Thank you very much for the quick response. Regarding your PSU mount: Yeah I can imagine why this wouldn't hold up over time. PLA gets extremly weak at 55C plus and I don`'t think the PSU has any problem reaching that temperature because the volatage regualtors use the metal case as a heatsink. It really gets toasty under there. I would not print this out of PLA. PETG at minimum or at best something like ABS+. Currently my PSU is fixed to the bottom of the Ultimaker with some doublesided tape, which will be a pain to get off at anytime I would want to change it... Other than that I think it should be recommended to put the Ultimaker onto some feet to get some extra airflow to the PSU. Additionally plugging a 120mm 24V Fan into the 3rd PWM fan port (of the SKR 2.0) to use it as a Electronics Case Fan in Marlin is not a bad idea and can't hurt performance either. For terminal protection of the PSU I use this print: https://www.prusaprinters.org/prints/74538-mean-well-lrs-200-24-psu-cover but I could also imagine this to work well: https://www.thingiverse.com/thing:3572269 May I ask what problems you had with the SKR 1.4? What did you switch to?

Hey, great work on this one! My any means is there a chance that you could share the .stl file for the lid and the PSU mount aswell? That would be really appreciated. I'm currently doing this conversion with an SKR 2.0 REV B and it seems to work pretty well so far. But instead of using some extra boards for the Pt100 Thermocouples I used a standard glass thermistor for the bed (type 0 in marlin) and a B3950 for the hotend (type 13 in marlin). Other than that I will change the heatsink cooling fan for a 24V fan that I can directly control via a PWM port on the 2.0. The part cooling fans will also be replaced by blower fans (Link to mod: https://www.thingiverse.com/thing:4888655). This saves a lot of the guesswork and extra parts but also requires some soldering skills if you don't want to take the whole machine apart. But I think it's worth it.
