thanks for the reply. I think I will go for the option of installing the custom firmware.

Like the title suggests I want to find out if I can upgrade the hotend on my UM2 to an all metal hotend. My plan is to print Nylon CF/GF and other 250-300°C filaments, for that to work I need to get my hotend above 240°C (which is where the PTFE should start to degrade). So I looked around on the Internet and found some all metall hotends, but they are using a heating cartrige which needs more power. So my Question is: - can the UM2 Mainboard handle 35-50W Heating elements? - are there available upgrade kits for the UM2? - is here someone who has experience with new all metal hotends? I found some Hotends where I would have to print an adapter to fit the hotend to the UM2: -E3D V6 : the standard/cheap hotend -E3D Revo : sadly no hardened nozzles -Bondtech Mosquito: pretty expensive but it should do the job and be reliable -Bondtech Copperhead: the cheaper alternative to the Mosquito (an metal adapter would be needes but perhaps no new Mounting system on the linear rods?)) -Phaetus Dragon: the cheaper alternative to the Mosquito -Creality spider: pretty new, no opinion an that particular one I found some people that are using 35W heating elements and very few use 40-50W. But they havent specified if they upgraded the UM2 mainboard for that purpose. I would guess it should be finde to use 35W because there is a dual hotend option which would require more than the singe extruder version.
