FAQ:
Q: Input not matching our unit?
A: Our module interface is an XH 2.54 3-pin connector. Please refer to the product images for the specific layout before purchase.If you are unsure whether you can connect, please cont/act us for assistance.
Q: When the laser module is connected, the fan runs but the laser is not on.
Solution 1: Please check if the signal port (PWM) is well-matched. If you are not sure which port on the main board is "PWM", please check with the main board seller.
Solution 2: Power off the engraving machine; Disconnect the cable of our laser module from the main board; Reconnect the laser head to the main board and restart your engraving machine.
Q: Is this laser module compatible with CNC machines?
A: It can be used with a CNC machine attached. But the size does not fit the original bracket of the cnc machine, you need to make or buy the bracket.
