I’m having a problem and I can’t figure it out. Side to side it burns to scale perfect. But if I have a 12" from top to bottom canvas it will try to burn 14" to 15" instead of the 12". Is there a setting for that? Maybe something I don’t know about. I hope I explanned it right.
For GRBL firmware settings $100, $101, $102 correlate to steps/mm for X, Y, Z respectively. The specific number is dependent on the stepper motor itself and any gearing off of the stepper.
You can check these values in either Edit->Machine Settings or by hitting $$ in the Console window.
These are typically pre-configured for commercial solutions but you’ll need to tweak these for custom solutions or if you’ve modified your setup in some way.
You can use the Calibrate Axis function under Edit->Machine Settings if you want to tune these.

It kind of points to the Y axes behaving or configured different.
Check that $2 has the same ‘step pin’ settings. There are 4 of them in the ‘Edit → Machine Settings → Outputs Setup’. Mine are all set to false or zero. This way is quick… the other way is…
Setting it via the console, you will have to figure the bit patterns… I would think they should be the same with the same motors.
.
Make sure when you are in Machine settings, that you save a current ‘factory fresh’ copy of your configuration via the ‘save’ button… before you change anything…
