Topic: Can't Stop PID Autotune

I've tried to Autotune my extruder PID by sending the M303 S200 command through Repetier, but how do I make it stop? The extruder is heating even though I tried hitting Disconnect and then Connect; Disconnect and close Repetier and relaunch; Disconnect, and unplug the Solidoodle (well that of course stops it heating). But when I plug it back in and hit Connect with Repetier, the Autotune just keeps going. I can't turn off the extruder!



Update: Ok, I think I was getting confused by the Scrolling numbers in the script window, the ones that say N3## M105 *##..these are just Repetier asking for temp readings right?

Re: Can't Stop PID Autotune

I could use  some guidance on this as well. I ran M303 S200 in RH and it did the same thing until I unplugged everything.

Re: Can't Stop PID Autotune

Define a set amount of Cycles with a C(X).  e.g. C10 would yield 10 cycles.  e.g. of full code M303 E-0 C10 S200 = Autotune, extuder 1, 10 Cycles, 200 C temp -- IMO don't set it for so many cycles that you bake filament in the hotend, other than that you should be g2g.  Enjoy.

Re: Can't Stop PID Autotune

Thanks. I had no clue about setting the PID except by cruising the forum. and then there was no complete syntax to use. This is a big help.

So you enter the last set of PID #s that the tuning spits out right?

Re: Can't Stop PID Autotune

A more firmware build/printer specific version of the G-Codes the link contained has been stored within the firmware as well, it is under the "Marlin" tab after you open the Marlin.pde file with the Aurduino v0.22 program.
