GRBL settings (calibrating step/mm)

1

I have searched and can’t find the topic anywhere, I know I have seen it. Help please.

There is a website that has the grbl X,Y,Z settings calculator. Does anyone have that? It helps with stepper travel. You enter the travel required and the actual travel, then the site gives you a value to enter into the $ value.

Thanks.

To recalculate step/mm value simply use this formulae:

(Current step/mm value) * (Jog command distance) / (Actual travel distance)

Say step value is 100 and you command a 200mm jog but only measure 170mm of travel:

100 * 200 / 170 = 117.64
