FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.05 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2019-12-13b1
the print setting was at 60mm/s, 245 degrees hotend and 80 degrees bed heating
the printer has a 60w ceramic cartridge (i had some issue of temperature stability before tuning hotend heating because it became hot too fast and it exceed the 15 degree over temp during warming, now seem to be fixed)
pt100 platinum temperature sensor
200w 230v heatbed
at the moment i feedback two errors about temp at the startup after autotune of heatbed and extruder
Warning: Heater 0 appears to be over-powered. if left on at full power, its temperature is predicted to reach 320C
Warning: Heater 1 appears to be over-powered. if left on at full power, its temperature is predicted to reach 1326C
