Re: [Emc-users] TOT Bamboo Fly Rods
Ah, bummer. That one looked to be in pretty nice shape, and all the sections were the same length. My rods go for $1500, $1600 if hollow built. Hollow building is done by fluting each individual strip, so that the center of the rod, when glued up, looks sorta like a 6 leaf clover (of air). It's done to lighten up the larger rods, but has an interesting side effect. With less mass, the rod action seems to quicken up a bit.

Of the 3 machines live on my network right now, none of the services files

listed at 10080-10083 in all 3 lists.
What SHOULD I be seeing in those files to differentiate the 2 ip versions?
Thanks Mark.
Cheers, Gene
Gene,
I meant to say either inetd.conf or xinetd.conf. In the /etc/services
file there should be a line similar to this for amanda with the correct
port number:
telnet 23/tcp
In the inetd.conf or xinetd.conf you may see a line similar to this:
telnet stream tcp nowait root /usr/sbin/telnetd telnetd -a
Depending how xinetd is set up, you may have the directory
/etc/xinetd.d, where the configuration files
for the services are at. In that case, you may need to create a file
called amandaserver
which includes statements similar to this:
# default: on
#
# description: Amanda services for Amanda server and client.
#
service amanda
{
disable = no
socket_type = stream
protocol= tcp
wait= no
user= amandabackup
group = disk
groups = yes
server = /usr/lib/amanda/amandad
server_args = -auth=bsdtcp amdump amindexd amidxtaped
}
If this is the case, you don't need an entry in the xinetd.conf file.
That file will source all the files in the xinetd.d directory.

But they are ordered, hold for complete shipment mode. I managed to get the LM317T's mounted wired, but the si rubber insulators I stripped out of a defunct Antec PSU aren't that good, the LM317T feeding a PSU fan about 17 volts measures 097F on the 317's tab, but only 71F on the other side of the 1/4 alu plate its bolted to, in a 68F room. With no drivers hooked up yet, it takes about 20 seconds for the fan to start slowing down, and another 20 secs to stop after I toggle the power switch back off. The filter is a pi section with an unknown choke inductance 20k uf on both sides of the choke. That particular fan apparently has a poorly timed commutation, it looks like it's trying to crowbar the supply for about 200ns every time it commutes to the next coil sequence. I may see if there is a smallish choke in that PSU that will shove that stuff back into the fan, it might reduce the draw by a few percentage points. Silly Q about lathe mode.

Mark While I tend to agree that we need to polish up our sales pitch and material, one of the things I think we need to emphasize is the level of support, I think it is fantastic compared to anything I've ever seen before, where software packages that cost $2500/month, often have bugs that don't get fixed till the next annual, send lots more money, update. That is the usual situation at a tv station, where the software that handles Traffic, is the heart and soul of the business model. LinuxCNC with its random releases that to my knowledge have only once or twice not been 100% backwards compatible, has amazed me. But I guess I'm getting used to the Linux way of doing things. Take amanda, the backup program, where I have been playing the canary in the coal mine for the bleeding edge development versions for nearly 10 years running it for 14. Only one, non-compatible update has ever taken place and that was at least a decade ago. It gets broken by support library changes regularly, most recently by a glib-utils update, but was fixed in 3 days. That rapidity of fixing things we have no control over means we get broken more often than an M$ product is, but we still fix it 10x faster too. IMO, this rapid response to problems, should be quite near the top of the list of advantages to choosing LinuxCNC. Cheers, Gene Gene, Support is one of the things I mentioned, and IMO, probably one of our more important things to market. We do have a bunch of different channels available for support, from this mailing list, to the IRC, to our own forum and to the LinuxCNC forum on CNCzone. Without that support, I'd never have gotten my machine up and running.

