Why does my H2C reach 140ºC?

[user_1969025712]

Good morning, After the first and second betas, I'm currently experiencing issues with version 2.07.00.55-20260514170313. My H2C printer, even with the left nozzle disabled, maintains a temperature of 140°C from the beginning until the print finishes. This only works if I adjust the machine's screen to 0°C.

Does anyone know how to stop this, or is this a problem with the last two betas?

…there you can see how the left nozzle stays at 140… and then I set it to 0…the same thing happens in all the templates I've sent so far… even though they are different file models.

(I don’t use the left side; I only use the AMS with the four colors on the right side.)

Thank you very much!. (I put it all in English… so you understand.)

This may be a bug on the preheating change they put in the beta for the left nozzle. Its not normal, especially if it stays there throughout the print and not just during the startup sequence.

With BS 2.6.1.05 beta and the new H2C V01.01.50.00 beta firmware it doesn’t happen. My left nozzle remains at low temperatures (36 degrees Celsius) all the time while the left nozzle is printing.

Yes, it does apparently. I have the beta and just realized during a right nozzle only print, that the left nozzle maintains 140 degrees.

Its not a bug, it was a bug when it didn’t heat. Usually 140 is picked because the nozzle will heat fast from that temp, yes not damage filament if its heated over a long term.

Are you sure? Mine doesn’t
