Thanks for this last piece of golden wisdom. Since I'm pretty new to G-Code maybe you could clarify for me what you mean by "the end". Is this insertion of SO,1,0 before or after the end statement. Fusion output apretty involved list of code and I have a couple "end" statements and don't want to get this wrong. I assume this precedes the "end" statement but I'm not sure which. I did manage to get the fusion 360 code working on the shopbot but I've subsequently run into some technical difficulties. I'm not sure if my confusion about the insertion of this final statement is partly at fault . Any help is greatly appreciated.
