CR-10 Not Printing
Repetier indicates connected with printer. After slicing and pressing print, nothing happens - no heat, no fan, no action. Is there a setting I missed? Should the printer controller be off or on?
Check in log if you get any responses from your firmware. E.g. an answer on M114, M115 or M119. If not you most probably have used a wrong baud rate.
Error message = "OpenGL"
What does that mean?
OpenGL is the 3d driver for the 3d view. Do you see it? That should have nothing to do with firmware connection.
