I just purchased the 9" mega quilter and Inspira frame for 1300............I keep getting skipped stitches, tried new needles...thread, tension............this morning I took the machine off the carriage, put on the regular foot and took off the darning plate.......BEAUTIFUL stitches! top and bottom tension is perfect.....put on the darning plate and changed to the darning foot.............every time I attempt free motion I get skipped stitches? Does anyone have any ideas or suggestions? I have been FMQ for a while on my domestic machine so am not new to FMQ ....thanks...
