K40 Laser Control Panel with OLED Display Fixed

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4352722.

This is the corrected code for the 128x64 OLED display to be without scan lines for better viewing. You need to correct the lines in the library "adafruit_ssd1306.h" as shown in the photo.

Thanks to David Deloera for the good idea!
