Got this assembled on the table last night. Z moves backwards, will fix that in firmware. Y moves. X needs the belts installed.

Easier to just flip the connector on the control board than to do custom software tweaks.
Yeah nah.
Board is sandwiched between the two acrylic plates. The board I used had a set of 4x2.54mm pitch holes for each of the stepper drivers so I fitted connectors that have a positive lock. (I found the molex ones fall out.)
Oh yeah. Had a hell of a time getting the code to work. My repo is now https://github.com/tortfeaser/Marlin-for-V1E-LowRider-CNC
My problem was that I was using the bugfix-2.0.x branch, which requires the v1.9 Arduino beta IDE, which has a conniption if there is a comment after a pin definition. So I had to remove all the comments after pin definitions in pins_RAMPS.h to accommodate the dual stepper drivers on X and Z.
Also I had changed the pin definitions for the microstepping pins in pins_MKS_BASE.h to add reference to E2 (like you must do for the stepper driver pins). But that was not correct. While the reference for the second Z motor is to the E2 driver, the reference for Z microstepping pins doesn’t change from E1 to E2.
The code compare is now at https://github.com/MarlinFirmware/Marlin/compare/bugfix-2.0.x...tortfeaser:LowriderCNC
1.8.6 hourly seems to work way better than 1.9 for some reason.
Build looks great!
