Run 2 stepper motors in parallell off the single output on the Cohesion Controller Board

Machine: Chinese machine with chinese controller board

Board: Laserboard
Firmware: “I have a new board and I’m using whatever it came with”

Can I run 2 stepper motors off the one output on the controller board - I have 2 steppers on the Y transom - can I split the output to drive both of them

Hi Dennis,

Yes and no, it depends on how much current each of your stepper motor uses. If the combined current of both motors exceed 1.2 amp RMS it will blow the output driver.

There is a way around this, check out this post on how to use two motors on one axis: I need to slave the A drive to my duel X motors How?
