To the gentleman asking about quilting machines. Hi, My name is Larry. I developed a quilting machine back in 2007, using a 4 port parallel controller card from Rockcliff Machine, (no longer selling that board). I used two Nema 17 steppers for movement, a Husqvarna quilting machine (manual), a needle controller that sensed the movement of the carriage using two Encoders attached to the needle controller. I designed what I called "the CNC Quilter", to be controlled by Mach3. The operation of the quilter was extremely easy tgo use, and my wife produced more than 40 different quilts of varying sizes. I now have the machine controlled by a BitSensor USB card sold by BuildYourCnc.com. They are located down in Florida. I must be honest, this card is not very good, as it is very hard to setup. I have worked out the settings in Ports and Pins that control the card, but it took much experimentation. As far as buttons on the screens, yes that can be done. I designed a whole new screen for the quilter, that is just for quilting. It has a problem that I believe is related to the USB controller. The OFFLINE button refuses to work, and is, for me, definitely needed for proper alignment of the needle on the fabric. If there is more info that you need, I can be reached via email at Opa3times@gmail.com.
