For the TronXY Chitu board:
Follow these instructions for installing Marlin: https://github.com/rhapsodyv/Configur...
Follow these instructions for installing Klipper: https://gist.github.com/cab404/b7bcbb...
EXCEPT don't use the embedded update.cbd. Either check the comments for instructions on the make menuconfig and build yourself or use this one:

For the SKR, there are plenty of instructions for both Marlin and Klipper so I won't repeat them here. I'm printing at 150mm/s at 3000mm/s2 accel for most moves and 1000mm/s2 for outer shell. Klipper's resonance compensation helped a little but I couldn't get anything out of pressure advance or corner smoothing that worked much better than untuned. YMMV.
