smoothie with openpnp

[inte...@gmail.com]

I’m running into a strange issue with a stepper motor on an Smoothie/MicroSMT board running OpenPnP 2.4.

On power-up, the stepper holds torque properly. However, as soon as I issue any jog command or G-code, the motor disengages and spins freely. If I follow up with an M112 (Emergency Stop), it immediately re-engages and holds torque again. Essentially, any motion or control command causes the motor to drop hold current.

For context, I have servos running on two other channels on the same board and they work fine. Is there a specific Smoothie or OpenPnP configuration setting I might be missing for steppers? Has anyone seen this issue?

I connected a 42 57 manual stepper driver to check motor and  wiring and it worked fine.  

Config file attached.

Thanks in advance

It sounds like you have enable logic that is inverted? So when the stepper should be disabled it is enabled, and when it should be enabled it is disabled?

Yes you are right, working now.  We tried it before but it may have not been saved but on trying again it worked. Appreciate it.
