Hi,
I have a Ultimaker 2+ which I love. I have had some success with uploading a version of Marlin to it so that I can change the Serial Port to #2 and baud rate so that I can attach an ESP to J22 (Serial).
This worked well, as I can now see GCODE output etc, but the firmware I am using seems to run the feeder in reverse (ie material is pushed out of the printer instead of in)
I was a bit worried that I was endangering the printer running with this firmware. Has any one got any experience of this, or could point me in the direction of settings I could change?
What I would really like is just the bog standard firmware that I can adjust the two settings in, but there seems to be a whole minefield of different options now. Tinker firmware?
Thanks for your time.
Dan
