howdy, im having a similar issue with my printer. (ender 3 pro with a sprite direct drive extruder(with bl touch), 4.2.7 board, and a nebula tablet kit) Whenever i try to whenever i try to calibrate my bed mesh, the bl touch misses the bed entirely and pushes to extruder (tool head) into the mat (magnetic). i tried to fix thix by changing the bed mesh min and max, but it didnt like that and yelled at me.
ENDER 3 V2 PRO, V4.2.7 BOARD AND TOUCH SCREEN KIT.
I too had a very misserable time getting SPRITE to stop crashing. My soulations turned to mechanical issues.
I hacked together a mount for the Touch relocation to match original locations. Works as intended now.
I cut off screws on the SPRITE carrage and removed the inner mount screw on the belt tensioner. no more crashing and bed leveling is normal. I got really tired of software solutions.
