There are 12 of these bad boys divided into two halves, set to channel 1-6 on each side that feed back into 2 touch unit control boards. Each one weighs x grams which totals to about 40 LBS. Somehow I never really understood how MASSIVE these units are until I held an individual segment in my hand.

Wacca LEDs are notorious for being burnt out, you've likely received your machine in a state where some panels are not getting color data, are dim, or are straight up not lit up. This is partly due to the design of WS2812.

Upload the gerber zip, select the side that has all the LEDs as the top stencil (wacca_ws2813_f_paste.gtp), and make frameless stainless steel 5mil. Should cost about $50.

Get some solder paste and apply it to the PCB using the stencil, apply the SMD components, put it in a modified oven or on top of a modified clothes iron (or maybe you can use hot air at low flow) Get some solder paste and apply it to the PCB using the stencil, apply the SMD components, put it in a modified oven or on top of a modified clothes iron (or maybe you can use hot air at low flow)
Replacing the board on the touch panel
TODO: post a more detailed guide with photos
But this process is pretty easy, for most of them you dont even have to remove the panel but let's assume you're replacing all 60.
1) Remove the screws holding the panel in the frame, remove panel
2) Remove the ribbon from the pentel touch pcb and unscrew and remove the pcb
3) Unscrew each PCB and pull them out
4) Place in the new PCB and screw everything back together
Tip: You can "grip" the ribbon to feed it back through the hole to get it back into the pcb by using painter's tape.
Be gentle here though, broken ribbons are no fun.
