Waiting time after reaching print temp

Hey

Haven't found yet a place to tweak this. After reaching bed and hotend temperature Marlin always waits 60 sec. before it begins to print. I my oppinion it's a unnecessarily long time to stabilize the temp. I think 5-15 sec. would be enough.

In the config-file there seems to be no setting for this time. So where is it hiding? Has anyone an idea?

It isn't waiting for the temperature to stabilise per se, it is waiting for the heat to to spread up the PEEK insulator so that it expands to its maximum length. If it is too small you get inconsistent first layer thickness.

It is defined as TEMP_RESIDENCY_TIME 60 in configuration.h

Ok, I see. As I'm using the full metal e3d extruder it's propably safe to reduce the time.

Will do some tests.

Thanks again smiling smiley
