@boldnuts I have!

@boldnuts I have, and I'm getting an average deviation of 0.060.

@Phaedrux Thank you for the incredibly quick reply! I have in fact went through that page and checked build quality, squareness, tightness of carriages etc. Nothing is out of place that I can find, and I cant see any effector tilt according to the bubble level on top.

Hi all! Finally back at it with my Tevo Little Monster I have converted to a duet wifi, smart effector and 360mm magball arms. I'm so close to getting it up and printing I can taste the PLA. I've got my firmware all setup and can actually print, but my prints are coming out skewed. On some sides the infill wont touch the outer walls, and others it overlaps by quite a bit. I'll attach my a photo of my heightmap, which shows the issue that is translating into my prints. Anyone know what could cause this? It's my first delta printer, so I'm not really up to snuff on the tuning of issues.

@joergs5 sorry for the huge delay! It's been a crazy busy month. I went and got married and had my honeymoon band have been out of the game for a month, but I'm ready to come back at it strong! I can't really seem to find much I'm the way of the extrusions being off from each other. I can't really connect the carriages to see if they bind, but using my metric tape and digital angle gauge, everything seems to be super square. I've even replaced the vslot wheels and bearings.

@joergs5 that's a pretty awesome article. I might try that, but since my issue isn't consistent across the print bed, I think it will only help on smaller objects. I'm going to re-print some parts, tear it down and rebuilt again. Just to eliminate any discrepancies in the adapters for my magball ends I may have. Also, how important is 100% even belt tension?

@joergs5 it theoretically could be warped, but it's a circular mirror, and happens on all areas on the bed. And a G29 produces a pretty nice grid.

@joergs5 I really don't think it could be the filament warping. It has happened with multiple filaments, and multiple materials. The printer is locked away in a closet under the stairs like Harry Potter. Lol so no windows or anything like that that could cause a draft.

@joergs5 Unfortunately I don't think that is the issue. I've taken all the towers off and laid them next to each other and the length is so even that there is no difference with all 3 being lined up with 2 machinist squares.

@dc42 Thanks so much for the help. It does not seem to be printing skewed at all in the Y direction. Just in the X. Would the steps/mm need adjusted for just the X Axis then? Also, I am 100% confident in the rod lengths being correct at 360mm.
