Hi there!
I am using Mach3 to control 4 stepper motors. I am using appropriate power supply and drivers.
Everything is working good, except that motors are overheating when they are on but not in use (waiting for getting movement). Is there something that I should be to modify in Mach3 setup?
Any suggestion in this direction will be appreciated.
Thank You.
Eduardo.

If you were your motors would not overheat ;)
You have a problem with your motors, drivers and/or power supply selection. Mach can do nothing to cause your stepper to overheat.

According to sellers, these are the appropriate drivers.
These are the specs of this system:
- 4 motors NEMA 34: 1317 oz-in, 5.7 V and 3.0 A/phase
- 4 drivers: SD-2H086MB
Suitable for-2-phase and 4-phase motors
Output current up to 5.86A
Dip switch current setting 8different values
Optically isolated input signals
Pulse frequency up to 200KHz
Supply voltage up to +80VDC
- a breakout board
- Power Supply: 220W, 24VDC
Can you advise me on this?
Thank You again.

OK, let's start back at the begginning -
1) What current level do you have teh drivers set to?
2) Define what you mean by 'overheating'. What temp are the motors gettign to?
