Wipe Tower Warping

I love my MMU. However, I cannot get my wipe tower to stop warping. It starts off fine but after several layers it starts to warp and the rocking back and forth eventually loosens it from the platform. I have tried glue, hairspray, tape and nothing keep the wipe tower stuck to the platform. The print itself sticks no problem. Am I the only one with this issue? I've tried changing the width ... no help. At this point I cannot complete any prints.

Re: Wipe Tower Warping

Mine seems to stick just fine.

Have you moved it to another part of the bed?

Does this happen on the pre-sliced files too?

Do you have frequent color changes, or lots of the infill?

Re: Wipe Tower Warping

Scrub the bed with a paper towel and acetone (not nail varnish remover which contains oils) and lower your "Live-Z" by 20 microns. Maybe you need the "Hyper-fine Bed Levelling".

I know it is really weird that this is just happening to the wipe tower. I can print a flat disk and not see a bit of warping but the tower will always warp. I have moved it, resized it but it still warps. This is on the sample files like Marvin, gear bearing, chimera and any of my prints. Four color, two color, or single color does not matter. Just the wipe tower warps. Like it is laying down a lot of PLA. Infill I set on my prints was 20%.

Have not tried acetone just IPA. How about ABS juice, or that won't work with PLA. I had no problems printing before the MMU, but was not using smart wipe tower obviously. I have set my Z adjust to the point that the layer is squished totally flat. Making it almost impossible to remove.

Acetone will effectively refresh the bed's stiction. Before I took delivery of acetone, I used ABS Juice quite successfully, but it does leave and ABS residue which will require cleaning off at some point...

Re: Wipe Tower Warping

Hi,

I have the same problem! The wipe tower has massive warping and after some layers it jumps from the bed. All other objects are sticking perfect. It seems as if the z-caibration doesnt work properly for the wipe tower. Maybe it's a bug?!?
Do you have any solution for this problem?

Holger

Re: Wipe Tower Warping

Hi!

I've edited the gcode manualy, so that it prints the first layer of the wipe tower's brim with half the speed. Now, it works fine!
