I only saw one other same topic and it had obvious damage.
I am getting this error, I replaced both nozzles to make sure, cleaned the ‘sensor pad’ best I could (nothing on it). it was working just fine- then it came up, so I do not think heat pad are installed incorrectly.
I was going to enter a ticket, but it will not allow without entering a bunch of stuff not applicable (like picture of problem).
A picture is not mandatory. A log file is though.
This can be a difficult issue to resolve - on my H2C I wound up getting the printer replaced under warranty.
You need to put in a support ticket.
I will come up with stuff to put in a support ticket. There is an * by picture, which looks like required. The ‘send’ option is greyed until everything is filled- but I will try
edit:
I tried again, it would not let me submit until I uploaded a photo. so I just took one of the error screen. then I submitted one. I did order the ‘sensor’ plate - since that is an option for the error. I went through everything twice and it certainly appears to be seating well. I’m not sure it would still be under warranty (heck, I’m not even sure how long it is)
I replaced the sensor pad- but no better. I replaced both hot ends- still the same. I loosened the left hot end heater, wiggled and snugged back up- still the same.
I did recently replace the left hot end heater, but printed some things after with no issues.
I have a ticket started, they suggested the sensor.
Good that the process is started. Work with them in good faith, but if they start going in circles you should politely but firmly indicate that you would like a unit replacement.
To be clear, asking you to run calibrations and tests after replacing a component is reasonable, while randomly asking to reset the machine and try running setup calibrations repeatwdly when nothing else has changed probably is not.
I believe it is out of warranty (don’t they just have a year warranty?).
Depends on where you are, but at any rate they need to be able to provide effective support that can get you back up and running!
I am in the States, bought it end of March, 2025
I had an issue with the Nozzle Offset Calibration one time when the rear Z-axis lead screw stripped out. Do you have significant play int the rear of the bed?
