Are their plans for OctoPrint or RPI integration using GPIO pins or other input ? The switch is very .... in-elegant.

Hi,

from my point of view, the mechanical switch is definitely a smart idea to make the 3D Chameleon open for as many Printers as possible.

I am using a Prusa MK2s Clone and the switch works great. No problems at all.

Reading the comment form Bill might lead to change my mechanical switch to a solution within my Prusa clone firmware or in OctoPrint / OctoDash. I am thinking about that, at the moment.

Meanwhile I found this and tested it successfully:

MK2 Rambo pin available for LED control w/ Gcode?

In this video by Tom, he shows how to use a spare pin to control a led using Gcode commands w/ the stock firmware I want to turn on a LED when the n...

You can access this pin via Gcode with the original Prusa i3 MK2s firmware :

M42 P32 S255 to switch ON

M42 P32 S0 to switch OFF

This pin goes to IO extension header P2 pin 10 this header connects to the LCD panel Header 5X2 pin 10 (close to the reset pin).

Well, electronic switch connected to my miniRAMBO-Board now works. But would it also be possible to use one of the GPIO of my OctoPrint raspberry Pi?

Question to all of You: did anyone change the mechanical switch to an GPIO setting using OctoPrint on a raspbery Pi?
