I have an issue, out of the box after installing MMU2s on already functioning MK3S+.
Problem 1: First of all, idler does not align properly for feeding filament 1. The selector aligns correcty, and pulley turns in correct direction for loading filament. After manually repositioning idler, filament 1 will load to nozzle.
Problem 2: It appears that firmware does not sync the MMU pulley motor to the extruder motor.
2a. They turn at different speeds during load to nozzle.
2b. During 1st layer calibration they do not turn at the same time and sometimes even turn in opposite directions, leading to filament grinding and missed steps.
Is this lack of synchronization a "feature" I'm not understanding, a common bug, or an indicator of some other issue?
