Unable to set steps per mm #162

Closed scifunk909 closed 2 years ago

I've tried numerous equations to get the axis travel correct but nothing is working.

If your screw goes 2mm per revolution. You would divide the number of steps per rev by that. So 200 steps/2mm.... eg 100 steps/mm

What machine are you configuring - also, belt or screw?

if this helps...

You will need to change the following settings:

$100= (x, step/mm)
$101= (y, step/mm)
$102= (z, step/mm)

Type $$ in the command window and make note of the following micro step settings

$160 = (x, microsteps)
$161 = (y, microsteps)
$162 = (z, microsteps)

... and will depend on the stepper motor your using - for example: typical NEMA 17 motors are rated at 200 steps per revolution and you will need to do some math:

  1. Move each axis by rotating the the applicable stepper motor 1 revolution and measure the displacement in mm
  2. Divide 200 by the displacement in mm you determined in step 1
  3. Multiply and record the value from step 2 above with the applicable axis microstep value (this will be your $100, $101, and $102 value(s)

for example (x axis):
