Gsender doesn't recognize port

When using gsender, in the milling mode, it connected to Com3 port just fine. I installed my laser, and now gsender doesn’t recognize that com port. Very frustrating. And ideas?

You could try putting LightBurn on trial. It knows about lasers and is very well written. I would be surprised if it did not work well. As a side note, I use LightBurn and I have to run a Macro when moving from CNC to Laser and vice versa.

CNC to Laser Macro:
G10 L2 P1 X-459 Y-415

Laser to CNC Macro:
G10 L2 P1 X0 Y0
