[Emc-users] BeagleBone Black, ready to run a large 3 axis mill?

[Emc-users] BLDC - not smooth rotation with hostmot2 and 3-phase bridge
I started to test IRAM module with MESA 5i23. I use TPEN6_6 firmware and bldc module in n mode. I am rotating it slowly (setp bldc.0.frequency 0.2). PWM outputs are true sinusoidal (checked on scope), but motion has some smooth (non-linear) parts and stop parts. BTW, I can't use bldc n6 mode, because I don't have where to connect A-high-value, A-low-value, .. because bldc component has A-value, .. pins only. When I use n mode, the motion is not smooth and it does not depend on strength (bldc.0.value). Shouldn't PWM curve look not like sine, but with kinks in the center, smth. like this: http://www.postech.ac.kr/ee/cmd/102_BLDC_pedal.htm ? My config hal file attached.

I'd say LinuxCNC is ready, but there are still issues with the platform in general: * There is currently no available I/O cape for the BeagleBone that is targeted at industrial control. Depending on how willing you are to wire up something from scratch, and how complicated you need your I/O protection, this could be a minor issue or a show stopper. Your mill also needs to be using step/dir control. * It depends on what you want to do for a display. The HDMI output on the 'Black has been causing nothing but problems for most folks, and will never run high resolutions like 1080p. If you are OK with oneof the 4 or 7 LCD capes, or are willing to by a specific HDMI monitor know to work with the 'Bone that should get you a display, but LinuxCNC has not been tested with a native display AFAIK. * Even if you do have a working display, you need to choose your interface wisely. I haven't been able to test with a native display, but the 'Bone has no 3D acceleration so I suspect Axis will always be a CPU hog and you'll need to use one of the lighter-weight interfaces. * Finally, you would very definitely be an early adopter. If you're OK with that, I'd say it's ready to try.

The drive was formatted EXT4. Linux could not fix the disk problems even after repeated tries. I plugged the drive into a Windows XP system and reformatted the disk expecting it to fail. It took a while to format but it did so cleanly and the Seagate diagnositic software said that all was good! So I imaged the original LinuxCNC system back onto the disk and it has been running fine in my office for over a week now. No flaky operation. So for whatever reason, the EXT4 file system became corrupted in such a way that the Linux system was unable to recover from it, even though the disk itself was still good.That is the first and hopefully the last time I see that problem!

But they are about done now, so I'll either trade up, or spend another 2G's for another set like those if I can find them. IMO, 60k+ miles on a set of tires that have never even been rotated, on a 4WD vehicle is phenomenally good, but they'll hydroplane in a downpour if I don't pay attention. Since the Toy is 4wd too, I'll probably trade up, for a long box topper regular cab 2wd.

But, there are no options, menus, etc to let you pick a drive format. So, I am installing again with whatever the default is, probably EXT4 -Tom -- Ummm...are you sure about that, Tom? Look carefully at the 'Prepare disk space' screen. Choice 3 is 'Specify partitions manually (advanced)'. Choosing it and clicking 'forward' gets you to a screen which let's you do most anything you want including picking partition format types.

Re: [Emc-users] Anyone seen a failure like this?
Another option is to get a copy of 10.04 and install that (that should give you the format option). Then download the LinuxCNC install script and do the install via the script via an internet connection. I think I did that the last time I did a fresh install and that worked fine.

I use TPEN6_6 firmware and bldc module in n mode. I am rotating it slowly (setp bldc.0.frequency 0.2). PWM outputs are true sinusoidal (checked on scope), but motion has some smooth (non-linear) parts and stop parts. BTW, I can't use bldc n6 mode, because I don't have where to connect A-high-value, A-low-value, .. because bldc component has A-value, .. pins only. When I use n mode, the motion is not smooth and it does not depend on strength (bldc.0.value). Shouldn't PWM curve look not like sine, but with kinks in the center, smth. like this: http://www.postech.ac.kr/ee/cmd/102_BLDC_pedal.htm ? My config hal file attached. Look at X axis. I would not expect very smooth operation in 'D' or step motor mode (no encoder feedback/PID), especially with IGBTs and their long switching times that neccessitate a large dead zone. Do you have the dead zone time set properly? I think the default is 5 Usec which is (deliberately) huge. (note: too small a dead time will be fatal to your IRAM) I would get feedback running before worrying a lot about smoothness. You definately do not want kinks in the top of the voltage waveform. if anything you may want a voltage step at the sine zero crossing to compensate for the dead zone (if the required dead zone is a significant portion of the total PWM period).

Re: [Emc-users] Anyone seen a failure like this?
So, it turns out this isn't a disk problem at all but a problem in our Rockhopper python interface that I have running by default on these machines. It is calling halcmd repeatedly and if Linuxcnc tries to launch during this time bad things happen. This is one of the items on the agenda at Wichita so hopefully we may have a resolution (or beginnings of) soon. Reinstalling everything from scratch is how I discovered it, so this was a helpful exercise.

[Emc-users] Hardware for sale - LinuxCNC
All, A couple of years ago I retrofitted a Cincinnati Milacron Cim-X milling center with EMC2. Due to an operator error this machine is no longer mechanically serviceable. I have the following for sale that was pulled from the machine: 1. Vital Systems Motenc-Lite Servo Controller and all daughter boards and cables. The daughter boards were used for the operator station only for pushbuttons and led bulbs for the pushbuttons. I also have the servo daughter board. 2. Automation Direct Sure Servo drives and servo motors (3KW). The motors have 2500 ppr encoders. The drives have an output of the position pulses for semi closed loop operation. That is how I used them and it worked great. You would need to purchase encoder and motor cables or roll your own. They have many different lengths. I do have the daughter boards and cables for the drives. All is in very good condition. Continuous duty on the motors are 15 nm and intermittent is about 46 nm. I also have the cable and tuning software for the drives. 3. I also have a Mesa Electronics 5i20 that I used for the general purpose I/O. 4. I have several opto 22 boards that were used for the GPIO. It's a pretty good mix so you tell me what you need and I will tell you if I have it. I have some other things lying around I hope to list. Make me offers for one or all. Thought I would give the people who know what this stuff is a chance at it before it hits auction. I need to buy some heavier stepper motors and drives for my router. The control was air conditioned in a climate controlled shop so all is pretty clean. You can message me off site at davidkeeton...@gmail.com.

[Emc-users] Hi All; I have two questions on Bridgeport's manual variable speed head.
1- Has anyone used a VFD to control the spindle speed via the G code? 2- Does anyone know a source for the lubriplate #107 recommended on the units service placard? Or an compatible alternative?
