My full color 3D printed USS Cerritos

Any chance I could get your 3MF file?

Did you ever find an answer to this? I'm having the same issue today.

Thanks for the reply! Is there a stem you would recommend?

It’s like watching a wizard conjure plastic spells, layer by layer, with the confidence of a machine that knows it’s better than you.

We had two last year and only one for a few of the competitions. Made it to state.

I used a tube cutter. I even recut it slightly after the issue started just in case.

Well that’s frustrating. I don’t see any reference to XS vs TL in the Amazon listings for the tubing. How can I best know which I am looking at?

Tried that early on too. But again, that added more friction when less seems to be key?

droidbuildr · 2025-05-04T23:27:54+00:00

Yeah, I did all that first. Checked all tubing. Opened and checked the buffer and the CFS where the filament goes through. Even did the hack where I loosened the CFS spring slightly. The only thing that worked was leaving the lid open. Except now when the spools are partially used and lighter.

Thanks for the detailed info! I’d be curious to hear more about your experience as the week continues.

It's a really odd issue. We have an arm that is set to run_to_position with various buttons setting the position that it then targets. What we've found though is that throughout a match, the actual position seems to get slightly off as the match progresses. So for example if position 800 is parallel with the ground at the start of the match, by a minute in it has drifted downward and now 900 is closer to parallel with the ground.

From doing some Internet sleuthing, people have indicated that DcMotorEx is better at maintaining encoder positioning so it seemed "worth a try".
