yes. I follow all the steps. install the driver… but stil have the same issue. I had to restart the pc several times . also days and sudenly connects . but just for few minutes . because if I wait with the engraver connected. it said that the engraver is busy and dont let me do anything else
I also use Win 10 Pro 64 but I don’t have this problem.
I hope someone with more knowledge than me can help you.
Meanwhile, in the “laser” window where the COM port appears, have you tried changing the port and seeing if it already connects?
