I built my lowrider for a 48 by 96 (1220 x 2440) bed.
I use the firmware.bin file that is in the “V1CNC_SkrPro_DualLR_2209-22.214.171.124-src” Download.
It works fine, except that the bed size is small, and if I home X, and X is to the right, it errors out, and I have to unplug the power and restart.
But that download does not have all of the source files, it only has the marlin directory and the firmware.bin file. If I try to change bed size (edit #define X_BED_SIZE 1220, Y_Bed_Size 2440 using visual studio, it errors out when I try to build.
If I use the Marlin-1CNC_SKR_Pro_Dual files set, I can change using vs studio, but I when I move X, it moves the right Z and X, and if I move Z, it moves only the left Z.
I tried overwriting the marlin directory in the second set above with the one that came in the working one, it compiles, but moves right Z with X, anyways.
