6mm Timing Belt 3D Printer Belt White GT2 Open Synchronous Belt PU with Steel Core 10M

Very stiff belts, greatly improved 3D Print quality (less belt stretching during high accelerations). However, as with ALL steel corded GT2 belts, much higher belt tension force is required (some printers are too flimsy for this), and the steel cords break and fail MUCH faster than other conventional belts.. so expect to be replacing them often.

Worked perfectly

Seems to be holding up just fine on my Ender. Have been print with these belts for the last few months. No issue tighten up my prints.

Anyone who has left a good review for this product either hasn't used it long enough or is using it in an environment where a taunt belt isn't necessary. This belt worked great initially, but over time like others have pointed out, the "steel" banding in the belt gives and it will fail. It says its has a "steel core", however after several failed ones, I scraped a section with an xacto knife and it looks to be brass or maybe tinned brass to give it the look of steel. Definitely not worth wasting your money on.

This belt is used on my Butler Robotics, a longarming robotics system. The belt I replaced was 2 years old and getting worn. This belt works perfectly with the Butler. There is enough to make 2 belts for a 12 foot longarm frame.

I run this on a xcarve router cnc. The belts last and do not stretch, as a result the trend will wear out. I will use these any day over the regular fiber belts.

These are probably good belts in most situations. If you are looking for a belt to use on some CoreXY printers (Such as an ender 5 plus being converted to a mercury 1) these might give you trouble. The Steel core is appealing at first, however the CoreXY motion system has many loops and tight bends.these belts broke on the first day of usage right where it loops around the motor pully and 2 idlers. i did not have too mush pressure on these either.

My desktop CNC machine and my 3D printer both use the same size drive belt. I purchased this to replace a belt on my CNC machine and have the rest in reserve for when the need arises.I am very happy with the way the belt has been preforming since I changed it on the CNC. I would highly recommend this belt as a great replacement.

I used this for my Ender 3 when my belts finally stretched out way too much. They work well and after an adjustment an hour into the first print, they stayed the same tension and didn't stretch any further.

They are very strong flexible enough and made from non slip material. I was scared from other reviews but its grippy. I used mine to repair a broken belt on an Anycubic Predator. For a Delta printer as large as the Predator i think a stiffer less flex belt helps accuracy. Mine is printing smoother and finally after a month of fighting to get the auto level calibration to work on the stock setup, these belts gave it the accuracy required for a perfect first layer and a completely level mapping for auto calibration. I do think i had a defective stock belt as it just wouldnt hold tension even from stock setup. But these belts are what i needed. Came with enough to do 5 belts for the Predator so it has 2 backups on hand great product.

Great product, easy to install on my i3 mega. Doesn't seem to flex too much. It came long enough to do both belts x&y, with plenty excess for future repair or another printer. Plus looks great with my other (white) upgrades. Gives me the monochromatic look I want!Just make sure you're pulling evenly when attaching/fixing it to your application as it tends to twist. (If the perfect alignment matters to you). Printing better than before. Happy with my purchase.

The tight radius of the 20t gear shattered all of the wire core along the length of wear, giving the belt a 3 inch elastic zone that allows it to stretch and stretch and causing haywire to the displacements of the x and y axis.Probably good for other purposes, just not something that has relatively small gears.
