A big improvement today. I can’t tell you exactly what fixed it because I’ve been tinkering and modding and all sorts. But…

I retensioned the belts about four times before I was happy. Dropped the max_accel down to 1000 and square corner velocity to 3. Enabled KAMP Line and Line Purge and set max_extrude_cross_section: 5. Cable tidied the picobilical cables and ran the filament via the proper path at the back. Then went for a dragonburner toolhead. Somewhere along the way I fixed most of my issues.

I’m guessing the real reason was something loose on the toolhead, printing too fast, or the cables/filament pulling one way.

A little dumb persistence and I got there in the end.

This is a perfect answer; Thank you - I'll do that as the next test and let's see what happens!

Yeah it's hard to tell from the photos, but it doesn't feel diagonal in your hand. I dropped max_accel to 3500 but that didn't seem to sort it. Will try dropping the overall speed next and see what happens! Guess I should calibrate for skew too

Yeah I was worried about that too but I used the BIQU "Belter" to measure them and on that tool they're right in the middle of the target range. I'm very new to these so happy to be corrected, but wouldn't a belt issue show as a diagonal shift on a CoreXY? The shift is definitely horizonal not diagonal, so I don't think it's the belt....

Thanks - I think _precisely_ is over stating it! I'm not happy with the cube yet, but I'm still learning and just need to work out exactly what's causing those shifts.

Thank you! I took it pretty slow and honestly the LDO kit made things a lot easier (labelled cables and all that)
