TronXY P802MA Warped Carriage Levelling Washers M3

thingiverse

You can fix warped x axis carriages for the lead screw attachment by printing 3mm washers with outside diameter of 4mm, inside 3mm and 0.2mm high. I printed like 100 for less than a metre of PLA. Took a whole minute to print lol. Then I just packed the washers between the screws holding the lead screw guide/nut to the carriages. You know when you have it right when the rod falls through the nut under gravity or a very small tap and if it is parallel to the guide rail. This adjustment process took about an hour because of the fiddly nature of it. But it worked like a champ. A razor blade and toothpick helps to align them. Less material than printing a new carriage and faster. I plan to epoxy this in place because that nut should be a permanent part of the carriage. It's customisable, the code is included as an scad file.
