I'm working dual toolhead setup. T0 regular FDM extruder and T1 a syringe-based paste extruder. With any change, let's say a new needle, the needle will be off every time.
Is there a way to measure and set the needle-offset by passing it through a series of different opto-endstops, let say X' Y' and Z'?
This is with the intention of using a macro after homing T0 to set the T1 offset automatically.
