Fuse 1+ print problem

Hello everyone, in the last 2 days I can’t print anything, because in the preparation of the bed printing it forms bands of sintered powder that ruins the powder bed.

Anyone experienced this kind of problem that can help me?
Thank you

I’ve experienced this n so much more… hard to tell off the little information and what your running/history.

However, what finally fixed all of our preheating and print start errors like this was bumping up to a 70% refresh rate with Nylon 12 GF.

Also, printing the vacuum attachment and completely sucking out both trays of powder AND rotating the dozer three complete rotation’s and sucking out all that powder, that was close to the heat of the previous print.

Lots of “wasted powder” $$$ essentially fixed all the warmup/initial printing issues like this.
