General Mach Discussion / When is PID too high??

« on: January 04, 2010, 03:42:21 PM »

dspMC / Mach3 conversion on a V2XT. Using Axis Works software. Tuning the axis motors (servo) and the machine wouldnt do the same thing twice. Started out at "P" 4000 and "D" an times 25 factor which is 100000. Motors run very smooth but going back to zero is all over the place. All ways and screws are in very good condition. Lube pump is working. I have the P now at 25000 and the D times 25. Seems alot more accurate within 2 or 3 counts. Scale has always been 100. What do I do, just keep going? Or am I way out of typical range as it is. Stock SEM motors and 250 encoders. Anything less than 2500 P wont move the motors. Your thoughts??

Also, motors have a tach but I have the amps in torque mode right now. Still learning

Tried it and the macro does work in code but does not work when clicking spindle start. There must be an easy way to do this. I thought macropump would be the way to go but back to my original question I just dont know how to script it.

I guess I thought the only time those macros came into play was with running a program. Are you saying that when I mouse click the spindle icon it is reading the "M3" macro? How does the software know to "M5" when clicked again?

Going to try to do this with a macropump.

Many hours of reading, searching forums, studying manuals.... my Bridgeport conversion is almost there. Seems the "macropump" file is the way to go for a couple of issues I have. I have an air spindle brake that must be activated before the spindle turns on. I tried this with a brain but the spindle would start at mach3 loading. Other than that it worked but there are a few other (if this,then do this) issues that I cant seem to accomplish with the brain editor. Wonder if someone could just show me what the macropump format would look like and I can work on it from there.

Spindle M3 is pin 1 and M4 is pin 2 outputs.
Air brake is pin 5 output.
I also have a low air input on pin 11 and a spindle overload on pin 12. I need the spindle to be disabled if there is a low air signal (if I forgot to turn the compressor on or if an air line should break while the spindle is running) both before the spindle is activated and while running. I don't want an EStop, just for the spindle to be disabled. Air brake also needs to be disabled after "spindle off". (disable engages the brake)

macropump might be something like:

check for low air input and disable spindle (wont start)
if low air stop spindle and disable brake
spindle off disable brake output
same with spindle overload

Thanks in advance, RonO

Brains Development / Spindle off

« on: December 31, 2009, 03:33:53 PM »

Have a spindle off button on my bridgeport. Made a brain using its input (input 31) and terminates to "button press" "spindle off". It works fine but it also turns the spindle on which I don't want. Tried a few variations in the brain commands but on/off is as good as I can achieve.  Is there another way?
Thanks, RonO
