3D printer firmware

Hi. I hope someone here can help me figure this out. I have a 3d tevo Tarantula printer. I have been going nuts trying to get the firmware to work. I’ve downloaded the file from tevo, but I keep getting error codes. Can anyone help me before I go out on a drinking spree.

You are much more likely to get helpful information on the RepRap Forum where they specialize in 3D printing.

This Forum is really for helping people write their own Arduino programs.
