i recently build a dremel 4000 3 axis cnc with arduino uno and drv8825 driver and nema 17 stepper motor its works fine but i wanted to attach a pen holder to z axis with a SG90 servo to lift pen up and down ... i searched on google but didn't find anything related to uno running openbuild somebody please guide thank you
you do know that you get Z control OR servo control, but not both at the same tiome, so to swap between them you have to reflash.
i get it..... z axis and servo both are diff i wanted to repalce z axis and put a servo to make it work as pen plotter
