When i got my polyphemus a month or so ago, the motorized oring wheels weren't making sufficient contact with the rollers on one side, and so on one side the spool on that side wouldn't rotate by the motor. This was during when Chinese new year was going on so i had to diagnose and fix it myself. I fully disassembled everything, down to removing the oring wheel assembly and also the motor. My solution (and it's still working today, months later) was to remove the wheel assembly, then remove the oring from the wheel having the issue... I placed a tiny droplet of superglue to the offset portion of outer diameter of wheel, i put that drop on the portion that sticks out the most (the portion that contacts the rollers), waited for that glue to fully cure , reinstalled oring. What that did is to raise the surface area of that offset wheel to make more sufficient contact with the roller. After a couple adjustments to the motor gear and wheel assembly gears (had to make sure they make sufficient contact too), tightened it all down and it's working great. A few weeks after fixing it, Eibos finally contacted me and sent me replacement wheel assembly and new rollers too. I'll keep those around as spare parts since my DIY fix solved my issue. 👍😄🤗
I don't see any reason for concern on those particular parts. Time will tell though. I've been using my Eibos Cyclopes for over a year now with no issues.
Could be they have made the rods not very rubbery because it might interfere with when the spools are connected to a printer and being rotated by the extuder not sure. Thanks for the video, I was wondering what those O-Rings are for.
I really have no idea why they chose the hard rollers. They seem to roll fine when the motor isn't running. Isn't it wild that they give you replacement rings that are CRITICAL for operation, but don't mention what they are for or how to replace them? Wacky! :)
Placing the motor right next to the heating element is not a good design, as heat degrades the lifespan of electronics. This is better than the Cyclops, but they still have a work to do, the design could be much better.

That's was a really smart solution!! THANK YOU for sharing!!
One of ways to ease screw insertion might be putting heatshrink over tip of screwdriver, and inserting screw in it
Good tip!
Thanks for the teardown! Any thoughts on the build quality of the heater element/logic board/fan?

Great, went ahead with the preorder. Thanks once again!

what is the voltage of that motor actually?
