I would like to cause a set of GPIO pins high before a job, and once it is complete, set them low. Ideally it would be great for whatever script is setting the pins high could scan the gcode of the job. Based on whether a specific comment was in the gcode, that would effect which pins were set high. I would also like to read a GPIO value and if it is high, open a dialog in the web interface to warn the user. Is this possible with Repetier-Server? How and where do you create the pre and post job handlers? Thank you.
