Thanks m_c,


I am currently set to 16 on the drivers and it runs fine but will change this to 8 and see how it goes.

The X and Y motors are directly connected but the Z has a toothed belt, It seems to be a 1:1 ration so should be fine. I think i need to measure the pitch of the screws then I can calculate the steps as you described.

The sensors are the 3 wire type and are 10-36vdc so I will get one hooked up to some power and see what the output wire does when it reaches home.
