hello everybody
i am trying to make a delta 3d printer out of recycled parts
the printer uses 200 steps per revolution steppers at 1/2 step mode with xl belts (5mm pitch size) with 10 teeth pulleys
so the steps per mm for this setup will be 2*200=400 steps per revolution
and 5*10 =50 mm per revolution
this mean the steps per mm will be 400 /50 =8 steps per mm
so the resolution for each axis will be 0.125 mm and this is the minimum distance each axis can move
the problem is that i can't let my printer move 0.2 mm i am trying to use the 0.1 key in the host but what's happening is that i only can move 0.7 mm as minimum distance and that will happen only if i pressed the 0.1 button 7 times
so any body can tell me what is the problem please
sorry for my english
