Hello there,
I've built myself a tool changer with 3 lead screws on Z. So far pretty much anything is working perfectly but i have a problem with a shift in Z.
The alignment of lead screws and linear rails on Z is almost perfect so they shouldn't be the problem. Ive narrowed down the problem to software bc i noticed that sometimes when i move z after homing x and y also move- even tho they're not supposed to.
Im using a Duet 3 6HC in standalone mode alongside an expansion 3HC, both are updated to the newest non Beta version.
Please excuse my crude config.g file, its still a prototype and its my first Printer.
And please excuse my english, its not my first language & thank u in advance!!!
