In this video, we will continue where we left on in the previous Scuplfun S9 limit switch install video (or similar diode laser). At this point, you should have limit switches installed and functioning properly as well as a macro programmed with the GRBL values needed for the limit switches to function properly. If not, follow our previous S9 limit switch install video before continuing with this guide. This video covers the flashing of clean GRBL so that changes made to the firmware can be saved permanently.
