The Ruida644XG is my machine. The GRBL 1.1 is what came up with the controller pictured.
I didn’t even notice the 10mmx10mm size settings there when I tested it.
The meeting was for a demo machine that an importer had. They didn’t clean it off, there was wiring twisted together and covered in packing tape (!), and it was in generally in abused shape. The meeting was a nightmare as well- there was a ‘tech’ to demonstrate the machine for me, and a translator who knew nothing about the machine at all. I got frustrated when they couldn’t get it or their PC started, and asked if I could just plug my laptop in. Luckily, Lightburn found the machine right away and I was able to test it.
I declined on the demo machine, but they’re offering a new machine for a slight discount… but this struck me as a weird red flag. I think I’m going to listen to my gut…
