I feel like its in the gcode... this is the last part of the start sequence and the beginning of the print: M104 T0 S(210, 0) G92 E-7.0 G1 E0 F45 ;purge nozzle G1 E-5.1 F1500 G1 X60 Z0.01 F5000 ; move away from the prime poop G1 X20 F9000 M400 ;finish all moves G92 E0 ;end of startup sequence M141 S28 G92 E0 G92 E0 G1 F1500 E-5.1 ;LAYER_COUNT:1 ;LAYER:0 M107 M104 T1 S100 M204 S250 M205 X10 Y10 G0 F7200 X14.5 Y46.543 Z0.27 ;TYPE:SKIRT I've edited the file manually and added M104 T0 S210 after the M104 T1 S100 part, i'll let you know it this fixes it... Edit: looks like it works, it's not on the correct line i think... Temperature of T0 goes down at the beginning, so i might add a M109 T0 in there to wait for the correct temperature. But weird Cura doesn't add this itself... did I mess something up with the resources files? Or should i add any information in this settings menu? (see attached image)

Thanks for the quick reply! Just printed again and checked. In the standard menu i can select the nozzles and see the temps: Nozzle1: temperature going down / 0 [Looks like the gcode/firmware is really cooling it down to zero) Nozzle2: around 160 / 200 [Temperature in standbye] I'm not sure where to find the last firmware verison? I downloaded the github one, V19.03 [Dated five years ago..]

Just a quick update, Chose the normal UM2 profile in Cura to print with a single extruder, worked flawlessly! Chose the Mark2 UM2 profile in Cura to print the callibration print: - Everything heats up fine (to 210 degrees, which i stated in Cura) - First to test lines get printed fine, then the 1st extruder starts the print, and the nozzle temp just stumbles slowly down... Is the printer not able to keep both nozzles at the correct temperature (Power wise?) read most of the complete topic, but i'm unable to find a solution... if someone has any idea what I'm doing wrong....

Just completed my UM2 Mark2 build. Ordered the PCB from aliexpress, just replaced the magnets to some better ones and wanted to print my first (single extruder) PCB case with the new firmware. The printer heats up just fine, makes a little line with extruder 2 (which is strange, didn't select extruder 2 in the cura print file...) Extruder 1 follows the test line and the little poop. After that, both extruders cool down to standbye temperatures, so i'm not able to print anything... Am I missing some setting i needed to change?? I do get some temperature sensor errors, but after heating up the extruder with a heat blower, everything runs normally... (Cura 5.6 with the Mark2 Profile and modded nozzle files)
