HAve a Black and White K40 from Redsail. M2 nano
The M2 Nano board finally quit working and I purchased the Cohesion 3D board with the GLCD screen.
The screen is on and darker screen in the center but no Data (Blank Screen). Install and posted a problem covid and could not get any help since they were short handed… It started working the other day for about a week but since quit again. I would really like some help getting it working.
I only have the Laser fire and Laser Ground wired. The limit switches. the the x and y motors.
Installed per all the documentation. Checked and rechecked. still not data or interface.
Need some suggestions. Never worked but about a week since it was brand new.
