I haven't gotten to try mine, but did you try putting in your coordinates again, using the far top right and the right one for the left? If you are an experienced used, I'm sure you did, but just thought I'd ask.
I just spent 2 days in Cincinnati, OH, taking classes with Pam Clarke--she is great. She does really good work and teaches it is a way you understand and with techniques that "should" be easy to follow. Since I'm learning both free motion and the Qbot, I hope I'll be able to put it all to use.
Thanks for the hint on the cables--we don't have a Sportsman's Warehouse in Richmond, but we do in Lexington, which is only about 30 minutes from me. We do have a Dunham's I may check tomorrow and see if they have these. I may have to ask you how he did his ends to make them stay looped but I'll try anything!
