Hello again, I have a new power supply on its way. I have given myself a couple issues which I'm sure my good knowledgeable friends on here could help me with.

1- The new power supply doesn't have a connection that I know of to connect to the spindle speed potentiometer on the outside of the power / driver control box

2- Has anyone any ideas on how to connect the spindle speed potentiometer into the power / driver control box?

3- Is it possible to ( control the spindle speed just by using Mach3 commands) If so how?

Once again many thanks in anticipation of your solutions.

Best regards

To control your spindle the power supply, needs a pot control which has a 0-10v PWM output to control your spindle speed, a regular power supply will not do this, the one your machine has is a special and I posted a similar one that you would need for your spindle.
