Weird Steps/mm Calibration

Just starting to setup GRBL 0.9J on my Arduino and am a little confused.

The default setting for $100, $101 & $102 are all showing as 250.000 steps/mm, however when watching a calibration video on Youtube, the GRBL settings are showing as $100 = 40.000, $101 = 40.000 & $102 = 188.947 not sure why mine are so different.

I am using Nema 23s for X, Y & Z. Hoping someone can explain the difference.

Most likely the version of grbl that’s installed in your Arduino is not from the Inventables fork. Use this to re-flash the Arduino.

Thanks Larry … thought there was a simple answer
