I apologize upfront for being new at this and being lost. I have a chinese 3018 CNC unit with a Woodpecker CNC control board that has GRBL 1.1h loaded. I have wiped the eeprom and reloaded the GRBL.
What I can’t seem to figure out is how to set the $2, $3, $23 in the GRBL to get this unit to home and start at a bed corner that equals X 0, Y 0 - then moves in positive direction (cartesian scale) that matches the bed grid.
I may have this wrong but what I think I am looking for is the ability to turn the unit on, hit the home button, then when the home cycle is complete get the position and have it read X=0, Y-0. Then if I move off the of the home corner onto the bed have the X and Y coordinates move in a positive direction.
Right now if I move the lase the X and Y go into negative numbers and the positive quadrant does not align with the bed grid.
Any advise would be welcomed.
