Microsteps, Pitch, Lead and DEFAULT_AXIS_STEP_PER_UNIT in firmware on Z-axis
Hi! I was just wondering if someone can help me with the correct value for the z-axis configuration in the Buddy Firmware. I do have a 8mm pitch spindle on two of my mini-clones. I would like to try to use these spindles, so I took a look into the Buddy Firmware and found in the Configuration_MINI.h the values:
#define DEFAULT_AXIS_STEPS_PER_UNIT \
{ 100, 100, 400, 325 } //E0 280 295
When I turn the spindle 360° on my original Mini it looks like the original has 4mm pitch. If so, how does it come to the value 400? I believe the stepper has 1,8°, so 200 steps per 360° which would be 50 steps for 1mm. Is the default 400 because the mini does use 1/8uStep so I just can drop the value for 8mm pitch spindle to 200?
