GPIO usage on raspberry pi
Hello,
I use repetier server pro 0.90.1 on a raspberry pi.
I want to send gcode to a printer when a button is pushed.
The buttons are wired to GPIO22-27-17 of the rpi.
I use a python script to do triggers on GPIO (using Rpi.GPIO lib) and send gcode to repetier server via http (socket).
The communication with repetier server is fine.
But I have a strange problem :
Do repetier-server make any action with this GPIO?

But I have a strange problem :
- when the printer is not plug to the rpi (usb), my script work fine
- but when the printer is plugged, pushing buttons of GPIO27 or GPIO17 invoke actions of GPIO22 too!
