  • China Laser Aux Trigger Output K40 M2Nano Board

    Thanks for the information. You are the only person I can find on the Internet who knows anything about these controllers.I have an 80W Chinese laser cutter that I'm pretty sure has a dead M2 Nano. I accidentally knocked the USB connector, which broke a pin. I've replaced the connector, but it says "Laser is disconnected" I see that there is a component "WR1" connected across the inputs and to ground. The plastic has come away from the die, so I'm assuming that it's been through some sort of overload event, and has cooked the CH341A USB interface chip, which seems to be unobtainable from anyone around here. I've ordered another board from China, but I'm wondering whether it is tied to the dongle somehow. Do you know. Maybe I should have ordered a board and a dongle....

My assumption is that the dongle just controls access to Corel Laser. Do you know? Thanks in anticipation!RegardsDenis
