Just installed the Cohesion 3d Board and not the Graphic LCD Control Panel. The laser is working good but the Graphic display is not working. I figured out I had to put the sim card in the Cohesion board before the laser would work. not documentation said to do that. the display backlight is on but no numbers. it also will beep. but nothing else.
Sorry I am new and can not upload pictures.
I have the X and Y cables attached.Working good
I have the X and Y end stop cables attached. Working good.
I have a Laser Fire and Laser GND from the LPSU attached. Working good.
The Graphic Display back light is on and the screen has a darker area in the middle like it is working but no visible data. Adjusted the contrast but no data.
Other than that the laser is working good in Lightburn.
