I’d check your grbl settings. You should type $$ in the console line to see them. To adjust them you have to find the ratio of what you want to what you get and multiply that resultant number by the grbl setting for the number that is saved. The setting most impacted might be $100, $101, and $102

If you’re using OpenBuilds Control as the gcode sender, there is also a walkthough on that calibration (specifically for the workbee) with photos and blanks to enter your data, it does all the math for you… :+1:

Thanks Seth, I’ll try and find it, appreciate the help

In openbuilds control its under the wizard button at the main screen :+1:
I use a straight edge across the top and a mechanical pencil and measure with calipers to get it even more accurate…
