If you feel that you are having trouble getting accuracy in your computer guided longarm quilting system, you will first need to identify whether it is the machine, the fabric, or the design. Take a close look at where the design points and lines should meet and where the path backstitches on the designs you have been stitching. Are the design points meeting properly and is the backstitching accurate?
If not, you may want to run a stitch-out of our Alignment Precision Test design. We have designed it specifically with spirals, curves, lines, and corners using accurate sharp "kissing" points, and backstitching paths to help you see if your system is working properly. It may help you troubleshoot the problem. See our Trouble Shooting Tips below.
How to use the Alignment Precision Test
Trouble Shooting Tips
- Check to make sure your take-up, belly-bar, and load rollers are all parallel to each other by measuring the distance between them at both ends of your frame. Even the slightest uneven spread at one end will be magnified at the other end.
- Check the settings in the software that runs your system. If you have a setting in the stitch controls for "keep angles," set it to the highest position to get the sharpest points.
- Consider the thread tension. If the points and angels are rounding with an eyelash effect. Start by checking your bobbin. The bobbin tension should be set so that when you drop the bobbin filled case from your hand while holding the end of the thread, it should smoothly "spider" it's way to the floor. If it doesn't, adjust it with minute adjustment until it does. Once this is set correctly, other adjustments are made to the upper thread until the stitch meets properly in the batting layer.
If the eyelash effect is on the top side of the quilt, try loosening the upper thread tension. If the eyelash effect is on the bottom side, then try tightening your upper thread tension.
- Take a critical look at your previously finished projects and compare them to the original design files that were used. Was there a specific point in time where the stitched designs on your quilts went from good to not-so-good? Ask yourself, "Did I make a change to the machine, frame, or change a setting in the quilting software that drives my machine which may have altered the stitching quality?"
- Or as I have seen happen, has your machine been stitching with the misalignment all along? One quilter I know, discovered when taking a critical look at their previous quilts, that all of their quilting had been victim to alignment trouble from day one of the machine's set up. But they didn't realize it. Had they run the precision test at the start, it would have been obvious. It turned out that there was a calibration step that the set technician had missed during the installation and setup of their machine.
