  • Thanks! I was running some models on my RX 9070XT, but only Ollama works flawlessly. I couldn’t make llama.Cpp to run Gemma4 or the newer Qwen - maybe I’m hitting that incompatibility, but probably it’s the skill issue.

    P40 doesn’t look very appealing. 32 GB V100 costs about the same as 2xP40, less VRAM in total, but it’s faster, will use less power.

    But I’m not sure if I follow you on the PCIe… If I run a model that spans multiple GPUs, doesn’t PCIe bandwidth matter?









  • All right, I think you are right on the curling upwards. I started another print, which is also using similar hexagonal sides, but is more massive - hexagons are larger, and walls are thicker. And it warps up visibly! When these overhanging arms on upper part of hexagons start printing, they just warp up while cooling. Then when nozzle comes back for the next layer, it hits the warped edges, pushing filament to the sides and making these artifacts. It didn’t break any segments, as they are thicker, but I bet that’s what happened in the original print.

    On the new thicker print, the base of the model lifted up from the bed on one side at some point. I was watching the first two layers, so this happened some time later. Gonna try to slow down the print, lower nozzle temp a bit, bump up the bed temp a bit. Will see what happens.



  • Thanks! I’m a beginner, got the printer about two months back. I didn’t do any special tuning apart from auto leveling the bed.

    I printed a temp tower with this filament, and it was okay from my viewpoint. Long overhangs were droopy on lower temperatures, and it had stringing from pointy ends on higher temps. I printed a few PETG prints before, but nothing with such fine details as this hexagonal thing.

    Can you point me to some good source of info about tuning? For a noob like me it is hard to tell good resource from slop-compiled one…


  • Thanks again for the valuable feedback! I printed it again with higher temperature, 240. It didn’t change much, overall. Same print errors remained, however I got a few less of broken hexagons, so overall the print feels more sturdy.

    Looks like the majority opinion here is to blame that all on wet filament. I don’t have the right equipment to dry it, so I’d probably just avoid printing similar parts with this spool, and take more precautions when it will be time for a next one. My drybox spool holder build is almost ready.






  • Thanks! I think I unpacked this filament about a month ago, and it was on open air for about two weeks, in 40-50% humidity. then I put it into a dry box with a box of silica gel, and it stays there at about 20% humidity. Until I take it out for a print. Is silica gel good enough for drying? I don’t have the drying machine.
