Just wondering if there’s some kind of rule of thumb or any suggestions anyone here can make on the right belt size for my DIY machine. My concern, (just because I worry about things), is that the 10mm wide GT2/2mm pitch belt I’m using is insufficient for the length of my axes, (1300 x 750ish). I’m using 59Ncm/84oz 2A NEMA 17 steppers which seem to be fine, and I’m not really seeing an issue with my belts at the moment, but I’m running conservative settings on speeds and accelerations because I don’t have a rigid frame yet. Since that’s what I’m working on I want to consider upgrading things I might have undersized previously as I progress through the re-build. When the frame is better and I can up the acceleration I want everything to be ready to go.
Can anyone tell me what they use in commercial systems of a similar size? I just looked up a Boss 3655 and they spec NEMA 34 motors, (other models just NEMA with no indication of size), but no belt information. That’s a pretty big motor so I’m guessing they have belts to suit. It also makes me think I should consider bigger motors, but I’m not trying to build a Boss. I am realizing just how badly my design sucks though.
