Not sure I’m posting this properly, in the right thread etc, here goes:

I bought a used PM25 originally converted to cnc by Procut. Previous owner disconnected spindle control cuz he couldn’t get it to work. I am trying to fix it. I have the procut spindle control board like the one on their website, Ethernet to procut industrial control board, and Ethernet smooth stepper. Procut has not responded to my questions. I finally got the spindle to turn on but the display rpm on the machine does not match any of the 3 displays on the Mach3 screen. Can someone please walk me through the dang settings in Mach3??

I little bit more information might help give you some better answers.

1. When you say you get the spindle to turn on but the RPM does not match, are you able to control the speed through Mach 3 at all or is it just power on and power off?

2. Which motor and control board are on the PM-25?

3. Is the readout on the machine correct and its just that Mach 3 is showing a different speed?

Thanks for the reply.

1. I can control the spindle through Mach but only by selecting speeds higher than 700 and my using the spindle over ride slider, then it jumps to max rpm on the machine rpm readout

2. The stock motor is a bldc 700w 1hp and the spindle control board is “procutcnc”

3. I assume the machine is showing the correct spindle rpm...Mach is not matching that at all
