First time user, my computer is connected to laser via usb cable, put in first design and press start button and I get a message saying there is a problem sending data or laser is busy or paused.
What am I missing? Thanks in advance.
In console window type in $$ then enter and paste output, please.
What do you mean by type $$ on the console window if you are using your laptop
Here.
What com port are you using?

Possibly an easy thing to try is to replace the USB cable with a known high quality cable fitted with a ferrite bead. While its always best to start with a systematic fault finding process, starting with the $$ output as above, this can be a quick way of eliminating one possibility - the cheap usb cables supplied with hobby machines are often less than ideal.
