Art; Just received my opto board, using rev 2 Pokey CNC57 board, their info shows original layout without any change to the pwm pin 7 on test I/O connector in their pdf? Do I use pin 7 (default) from the Test IO connector, or you think pin 14 like you mentioned is the way to go for laser power control?ArtF wrote: One more piece of data, ( because threads such as this exist for years and many tend to read them for info..)
The following photo shows the Pokeys57 revision 2 changed the PWM location on the TestIO connector. As indicated by the arrow..
Art
