[0001] The present application relates to the technical field of laser engraving machines, and in particular to a control system of a laser engraving machine. Background Art

[0002] Laser engraving technology is widely used in engraving various materials due to its high precision and high efficiency. Existing laser engraving machines use industrial-grade chips, such as FPGA (Field Programmable Gate Array) or DSP (Digital Signal Processing) to control two galvanometers (two motors).

[0003] However, the cost of existing industrial-grade chips is very high, which makes the cost investment of laser engraving machines relatively high. If low-cost MCU chips are directly used to replace industrial-grade chips, although the investment cost of laser engraving machines can be reduced, it will also greatly affect the response speed of laser control.
