I have an Ankermake M5 that I hadn’t used in a while and recently got back to printing some stuff. I had a few prints come out well but then turned my extruder into a giant glob of melted plastic on an overnight print. I ended up just replacing the whole extruder as there’s been some revisions and I figured it would be nice to upgrade, and replace the v-wheels and all that.

The new extruder initially had a ton of problems with stringing, but increasing retraction fixed it. The problem that I can’t seem to figure out is curved surfaces are now sort of wavy. It’s regular - turning into vertical peaks and valleys. I’m doing a print currently with the speed turned way down, but the issue persists.

Any ideas?

edit: After some trial and error, I figured out that it was a slicer issue. I was using the EufyMake slicer because that one can send jobs to the printer directly. When I resliced in Prussa, the issue disappeared.

    I checked belts, they’re good.

    I’m wondering if there is enough of a weight difference between the old and new extruder to have fouled the configuration.

      Yup, changing out your extruder, even if to an identical one, changes the weight just enough to cause this. Input Shaping is indeed what you want to look for, it’ll be different depending on the printer. Some you have to adjust config files, some you can actually do in the slicer now.

      I’d give OrcaSlicer a shot, it has some built-in tuning mechanisms
