Polyurethane-and-steel timing belts?

It's a question of what you want to use the belt for. All Belts are subject to stress as they run around the motor and idlers and gears and bend. They will get eaten as they are subject to friction ...

Which belt tension gauge do I need?

It's extremely unlikely that belt tension is actually your problem. I've never heard of anyone using a gauge to measure their belt tension. Typically you just pull your belt tight by hand so that it ...

Polyurethane-and-steel timing belts?

Belts come in several formulations. This page from McMaster-Carr lists several types of belts. The main materials (rubbers) are Neoprene and urethane, with fiberglass, Kevlar, and steel ...

Which belt tension gauge do I need?

You may not need to adjust the tension, but you may nevertheless want to measure the belt tension, at least to ensure it's not too tight: the shaft on stepper motor has limitations. For example, NEMA ...

Knotted String as Replacement for Toothed Belt

I’m going to recommend not using a fishing line with knots. Probably the biggest problem you’ll have using the fishing line with knots is if the knots are not perfectly spaced, movement along the X ...

Herringbone timing belt?

At a nearly microscopic level, the herringbone belt/gear combination will reduce the whoosh effect of a square profile cogged belt forcing itself into a matching profile pulley. Consider a well-sealed ...

How is my Prusa Mini damaging its X axis belt?

I followed up with Prusa on this recently (a few months later) and they confirmed that there were issues with some belts but that this has been fixed in production. To provide a better guarantee of ...

Can I lubricate the timing belts to prevent squeaking against pulleys?

The pulleys on nearly every 3D printer I've seen are held in place on the stepper motor shaft with a grub screw. A bit of rotation of the pulley should bring into view this screw, which will use a ...

What could have caused both belts becoming loose?

I figured it out. Long hours of printing ASA parts for my upcoming Voron Trident, in an enclosure, made printer parts softer and belts skipped on the teeth. I needed to glue and shim belt ends in ...

Tronxy X5S losing steps during print

I had the same issue with my X5S when I first got it assembled. Because it's CoreXY, if one pulley slips, you'll skip steps in the diagonal. Check both set screws on your pulleys for the X and Y.

Knotted String as Replacement for Toothed Belt

If you are using fishing line, it would perhaps work to wrap the line around the pully and fastening it to the pully (both ends), so that the line wraps around the pully. One side would play out from ...

Polyurethane-and-steel timing belts?

I have recently changed the standard belts on my Prusa MK3 for the aramid fiber reinforced E3D neoprene belts. Those belts are really tough and hard to cut even with a quality side cutter! They have a ...

CraftBot XL (CoreXY) part of x-axis movement resistance / high force required

I'm going to answer this myself, as I believe I have found the issue. It was purely a mechanical issue. On this particular model, the extruder motor rides just on top of / above the crossbar that the ...

Are resonances of belt driven carriage strongly direction dependent? Mitigations?

No, at least not to the extent the above result suggests. I had the idea to try rotating the piece 180° around the Z axis, and got nearly the same effect: low ringing in the middle segment, strong ...

Is it normal for belt tension to differ between sides of a CoreXY printer?

If you are referring to the tension in a single belt, but ar different positions, the tension is everywhere the same. It is one belt, the force/tension is the same in the belt. If the length of the ...

Specifications of Prusa Mini X-Axis Belt

To be sure you could measure the width and the tooth spacing (pitch). The most probable and used belt in 3D printers is the GT2 6 mm belt. The teeth are spaced 2 mm and the width is 6 mm.
