I do somewhere how do you get them out? Is it just pressed in with a pin? Also should I try and reduce the load on the bearings or just leave them. My tube has some pretty deep groves already. About how free should the gantry slide? I adjust the x axis a while ago it’s really smooth now but debating if I should pull the lead screw nut on the Y axis too see if that one is still smooth once in a while my steppers will freeze up on the Y axis mid cut. I’m pretty good about wiping all the tubes and lead screws clean the applying new lubricant since I notice using a wet lubricat attracts a lot of grime.
