Thank you. I will try that. One more question though. The PTFE coupler in the hotend is burnt and probably should be replaced. Can I use the UMO+ one?
Nope sorry. UMO+ coupler is really really different to the UM2 ones. If you need to buy one I would highly suggest to get a TFM version + fixed spacer (any UM reseller has them or also 3dsolex TFT) since they last MUUUUCH more print hours. Is one of the parts of the upgrade that I love most since I don't need to change the couplers so many times. From from 50-200h of umo coupler to um2+ TFM/TFT 500-2000h is a BIG leap in time and money saving.
Sounds good. I figured out that I needed a fan splitter, and I had one lying around. Works perfectly now. Thanks.
Um2 fans don't start to move until 70-90/255 they work with an option called Fan minimum PWM (set it at 80 on the @Amedee builder) and also use Fan PWM kickstart. 300 millisecs or more works.
Try this adjustments and build a new firmware. I think that should fix the issue.
