GaggiaBoard PCBv3.1/v4 Housing (Gaggiuino)

Status: Released! 

Compatibility Warning!

PCBv3.1 and PCBv4 (with onboard STM32 chip) are the only compatible PCBs. 
PCBv3 (which uses the WeAct BlackPill) is not compatible and should use the Protective Housing.

Description

This housing holds PCBv3.1 and PCBv4 from the Gaggiuino project. It's designed to protect the board while allowing access to all connectors without removing the housing. 

Why another housing? Some individuals removed their PCB from the older Protective Housing to change wiring/connections, powered up the system to test without reinstalling into the housing, and fried their board/components. This new housing drastically reduces that risk, plus it's smaller, stronger and more flexible, allows for much easier wire routing, and has better mounting options.

Parts

• Gap-filling or gel cyanoacrylate (super glue)

• Mounting Magnets (For magnetic machine housings, pick one option)
  Note: If your machine housing isn't magnetic you can use dual lock tape, hook and loop tape, or let the housing sit freely

  • Base Mount: 3 disc magnets, 5 mm dia. x 1 or 2 mm thick

    Note: you can use spare magnets from the HW Scales or ToFnLED models

  • Wall Mount: 2 disc or bar magnets, 12+ mm dia./width, 2 mm thick

Printing

• PETG (PLA/ABS/ASA won't work)

• 0.4 mm wall lines and nozzle

• 0.2 mm layers

• 2 or 3 wall lines

• orientation as modeled, no supports

Assembly

Gently pinch the end of the PCB retaining fingers to free them. Do not over-compress. You may also insert the PCB to break them free, but that'll scrape off a bit of the material.

Glue magnets in place. The base mount magnets are ideal for Gaggia Classic variants.

The wall mount magnets are an option for Gaggia Classic variants but are ideal for Silvia. Attach magnets as required, do not cover vents.

For Gaggia Classic variants, the housing should be placed in the back corner behind the funnel with the PSU and AC connectors at the base.

For Silvia, place against the wall as shown
