XL failure - unable to solve :(
Interesting update: this appears only when we use menu "preheat" or start the print. When we use "Control" icon and set heatbed and nozzle temperatures separately (but heating is running at the same time) - this does not happen. But it doesnt fix our problem that we cant actually print.
Updated: 6.4.1 FW does still the same error and as soon as we start heating the bed - fail. When we heat just extruder - no issues, no faults.
So - our XL stopped heating bed. As soon as we start heating bed - error 17202 (or sometimes when print sheet is placed on tiles we also get 17303 error).
Error appears roughly 10 seconds after start of heating the heatbed. Nozzle heating absolutely fine, no errors, extrusion normal (we have 5 head XL). Thats why we dont think it has anything to do with Extruder but heatbed (and mentioned 17303 error sometimes).
FW 6.2.5 + 8912, BL 2.4.1
What all I did:
Changed modular bed board for a new one - nothing changed.
Modular board is now "hanging" in the air to prevent any contact with the aluminium heatbed holder (i thought there might have been somewhere some short circuit). Our board already has that metal spacer sheet (our XL was manufactured in 2024).
I ordered several heat tiles (not all 16) and tried replacing each of "old" with the completely new one - nothing changed
I changed all 8 cables leading from modular board to tiles on one side and then on other - nothing changed
I changed the cable leading from modular board towards main board in the back - nothing changed.
I tried to move and wiggle with the powercables leading from PSU to modular board - nothing happens doesnt seem to be "broken cable"
the last thing - we also ordered one new power supply - but I am not sure if I want to try replacing it and seeing error again :(
So - anyone ever had similar issue? We need that machine running, as our C1Ls and HT90 are fully occupied all the time :(
