That’s about the tightness.

What wheel pulleys are you using? Normal pulleys or the 3d printed ones you mentioned? Also post a pic of how much the belt engage on the pulleys.

I’m using 72t 3dp pulleys, I’ll post a pic when I can
I’ll try digging around my parts bin and see if I still got a set of 72T pulleys, if I still have them then I can send them to you. Also can you show the belt tension from the top side?
Edit: Nvm, I don’t need to see the belt tension. Also, idk if that’s how you’re supposed to set of your belt tensioner…?

That would be sweet, metal pulleys would definitely be a step up from 3dp. Haha I know that’s not how I’m supposed to use them, I just couldn’t get the belts to go under it, I would need a new belt size. So instead of that, I just didn’t use it and moved the motors instead.

Maybe try getting longer belts and see if that helps. I will let you know if I can find the pulleys.

16t motor pulley
Yeah, maybe try longer belts to get the belt tensioner working properly. Still digging through my parts.

Yeah, I was just seeing if I could do anything else to make these work for now. All good no rush

Couldn’t find my 72T pulley set. If you need a cheap and durable set, MBS sells them for $20 per pulley, select the Rockstar II option for bolts and it should be good for your hubs since you have the Rockstar II.

That might be the reason your belts skip. Tensions seems fine, if anything a bit on the tight side.
If the teeth of the belts glide over the idler they might rattle and jump. By changing the direction you also increase the amount of teeth of the pulley in contact with the belt and thats what your looking for to distribute load.

In my head you definitely won the mountainboard category of BOTY. This build is so clean.

@Dnollie Are you still using the MakerxD100 on your build?
I was thinking of sending your bluetooth module pre-wired with the correct
connector for plug’n’play.
If you want to use your own connector, I can instruct on hooking it up.
Let me know, thanks,
Adam
