Good point, I have mainly been printing these items for the hydroponic tower. I do have other versions that I can check. I think after this set prints I will add some basic shapes in different orientations to see if there is issues still.

That being said I did print some other items that were stacked and each one is much thinner but there are no artifacts on the outer walls.

Thanks for your reply, to your point yes they still fit, been having this issues for a bit now as I’m up to about 40 of these netcups and the associated other pieces for the grow towers.

I think the belts are good, but will double check.

Easy there pussies can be useful, unlike that shitheel.

I can’t speak to multi colour perse, however the creality K2 went on sale today for certain countries and they have a 50% off sale for a limited number of units, they sold out today’s stock but will have it again tomorrow then they will drop to 40% then 30%. Might be good if your willing to be a beta tester essentially.

The Prusa units seems to waste less filament.

That sounds like an interesting plan, my E stepper driver was what acted up on my 4.2.2, it seems to be working now, but I’d like to see your config in case I need to go in that direction.

Update:

I took everyone’s advice and tried all the suggestions. In the end I completely disassembled the printer and made sure everything was square or perpendicular where it needed to be. I think maybe the dual z screws were binding, although when I took everything apart I noticed that I did not use the Y cable for both z steppers, I ran the original short cable to one motor and

the Y to another, not sure if that had any effect or not, but now the Y cable is running both z steppers.

It does seem to be better, but I still have the dip in the bed, which is still a bit of an issue for the BL Touch, but not nearly as bad as before. I may have slightly bowed it when trying to crank down the levelling wheels.

I think that the z screws were binding just enough that it couldn’t keep up with the micro adjustments, I guess time will tell.

Thanks for everyone’s input and advice, hopefully it’ll run for a couple more years. If not then a replacement Bamboo might be in order.

Now I just need my resin printers to stop failing prints, but I think that’s more me than the printers. lol

Thanks everyone.

It could be that I am cranking down on the wheels too much. Thought that maybe they were loosening off so tried to tighten them. I’ll keep that in mind when I reassemble the unit.

Thanks.

I did a probe accuracy test yesterday, 0.002. So I think it’s good.

I have the entire printer torn right back to square one. Will double check everything as I reassemble.

Did a couple prints yesterday with no BL touch, bed level the four corners, seemed good a bit of first layer micro adjustments.

Went to perform another print (same as the previous print) and the bed was out of whack again. The bed level test said that the right side was out half a turn on the knobs.

I’m starting to think it has to do with the dual z motors and not staying timed or level with each other.

Will see how it works once I get it all back together.

Thanks.

Currently I’m doing the bed level with everything at room temperature.

I’ll give it a try heated to see if that is causing the warping.

Cheers.

I have it clear the mesh, take a new mesh as default, and load default mesh in my start profile.

I though it might be the same, but it does make micro movements along the board to adjust for the mesh reading.

Double checked the operation of the BL Touch, it’s working and no issue (mechanically at least).

I did a complete relevel of the bed and still had an issue in the middle of the bed. Commented out the bed mesh in my config and had a better result in the middle of the bed.

Running with no BK Touch for now.

Thanks.

This is a bit older bit still has good information.
