosed mill, etc, etc, would seem to be useful. 0-9 for milling tools, 10-29 for lathe tools.

Re: [Emc-developers] Tool Table and Wear offset Table
Yes, I think that a G41.1 or G42.1 will need to be invoked at the beginning of each cut depending on travel direction and then a G40 will need to be used at the end of each cut so the travel direction can be changed for the following cut. Lead ins are used to start all cuts so I am hoping I can invoke the G41.1 or G42.1 prior to the lead in and then cancel it at the end of each cut via a G40. That should make the CAM post pretty straight forward ( I hope! ). I did some testing with G41 and G42 yesterday and found out that a M64 P0 (Digital output On) cannot be executed while a G41 or G42 is active? I thought that was a little strange. I'm using M64 P0 to turn on the waterjet and M65 P0 to turn it off. Does this sound like a bug?

Re: [Emc-developers] jepler/rtos-uspace: a new POSIX realtime branch
I am surprised how long the LPT port has lasted. Many of the new Intel Bay Trail boards either have LPT ports or a header on the motherboard. Apparently the LPT port must be used by a lot of embedded systems. Otherwise why would they continue to include that? It seems like the PCI slot is endangered. Some of the newer boards are slotless. The cost of a spare motherboard seems slight to me considering the overall cost to implement a CNC system.IMO, if uptime is critical, put spare parts on the shelf and that solves the future availability issue for the most part.

Hacking the CAN bus of a self-parking car would be an interesting solution. I agree. Seems like a mismatch to me. This vehicle is pretty simple. No vision, no radar. It only operates in a clear space. I can't find any RC servos that are close the the requirements. So that becomes an issue.

Re: [Emc-developers] Setting tool length vs touching off Z every time [was: g43 and modal commands]
A tool length and width and shape probe is needed for some types of tooling. For some a camera can be used but beware of camera optical axis and resolution accuracy etc For best quality you need to detect the run out so you know the effective diameter too. Dave Caroline On 19/03/2014, Ed Simmons e...@estechnical.co.uk wrote: On 19/03/14 00:57, jeremy youngs wrote: also modifying the work offset affects EVERY tool , (further bad juju) , however understanding the limits of many of us on the list without toolchangers and holders i use the touch off method, while not perfect it has sufficed for anything i do at the house , i would NEVER allow that in a production environment , in fact i only allow 2 methods in the shop 1 touch off a block , 2 use a toolsetter , anything else is just asking for the inevitable crash , especially when changing shifts ( dont ask how i know ) :) Is there any meet-in-the-middle between the touch off Z every time approach and having tool changer with repeatable tool length? I fully agree about dangers of changing work offsets, but as we see it, we have very little option with collets and tiny tools. Our situation here is that the machine is used mostly to cut flexible plastic panels - these need adjusting when being set in the machine for optimal flatness (stupid bendy stuff!) and always end up at different heights - sometimes approaching 0.2mm variation between the height of successive panels placed into the same work offset. The depth of the engraving is very sensitive to this, so our routine is to fit the panels, then one by one check each for flatness and touch off Z for each panel's work offset to the correct height by probing onto a plate placed on the panel. The gcode for engraving the text is a subroutine that is called at each of the work offsets in turn. The tool is changed after the engraving is completed for a 2mm single flute straight cutter to make the connector cut outs. Here we cheat a bit, since the depth is much less important (as long as the cut is right through the panel) we just touch off the height to the first offset. In this case, the pattern of connector cut outs is replicated for each panel laid out on the grid of our mounting plate. The whole grid is in G55 offset to avoid the need to individually adjust the heights for all the work offsets for this step. However, since changing the tool invalidates the height in all the work offsets, this isn't so important anyhow. Would a tool length probing station help in any way? I still think we'd end up probing the Z for all the work offsets each time we fit panels... From time to time I accidentally touch off the wrong axis when setting up these panels, much cursing ensues. The grid of panels is at least regular and easy to recover from this by going to XY 0,0 in an OK work offset, then touching off X or Y to the correct value for the messed up work offset. Every time I do this, I wonder if there's a good way to avoid this mistake. Any bright ideas would be gratefully received!

you do not know apreori if you should do a deepcopy or shallow (ie do

Other than that, it is a very useful feature.
Absolutely.
Structure copy is only a shallow copy (you could think of it as just a
shorthand for memcpy).
C++ allows you to override the assignment operator so you can use that to
do deep copies. But for C, you're probably better off to code a helper
function if you want a deep copy.

The shop owners cousin is available and lives near the shop but has never run a machine tool before. The shop owner convinces him to work in the shop and run the machines and make the parts while he tells him what to do over the phone and via email. Another issue, the cousin can't read blueprints.

