So I’m having this issue with my laser (see video). My Ruida controlled 50w Blue and White Chinese laser seems to be ignoring the limit sensors or switches and just grinding into the origin. Makes me think that if I keep doing this it’ll break even more. The googling has not turned up much, can anyone recommend a solution? I’m also trying to find more info on tightening the belt tension and lubricating the carriages ( I tried and the only appreciable change seems to be the movement speed increasing dramatically and) and especially had trouble because the x direction tension screw is sorta buried in the machine and theres not much access. Any tips are greatly appreciated!
TL;DR: Video shows grinding when hitting reset. Also how to clean and then grease rails? Z bed rails? Adjust tension?
