Sorry, still no weave option. That's a lot more code than I have time to do, considering my current work. IIRC, you probably are not getting a preview because maximum_diameter (@line 52) limits the belt diameter to something that would fit on the printbed. I suggest you print a spiral belt, join the ends, and see if that works for you.

Also .. (sorry - newbie OpenSCAD user) .. I've tried: module belting( print_layout = "loop_inner", tooth_profile = "GT2_5mm", belt_length = 1580, belting_width = 6, max_diameter = maximum_diameter) { and module belting( print_layout = "loop_inner", tooth_profile = "GT2_5mm", tooth_count = undef, belt_length = 1580, belting_width = 6, backing_thickness = undef, max_diameter = maximum_diameter) { .. and neither give me a 'preview' ... what should I be using there to get a GT2 belt 6mm wide 1580mm long?

I downloaded the new SCAD - but I don't see an option to weave the loop inside it's self to print a longer closed loop on a bed .. is there one? if so, which would I pick?

Excellent - thank you .. yeah, I was going to try with a SainSmart Flex, or SemiFlex - those are still flexible, but don't have the 'stretch' that NinjaFlex has ... I will certainly try your new OpenSCAD file. I did figure out a way to splice my 'regular' GT2 belt - that looks like it will work, but I'd really like to try to print out my own. Thank you for your response!

Hey goldentuna1200, I looked at doing that awhile back, but found that the tight bend required for reversing direction left the belt too kinked for my needs. I was using nylon back then. It may not be as bad with TPU. In any case, I just uploaded a newer version of the OpenSCAD file, with more belt options.

Is there anyway to make a closed loop belt weave or spiral to fit a longer belt on a print bed area? I need a closed belt of 1580mm, and using this it gives me a belt diameter of 508mm. thanks for your work on this.
