Kenny is a great guy to deal with and I have had the pleasure of visiting him since he is only a few hours from here. Like many of the people on the forums he gives freely of their time and knowledge.

dspMC/IP Motion Controller / Re: DSPMC Mach3 integration issues

« on: February 14, 2013, 06:21:53 PM »

Hi Rich,
Setting the PID is really trial and error.
Here is what I did on mine. I will assume inch measurements. I started with everything at 0. In the test motion section I put in short moves of .5 to 1 inch. Try a velocity of 100 and an accel of 10 to get started. Then I started putting in values for P until I got motion and had overshoot. P wound up being ~9000. Then I started adding D until it smoothed out and looked good on the graph. I then added a little I. Something on the order of 1 to 5 should do it. Too much I will make it take a long time to settle. I set a max error I of 10. A dead band of 3 -10 helps stop a lot of the dither when the machine is sitting idle. The deadband is in encoder counts so if you have a decent resolution encoder it will not even be noticeable in daily use. Once this all looked good I then add velocity feed forward which helps response. then I start adding in low pass filter. Low pass filter is adjusted in increments of 1 or 2. when you hit it just right it makes the motors nice and quiet when moving. Following error should be setat 1K to 2K to start. you can then tune it tighter depending on your machine requirements.

HTH.

Hi Rich,
I just replaced my computer on my DSPMC powered mill so it is still fresh in my memory. Did you go into ports and pins and enable the axis that you want to use under motor outputs?
Then go into the plugin config page and set the PID tuning? I found that starting from P5000 and everything else 0 you you can tune from there. If you can,t get motion on the plugin config page you won' get it in Mach3.

If any of these suggestions don't work, come back and ask again. either Rufi or myself should be able to get you going.

Nice work,
I especially like the way that you counterbalanced the Z by putting the motor onto the backside of the machine.

Machscreen Screen Designer / Re: Klaus, it hasn't been said for a while, but, THANK YOU for Mach Screen!!

« on: January 26, 2013, 07:24:27 AM »

+1 on the thank you.
I don't do too much with screens but when I need to make a quick tweak it is nice and easy to do with Machscreen.

Galil / Re: Remote jog pendant again

« on: January 25, 2013, 06:02:52 PM »

If you want a jog pendant I use a game pad from logitec and map the buttong using Keygrabber. Works like a charm. The hardest part is finding out the keyboard shorcuts. The easiest way I found was to open the standard screen set in Machscreen and look at what Mah3 is using to make things happen.

It is similar to this one

http://www.logitech.com/en-us/product/gamepad-f310?crid=713

It has 16 buttons and you can have up to 4 pages of buttons via keygrabber.
