Please, make sure that all cables are properly connected to Extruder PCB, check extruder cable connection with PCB and Motherboard.
Make sure that the heater&thermocouple is properly connected to the Hotend as well (as in the picture):
.
Besides, do you have the newest firmware installed?
Hello Marta, thanks for the advices.
I didn’t had the time to check cables today, but I’ll do tomorrow.
The most strange thing is that the message error appears a printer power up, before the UI launch, and occurs randomly.
I managed to run the printer and tried a plate calibration, but it failed.
Sometime at printer power the message appears again. And each the hotend temperature is really high.
I have one question : Since the plastic part of the hotend melted, can I do some tests with the printer anyway without problem. Or should I replace the hotend first ?
I almost forgot : I have the latest firmware : v1.4.0
In that case, if all cables are properly connected and the error still appears (and the Hotend is too hot), I recommend that you replace Hotend and Heater&thermocouple/Extruder cable/Extruder PCB. All these parts can cause this problem.
If you have a multimeter, please let me know. We will be able to check which part causes the error.
As for the tests, I recommend finding the root of the problem before further printing.
I asked Zortrax support team about this error too.
They asked me to measure the heater resistance and the extruder cable conductivity with a multimeter.
The extruder cable seems ok.
But the heater resistance displayed 14.6 ohms, and not 15 - 16 as the support team suggested.
I hope it could help.
I am a figurative sculptor and hope to continue printing with the Zortrax M200+. I have great result !!
I am also getting the same error but if I turn the printer off then on again it dissapears? I have changed the thermocouple & heater to a new one. When I changed to the new one I had no error. I havent used my printer for a while.
I replaced the thermocouple & heater too and the error still was here.
But then I stepped back to the 1.3.2 Firmware and now the printer works like a charm
