Assembly

Step 1

Disassemble the Boss RE-20 Space Echo and remove carefully the glued metal sticker in the center of the device. Disconnect the two ribbon cables of the PCBs since the front PCB needs to be trimmed that it fits into the Eurorack.

Step 2

Cut small strips with the hand saw from the RE-20 front PCB (the PCB which contains the potentiometers and LEDs) that it fits later into the Eurorack.

Step 3

Unsolder all jacks and solder cables to connect the Eurorack jacks to the PCB. Solder the jacks to the cables and screw the spacers with existing screws from the Boss RE-20 onto the back of the front PCB.

Step 4

Screw the Boss RE-20 aluminium panel with the 3D printed front panel with two of the Boss RE-20 aluminium panel screws together. Widen the holes for the screw on the top of the aluminium panels with a drilling machine (or similar) until the two holes of the aluminium panel align with the threads of the Eurorack.

Step 5

Align the 3D printed buttons on the 2 switches of the RE-20 PCB and screw PCB with 4 of the existing screws (from the Boss RE-20) on the back of the 3D printed front panel

Step 6

Align the cables between the two PCBs, connect the two ribbon cables and screw the PCB onto the spacers between.
