Hi Luca

Could you check my maths to see if I've got this right

The steppers are 360/1.8 = 200 steps per rev

multiply by 16 as they are x 16 microstep = 3200 steps per rev

and the feedscrews are 2mm pitch so

3200/2 = 1600 steps per milllimeter

So i've got to set Z axis steps per mm in Marlin to 1600

Best Regards Mark

I have the MarlinKimbra Firmware but I do not feel is so much different...
... my parameters are : #define DEFAULT_AXIS_STEPS_PER_UNIT {78.74,78.74,400,95,625,625,625} so for Z=400

PS: my pitch is 2mm x 4, so 8mm!

Hi Luca

They are multi start screws so It is

1600/(2x2) = 400 steps per MM

Is that right

Best Regards Mark
