Woodworking engraving machine lost step is an uncommon but very annoying problem, often appear lost step phenomenon of woodworking engraving machine light need to re carving materials, heavy need to find a new material for processing. The reason for the problem of losing step is not that we can't find it out and can't repair it. It's helpless. How can we prevent the problem of losing step in peacetime. Xiaobian today will take you to see the analysis of the lost step fault. Next, we will follow Moyuan CNC to understand the reason why woodworking engraving machine lost step!

丟步十有八九是機械阻力變大造成的，檢查軸承如果是好的話，就清洗絲桿后再上新黃油。滑塊等都要清洗后重新上新油。如果還不行看看步進電機引線接觸是否良好。

Nine times out of ten, the lost step is caused by the increased mechanical resistance. If the bearing is good, clean the screw rod and then apply new grease. Clean the sliding block and add new oil. If not, see if the stepper motor lead contact is good.

雕刻機在刻圓時，重復運行多次程序，出現不同心，刀路逐漸往圓內走，感覺圓越畫越小。或者刻字時，刻出字的比例和電腦程序的比例不一樣，有點壓縮的味道。這就說明雕刻機丟步了。

When engraving a circle, the engraving machine repeatedly runs the program for many times, resulting in different concentricity. The knife path gradually moves to the inside of the circle, and the smaller the circle is. Or when engraving, the proportion of engraving is different from that of computer program, which is a bit compressed. This means that the engraving machine is out of step.

1、檢查一下機器附近是否有干擾源，比如高壓線，變壓器設備等干擾設備。

1. Check whether there are interference sources near the machine, such as high-voltage lines, transformer equipment and other interference equipment.

2、電源不穩定也會引起該問題，更換電原或增加穩壓器。

2. Unstable power supply can also cause the problem, replace the original power supply or increase the voltage regulator.

3、看一下加工參數里面的加工速度是否超出機器的極限速度，請更改成合適的雕刻速度。

3. First of all, let's see if the processing speed in the processing parameters exceeds the limit speed of the machine. Please change it to an appropriate engraving speed.

4、機械上可能是聯軸器松動，及時緊固松動的聯軸器。

4. Mechanically, the coupling may be loose. Tighten the loose coupling in time.

5、雕刻機驅動器或者驅動芯片損壞。如雕刻機的x、y、z軸步進電機是由專用的芯片驅動，如果芯片損壞或者散熱不好就會導致步進電機丟步。驅動芯片穩定超過105度就會自動斷電保護，等溫度降低后電流又會恢復。送修驅動器、更換驅動器或者加裝散熱風扇即可解決此問題。

5. The driver or driver chip of engraving machine is damaged. For example, the X, y, z-axis stepper motor of engraving machine is driven by a special chip. If the chip is damaged or the heat dissipation is not good, the stepper motor will lose its step. If the driver chip is stable beyond 105 degrees, the power will be cut off automatically, and the current will recover when the temperature is reduced. The problem can be solved by repairing the drive, replacing the drive or installing a cooling fan.
