Gt2650 revB intermittent extruder temp regulation

Post by Stern5871 » Sat Dec 02, 2017 5:16 am

I have a MeCreator2 that seems to regulate extruder temperature when printing only when cooling down to reach its coded setpoint. On manual, i can select temperatures and extruder heats and stabilizes to that setpoint. When printing from gcode, setpoint temperatures are correctly displayed on LCD, but extruder will continously heat until maxtemp error. If i preheat the extruder above the gcode setpoint and print, the job begins when the extruder cools to the setpoint and progresses normally.
Troubleshhoting steps so far:
I have reflashed the firmware
Run print from SD card and via USB
Continuity checks from head to GT2560
Changed extrduer heater unit
Thanks for any advice!

Can you try to restore the factory settings, and then see if the problem is solved.

For those following this temp regulation issue:
I re-installed the firmware twice.
William sent gcode to print a box, which exhibited the same issues... runaway extruder heating temperature, yet printing ok when it cooled to the programmed (gcode) temperature.

Here's a video of this:
