Ortur h10 20 wat

i have ortur h10 20 watt, the laser stops in the middle of an engraving. it will engrave about half of the image or design and just completely stop nothing is showing up on the console. no errors. can someone help me on this.

In most cases a connection issue. Change USB cable, use a short one, remove electrical disturbances.

Console “Port failed to open-already in use?”

Check the device manager which COM port the laser got assigned to. Then select the correct one in laser window.
