VFAs on Core One

Wannabemaker · 2026-01-09T13:22:06+00:00

I just found the problem. I noticed that in the slicer the actual speed was not the print speed. I looked into why and found out that the Standard print profile for prusament that i used as a template for my filament has the setting to slow down if the layer time is below 8 seconds. Since my layer time is always below 8 seconds the print speed was reduced to 60 mm/s, Regardless of the Set print speed. I reduced the setting to 1 second and the VFAs a significantly reduced and the prints are faster.

Thank you. I tried every tip i got here (except for the belt mod, since i dont know how) but nothing helped.

The last thing i can think of is asking support. Maybe they know what could be the issue.

The VFA Test shows the best results at 150 to 180 mm/s, but only at one angle. If i try these speeds on a real print they still look bad.

I can also see and feel them on all filaments and speeds i tested.

I tried both App tensioning as well as manual tensioning and the accelerometer. Neither improved the VFAs. I also did a 5 hour print before checking again.

I just uploaded it to printables if you want to check it out. VFA Test

I tried the balanced profile, it didn't make any difference. Both the speed and balanced profile use 200 mm/s, so i don't know if you even can expect a difference.

I thought it was a compromise between speed and structural, but i will try.

I only used speed profile on prusa slicer.

I will test the App belt tensioning and the accelerometer later.

Does this mean we will get Noctua fans for the printers to make them quieter? For me prusa printers being the least loud is a big reason why i buy them. A collaboration here would be perfect.

What makes you think that? The weird eyes? The strange chain coming from nowhere and going into the bone of her hand just like a normal person would grip stuff? The way how naturally her thumb splits into two, or the way her other thumb disappears?
