Add pushbutton to start specific program on SD card
Is it possible to wire a pushbutton to the RAMPS1.4 and then start a specific program from the SD card?
Maybe there is a code for defining a program name which can be activated by an input.
Thanks in advance!
Not directly possible.
You ca write a UI_ACTION in ui.cpp to start the sd print and configure a button to call that if you already use a lcd display. If not you can also use our custom events e.g. 100ms timer to check for button press and start print. It's just a small extra code you have to provide.
Thanks for the idea.
For now I solved it in the Gcode.
I used the commands below in my Gcode to:
- Wait on an input
- Set the SD file to byte 0
- Start the SD file
