Hi, I'm looking for some advice on a highly customized 3D printer setup!
I have a home-made printer using a RUMBA board with Marlin and stepper motors that I control via Printrun's Pronterface using my laptop. It has dual Z-axes configured so that each of my two Z-axes move together (both are plugged into separate ports with their own TMC drivers). I am aware of all the auto-leveling features, but none of them seem to allow me to manually control each axis independently for a brief moment (ie by sending the G1 command). I move them together 95% of the time under a single axis name, "Z", but 5% of the time I'd like to decouple them to move independently. I end up just manually twisting the lead screw with my hand, but it would be nice to be able to control them independently by sending G-code commands. I haven't found a workaround to do this, so any guidance would be greatly appreciated!