Re: [Emc-users] The future of LinuxCNC mailing lists and bug tracking
On 2/19/2012 8:23 AM, Jeff Epler wrote: In the board's original announcement of the rebranding of the project as LinuxCNC, we mentioned a future renaming of the SourceForge project, so that our mailing lists would be under the LinuxCNC name. However, the board has not yet filed this renaming request with sourceforge.net. Instead, we are soliciting community input on the future of our mailing list and bug tracking system. The board sees two possible options: * Keep mailing lists and bug trackers hosted at sourceforge but under a new group name. Advantages of this choice include that most maintenance is done by sourceforge.net administrators. Disadvantages include the relatively feature-poor bug tracker and the ads displayed on all mailing list messages and project pages. Also, some disruption is expected in the course of the sf.net project renaming process. It is possible that some information will be lost during the rename process. * Administer our own mailing lists and bug tracker, eventually closing the sourceforge project. Advantages of this choice include a more powerful bug tracker (probably bugzilla), ad-free mailing lists and project pages, and the possibility of an overlap period of sf.net and self-hosted services. Disadvantages of this choice include greater administration requirements and the need for users to create new accounts with the new services. Furthermore, it is unclear whether it will be possible to migrate data from the sf.net tracker to a self-hosted tracker, though the board will investigate this matter further. If we choose this option, the board accepts the ongoing work of hosting these services. There are no extra monetary costs anticipated for self-hosting these services. Ideally, this discussion will result in a clear consensus of the community. If there is not a clear consensus, the board will take into account community comments and make a decision by vote but not before March 5. Yours, The LinuxCNC board of directors If it's feasible, I would lean towards option two. I'm a system and network administrator in my daytime job, and I'd definitely volunteer to help with the changeover, and ongoing maintenance of our stuff. I manage several bulletin boards, have run mail servers and mailing lists, and I'm quite familiar with setting up and configuring web sites, CVS repositories and lately wiki forums. With all the help I've gotten from all the folks on this list over the years, it'd be a way for me to help pay back for all that help and assistance, and I'd be more than happy to jump in with both feet.

My base_thread is 20,000 now, which would I would think, show up as several percent of the 2nd cpu, the red line in the ksysguard system tabs display. When linuxcnc isn't running, I see, possibly at 10 second intervals, a barely visible spike to perhaps 0.5%, with isolcpus=1 in effect I've no clue what that might be. With linuxcnc running (without the taskset launch), and carving the logo, I see an occasional spike to perhaps 2% at about that same 10 second interval. And a spike to maybe 5% if I do something in axis like adjust the feed override slider. With a 20 microsecond base thread, and a 3 microsecond reset timing set in the .hal file, ISTM that core 2's usage should be higher that that. I do see in this utilities process list, an 'rtkit' that is caught using 2 or 3% very occasionally. And the hal_manual_tool_change shows up too. Keyboard response from here of course includes the network lags, but seems good enough that at a .28ipm jog rate, I can jog it half a thou with a quick tap on an arrow key. This, with a 30 microsecond base thread on the old machine, would not have been possible because it would run on for several seconds after the key was released. Whether I get the same results from its local keyboard remains to be seen and may be the result of running axis on a remote display not burning cpu cycles for the local display since this boxes nvidia driven display is probably 20x faster than that machines intel based display is. From this I get the impression that an additional box with good gfx might be a huge advantage even if the network cable was only 6 feet long. Discussion? Am I using the wrong tools to track this?

