It's a time consuming process, but worth every second of it IMO.

I was thinking about ask Monport for its specs the other day. Just emailed you. thanks

Thank you. Yes, a Gweike Cloud owner has confirmed EZ Red Dot works perfectly with his Gweike. Monport Onyx is untested, so I would say no for now. Which machine do you have?

It's a red dot laser for Omtech Polar. Longer version ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XRZqxm6NsGw.html or maker10.com/product/m10-ez-red-dot-laser-for-omtech-polar-350/

When your computer is connected to Polar via USB, you can send job from Lightburn using the "Send" button instead of "Start". The job will be waiting for you in the Control Panel's memory, it won't start until you press the "Start/Pause" button on the Control Panel.
