      E3d sell the gates belts on there website now they aren't advertised as gates they are just advertised as upgrade gt2 belts. I recently contacted gates about there polychain gt2 belts and they advised me that they have been replaced by polychain carbon gt2 that use carbon fibres in the core.

        I've used these. Might be able to get the length you need.

          @monster-delta Damn, I want those, but looking at the catalog they start at 8mm so that a means a total re-work of my drive system.

              @3dmntbighker Ask them if you order more 2m if it will be one pice. As far I know it should be.

                  Well this is what they look like up close:

                  They look nice and they feel nice although I'd echo what Mark Rehorst (Digital_Dentist) on reprap says they don't seem to make much difference to print quality. I am running 3 lengths on my delta at around 2 meters per belt, so it's a distance over which stretch/elasticity should be apparent in substandard belts, but they seem to work about as well as chinese no-name fibre reinforced belts. I was able to discern a difference with steel-cored belts until they progressively failed resulting in weird, hard to diagnose skew.

                  I doubt this helps...

                    They look just like mine.

                    I found that my cheap Chinese belts had a bit of a curve to the edges and would ride up and down the pulleys a bit. The gates belts are dead flat and don't travel at all. They seem more flexible and don't feel like they have as much give.

                    I might have just had really crappy belts.

                      Anyone already found Gates Belts longer than 2m? Would really like to give them a try but I'd need at least 2,4m each...
