MMU works but wipe tower came off
So I assembled my MMU3 for my MK4 and started a test print. It actually worked fine, but the wipe tower didn't stick to the plate. The print finished but there were some spaghetti around the printer and some of it merged with the object.
Is this a common issue? It didn't look like the first layer of the wipe tower was actually covering the entire area of the tower, so there was less material adhering to the plate.
RE: MMU works but wipe tower came off
I believe I have exactly the same issue. Print worked well. Spaghetti wipe tower.
Any idea what I did wrong or what to do?
RE: MMU works but wipe tower came off
at a guess, I would say that you probably had poor adhesion.
I Wash my build plate with HOT WATER AND DISH SOAP, rubbing vigorously with a new dish sponge, then rinse well with fresh hot water and dry immediately with plain paper towels (both sides), (Keeping your fingers OFF the print surface)and then I put the heatbed on the printer and bring it up to print temperature.
I do not use Isopropyl alcohol...
And I usually use 70C on the heatbed for PLA

Thanks for your tips 👍
I use the texture sheet and clean it with IPA 90% all the time. My bed temperature is at 60.
I will try out the higher temperature and cleaning it as you suggested.
Will the satin sheet be a better option for PLA?
RE: MMU works but wipe tower came off
I use textured and satin interchangeably and rarely use smooth, because I feel it's more fragile.