Re: [Emc-users] Axis enable pins
On 4/23/2011 12:38 PM, Kirk Wallace wrote: From a brief search for HY-TB4DV-M I found this board is likely to be based on the TB6560AHQ: http://www.toshiba-components.com/motorcontrol/pdfs/TB6560AHQ_AFG_E_2003_20080407.pdf Short URL: http://alturl.com/gygw6 I started a couple of different replies, but they got too long. I think the crux of the problem is that the basic parts of the driver board are there but are near their performance limit. In these situations, the user will need to have a good understanding of how the board works to recognize were the problems might be and compensate for the faults. For a beginner, this can be a lot of extra work, or a good way to learn about electronics. If you just want to bolt together something that just works, consider not using this driver board. If you want to build and modify more CNC machines, you will need to learn all the details anyway and it's best to learn on something that is inexpensive. I would tend to start with the EMC2 parallel port and verify that the proper signals are created at the port, then look for these signals as they go through the driver board. This means that you will need to become familiar with most of what is in this link: http://www.linuxcnc.org/docview/html/hal_parallel_port.html These might help too: http://www.epanorama.net/circuits/parallel_output.html http://www.beyondlogic.org/spp/parallel.htm It is easy to damage a parallel port while experimenting, so I believe it's best to get a couple of PCI parallel port cards to play with so you don't burn up a motherboard port. Check these for more: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?NetMos and other parallel port cards here: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2_Supported_Hardware Being comfortable with using HALscope and HALmeter will help. Check out the scope and meter sections of this link: http://linuxcnc.org/docs/html/hal_tutorial.html Instead of working with HAL from a terminal command line as covered in the above link, sometimes it's easier to copy a basic stepper configuration while in the EMC2 start screen and modify the .hal file to free up some parallel port pins and use them for experimenting, such as using the mist button to turn an LED on and off, or toggle a connected to the driver enable input on and off while checking the signal at the driver chips with a voltmeter. The above covers just a bit of what you'll need to know, so you will most likely need to come back here and ask more questions, but that is what the list is for. Also, the more specific a question is (one or two at a time), the easier it is to answer. There are also a couple of rather long threads of what folks had to do to get those boards working correctly on CNCZone under the General Electronics forum.

They tend to be really quite simple, following the driver chip suggested layout exactly. The driver chip manufacturer's datasheet is probably more useful than the supplied documentation. It is then a case of seeing which pin on the DB25 connector goes to which input pins on the driver chips (they may go through an opto-isolator chip, so that is probably a 2-stage process with a multimeter).

The difference between you making do, and somebody else buying those boards, is you're ready, willing and able to actually troubleshoot the problems, and fix them. There are a lot of unsuspecting folks buying these boards, and having nothing but problems with them. And a lot of them have little to no grounding in electronics, and don't know how to troubleshoot and fix these boards.

Mark Single channel servo (clone as necessary): - power_supply | emc - motion_card - servo_amp - motor ( dc | ac ) | | --- encoder For dc servos it is nice to have a tach for velocity feedback although cradek has demonstrated a nice way around that. This usually gets you several things; increased speed, freedom from mid-band resonance, usually lots of I/O for limit switches and probably more attributes I cannot recall at present (too early in the morning). Setting up a servo is not as daunting as one might think. It does help to put a channel on the bench and learn about it while it is not connected to an axis ( less stuff to damage if it does something unexpected). ;-) I would never connected a servo to a real machine without having e-stop limit switches in place and tested. Please don't ask why I think this is important. Halscope is invaluable once you start on the real machine. Thanks JMK! :-) HTH Dave Thanks Dave and everyone who's contributed. It's a consideration for a future update. Right now, the machine is working fine on steppers, but I thought with servos, I'd get a better torque throughout the speed range, and maybe a little more accuracy on the positioning. One thing I haven't taken into account is the dual-stepper setup on the X axis. From what I've read, and talked about on the IRC Channel, it's a lot more tricky to home a dual-servo setup, whereas with the steppers, I have just one home switch on the X axis.

After much eBay and web surfing, I couldn't do any better than the $56 MPG, but no WAY I will pay $179 for a cheap plastic box with a couple switches and the encoder. I did set up a CNC4PC pendant for a guy, and I was not terribly impressed with the thing.

Jon I haven't used a pendant, but I don't see myself using one single handed. I would probably make a few points around the machine to mount the pendant where I can reach it, but keep my eye on what's going on. That's why I think the feel of the detent feedback is important. I would look to the major CNC machine makers for insight on this. They have decades of experience and have weeded out any of the fancy stuff that doesn't get used in the long run. You might be able to one-hand the button pushing on the pendant, but I'd love to see a video of one handed MPG movement if you aren't near any of those handy mounts. ;-) Depends on what you want out of a pendant I guess. I find the MPG wheel very handy except on long jogs. And Stuart has a machine that has some really long jogs possibly. Other than the MDI, that's where a joypad would come in really handy. I've been using the MPG heavily while I mapped out my vacuum hold down. I've been taking hold-down height measurements every inch the length of the hold down. One turn of the MPG wheel = 1.000 when the MPG distance knob is set to x 100, and the Z axis moves .0001 for every MPG click at x 1.

