The start of this board is shown above. 0-beta planner. By default, if you have homing enabled and power-up the Arduino, Grbl enters the alarm state, because it does not know its position. You don't have to calibrate the controller unless you want to customize the range of motion of the axes. I designed the project to be indicative of lost steps and calibration errors under load, but the default values provided by Easel usually need to be tweaked slightly for the individual machine. Source code. Your best companion in cnc machine shop. CNC Plans and hardware option includes the large plans set, motion electronincs (motors, drivers, power supplies, and controller/interface), hardware to fasten all of the components together, a water cooled spindle with VFD and all of the necessary mechanical components (rails, bearing blocks, lead screws, bearings, etc. While I was at the Makerfaire in San Mateo, I realised during the conversion of Nick's K40 machine that I hadn't written instructions on engraving calibration. configure GRBL for coreXY plotters, create a g-code calibration file using Inkscape 0.
