Qidi X-Smart Not Reading Hotend Thermocouple Temperature - Please Help
Posted: July 4th, 2022, 11:37 pm
Hello,
I have a Qidi X-Smart printer. It is not reading the temperature of the thermocouple on the hotend, or, rather, the software shows a temperature of 600+ degrees (fahrenheit) whether the thermocouple is connected or not.
Remedies I have tried so far:
1) Replace the theremocouple (first with a generic one from Amazon, then with an OEM replacement from Qidi). Result: No change
2) Replace the breakout PCB board to which the thermocouple connects. Result: No change
3) Re-seat the thermocouple in the hot end. Result: No change
4) Replace the ribbon cable that connects the breakout PCB to the main board. Result: No change
5) Software "factory reset". Result: No change
Prior to experiencing this problem I had a blockage of filament in the hot end. Once I remedied that, the current (thermocouple) problem started.
I took the printer to the local 3d printer repair shop. After a month they hadn't come up with a solution or even a diagnosis, so I took the printer back and tried replacing the parts listed above. I would think if the problem was something obvious, they would have figured it out quickly.
Any help, insight or hypothesis to be tested will be much appreciated.
All the best.
