Pause after bed reaches target temp

I just added a 4mm aluminum sheet to my printbed. I'd like to extend the time the printer sits at target bed temperature before it turns on the hotend. Where in my firmware can I change this?

Hey Steve,
two ways to do this. Look for the following code in configuration.h

#define TEMP_RESIDENCY_TIME 10 // (seconds)
#define TEMP_HYSTERESIS 3 // (degC) range of +/- temperatures considered "close" to the target one
#define TEMP_WINDOW 1 // (degC) Window around target to start the residency timer x degC early.

Change the residency value to the length of time you want. Though if your bed wobbles a bit in temp you might
need to increase temp_window. This patch of code affects how long M109 waits before returning.

Second is somewhere in Slic3r, there is a pause addin to the gcode. Thats all I know, I saw it in passing the
other day.

Oh, have you rerun Autotune with the Al bed in place?


Hope this,
Andrew

Hey thanks! Just found "G4 PXXXX" where X is milliseconds to pause. I'll toss this into my gcode when I print.
