Code: Select all

`#define _AXIS_STEP_PER_UNIT {80, 80,1600 ,700}`

hi guys,i use ramps1.4 for my first DLP 3Dprint .my Z axis moves 4mm every 6400 steps.

so,The Z-axis is set to 1600,right or wrong?what's the true number ? thanks. i have no XY axis.

hi.. currently I'm using nema 17 stepper motor (1.8 degree, 200 steps/rev, 1/16 stepping, 2mm pitch) Hiwin KK50 linear actuator, here it is http://www.hiwin.com/pdf/single_axis_robots.pdf

will you please tell me how to calculate steps/mm ? thanks in advance.

I have the same configuration/problem i'm using trial and error procedure but is too much timespending and unproductive, your help is appreciated.
