If the quilting embroidery machine is embroidering thick materials, the needle bar can be lowered to 200;ordm;, so that most stitches will not skip stitches when hooking. Look for the source of interference and check whether the switching power supply (5V and 12V) and the rack have a DC voltage greater than 2V. Note that when the thread Wholesale Multifunction Mixed Embroidery Machine Manufacturers trimming lever pin enters the trimming cam groove, there must be a gap between the pins in the groove to prevent the pin from jamming in the groove when trimming the thread. If the data is consistent but the origin of the embroidery frame is incorrect, the stepping drive system is faulty. It can only measure relative values, not absolute values.
The specific method: Use the dial indicator measuring rod against the plastic body of the lower section of the drive block, turn the eccentric cam in the forward and reverse directions with your hand, and repeatedly see the indicator of the dial indicator pointing to the bottom dead center of the slider, tighten the eccentric cam tightly. 1 Cam synchronization method of metering When the embroidery machine is repaired, it will inevitably encounter cam synchronization metering.
Set screws, according to the method can adjust other heads. Troubleshoot the circuit and replace the faulty stepper driver. The principle of the embroidery electromechanical magnet thread trimming mechanism is the same as that of the computer lockstitch sewing machine. The drive power transformer or stepper motor is faulty. If there is, eliminate current leakage.Computerized embroidery machine maintenance: position running, thread trimming, table printing. Re-enter a pattern.
The stepping signal line is interfered, causing position shift. If the data is inconsistent, the main control board is faulty. How to correctly print the meter and determine the degree of hooking time is very important. Dial indicator is a high-precision measuring tool. 2 Maintenance of the thread trimming part The thread trimming angle of the embroidery machine is between 285;ordm;～286;ordm;, some can set the trimming action angle and the thread trimming length hooking ratio.
