Using the ilowpass, you can actually hear the last few integer steps come out after you stop moving the MPG. The way I have it set, it takes about 3/4 second, maybe, for the full commanded movement to be completed when you stop turning the MPG. When using it to step down/in when cleaning up a surface/edge, I depend on it to make the exact move as I count off on the encoder detents, and it seems to do it quite precisely.

I can't speak officially for Tormach but indications are that Tormach creates all of design and specifications and outsources the manufacture.

Re: [Emc-users] MPG ilowpass vs limit2/3
Thank guys. I completely missed the integer in/out part. I had sort of figured out it was trying to increase apparent resoution from what Peter and Jon said and now that makes a lot of sense why. We'll give it a try. Though, Im now curious as to how a filter will play along w/ the velocity mode setting. As long as the filter rate is reasonable I guess the output isn't still settling for a good time after the wheel has stopped.

[Emc-users] Trouble creating custom firmware for 5i23
Hello! I am trying to create custom firmware for 5i23 card. Machine has 5i23, 7i48 on P2 and 7i37 on P3. In addition to 7i48, I need 3 stepgens and at least 1 encoder on P4 connector. I created vhd file, Andy compiled it and in the end of this message is the error I receive on LinuxCNC startup. I think that the essence is described here: [ 107.276703] hm2/hm2_5i23.0: WARNING: this firmware has Muxed Encoder v2! [ 107.276713] hm2/hm2_5i23.0: WARNING: velocity computation will be incorrect!

Re: [Emc-users] Tormach mill, unique design or Chinese inside?
While it is just another Chinese built benchtop mill I think you will find that they designed it from the ground up including the CNC system to their own specs so it is quite different from most of the other benchtop machines available out there. It has a loyal following and some of the pictures I have seen of work made on them looks pretty good it is after all just another Chinese benchtop machine albeit with some intelligent design thrown in and some decent backing from the company. Don't expect any sort of on site repair or troubleshooting from them not at that price point. If you have a problem they will warranty parts but it is ultimately up to you to fix it and there have been bad ones come out of the gate. I did hear of one model that had so many problems they took it back and replaced it with another one but to my knowledge that has only happened once or twice. There are now several chinese built CNC machines that are similar in design that compete for the top slot in their niche market. Don't be fooled into thinking it is ANY sort of competition for a real machining center it is quite light duty and slow compared to even the wimpiest VMC's. There is no rigid tapping and it only has like 2hp spindle or so that is belt driven. It is all stepper based which is not a problem as it is designed properly apparently and their newest gen 3 model is smoother and faster than the rest. They fit into a price point that was sorta wide open as the next step up typically costs quite a bit more if you have to have new machinery. IMHO the best thing about Tormach is their ingenuity and willingness to keep producing tools and fixtures for their machines that make it quite interesting and capable for what it is. They have built a market where there really was none and done quite well with it so far. With the onset of other competing platforms it is getting more competition for their customers now as many have gone with some of the newer offerings from other suppliers. Personally if I were to spend anywhere near the money necessary to properly setup a Tormach machine I would just buy a used VMC and try to get a good one. I sorta did that myself and unfortunately wound up having to do a retrofit but it is still way ahead of the tormach in power accuracy and money spent even after the retrofit. Your mileage may vary.

Depending on the application you might consider using two software encoder functiions, one in "counter mode" working on a single channel to report speed, and a second one in quadrature mode to accurately measure position at lower speeds. I think this would work well for a lathe spindle, where feed-per-rev uses the spindle-speed-in input, and threading uses the spindle-revs (position) input. I don't think anything uses both, so if they get out of synch it doesn't matter. If you wanted to do this for an actual axis then I think it would be possible in HAL, by carefully combining the outputs of the two encoders (probably using latches and muxes) -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- WatchGuard Dimension instantly turns raw network data into actionable security intelligence.

Re: [Emc-users] MPG ilowpass vs limit2/3

The output of an MPG is an integer. If the jog speed is set to 1mm per click, then no matter what you try to do in the middle, the machine will try to move in 1mm steps. What ilowpass does is pretend that the MPG has many more counts than it really has. If you have a 100 count MPG and move it 1 click, then ilowpass with a factor if 10 will convert that into something that the system sees as a 1000 count encoder moving slowly through 10 clicks. I haven't used it myself, so I am not sure how the on-screen display of mm-per-click and the actual mm-per-click are sorted out. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- WatchGuard Dimension instantly turns raw network data into actionable security intelligence.

I use the joystick for large sloppy moves, and the MPG for precise movement. Both work well in those roles. The MPG is set to move .001", .010" and .100".
