If you do all three, press Reset between each and repeat initial steps. When you’re done, post the result in my comments! The winner(s) will earn a lifetime of respect by yours truly.
You could always work your way around it using this mathematical expression of the encryption: E = PRMLUL-1 M-1 R-1 P-1
Where
P = Denotation of the plugboard transformation
R = Action if Right rotor
M = Action of Middle rotor
L = Action of Left rotor
U = Denotation of the reflector
