Very poor extrusions IMNSHO. I have a router table with an A3 working area, using an extruded bed. The table itself is fairly flat, but twists if not clamped down to the bench. I simply shimmed the rails to ensure that the bed is flat using a sprit level, and I'm not seeing any bowing in the bed itself. The gantry rails also needed a little tweaking to ensure the other motions are parallel to the bed. Result, the cutter is within a few thou of level over the whole bed. I could skim the surface and there is 0.05" step on the slots, but jobs I am working on don't need that finer accuracy, and small jobs are certainly a lot flatter. Had I found the bed was distorted then obviously a new extrusion may be an option, but there is plenty of room to fit a couple of bars to the back of the bed to pull things square. The ends of the bed are already bolted directly to a large cross rail and it's these that get shimmed to level things and remove the twist. -- Lester Caine - G8HFL - Contact - https://lsces.uk/wiki/Contact L.S.Caine Electronic Services - https://lsces.uk Model Engineers Digital Workshop - https://medw.uk Rainbow Digital Media - https://rainbowdigitalmedia.uk ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

And not much has changed today. A few years back I was given a very nice STL model of a train wheel with the request to cut one. Bottom line ... totally pointless exercise. What I needed was the original objects that were used to create the model, and the ability to select both faces and construction lines which can THEN be used to build a set of gcode. At that time I was using tools like vcarve and cut3d and feeding in 2D drawings which provided the various profiles to be cut. Now I have FreeCAD in the toolkit, essentially I'm following the same process but in the one package of tools. Certainly the older packages are much better at some elements of the process such as say 'engraving text around the curve of the wheel', but FreeCAD has a growing library of tools that take elements of the object and produce the relevant gcode. At some point in the future we may well be able to tell a machining suite 'I have an XYZ mill and here is the part I need to machine'. It spews out a list of tools to use, cutting feed rates, and either individual gcode files for each tool change, although if you have one of those million pound machining centres with an unlimited tool changer then it could be a single file. At the moment we still need to provide the intelligence to decide - appropriate to our available tooling - just what order of machining is appropriate, and FreeCAD today does allow me to create parts from a scrap of paper with a sketch on to a finished part. Personally I find the drafting side of FreeCAD cumbersome coming from some 30 years of Autocad style drawing and THAT side needs some more intuitive developments especially when taking existing drawings as a starting point.

Not unlike early 'simple' gcode which could not handle arc's and cut them as a aeries of straight line segments. The 'accuracy' depends on the number of segments, so while 'pixels' is not totally accurate, it is a reasonable analogy. What you can do is slice an STL 'image' and then do the equivalent of a raster scan to convert lines below a certain resolution back to arcs or circles but I don't think anything has been written yet that would return the construction objects of the original model?

Anybody using the iHSV57-30-18-36 and worked out what the native resolution is? ... any feedback as to if it's even worth concidering? Thats a problem I will face for the second time in a bit as I've bought a pair of the 3NM stepperservo's myself. These are equipt with 1000 line encoders, I think that are actually 250 line encoders. So for the lathe, I will have to plug in the sprocket ratios and z screw stuff to get a usable z scale. But I faced a similar problem with my g0704 when I put an encoder on the top of the spindle motor because I had no clue what the gear ratio in the head of the g0704 had it either gear. I intended to get, and have but its failed at the moment, an index pulse from the spindle rotation. So I cobbled up in the hal file, a counter which gave me the number of pulses from the 1000 line on the motor, for 100 turns of the spindle, measuring for both high and low gears, so I now have a couple switches on the rim of the gearshift knob to tally which gear it is fully seated into which in turn control a couple muxes so the tach and such stay calibrated. By using a mux4 for the speed control I can also insert a very low speed commend when its not quite seated in either gear. So I can reach up and shift gears when its running and its turning very slowly, the next gear flat faces mesh perfectly, and the selected speed resumes when one of the tally's goes good. That counter is still in the hal file, but commented out. and I just put a copy in my web page for you, or anyone else, you can get it all from my site in the sig, click on that and when you can see me & the missus, add lathe-stf/ to the browsers address bar and ENTER. You should then see another subdir named GO704-5i25-7i76/, click on that and help yourself, that is a copy on the config dir for my GO704. The main GO704-5i25-7i76.hal contains this counter. Copy it, fix the missing addf's etc. I used halshow's command line to reset it for each run, and a halmeter to read what it said. When reset, it counts indexes from the third to the 103rd, for any axis you feed it from that has an encoder, so divide what the halmeter says when it stops counting to get the actual number of pulses for one turn, divide by 100. I hope this is helpfull, Lester I get exactly where you are coming from, but I think I've got a slightly different take on things. I have found reference to the iHSV57-30-18-36 having a default of 4000 and that being '1:1' so this suggests the motor has a 1000 line encoder ( 4000PPR ) but I would prefer even just the 1250 line encoder to restore some of the resolution lost moving from the 20TPI thread on the original leadscrew over the 3mm pitch of the ball screw ... I suspect now that the 2500 line encoder may actually be too high a frequency for the built in electronics which is a shame and perhaps that is where we do need to use LinuxCNC to close the loop using faster hardware than that built into the integrated servos? I don't see the point of the 'serv ostepper' for anything other than the raw steps of the motor itself? Although I suppose micro-stepping may be more accurate if it's following the steps of the encoder? Stay well and safe.