If it decreases a little bit, no disaster should happen, the knee will not drop, the system is self braking etc. Instead, current is provided to the motor, the not enough to move the rotor, but enough to heat it up too much.

In local wireless networks, /CA is used (Collosion Avoidance) instead of /CD. Other Bus protocols are based on the same idea such as CAN bus (CSMA/CR, Collision Resolution) and others. All these protocols have in common that they are asynchronous and data transmission is randomly timed, depending on network load. Just the same especially with serial busses like USB. Since EMC is based on exactly timed pulse generation, there is PRINCIPALLY no use trying to adapt it to the protocol systems mentioned. Why not stick to the parallel port? Best regards Peter Blodow Peter, I work on a daily basis with Ethernet as a system and network administrator. We're talking about a Real Time Ethernet, with a dedicated master and slave network interface, which should preclude any worry of collisions on a duplex connection between the two. Modern systems with full duplex connections no longer really rely on CSMA/CD. As defined in 802.3, that's just one of the protocols that have been used, not the only way. The reason we're talking about Ethernet as one of the possibilities for communications between the computer and the controller is the possibility of the ultimate demise of the parallel port, and the difficulties of real time communications on the USB bus. So, Real Time Ethernet ain't quite your Granddaddy's TCP/IP or USB protocol. If it can be worked into a real time communication scheme, unlike USB, it may be a possible alternative to the parallel port when the parallel port is no longer supported. And, if it's a dedicated port, like the parallel port is, and can be controlled by the Real Time kernel, it can handle the timed pulses in 100 Mb, Gig E, or 10 Gig E depending on the network interface that's supported by the software.

So although yes, the universal driver can run the network in real-time, it's not able to run in real-time under a real-time OS. For some reason, I'm not quite getting the distinction. What's the point of a RT network if it's not going to run under a RTOS? (This reminds me of Bob Newhart's classic turn as Major Major in Catch-22 who would agree to see people in his office, but only when he wasn't there:) http://www.youtube.com/watch?v=gwT-_uCEMiA So maybe rtnet.org is not re-inventing the wheel after all? Additionally, RTnet.org mentions an RT-Firewire, so maybe those who have been wanting EMC2 to run over USB would accept Firewire? Eh, Firewire usage is fading faster than parallel port. My latest laptop and desktop systems don't have any Firewire ports on them Or, back to Ethernet, RTnet.org lists 12 supported NICs: http://www.rtnet.org/doc.html I wonder if EtherCAT is trademarked? And we (and slave card makers?) might have to pull out all the EtherCATs the way that CentOS has to pull out all of the Red Hats out of otherwise GPL'd software? And only mention the upstream source provider? Also, EtherCAT lists only four NIC cards as specifically supported. (I'm guessing this means running *with* a real-time OS? Not sure.) Could be our biggest problem is going to be the slave port. Now, we're using a relatively simple and cheap parallel port breakout board to the drivers. How do we inexpensively make a slave card work RT at the driver end of the link? It needs to be able to accept the signals from the master, then convert those signals to step/dir, or servo loops, and in the case of servo loops, be able to communicate the loop back to the controller. I consider a large number of supported NICs to be a feature, not a drawback. And I think manufacturers would agree, if we can get to the point where the NICs are supported generically(?) in some way so that it's not much extra work for the slave manufacturers. Or, if not, then pick a couple of popular ones and support those. And just to clarify a point, it wouldn't bother me at all if the EMC2 master PC had to have at least one real-time-only network interface in this proposed scheme. I don't see why we want to make Samba and BitTorrent available over the same network as the CNC RT control signals. Even if they can be tunneled or whatever. The RT network should IMHO connect only EMC2 and the CNC machine slaves, nothing else. NIC cards for PC's are cheap, and the more that support RT ethernet the better. The big issued is going to be what do we do on the other end. So the way I see it we have to first plan a way to get simple, fast, RT I/O working from a NIC in EMC2 with an eye toward how to build the remotes, and if they can be EtherCAT or RTnet.org (or anything else) compatible, great!

