Okay. I have been wanting a laser for a while so I broke down and bought an E-bay special to “get my feet wet”. I have the laser, designed and printed a mount for it, and need to update the firmware to run pin 44 for the TTL thingy. Downloaded the newest firmware…made the change (I think…more in a second on that), and tried to upload to a spare Mega 2560. Insert gong show “bong” here.
Okay…changing pin 9 (fan) to pin 44. Going through the MPCNC-laser-add-on-walk-through.pdf section b has changed.(?) I made the change in pins_RAMPS.h as follows:
#define RAMPS_D9_PIN 44 // changed to 44 from 9
I don’t know if that was the correct move or not…please someone correct me if I am wrong.
After changing I tried to upload. I get an error (see attached file). I have tried the old u8glib and the new u8glib (I recall having to use the old one when I previously flashed the Mega back in December). Didn’t help. I’m stuck…and frustrated.
