Z Axis Steps/mm

Post by macfreak84 » Tue Sep 14, 2021 11:59 am

Hi,

I've made lots of changes to the firmware and somewhere along the way I played with DEFAULT_AXIS_STEPS_PER_UNIT in Configuration.h. My understanding is that these values can be calculated from the number of teeth on the drive gears of each motor, but I have no idea how many teeth are on the gears that came with the machine. I am currently using:

#define DEFAULT_AXIS_STEPS_PER_UNIT { 162, 162, 814.6, 200 }

All of the values have been multiplied by 32 instead of 16 because I am using DRV8825 drivers with 1/32 microstepping.

What should I use for these values on a stock Geetech A10 (with DRV8825 drivers)?

Thanks!
Eliot
