Drafted size not equal to actual size

Controller is GRBL 1.0b

I tried changing the values in GRBL per the LB docs. After changing values the sizes were all over the place.

I just wanted to test a 1"x1" square.

The $100 and $101 values are how many steps to take per mm in the controller.

You say, “sizes were all over the place” - does that mean that they changed from one run to the next? Or were they just incorrect?

Meaning that instead of the 1x1 it was cutting 5x1.

Since it’s cutting 5 times too large on the X axis, take whatever the value is in $100 and divide it by 5.

For example, if the value is currently 400, you would change it to 80.