The major flaw with ALL of this is that this kit is designed to reduce the reliance on the very commodity that was cheap in China and the rest of the 'developing' world - people?

The automotive sector which is a majority market for this kit just like the steel and other raw material industries below have more capacity than customers able to pay the prices? The days of buying a new car every couple of years just like a new phone, laptop and even mill or lathe are a thing of the past and it's time to make all of these disposable turnkey products into something that can be 'upgraded' which needs to be addressed, so we can add the latest improvements to last years kit without having to ditch the whole lot. Mine and the wife's cars are 10 years old - and Korean - and still going strong - my son bought a UK built Range Rover which has been off the road for months while he tried to find a new engine because the old one had failed with a 'problem these engines just don't get'. Unless we can make money from this kit for many of us it IS just a hobby activity? So paying inflated prices for the core components has to be justified when one can buy turnkey packages at a tenth the price knowing one will probably spend another tenth improving things ... which is exactly what I did with the 3D printer. And the basic kit from china was a quarter of the price of the same kit being punted under the banner of UK MANUFACTURE when it is nothing of the sort!

Having replaced a number of XP computers with Raspberry Pi's rather than the stupidly expensive M$ route of new hardware that could run current windows OS I can say I've not had any problems with the SD cards over several years now.

I'm running the same version of Mach3 that I installed on W2k and it does the job of running the mill perfectly for me ... and my customers. I keep saying I need to retry running LinuxCNC, but currently all the spare time is taken up with other jobs.

Not relevant ... The reason for switching to LinuxCNC is to better support multiple axis movement, but the Mach3 setups only need to drive 3 or 4 off multiple axis depending on which machine and rotary table is being driven. The 5 axis USBCNC boards will run all 5 axis but rarely need more then 3 running together, locking the spare axis down once positioned correctly.

Anybody working on a 'plugin' to work with PoKey family as an alternative?

The problem on the Taig is while one hits the end stop one end, you come out of the nut the other ;) But while stalling the motors looses position, it's not a particular problem from the safety point of view. Unless you put a finger in the way ... I've been looking to fit slotted sensors as limit switches to prevent problems at both ends of the table, with a flag on the bed which goes through the sensor (so no crush problem), and this is fine for limiting things, but it's repeatability is somewhat suspect for use as a home position.

The alternatives seem to have the same problems of repeatability. Using a hall sensor or optical one will give the same problems. Micro-switches are at least inherently mechanically constrained. I do look at the kit available and wonder if simply adding scale bars locked to the table aren’t a sensible compromise here? You have an absolute on on the machine which can be used not only to define a home position, but also to add limits based on the actual job? Which could be used where the natural home position IS in the middle of the work piece. I'm not talking about a set of inputs that are used as part of any closed loop control, but simply as has been done in the past, a check that particular points are in the right place. It could be used to measure the current backlash between the motion elements and the base machine, with a 'calibrate' cycle as part of the home process? Cheap Chinese readout bars can be used as one can easily compensate for the latency between readings, and I know in essence you are discussing the provision of a 'hardware' zero point on the axis, but as a cross check that the machine has not missed steps, or a flexible means of moving the machine to a fixed position to recover after a collision or stall it has merit? -- Lester Caine - G8HFL - Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk -- Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.

The quick answer here is YES the dongle is deficient in that it should provide at least a screen connection rather than just data. The adapter I use with the PTZ cameras has the duplex T and R pairs, but the T pair also doubles as the 'D' which is multidrop I/O and there is a separate earth to connect the screen. Certainly with the dongle you have linked to, stuffing the earth wire down the USB connector seems the only option, but also no provision to properly terminate a multidrop link. -- Lester Caine - G8HFL - Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk -- Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.

