As the description states, I am unable to "Play" the file from the external SD Card slot when I am using the Dual Head 1.75mm Toolhead. I set up my GCodes to print from only one extruder as a test to see if my electronics controller board is the reason my Single Toolhead won't print. That is a different issue that needs addressing, so testing it with another toolhead seemed logical. Attached you will find a copy of the gcodes I used so you can try to replicate the problem.
I prepare the printer for printing.
Insert the SD card into the slot behind the LCD.
Select the file to "Play".
Nothing happens. The menu says Play (as in Play a file) when it should be printing; not to mention the screen should say "Abort" instead of "Play".
What I tried:
I tried to regenerate gcodes.
Reformatted the internal card and flashed it with the dual head configs/firmwares.
Removed the Ext SD Card and flashed it with a new file.
This file is a modification to the second file, below. It is meant to test PETG from 250C down to 240C in 2C decrements every 10cm.
