Target Temperature 1500c

Randomly during prints my printer will just yeet the target extruder temp to 1500c.. then of course, Maxtemp error..

Here's everything I've tried

- Replaced the thermistor 5x (current one installed is a new OEM)

- Replaced the extruder heater

- Removed octoprint entirely

- Reflashed firmware

- BOUGHT A NEW RAMBO

 

Currently Testing

- Uninstall Prusa slicer and reinstall 

Other Ideas

- Throw out window

- Install old firmware to printer 

- Test older version of slicer

 

I have never been so defeated by this printer, this has been trial and error for over a month.

Revert

If this started happening after a firmware update, I would recommend reverting to the prior version.

This a really odd one

This is a really odd one.  Please post back is downgrading your firmware works.  I am sure someone else could use the confirmation.  

The firmware installation / upgrade must have corrupted something.

On prusa website you find gcode that should work, these are for printing the printer parts.

Then you know it is the slicer.

Topic starter answered:
ooops

 

Aheh, so this is where the problem started at least. However the issue started happening with other filament profiles so I never thought to check if this was the case. I saw someone mention while researching yesterday that if you enter 2400 it will automatically revert to 1500 and 2400 is an easy typo. After running into this error a lot, I'm hoping that the extreme temperature caused issues with the rambo/thermistor causing crashing on other filament settings.

That

That would explain it.  Stupid mistakes can often be the most difficult to figure out.

Another option?

You could try resorting to sintered metal instead of plastic!
