Ah, who cares! It’s tuesday…
Here is my RC4, same changes compared to stock as the old one:
.) Baud rate is set to 250000 - be sure to set it back to 115200 when using your printer with Linux!
.) TAZ specific values added (steps/mm, …)
.) New value in 1.1 “Travel acceleration” set to 1200
.) Enabled FW retraction with my best values for that
.) Enabled SD Support (of course…)
.) Reduced extruder acceleration from 3000 to 2400. 3000 is TAZ 5 default, but thats to high. Extruder is missing steps, resulting in blobs when unretracting. 2400 is the highest safe value for my extruder.
.) Enabled filament change possibility
.) Preheat options for PLA, PETG and ABS
.) All “Lulzbot-specific” changes (only Boot logo and another font, to be precise 
)
Have fun, at your own risk as always
