Quilting Knowledge Series (Part 1)

What to do when the chain stitch quilting machine fails to pick up the thread?

First, check whether the upper and lower threads are correctly threaded and if the thread tension is appropriate. Then, push up the light axis and check if the needle and hook are in the correct position, approximately two millimeters apart.

If the pattern jumping stitch is not picking up the thread, you can adjust the parameters on the computerized control interface to increase the thread length parameter, but be careful not to increase it too much.

What to do when the quilting machine produces imperfect circles?

First, reduce the stitch length appropriately, ideally between 4.8 and 5.2. Then, set the backstitch to 4 and slow down the speed. This should result in a nicely formed small circle.

How to quilt a standard and even pattern?

First, identify the root cause of the problem. Uneven patterns can be related to the thickness of the sponge. If the base material is too thin, it can also cause pattern distortion, uneven sizes, and disproportion. Adjust parameters according to different patterns and material thicknesses.

For continuous patterns, if there is horizontal overlapping, reduce the x-axis parameter; if there is vertical overlapping, reduce the y-axis parameter. Conversely, if horizontal and vertical lines are separated, increase the x and y parameters accordingly.

For jumping patterns, adjust the GX and GY parameters. When quilting diamonds, if the diagonal separation is too wide, increase the diagonal pull parameter; if the diamond diagonals intersect, reduce the diagonal pull parameter.
