I’m at a total loss, I have tried so many things, read so many things. Checked belts, checked lube, and pulleys, all collets tight, bed surface . Etc. I even did some upgrade improvements along the way, adding a metal extruded (though doubt has anything to do with problem). But when I print anything, after a few hours I will get a shift printing towards the rear of the bed. Sometimes 1/4” or more, and on some prints, because I didn’t check it till later, it would shift a little more, again in the same direction. The bed is solid, belt attachment is solid, top surface is solid.
Im wondering if it’s a thermal issue with the main board underneath inside the enclosure. I have attached a few sample “shifts”.
really appreciate the help on this...
thanks
ps, I also have an issue on brand new Bowden tube, the xxx, where it pops out of the push coupler. Brand new coupler and brand new tube per Dr fax recommendations. Is definitely in far enough as the markings on the tube are well up from the end where it’s suppose to grab. Could it be inferior push couplers? They came with my metal extruded kit.
