    Is a GT3 6mm belt strong enough ?

    I'm building a 1.6M by 1.6M CO2 laser cutter using 20X40 V-slots. I'm going to use Nema 23 2.8a motors. I want to mount the belt on the motor at one end and an idler pulley on the other end but I'm worried that with it being so long the belt will sag and not provide enough tension.

    Does anyone have experience with large builds that can offer some advice?
