Laser - Ramps - ARGH!!!!

Mostly Printed CNC - MPCNC Troubleshooting
1

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:

#ifndef RAMPS_D9_PIN
#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.

Help?

You are trying to use arduino 1.8.5. You have to use 1.9 or higher. Details on the firmware page.

Bet you had a nickle for every time you had to say that. Thanks. I’ll buy you a bear at the MRRF next year. Was I correct with changing the code in thepins_RAMPS.h?

The previous post just before this reply was the exact same…so we are at $0.10…can’t wait. I will bring a cooler.