One of Gentoo's strengths is the use of the explicit dependency graphs defined in the ebuilds. This allows you to check daily if there are any updates on your system, and to easily update the entire system. Portage also give you very fine control to lock out specific versions or overload their build flags without having to resort to figuring out all the command line arguments for config, make, etc. My personal experience is that Gentoo is a pain to do the initial setup, but after that it is breze to maintain. The machine I am working on at the moment is 7 years old, and running of the same basic config that I have updated and maintained daily. I should also mention that it is not required, but it is nice when the system tells you that there is a new/updated version of the kernel, LCNC, or even more insidious a ssh upgrade due to some security patch. Basically, it comes down to the fine level of control, repeatability, and reportability that the tools allow. I will have to think a bit to see what might be the advantage over Debian or Ubuntu. One interesting point someone pointed me to was that Google's Chrome OS ditched their Ubuntu based distro and rebased it on Gentoo. Not sure what motivated that, but I would guess that it was the ability to control every single package build on the fly.

Fred Proctor bought an expensive ($2000 per node) real time extension to Windows (I'd guess it was NT) and built something very close to our current latency test. It was HORRIBLE, and as far as I know, the project stopped right there. I think there were latencies of up to one SECOND several times a day. They tested Linux and an early RT-Linux patch and were pleasantly surprised. There was a DEMO program that implemented the ancient keystick (or was it TkEMC) GUI with a little bit of stuff behind it, that ran on Windows. But, it was not even anywhere like the sim version of LinuxCNC, it had a dummied-out interpreter. Jon -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.

But I would argue that this should be a pull operation -- Lets say you have a branch dealing with TP, then you get it working and tested by a couple of people, then you send a pull request to Seb. He then merges it back into master for inclusion and wider distribution and testing. ah yes non compilable code is a no no for sure. That is surely a thing nice about the buildbots - you find out about this quickly. I've had code work great on my system but breaks on another. Right now I can push a 'feature' branch to the buildbot to check it before including it in master - but I have push access. fair enough. I know that non-compilable code will get pushed from time to time (as shit always happen), but I think the point is clear. I should have explained the release manager part better ( only so the discussion assumptions are close to reality ). In my experience here, after a release candidate in branched off, master is free to be developed. There has been little restriction on what goes in and no one-person merges work in to it. There is no master manager. I think this is a problem. How about the next (future) branch release manager manages master until they spin off. So, if there is anyone willing to take over what will become 2.7 or 3.0, they manage master until we spin off the one after 2.6. Who is it that is championing the universal build (or is that something still slated for 2.6)? Seb? The release manager decides what else gets included in a release candidate. Agreed. Usually only bug fixes, sometimes small atomic features can be added, eg new components. This is the stability and release phases. The pull request to master is a problem, as we have discussed. with no master manager or other point of contact, there is no way to make this happen or find out why it won't or can't happen. If you have push access you can do things right away, if not . Hopefully we can make this situation better as we go. It will not get better until until some change is made. What other ideas are there to fix the issue? Setting it up on the buildbot is an interesting idea. That would imply that each test branch needs a champion to setup the buildbot, and thwack the code. It would be a little extra work for them, but would save Seb some time if it is agreed that after testing and the pull request comes that the test branch is as close to the current tip of the master as possible (so very few changes necessary). When I said a test branch, I meant a single branch. so there would be the current release, master and testing in degrees of less stability. fair enough. I was thinking that multiple test branches would allow single ideas to be pulled in. I doubt that there will be more than a few at any given time, but this too needs a manager and I would suggest that it be the person that is championing the idea (because they have the skin in the game). In my mind the difference between master and testing is that testing work doesn't automatically go into master. Is this how Debain's SID works? This could backfire too as stuff could get left in testing forever if no one takes the reins of moving stuff to master. that is why I suggest designating champions. Interesting you say that. 2.4 has about 19 unreleased bug fixes. The last fix was 19 months ago. I would say support has ended for it. This needs to be formally decided. Also, if there are only 19 unreleased bug fixes, how much time would it take to release them, and formally put the code to bed. Before doing that we should ask if there is anyone who REALLY needs 2.4, and is willing to commit some resources (time or money) to have it continue to be maintained? Chris Radek is the release manager of 2.4. My personal feeling is 2.4 should be considered end of life. Releasing the last bug fixes would be fine (most are actually doc fixes) Chris? Since you are the release manager, what are your thoughts? Are you up for a final buttonup minor revision and then EOL 2.4?

