Topic: Extruder heater shutting off after every print. Why?

Using Repetier and Slic3r. I think I must have set an option somewhere to tell it to do this since it does it so infallibly, but where? I'd rather it stayed on.

Re: Extruder heater shutting off after every print. Why?

Okay, thanks. Not being a G Coder, I assume you mean there is a M104 SO in the GCode. So, how to I make it stop doing that? Also, could you recommend a good primer on GCode? Thanks, Ian.

Re: Extruder heater shutting off after every print. Why?

Personally, I like disabling the print head between jobs because it helps avoid having filament sitting hot in there. Seems to be the leading cause of clogs.

+1 on that...I never leave my extruder hot without running a print; and it heats up so fast, I find it a non-issue.  BTW, I've haven't had a clog in over a year.
