Hello everyone. I have this issue, hope somebody can help me:
I have a Prusa with Marlin firmware. It have been working fine, up to I decided to update my Ultimaker Cura slicer from 3.2.1 to 4.6 (latest version until now).
Now, printer doesn't work. This is what happens on Cura:
- Printer gets connected as usual.- Extruder temp shown a fixed 358°C value with extruder at ambient temp (about 20°C).
- When bed heater order is sent from Cura, cooling fan starts (such as if ports were swiped).
- When bed temp sensor is disconnected, extruder temp shows 0°C, and viceversa for the extruder temp sensor.
What I found when tried to open Repetier Host:
- When connected, it shows: "Extruder switched off. MAXTEMP triggered !".
- X and Y axis works fine.
- Z axis sometimes doesn't word.
- Cooling fan works fine.
- Bed heater and extruder don't work (heaters don't turn on).
- Bed heater temperature is shown fine.
What I have tried so far:
- Send M999 code. Nothing happend.
- Send M562 to reset temperature fails.
- Send D0 and D1 to clear EEPROM and Reset. Echo: Unknown command.
- Sensors are ok, I tested them and in both cases resistance is about 100k.
- I uploaded again Marlin software to the Arduino (the version I was using and I was sure it was working fine).
- I uninstalled 4.6 version and downloaded 3.2.1 again, but the problem is still there.
Be warned that I haven't made any change in the printer hardware or connections. Just updated Cura software and that made all this ha´ppenns. Hope you can give me some tip to help solving it. Thank you. Gabriel.
Printer not working after Cura update.

Solved, it was a faulty connection on the temperature sensor (a pin was broken).
