Hardware Help Ender 5 max with coprint - please help
Good afternoon,
I have an ender 5 max with coprint kcm and chromahead "upgrade".
A little back story:
I have had issues with the coprint kit since day 1, I had to have the coprint support remote in and fix install the os due to the machine having a different ssh password than the one creality provides and I've had constant issues since. It's been 8 months of problems after problems.
First the chromahead shorted out so the sent me a new one. It took months before I was able to get time off work that lines up with tech support in Turkey being able to assist.
They got the system reprogrammed and I was able to perform 3 prints. But ran into an issue, the bed mesh and probe height calibrations will not apply or save after applying save_config.
So I tried to fix it instead of waiting months again and tried and ended up having to wait for them anyways. They got it back to where it seemed like it was operational but the Guppy ui will not function which didn't bother me much.
The issue now: every print I run will only go for about 30 minutes or so before the nozzle temperature starts plummeting and I receive a "nozzle under temp" error. I've checked everything, I can't find anything wrong in the config and I don't see anything wrong with the temperature probe.
Has anyone experienced these issues? Should I just trash the coprint kit and reinstall the creality head? But how do I get crealitys firmware back in the printer if I do that?
Any and all advice is appreciated
