What length i need for x axis ? Guy from ebay only got 900mm length

I think that might be too small, or extremely close. I think you want at least 1000mm.

Crap and no one got that in europe how i see it ,only china but on same page it say g2 and t2,5 fir same belt

12

As I understand it G2 and T2.5 actually have different teeth profiles. While you could probably use a t2.5 you might see more backlash compared to a G2.

13

So only mxl 6mm with 2mm teeth ?
But where to find it ?
Grr

There are not thaf many toothshapes in 2mm.
T2,5 is the smallest TBelt my sources have available.
AT3 upwards
HDP 5 upwards.

If you are targeting GT2 ( not sure as I don’t have such a lasercutter ) and open belt situation, so to be closed on or by the carrier you could check Amazon and get 6m pieces for a few bucks.
If your Firmware is
Flexible you also could think about changing the pulleys for GT2 use there are also different sizes / toothcounts available… To improve availability of belts for your system…

Hope that a link to a source is ok here and not taken as advertizing…

Just another hit rather short closed belts but MXL style… MXL does not 100% 2mm pitch as the seller tells in the short spec…
