The problems just keep coming. I printed a new glass reinforced nylon pulley, now when I ride, there’s this weird bump sound/things that the pulley makes with the belt, I don’t know if I can get it to set in right, or if it’s more of a motor pulley problem.
Did you postprocess the pulley? Is it dimensionally accurate?

It’s the exact same design, except some extra support within. Just different filament.
Did you measure your final result to confirm? Made sure you’re not getting dimensional inaccuracies from artifacting, warping or layer lines?

Your left (right) belt isn’t aligned btw.
Please post pictures showing the sides of your pulley with the belt on. I want to see how much the belt is engaging with the pulley.
Like this but with no hands, just as it is installed.
Where is that model from?

I know, I just haven’t been able to get the blue loctite out, i think I put too much in the motor mounts set screws, any advice on that? I will send a picture when I get home.
What exactly do you mean by model?
It is the other side with the pulley problem btw
The model of your printed pulley

It’s a 3dp glass reinforced nylon, it’s 72t, 15mm wide,
It’s a custom design that me and my dad made.
Do you mind posting the model? Was the previous pulley also glass nylon? What happened with the old one?

The last one was PLA, as well as the other pulley, I only reprinted in Nylon bc I thought it would be stronger, and the previous pla one broke. Model as In file?

Blue loctite doesn’t generally need much to get free but heat helps free up loctite in general. Just be careful of surrounding parts when heating with a torch/heatgun

Ya post the STL or STEP file
Or f3d or w/e

Also, what’s up with this? It feels like there is something In there, it gets caught when it moves reverse.?

Oof that could be bad. You need to take the motor off, remove the circlip holding it in, pull the can off the base, remove the debris (which is hopefully not a magnet breaking off) and put it back together.
You might need to tap the shaft with a mallet if it’s stuck, be careful of the fragile sensor on top of the stator, be careful letting the can back down not to let it slam down too much from the pull and careful not to get your finger caught when the magnets snap the can down it hurts.
*and screw the motor back into the mount if it’s difficult to get the can off

Are you missing a nut on the bottom in that picture? That might let the pulley be loose enough to knock back and forth

Fuck.
Chances are it’s fine you aren’t running huge amounts of torque for those big motors, getting it apart is a bit of work but nothing really difficult.
It sucks I know I snapped a magnet in a 6396 recently so I had to take it apart and a few days later pulled a magnet shard off inside a 63100 and had to take that apart too.
Maybe you could keeping going with it like that, I used that 6396 with a completely broken off magnet for a while it just took some more amps
And that pulley reminds me I need to get your metal ones together and shipped asap.
