*P1S nozzle and bed not heating. The screen shows 0 Celsius for nozzle and 0 celsus for bed. Checked all the wiring connections, Looks OK. Is there a fuse for the heating system.
The connections to the nozzle is ok
under the bed the wiring is well connected
Disconnected the printer from the main cable many times and restarted. But the problem persistes
No error code on display
P1S printer with less than 200 hrs printing
If the reading is 0 C that sounds like a sensor or circuit board issue to me (they should at least be room temp), not a heating issue. Unless you are actually able to print ice sculptures. Since it’s 2 physically seperate items that says to me probably not a sensor issue. Can you verify through outside means that they are actually not heating? Printer and slicer both show no temp? To me this sounds like you may need to open a service request.
That’s probably a sensor misalignment issue.
Had a similar issue because of sensor misalignment.
Interesting. Since the bed and nozzle use different sensors, the bed heater works off main and the nozzle heater works off the regulated power supply ( my understanding, which could be wrong) I would have thought 1 sensor being out of alignment would not affect both components. With your issue you also were not getting any error message? And were both the bed and nozzle impacted? Were they generating any heat anyway that could be detected in some way?
thanks
In a way I guess I can see this, the sensor circuitry should be seperate from the heat power circuitry. It still seems like the devices would still keep heating until something timed out and it should throw an error or both heaters went to maximum heat and stayed there, in which case you should be able to feel it with your hand, unless the heaters burned out.
this talks about a heating issue, possibly related to firmware but does not specifically match all of your symptoms.
You can do the touch test.
Dial in a low setpoint and see if it gets hot. If it isn’t reading and gets warm, turn it off and tackle that problem. If bed and nozzle don’t warm up, different sort of problem. Generally I don’t believe in coincidences and two separate temperature indicators dropping out together would lead me to the board those sensors are connected to.
