With a 24V bed the SSR is not used, and the bed heater is directly connected
|
|
to the bed heater output on the controller. I suggest using a SKR Mini E3
|
|
V2.0, which can control 2 heaters and 2 fans (unlike V1.2, which has only 3
|
|
controllable outputs).

Instructions
|
|
------------
|
|
|
|
For rear mounting, print both `skirt_rear` files and `inlet_bracket.stl`.
|
|
Mirror the skirt pieces if you want the inlet on the right side. Each piece
|
|
mounts to the rear vertical extrusions with two M3x6 screws. The rear deck
|
|
panel must be removed. Temporarily remove the rear panel and rear feet to
|
|
access the extrusion slots.
|
|
|
|
For side mounting, print `skirt_side_with_inlet.stl` and `inlet_bracket.stl`.
|
|
It replaces an existing skirt piece; mirror it in your slicer if desired.
|
|
|
|
Inlet and switch mounting steps are shown below. It is suggested to solder
|
|
wires to the inlet before assembly. Pay particular attention to the order of
|
|
the inlet pins, and confirm with a multimeter.
