Hello fellow printers,
I am currently working on a silicone-based printer and am rather new to the whole subject of RepRap and printing, especially the programming side of it.
I was wondering if anybody here would be able to help me.
There is a problem I have, I want to actuate a dispensing-valve with air pressure and for that I am thinking to use a 3/2-valve that gets its signal from the RAMPS-board. Since I don't use any fans I thought about using the fan-signal (12V instead of 5) to trigger the valve. As I mentioned before, I have little experience in programming the board, is there anybody that could help me set that up?
I know about the different M-codes, but where exactly would I put one of these to turn the fan (and therefore the valve) "ON" every time I use the extruder? (So basically using the extruder-info to power the dispensing-valve)
I hope you guys understand what I mean, since this is a rather new topic for me I might have a little problem articulating myself in it.
I'd be happy for any help you can give me.
Thanks
Nordish
