Question: I just hooked up my spindle (OpenBuilds Ox with TinyG v8, latest firmware) and I can speed up the spindle with M3 S10000 and slow it down with M3 S0, but it never stops. Even M5 command leaves it running, the same as M3 S0. Is this the expected behavior? It seems like I should be able to completely stop it, not just go from slow to fast.
In CP Serial Console command line, set $p1pof=0.0 (hint, $p1pof=0 does not work). then send Gcode “M05”. More info here https://dl.dropboxusercontent.com/u/50261731/Spindle%20Test%201.doc
@cmcgrath5035 Bingo! That was it. I just sent the command, “$p1pof=0.0” (sans quotes) and now it shuts off completely when I send the M5 command. Thanks!!
