Hello RepRapers,
I am testing latest released Marlin FW 1.0.2 in my 3D printer. My printer is monitored by OctoPrint, but I always print from SD card. Today, I spotted strange behaviour of my nozzle temperature - when there was a lot of small moves (high resolution cirle, etc.) the temperature felt down from 230°C to 170°C on OctoPrint graph. There was "Cold extrusion prevented" in serial log too. After this anomally, nozzle heated up again. I spotted this behaviour first time, NTC thermistor is OK. Other prints temperature regulation is rock-stable (+/- 0.5°C).
I think that the processor have no more time to handle temperature regulation when there is high GCODE command flow.
Do anybody have the same issue? :)
Regards!
Smart - O.C.