[Emc-users] Talk to me about comp_file
Was cruising through the doccy's today and came across comp_file in the config ini section, and had seen something thta piqued my interest whilst perusing the EMC2 section on CNCZone in answer to somebody else's question about backlash compensation. Chris M, chester88 on CNCZone said thus: EMC does simple backlash compensation and sophisticated mapped compensation (which requires homing to a accurate consistent point). little bit about it here: Basic Configuration (http://www.linuxcnc.org/docs/2.4/html/config_ini_config.html#sub:)[AXIS]-section. For my own nefarious reasons, I became interested in this, with an idea popping into my head. For those not familiar with my machine, it's a two axis (X and Z) saw beveling machine, which cuts tapered triangular bamboo strips out of rectangular stock in one pass, starting on the thin end and cutting deeper into the strip to finish on the thick end. With that in mind, I use a vacuum hold down to keep the strips in place, which is 3/4 wide by 60 long. I've been draw filing with a nice expensive Vixen file and some amateurish scraping, and so far have gotten most of the surface of the hold-down/bed within .001 - .002 of my 0,0 point. Now, my nefarious reason - I'm realized that a career of hand scraping is not for me. I've mapped the entire length of the hold-down/bed with a depth gauge, and know, for every inch of X, the difference between the current station and the 0 point for the Z axis. For instance, I set my depth gauge to read 0.000 at X0. At X1, for illustration's sake, lets say Z is .001, X2 - Z = 0.0005, X3 = .001, and so on and so forth for the entire length of the hold-down/bed at 1 intervals (had to do this so I could get this close while filing and scraping). The readings of the depth gauge are repeatable, so I'm pretty sure the depth gauge is giving me accurate readings. My question is, can comp_file be used to map out those inconsistent heights in software, so that I don't have to file and scrape anymore? ;-) Mark -- Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!

Re: [Emc-users] Cinci/Enshu progress report
At 10:53 PM 9/28/2010, you wrote: Gentlemen, I am a happy camper. Jeremy came in my office with a quiet voice to give me a report on how the Cinci cut the big plate with all the holes with a +-.002 location tolerance. I thought OH NO we have problems. He then smiled and said it nailed all the holes. There was one dimension out of tolerance. A hole to hole location of +-.001 on a distance of between 25 and 26 inches. It was -.0015 or .0005 out of tolerance. This is in the realm of temperature causing the tolerance fluctuation. I think maybe the design is a little tight toleranced as quite a number of the holes are bolt holes. Bolt holes with a +-.002 location tolerance are a little overdone. Jeremy said he thought this is the only machine in the shop that could do these parts. What an endorsement of EMC2. I heard someone say you cannot make a silk purse from a sow's ear but I am not so sure anymore. The Enshu is basically done. It is ready to make parts. This afternoon I was looking at how to get an encoder on the spindle. After removing the spindle cover and finding it would be a major undertaking to mount and connect an encoder we started looking at the spindle drive. The spindle drive is a full servo with feedback from the spindle motor. Instead of encoder feedback it has resolver feedback. This feeds directly into the spindle drive. Reading the manual lead us to check a few pins with a scope. We found encoder A and B pulses on two pins and an index pulse on another pin. This will allow feedback into EMC and give me control of the spindle as an axis. I will be able to drive the spindle as an axis with the MPG. I am not sure exactly how I want to control this. I will be able to read the index pulse after every gear change to orient the encoder to the spindle. Do I want to have a linear scale or a rotary scale? This has 4000 rpm and I am not sure how many pulses/rev this will have. Ideas, comments welcome. I have the video camera ready to record some motion/cutting and tool changes. EMC2 rocks thank you very much Stuart Stuart, Schweet! I don't know why, but I really like watching that machine go through it's paces. My daughter was a huge Transformers fan when she was a kid, and I guess it just reminds me of one of the friendly ones. And Ms Fox is kinda cute too...

Ian, Yabut... Mount it to what?
