Run a stepper from 2 DM542 drive

[Clive S]

Well, if the DM542 drivers are already built into two different machines, my suggestion might be more work.

What you need to do it the way you described would be a 4p2t (4 poles, 2 throw) switch or relay.
This can switch the 4 wires of the stepper between 2 sources, but the switch has to be rated for the full current of the steppers.

You will have a good chance of blowing the drive if you switch if you switch it live

This is what I am afraid. Blowing a driver is not that bad (they are cheap), but the board of the laser is £1000. Open to any working solution. Thank you

Yes, i agree, thought about that only seconds after posting, but my post count is so low that every post has to be approved by a mod, so i couldnt edit it in time.
Sorry for giving bad advice :-)
