① The sequin status button must be pressed in advance when sequins are selected: to sequins, the sequin status button must be pressed. However, if the sequins are to be put down at the next needle drop point, and the sequin status button is pressed from this needle drop point, this will not work. Because the sequin placement head on the sequin machine is driven by an air compressor, if there is air leakage or insufficient air flow, the sequin placement head will not be in place in time, which will make the placement of sequins unsuccessful. Therefore, in order to avoid this situation, the current solution is to lower the sequin placement head when 50-100 stitches are to be placed before the sequin.

②The choice of raising or not raising the sequin head: In the usual card making, the sequins are not printed after the flat embroidery at one time, and the flat embroidery is not repeated after the sequins are printed, but interspersed according to the specific situation. If the sequins are finished, a flat embroidery is required, and then sequins are still to be printed. Then, in the process of flat embroidery in the middle, whether the sequin head is lifted or not is a question that needs to be carefully considered. If there are not many stitches in the middle flat embroidery, generally no more than 1K stitches at most, so don't lift the sequin head. If there are more needles in the middle, it is better to raise the sequin head. The former is not lifted because the time consumption of raising the sequin head and putting down the sequin head is considered to be a larger proportion than the time spent on embroidery. For the latter, it is necessary to lift it up because considering that the number of needles is too large, the thread will inevitably be broken, and if the sequin head is not lifted, threading will be more troublesome.

③Lock the needle, close the coordination between the sequin head and the thread trimming device: the sequin machine must lock the needle, because the stitch to put the sequin is at least a 3.7mm flat needle. Therefore, if the lock needle is not strong, it will directly cause the film to fall. Generally use short stitch flat stitches to lock the stitches. If you do not use sequins, or if you need to do flat embroidery for a period of time, then you must raise the sequin head, which requires special attention to the relationship between lifting the sequins and trimming. The general principle is that the sequin head must be raised before cutting the thread. Otherwise, the thread trimming device will touch the sequin head. Moreover, because the thread trimming device is driven by the spindle motor, and the sequin head is driven by airflow, if you want to trim the thread, it is best to lift the sequin head at 50-100 stitches before the thread is trimmed.
