Looking to do an overhaul

hey I’m looking to do an overhaul on my crossfire pro. new bearing and possibly new rails. I have cut thousands of parts but seam to have gotten some warping on the x axis rail. has anyone order replacement parts? I’m not having any luck with response to Langmuir, not blaming I maybe be emailing the wrong area of expertise. justing looking to keep my table in optimum condition.

as well has anyone experienced there tip height control needs to be reset in the the psu housing, it seams to come loose or doesn’t recognize it. I have to take all the screws out to access the board and reset frequently before cuts.
