Can someone else watch the wheels when you do a curve? I have this machine and it LOVES to sew straight lines, but on curves I need to go much slower. The wheels don't seem to engage well on curves. With practice I got the hang of it, but can't seem to do small, fine work like micro stippling. Frame seem too stiff for that. I rarely use my Qbot, the only reason I have it is it came bundled with the machine.
