Hey everyone! Been a while since I posted but I just installed a new Ruida Controller model 6442G into my Morn L570 laser. After setting a few parameters I finally got it working smoothly! The question I have is, this controller has a display screen that shows the graphic that you are working with. If I send a letter K for example to cut, it shows the path of the laser and the K shows on the small display. However, if I send the K to scan, the display just shows a red cursor moving back and forth, and doesn't show the graphic image of the K being filled it. Is this normal? I thought it would show the graphic anytime the laser fired, so you could see the image develop. Is there a setting I am missing in the menu, or doesn't it just show something if you send a "Cut" file? Thanks and hope everyone had a great Christmas!
