Error Heater_ID: 0 with cura 4.3

What is the problem?
When i use cura 4.3 and upload in octoprint, the print start and after 1 layer it stop.

What did you already try to solve it?
I have print same file 5 times and each time the error was at same place of print.
when i use cura 3.6, i don't have the error

Logs (octoprint.log, serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)

why with same 3d model, in cura 3.6 its work and cura 4.3 doesn't work?
i dont understand

Already considered a fault with the slicer?
You may compare the produced gcode files of both.

I have compare 2 files but its not same syntax to gcode

The syntax is the same - the values are different.
Of more interest is the header, the very beginning of the file where the settings are made.
It would be quite handy if the gcode files are from the same model at the same/middle position.

But it is the same 3d model...
3.6.gcode (712.1 KB) 4.3.gcode (706.2 KB)

So there are differences.
I found this in the Cura 4.3 gcode file (not in the 3.6 file):

M140 S60
M106 S255

M106 S255 powers the part cooling fan up to the maximum. And depending of the position of the print area, it can cool the bed or the hotend so much down, that the thermal runaway protection is triggered.
If it is the bed, you may reposition the object, lower the the fan speed or make a slight correction to the firmware (the value the firmware recognizes a variation as thermal runaway issue.
If it is the hotend, the part cooling fan nozzle should be repositioned or redesigned.


@Ewald_Ikemann I didn't recognize you at first because of your new profile picture :smiley:
