Regarding first order, it took a while. Of course I’m in the Seattle area where there are a lot of folks with 3D printers, so it’s mostly a matter of how close your customers are. Also, what equipment you have. One of my customers has his own 3D printer but uses my service because his own printer simply won’t do the job. I expect he’ll eventually just upgrade printers and won’t need my service any more.
Regarding warping, I’ve had much, much less problems with PLA than with ABS. Heated bed makes more difference than hair-spray for me. And orientation of the print. I also found that using a raft helps too.
My first order was two months after setting up my hub, mainly I think because my prices were very high. I reccommend adding pictues of prints and your setup onto your hub for more attention.
As for warping PLA warps a lot less than ABS. I use a heated bed at 110c and a glue stick. I found that a lot better as you can concentrate the stickiness to one area. I sometimes have to use a raft for small objects though. It’s all about trial and error with your printer!
