Ah OK, I've worked it out (by taking the dog for a walk and explaining the problem to her). Customisations to resources go into `~/Library/Application\ Support/cura/5.2/`

Hey I know this is an old thread, but I've been away from printing for a while. I've just tried to fire up my printer and it seems that things have changed under my feet - Cura has upgraded itself to 5.2.2 and has forgotten all about how to talk to a ProForge3. Any clues about how to get back to a working configuration? I've tried importing the stuff from the Makertech-Cura_Resources repo and that failed (twice: first time round it didn't seem to change anything, second time round Cura just crashed at startup with a stack trace). Does anyone have a working copy of Cura on MacOS that can print to a ProForge3? I think I'm going to have to go back to old versions of everything and work forward, which seems pretty tedious especially if someone has already been through all of this.

Do you have a part number and source for the thermistors that you have provided? I've heard from someone that built the DSH kit that he had a problem with the thermistor cables failing from the head movement, so it might be good to be able to get spares of parts like this.

@Johannes Weis is that a config change or do I need to build my own firmware?

So what's the ETA on a usable firmware? It doesn't have to be perfect. If you release the source code that you have so far you'll get lots of assistance in improving it.
