I have a new z-axis made from a TR18 leadscrew through a 1:16 gearbox, I've attached a Nema23 at first through the pololu driver and then through a 4A Pibot electronics stepper driver (TB6600) but it only functions up to around 5200 steps/unit. I'm using Marlin/Ramps1.3. Is there anyway of getting a higher step count (12800 would be great!) using my current hardware?
Thanks stephenrc, that kind of worked, I can get up to 12800 steps/mm now. For some reason auto home on z has now stopped working, it just drives straight through. Maybe I'll try to 1/8 step at 6400?
