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! :)
Awesome breakdown! My motor makes a TON of noise sometimes. It seems like it's when it's about to change direction. I haven't taken mine apart yet, so I'm not sure HOW it's changing the direction it rotates the spool, but I assume it's mechanical? Either that or a polarity change? I'm not smart enough for this stuff. Any idea? I mostly want to stop it from rotating different directions because the noise gets really annoying, almost like it's loading up and struggling, then the direction changes and it's quiet again for awhile.
That's wild! From what I recall, it should only turn in one direction. The motor turns the spindle and it's that eccentric part that causes it to only engage every so often. That's quite an interesting issue. It' not hard to pull apart and investigate though. Mine doesn't make much noise at all when rotating.
@@directedt3ch hm. yeah i'll take mine apart and get back to you. Eibos_official commented this on a reddit post: "To be more specific, it would rotate the spool one turn clockwise and then one turn counterclockwise. " So it's definitely designed to do it. FWIW, i just bought this. Maybe it's a new version?
@@directedt3ch I went through and opened it up. Lubed the gears. Tightened everything back down. I suspect there was some play in the shaft that holds the rollers together or the screw that holds the rollers+gear against the gear for the motor were the issue because it's dead silent now. Anyways, hope this comment helps someone else if they're having the same problem.
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!!
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!

@skinnybricks Thanks! I'm so glad you fixed it and then took the time to come back and comment to help others.
@@skinnybricks That's interesting! I just turned on mine and it is only rotating clockwise (when I look at the right side).
One of ways to ease screw insertion might be putting heatshrink over tip of screwdriver, and inserting screw in it
Good tip!
what is the voltage of that motor actually?
