I have tried both versions of the firmware. I have figured out what is happening. Once I took the belts off of my Y drives I could see more what is happening. The second Y motor being output to E1 will only spin in the same direction. So if you tell it to move in the + direction it spins counter clockwise and if you tell it to move in the - direction it still only moves in a counter clockwise motion. It doesn't spin clockwise. It is still treating E1 as an extruder instead of a mirrored motor output.
How do I fix it???
"Why not wire it up more traditional. Two motors wired to Y axis."
Not enough power, my steppers need 1.5 A per axis.
"Two motors wired into z axis (it has two connectors) and swap Z and Y axis in firmware"
Not sure I can but might be possible. I am not sure exacly how.
"Why do you need the z axis driver if you are not using a motor?"
I will be doing full 8-bit laser engraving with picengrave. Picengrave takes your picture and converts the lightness and darkness and outputs it to the Z axis. It goes through a custom dac (digital variable resistor) that converts it to an analog signal which goes to the analog input on your laser driver.
"Z commands can go directly out to laser to PWM the power output."
I don't plan on using PWM pretty much ever. PWM is hard on your laser diodes and reduces their life span.
