 # chuni-lite
-kinda cheap slidy air towers for an arcade chuni slider.
+Slidy air towers for an arcade chuni slider without backplate.  Bare minimum docs because I don't expect too many people to have access to chuni cab sliders without backplates.
+
+Current versions can be found at:
+- CAD: chuni-lite\chunair-cad\airs\print\f1
+- PCB: chuni-lite\chunair\chunair\chunair_v2\v2-1-2 & chuni-lite\chunair\chunair_core\v1

 Note: I swapped the side the pads are on for chunair_core.  Oops.  Wires will go across the board for now, no biggie.  WS2811/WS2812B optional.

+Can hand wire, or replace air_tower_top_1 3D print with chunair pcb.  chunair_core PCB also optional, but is there for ease of wiring(find a way to secure the pro micro if you don't use chunair_core)

 Basic steps:
-0. Wire up your slider's 12v and DB9.
+0. Wire up your slider's 12v and DB9.  Crimps recommended.  11" 4 wire recommended for 12v, 9" 3 wire for DB9.
 1. Print parts.  Then print a mirrored set.
-2. Assemble parts with hinge.
-3. Glue leds/pds if you are using air_tower_top_1.  Wire according to the diagram in "ac chuni/wiring.png".  If you have PCB, solder resistors and leds/pds
+2. Assemble slider_rail and air_tower with hinge, flat head screws, and nuts and insert into slider (double check orientation)
+3. Glue leds/pds if you are using air_tower_top_1.  Wire according to the diagram in "ac chuni/wiring.png".  If you have PCB, solder resistors and leds/pds.  With PCB, recommended wire length is around 30", 9 wires for RGB, 8 for no RGB.
+3a. If you want RGB, add a 3 piece WS2812B LED strip in the middle and solder it up like the picture.
 4. Shove unsoldered end of ribbon cable through the channel.
-5. Solder to Pro Micro or chunair_core pcb depending on what you have
-6. Thread M4 screws through rubber foot and slider to mount to slider.
-8. Mount DB9, 12v, and pro micro to mounting plate
-7. Unscrew the two m4 screws and add mounting plate with those screws
+5. Screw air_tower_top_2 to the pcb or air_tower_top_1(depending on which you have) using rounded m3 heads while threading through air_tower.  Don't forget to put the printed bumper piece on one of the screws.
+6. Solder to Pro Micro or chunair_core pcb depending on what you have.  Make sure you slide the slider_rail into the slider first before soldering.
+7. Repeat steps 2-6 for the other side.
+8. Use 4 m3x8 bolts and nuts to mount db9 and chunair_core to core.  Press fit 12v barrel connector and hot glue into place.
+9. Thread M4 screws through rubber foot and slider to mount to slider.
+10. Use existing M4 screws on the chunithm slider to mount core.
+11. Flash firmware and test to make sure everything works.  Then add adhesive rubber feet on each bumper in addition to the bottom of the airs.
