Instead of re writing this all over, I’ll just link to my answer in another thread in how to change the settings.

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…

X-carve Grbl Default Settings - 500mm

I’ve been helping folks get their X-carve machines up and running. I’ve learned a lot. One of the things that I have noticed is that the grbl parameters seem to be inconsistent, especially when the Arduino has to be re-flashed. Long story short I wanted to find out exactly what the defaults should be. I took a new Arduino and used the EEPROM clear example program to clear the contents of the EEPROM (1024 locations), compiled the source code for Grbl 0.9j, downloaded to the Arduino, then ask fo…
