Independent Z with Independent Sensors U steps/mm wrong
-
The ProMega config setup is a little unorthodox in my opinion. There have been a few other threads trying to sort through it in the recent past.
Have you seen this? https://promega.printm3d.com/documentation/software-firmware/adjust-homing-macros

Check that in config.g you have a M584 command that creates the U axis and also redefines the E drivers, earlier than your M350 and M906 commands. I'm using a smartphone so it's not easy for me to look at the config.g that you uploaded.

I think the problem is that the u axis isn't created until the homing files as it's missing from the m584 in the config.g

In that case the U motor will still be set up as an extruder, and the microstepping and motor current will be set as for the extruder. So if E microstepping is different from Z microstepping, that would explain the symptom

Yes, that's what I based my config on!

@phaedrux There's no reason to treat this like a Promega. I've gutted it, changed the Z drive system to dual lead screws, the rails, the carriage, the board, the bed...

Defining U in config.g before then combining worked for me. Thanks for the help!

Hi,
What is the reason for end stop switches on both z axes?

@fcwilt I believe it's used as an X axis leveling mechanism.
