Welcome to the SeeMeCNC Community

It was, of course, a 4-pin connector being stuck between the fan and the arm on the X side, mechanically pushing it over as it got closer! Thanks - hopefully I can get that corner to actually print now (and I feel better about spending the money for the accelerometer upgrade so I can stop waggling ...

Hi, all. I've been trying to solve my issue printing larger prints (15cm or so on a side) that end up using a lot more of the bed than most of my previous ones, and I've been unable to get things honed in right on the X tower, no matter what I try - as the effector/nozzle approaches the tower, it ...

I printed a completely flat tile similar to that while trying to test it, and it also exhibits the same problem where the corners aren't 90 degrees. Checking with a square, the entire edge pulls away from the square at an angle, so it's not an extrusion problem in that sense at least. The problem ...

This is PLA, the problem happens with both 7.5cm square tiles and 15cm square tiles, and I'm on a Rostock Max V2. The tiles vary in thickness from a few mm to over a cm thick, and all exhibit the same issue (it's inherent in the path of the print head, not a slope on the print bed, from what I can ...

You can't really see it in pictures - they look square to the naked eye as they're only a few mm off on each side. I've attached a picture of them tiled together showing the sort of gaps that occur.

I've been printing out square tiles for a project I'm making, and they're not coming out completely square - it's hard to determine how they're skewed exactly, but I would say that they're coming out trapezoid based on the way they tile. It's not a very big error - only about 2mm between square ...