I'll cut the other comments and just concentrate on the basic problem with a couple of older closed loop options. The Microproto DSLS3000 is sold as a closed loop stepper driver, which works because the driver is only half stepping, and the 'closed loop' simply continues to apply power until it detects that the motor has moved. The problem with that is that if each step takes longer you have to have an interface back to the 'pulse generator' to slow it down. The Microproto 'fix' for that is simply to remember how many steps it needs and keep moving until the the right number have happened ... how ever long it takes ... you see the problem, and the axies can be up to 200 steps adrift before the fault signal fires. In theory LinuxCNC could be configured to monitor the buffering and slow down pulses, but I don't think anybody has added that as yet. On Mach3 it ends up with rounded corners as the change of direction happens before the first move finishes. The newer 'closed loop' motors are essentially using the same approach, but rather than simply applying the same power for longer, they apply a lot more power so as to try and avoid having to wait for the motor to catch up. What I am not sure about as yet is just how effective that is and just what the lag can be between a step pulse and the final positioning. The DSLS3000 approach is sold as a speed improvement with security that the axis has moved, but once the mill is actually cutting one has to drop below the open loop speeds anyway. Yes in free air one can move between cuts quicker, but the characteristics of the closed loop process have to be taken care of when setting feed rates. -- Lester Caine - G8HFL - Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk -- Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.

It is nowadays irritating that distributions made their own decisions on 'improvements' in the past. So Linux has a well deserved reputation for being 'painful to work with'. I've worked with SUSE Linux for so many years now that when I've come across sites using something else those little differences cause hours of head scratching on things 'that should just work'. Add in problems like Python2 vs Python3 and even 64bit vs 32bit and it does become something of a nightmare? :( A debate on 'cross platform' working should perhaps start with 'cross distribution' working. I've just finished upgrading the 'old' development machine from SUSE13.1 to SUSE 'Tumbleweed' since many of the nice new tools like FreeCAD and KiCAD will not load current versions on even SUSE13.2, remaining with older versions with known bugs.

My AutoCAD 2.5 dongle surfaced a while back and we used that up to Release13 but with cash flow tight and I think a £600 bill for next 'bug fix' it was time to get of the roundabout. £200 for TurboCAD Pro proved a good investment at the time.

My current 'production' suite is Turbocad15, EasyPC14, vCarve5 and Mach3 oldish build. It does what I need but I've got FreeCAD and KiCAD on the linux setup and have been trying to migrate, but neither now install as a latest version on SUSE13.1, bring stuck a few versions back, so I've just rebuilt the backup machine to SUSE Tumbleweed ... and that is even more of a problem.

Some things are controlled by local distributors who 'value add' but one does wonder at times. £332 vs £200 is crazy. For that price difference couldn't you import it for £200, pay duties, sell it for £280 and still make a nice profit while undercutting the guy selling it for £332? I must not understand what is required to get tech equipment into the UK. It is always a gamble if you end up paying duty on single items and to be honest I do tend to be more lucky from Oz than the US, but There could be around 25% local charges on any bulk shipment covering VAT and handling. I was going to say that the £332 would include VAT until I saw the final bill is actually £398.87 !!!

Enabling graphics in Linux seems to be hit and miss but basically there are no drivers for the Intel GMA 3600 graphics for Linux or XP but XP will run. to which Andy responded I don't understand the problem. I just installed the LinuxCNC 2.5 LiveCD, and it works as expected. What do you mean by enabling graphics? I have only used it on the VGA connector, (plugged into my TV, actually) but I get the normal Axis interface, and can run glxgears, and mouse/keyboard response is entirely normal. I'm curious about the difference between Andy's remark entirely normal and your remark slow and the resolution wrong with the generic driver. Is it related to VGA vs HDMI or perhaps to Andy apparently running Ubuntu 10.04LTS (LinuxCNC 2.5 LiveCD) and you running 12.04LTS? I did establish that the problem was mainly related to USING the HDMI socket with a high res monitor. Drop back to a nice 1024x768 VGA monitor and the LiveCD does load fine. But I relegated the DN2800 board to a job that needed W7 anyway simply because I could not rely on it. The XP drivers still are not available, but as long as you use a low resolution monitor then the generic drivers are fine. The PV530A-ITX has proven reliable and paired with the Dual PCI case gives a nice package at the moment.
