Klipper dual z alignment. 2° (you can feel it easily) will fix it.

You will need to increase the current for the z axis, but not double it. I havent even considered splitting the output of a single controller because that just sounds like disaster from the very beginning with all the potential timing and out-of-sync issues. You will have to play with adjustments until it works I then added the The dual Z 42-34 stepper motors with T8x8 lead screws. I also tried a full manual level then print without the Z tilt (always keeping the steppers engaged between level an print) and it printed perfect. 1. io. There are many SKR boards and while some boards like the guy mentioned above have Z ports with individual drivers, the Mini E3 does not. Key Features: Visual Alignment Monitoring: Effortlessly observe the synchronization of the dual Z-axes. Use 1-2 perimeters, or even better the smooth vase mode with 1-2 mm base. 2° (you can feel it easily) will fix it. The Coupler of Stepper_Z (left) will actually split and undo itself, with the Lead-Screw moving up several mm.
