Do you know for a fact that E1 works and E0 doesnt, or is that just a test.
If you are sure that E1 works while E0 does not, you can go in pins.h and see which pins does it use for E0 and E1, and just swap them to each other. And with this change, the new E0 will be physically considered the old E1, and ofc, vice-versa.
