I am in the process of converting my LR2 to LR3 I have loaded the firmware based on this thread and now im getting the M420 error message. I have used the firmware in this link Release 3/22/23 bugfix rollup · V1EngineeringInc/BIGTREETECH-TouchScreenFirmware · GitHub
Make sure to unzip and leave all the files on the SD card when you flash.
Did you also update your SKR Pro, you should?
i downloaded the zip and unzipped it and left everything on it didn’t change anything. I haven’t updated the SKR Pro which firmware file is it? V1CNC_Skr1p3_DualLR_2209-2.1.1
great those two files corrected the issue although the z is noiser than it was on my lr2 not sure what that is about but it lives and moves. the z zero is up or down to the touch pad?
Make sure you lube the leadscrews. When you home it will go up and hit the end stops, and sets that as Z200. Down will lower that number, but don’t type in G0 Z0 and expect it to go down. There is only 80mm of Z travel.
