Carving is bigger

[MartinW.Mcclary]

You need to calibrate the grbl settings. This is the steps per mm found in $100, $101, and $102.

I would ask you to read this thread as I answered it there and how to make the changes. I had to do it myself to achieve better accuracy.

Calibrating my X-carve 1000

The calibrations for accuracy are basically zeroing in on the steps per mm for the axes. Your machine has to be mechanically adjusted first, which you have done. It’s just a ratio of two numbers. What you want/ what you get. You multiply that by the number in the $100 and $101 for the x and y axis. For instance if you want x to go 10mm and it goes only 9mm, then 10 / 9=1.111 and you’d multiply that by the number you now have set for $100. It requires an accurate measuring device and yo…
