RATOS 2.0 - Getting multiple heater related errors
After updating to the newest version of RATOS, I am getting multiple and different kinds of heater errors.
Can anybody help me to figure out what's wrong?
I have my suspicion on my heater thermistor is toast, but I don't know.
That's why I am asking 😄

Can you upload your klipper.log file?
Where do I find that?
Ah okay

So either a bad connection somewhere or a break in the wire
Oh yea okay..
If it is a break would I need to buy the whole heater (since it is a rapido), or can I simply fix it by cutting off the part where it is broken and either crimp on a connector or solder a new cable onto it?
first you need to figure out if it is a connector issue (connection at the MCU, connection at the hotend, etc). If all those are fine, then seeing if it broke off the ceramic area. Depending on what you find will determine the fix
It was squished in here under the plastic.. had to screw it off to remove it.. don’t if that could have been the issue
had to screw it off to remove itwhat does that mean?
Had to loosen the screw (left red box) to free the thermistor cable (right red box).
Had to rephrase that. Did not even understand the first explanation myself XD
Looks like the issue is gone.
Can try to do a test print and see if that can trigger the issue again.
Ok I see now the mount for the extruder was pinching the thermistor wires. Yet that isn't great, but not sure that is the root cause of your problem.
Yep. I have printed for an hour now and still no problems.
Seems like you were correct in your first assumption, that is was a loose connection at the plug at the near the hotend.
However, I will do a little more testing before, marking the problem as solved.
Thanks for the help so far 😄
