But when I change my laptop and try to connect, the Device Discovery Wizard can not find my machine. I has tried the Create Manually way but still cant connect.

Please help. Thank you so much.

I love homebuilt machines.

Which controller board and GRBL did you flash into it?
Does it use the common CH340 USB/ serial chip?
