Hey everyone! I recently upgraded my Crossfire with the XL rails and lead screw but now I cant get the set screws to stop coming loose and have scrapped several jobs because of it.
What I’ve noticed: excessive runout on the Y axis when the gantry moves to the front of the table, it vibrates and wobbles close to a 1/2" it looks like. When I slow the job speed down to 10% you can see what looks like a substantial bow in the screw.
Also it seems like the lead screw is too short to get a good grip from the set screws on the coupler end and the bearing holder end.
What I’ve tried: oil or greased lead screw seemed to help a bit, loctite on set screws but still come loose. Washers on top bolts of gantry holder to change angle in case of binding.
Anyone else having these issues or did I get a bad lead screw? any help would be appreciated. I’ll try to post some videos so everyone can see.
