It will work with cordura for sure, until you need to punch through 4 layers and webbing or more which isn't often and it still might do fine. Silnylon in particular is very slick and difficult to work with though you should be able to with that machine it's not going to be easy, cuben is similar but not quite as slick and works totally different so you will probably be okay getting it to feed.

. I know for my machines, the 1.1 silpoly was somewhat difficult. That being said, I think it was about the learning curve for me. As in, how does it best feed going through it. It was interesting as I went along because I ended up feeding it through the machine in different ways that ended with more of a natural/easy feel. The machines were more than capable of sewing it fine, I just had to figure out for myself how to best help the machine with my hands. I generally ended up with one hand behind the presser foot and one in front, holding the material and giving the feed dogs an “assist”. In the end, it worked out just fine and the projects have held up to use so far. 
. Can’t wait to see what this will do.
