Z-level adjustment

Hello everyone,

For a project I am working on, it is extremely important that the distance between my nozzle and the substrate I am printing on remains permanently the same (µm resolution sometimes). Live adjustments are not easy to implement within the standard set-up. I therefore wonder if I could integrate the stepper motors in addition to the regular control in a control circuit where I measure the distance between nozzle and substrate with a laser and make live adjustments by controlling these motors. All this without affecting the standard set-up.
