Post processing spindle issue

[groucho]

Could someone give me some guidance on how to alter fusion 360 G-code to work with my PRS standard shopbot. My spindle is not turning on. I thought I read a post on this forum previously but I can't seem to find it now. If memory serves I'm suppose to put a "SO,1,1" near the beginning of the code and then a "SO,1,0" at the end. Can someone confirm the validity of this and maybe show me an example of exactly where to insert this stuff.

Any help is greatly appreciated.
