PWM or 0-10V output from breakout board

Hi all,

I am trying to control my spindle speed with either PWM or 0-10V output on my bob. I used stepper config wizard. But my spindle speed does not change. I checked voltage on the board and on the PWM output it is reading mvolts and does not change. And on the 0-10v output it is just outputting 9.97v all the time. Here is a link to the bob I am using and I am also using a KBPB-125 spindle controler. Any help is appreciated.

if the PWM output does not change, this suggests that there's a problem in your hal or ini file setup, possibly an
issue with pinout, polarity, and or scaling.

Can you post your hal and in files here?

Thanks for the reply. I will post them when I get home.

Thousand words:



and don't forget programm your inverter too

I'm not using a vfd.

Here are my hal and ini files.

It basically looks OK, do the step/dir outputs work?
That is is the parallel port /BOB working at all?

Can you measure the voltage at pin 1 of the parallel port when you set the spindle RPM to 500
and also verify that

pwmgen.0.value is 500
and
pwmgen.0.enable is true

When you do this
You can check these with halmeter or "watch"

yes my x and z axis' work as they should. i will go check the others you mentioned.
