You might have some success with alloy 910. I’ve been running a gear in my Kaly gear drive for a bit now (only about 100-150 miles so far) and it still looks like new.

Not to mention the cost of printing that filament would exceed the cost of getting it cut out of most common thicccc metals
For some reason I’m able to still turn the pulley (just) by hand even when the eccentric nut is in the tightest position
Is this ok?
That’s just grease, right ? For a second they look like they’d melted. If you’ve had luck using it for gears then that’s actually quite promising
Nylon on its own (no fiber) is not all that stiff compared to PETG or PLA. That’s what makes it tough - It bends instead of snapping.
That also makes it less desirable as a motor mount tough, since you need something stiff to withstand the forces being put on it.
If I had to pick a possible candidate I would go with either a fiber-reinforced nylon (either CF or GF), or maybe PolyMaker PolyMide CoPA, which is supposed to be crazy strong.
Either way you’ll be spending $$ on filament and a printer that can print it, for a result that, in the best possible case, is still just “meh” compared to a cheap aluminum mount.
It’ll have to be significantly thicker in just about every dimension too, which may cause interference with other things as well.
Don’t get me wrong, I know the itch. When you’ve got a hammer, every problem looks like a nail.

Yeah, I know your right and I prob won’t bother. Thanks for the explanation

What about a half printed solution, where you print out the general downsized structure, but then layer fiberglass or carbon fiber over it? I’ve always been curious to try that, but I’ve only ever covered with just epoxy, and not any cloth which should be stronger.

Definitely this…

I mean, if you’re going to go to that length, why not just 3d print a mold and make the mount entirely out of the composite?

can someone help
my eccentric nut is at the tightest possible solution and still the pulleys can just turn themselves (with a lot of force) is there something wrong
Please clarify. Which pulleys? Under what force?
It is almost always better to be more specific.

x axis
the bearings for the carraige
when turning the top ones by hand they spin rather then moving the belt (they are very hard to turn though)
Pictures or video, please?

yeah in a lesson give me a bit
also got something printing atm
From next time please make sure to include all details, in one post, that might possibly help in solving the problem. Otherwise it clutters the thread. And also makes people unwilling to help.

^^ for real lol
Especially when it sounds like you’re contradicting yourself

sorry yeah your right
also @MysticalDork here you are
the bearings on the x axis are to loose even with the eccentric nut in the tightest position
Yes, that.
It is almost always better to write out a big info dump and give too much information, than to have to go back and forth a dozen times with one piece of info at a time.
Just put it all out there in one pile, where it can be seen.

I wouldn’t call that loose. Without being able to physically grab the hotend and feel it for myself, I would guess that is fine.
Those aren’t drive wheels: they don’t need to have perfect traction, since they are just there to follow the rail.
You just need them snug enough that the hot end (the nozzle specifically) isn’t free to wobble around, or otherwise move other than along the X axis.
As long as that’s the case, you’re good.
In fact, if they’re too tight, you can end up with flat spots from the plastic compressing over time when the printer isn’t moving, which can result in some minor artifacts.
See? big info dump. Probably too much, but it gets the important points across, even if you’re not sure which ones those are.

thanks mate
seems good just slight squeaking during my print but the print itself came out amazing so guess all is good
