Hello, After last work i didn't change anything, and now i am getting this error 1. When i check my old G code, and new G code i found that there is a diffrence, i don't know where this (') is coming from in my nwe Gcode. I am using Blackbox controller and Openbuilds Cam software.
Could you post the g-code file? I can't see the line of code grbl is objecting to in your screenshot. Alex. Sorry, must have been looking at the wrong screenshot, but I will leave this for an expert like @Peter Van Der Walt as I don't understand it either.