The LEDs and progress bar activity is looped back remotely, i.e. involving HALrcomp interactions. -- The HALserver is still in Python, ca 300 lines. There were some minor changes to gladevcp.py and makepins.py, plus ca 250 lines of Python in hal_glib.py. The extra HAL support for remote components is 580 lines of C. The protobuf and zeromq components are as distributed. There are no significant API changes as of yet meaning existing gladevcp applications should hopefully run unchanged, or with minor retouches (the need for idle handlers should mostly go away). The EMC widgets are not yet working, this is pending 'remotifying' the linuxcnc Python module of which some beginnings are in place. The protocol document will see some minor clarifications and a clearer separation into the two channels (to/from HAL) which are in fact separately usable. The implementation still needs to address a few technicalities, like firming up dead/live peer detection and startup and tracking of stateful input widgets like togglebutton, but that is similar in nature to persistence which is already supported, and not a protocol issue per se (you see in the video the togglebutton is remotely tracked; the scale isnt - yet). Since this is event driven and polling happens in a single place, and once for each monitored object only (halserver), as expected the UI idle load drops to next to nothing. So: it's possible, it wont require wholesale changes, it is doable without writing gobs of new code, and the stack looks usable. - Michael ps: please understand the status of this - the protocol is fresh, the code is still warm, and it will take a while until this is shaken out, packaged and documented.

Here's a performance comparison between the stock blends and circular arc blends: http://www.youtube.com/playlist?list=PLTi4ghj9Dyajbv4F4P4TxWXpgPgvqrhA- For a random, kinky path with short segments, the difference is pretty dramatic. The average speed is about 3ipm with stock blends, vs. 7 ipm with circular arc blends. Here's the branch on github: https://github.com/robEllenberg/linuxcnc-mirror/tree/feature/3d-blend-arc-techdemo The algorithm itself is working, so I'd like to make sure the implementation is robust too: - Edge cases and checks such as minimum / maximum blend radius - Eliminate any conflicts with other machine modes (haven't found any yet, but I wouldn't be surprised if there were). - How much difference does optimization depth make? Depending on machine config, much more than 10 segments might not matter - Parameters stored in INI file and passed in via commands - Profiling / RT timing performance, especially on slower machines (tpAddLine has a lot more work to do now) If you have ideas for additional features or tweaks, or would like to do some testing, definitely let me know. In particular, I'm looking for feedback on the following areas in simulation and/or hardware: - Are synchronized motions (CSS, rigid tapping) adversely affected by my changes? I don't have a spindle pickup on the sherline, so this would be very helpful to test this on a machine so equipped. - Position accuracy at high speed, perhaps a comparison of G2/G3 arc vs. a circle made of line segments. - Profiling / timing performance on a real machine (simulation profile results show no more than a few percent difference, but I'm not sure how representative that is of hardware conditions) - Qualitative performance on high-acceleration machines. Can the machine hit speeds so that trapezoidal profiles aren't smooth enough? So far I've tested 3D motion, but it should be able to handle motion in all 9 axes (by falling back to parabolic blends). I'd recommend running your programs in simulation mode first just in case. -Rob -- Android is increasing in popularity, but the open development platform that developers love is also attractive to malware creators.

Neither I'm going to waste my time on making dumb BBs nor there is a need for just a new one -- chinese stuff is abundant and dirt cheap and there is no shortage of that crap, you just whistle... Even if someone WAS going to make something new it is futile because you simply can NOT compete with chinese crap. Sure, there is one other way -- one can deliberately deceive those who don't have any knowledge on the subject by telling them his controller is very advanced and can dance polka, anticipate Mach output, interpolate on a single point etc so illeterate people would buy his stuff. Unfortunately I'm not of the used cars salesman type so I simply can not do that. I'm an engineer by trade and by calling -- I get my endorphins from designing and making things and I'm addicted to it. There is simply no place in your Mach world where I can satisfy that urge to make new things to feed my addiction. I'm getting off your ship not because I'm angry but because I'm bored and there is nothing for me to do here. There is no shame in staying in hobbyist market.

[Emc-developers] Trouble in Mach3 / Mach4 land..
There has been a heated exchange the last two days on the Mach3 email list that some of you might be interested in.. The discussion centers around the Mach3 planner and the Position - Time data that is passed to a 3rd party plug in when Mach3 is used with an external motion controller. Basically the new Mach4 uses the same data interface and Sergey is not happy about that..as you can read below. It appears that Sergey asked Brian to supply a new, improved interface and Brian is not doing that.. Brian Barker owns Artsoft - the supplier of Mach3. A new version of Mach3, called Mach4 has been in development for years. Sergey, I believe, is the owner of KSI Labs and has a loyal following.

There are plenty of people who are hobbyists and they are pretty OK with what your software can do so they simply don't need anything better. Keep serving them, it is a noble task. It is simply not a place for me. I'd rather go where the big boys are and where real athletes compete instead of staying at general fitness group for those who is physically challenged or not especially fit. I will keep supporting my hardware on Mach3 but won't do anything for upcoming (?) Mach4 -- there is simply absolutely no need for Mach3 users
