So I've put it off for a long time. Going from version2.x to 3.x means ALOT of changes in the config.g file. As prep for doing it on my TC I first did it to my CloneR1/Duet machine. It took a whole day of wack a mole bug fixes before I finally got to the point where I could start to do PID tuning. As I had feared the move to RRF v3.3 is a PITA!!! First it can easily put the files for running the wifi server into a location that may not exist yet(yes it can happen even though I went from 2.x to 3.0 first!), then there's the switch to the "PIN" settings (!), then the added lines for the PanelDue and the CoreXY kinematic, then the PanelDue FW has to be updated as does the DWC! AH!!! NOT FUN! So... anybody here have a sample config.g file for V3.3??? and then there's my fears that all my subscripts for priming and wiping won't work!!! Anybody here been there and done that???
