Hello,
I’ve assembled the printer and could print a first part without any problem, and the quality of the part was really good.
But while i was printing my second part from SD card (my first print was also from SD card) I had a very concerning issue.
It seems that the printing head started overheating (but the temperature showed on the screen was never >210°C) and some smoke started to come out of the printing head, I’ve stopped the printing from the menu but it was already too late and the nozzle had melted the thread of the isolator guide and been pushed out on the printing bed (see pictures attached)
After dismounting the head (it was the right side one) i’ve tried with the second head to print a test file to see the behavior, this made also the same overheating process (while the temperature was also never more than 210°C on the LCD screen, and pushed out the second head nozzle as well).
I could see other cases like this on the support forum, with not really a clear explanation of what are the causes but it seems to be a bad interaction between temperature sensor and the heating control or a firmware issue (I did not update the firmware because the boot screen was showing version 1.1 from the first start of the printer)
I work in the same street in Asper so i could come and pick up the replacement parts if you prepare it today (that would be really helpful)
To fix the situation I think i would need for sure 2x HE1.75MM-IG as these parts are completely damaged ; and probably also 2x (HE1.75MM-NO035 / HE1.75MM-HB / CK8400-TK).
I guess 2 x SUBKIT 19 (HOTEND) would be the best option as the other parts could be damaged by the overheating (I could not slide the nozzle out of the Heater block even after unscrewing the locking screw and twisting it after that problem occured).
I’ve already sent pictures to Wim Dupré because I could not attach them to the ticket (filesize too big), so i did not issue a ticket yet.
Looking forward to your answer.
