Machine not returning to work zero

[NeilFerreri1]

@PatrickDunne How’d you carve a 3" circle with an X-axis that’s off by a factor of 10?

Anyway, to calibrate steps/mm (number of steps the motor takes to create 1mm of travel):

My bed is too tiny?

In Easel, go to the machine inspector and type $$. That will give you your grbl settings. The X axis steps per mm is stored in the $100 parameter. Y is $101 and Z is $102 Lets say your setting is currently 250.000, you try to jog 50mm and it actually moves 12mm. Expected/actual*current steps per mm = your new steps per mm. So, 50/12 = 4.1667. That times 250.000 = 1041.667. You’d enter $100 = 1041.667. Repeat the tests until you get it dialed in. I’d jog as far as you can, and make sure you …
