Hello, first time I'm trying to use external drivers with a grbl (MKS DLC32 Max) controller and I'm having no luck. Can't seem to get any torque to the motors. I'm using a 15 amp 24vdc PS that powers the controller and the X axis, and 3 5amp 24v for the other axes. controller to driver: S -- PUL+ D -- DIR+ E -- EN+ G -- to all 3 grounds for the above. All wiring seems to check out, measuring .9 ohms across each coil in all motors. Measured at the controller end. I have 18awg shielded for the motors. Using DM542T drivers all set to 5v. The Z axis is the only one working well. The others don't have enough torque to move the gantry or X axis and no holding torque at all even with $1 set to 255. What am I missing? Find it hard to believe all the drivers are bad so it must be something I did wrong.
Why not just use the one 15amp. Have you tried that? Also, have you contacted Makerbase Customer Service? They may be able to help. It may be a known issue.
I have tried only the 15 amp first. Didn't work so my first thought was it wasn't providing enough power (4amps to each motor plus the controller) so I added the other PS's. No change. The drivers I'm using are active low for enabled so the second post probably doesn't apply. I ordered different drivers to try and waiting for delivery.
