That would be nice to hook it to EXT pins on sanguinololu, so that you can slow down or pause the print to allow you to append some filament to the end of it in time.
(I'm thinking of machining a custom brass crimper that will allow to fuse some filament to the end of the wire)

Maybe you could combine that switch assembly with this, and get it to run a @pause command into repetier.

Whats the Makey-Makey bringing to the party ? You can just hook the microswitch straight to any old digital pin exposed on the Sang or RAMPS boards, and add a firmware hook straight to Marlin that when that pin goes low (since its a NC switch to ground) have it issue the @pause command. Pretty trivial to add really, with no need for extra hardware. Or have I missed something ?
Should be easy to mod the existing Camera Trigger Code to work.. its the same concept, just in reverse order
Re: hey!! you are out of filament" alarm 1.75mm
ok, i know nothing about modding the firmware. I would love a detection system for low/no filament. Would make it easy to use up the last of a spool

If I have a chance over the next day or so, I'll knock together a test setup. Will let you know. You able to source the microswitch with the roller? if so, will just need to find out a pin to hang it off on the Sang (I'm currently on a RAMPS board, so will find a common one if I can....)
Re: hey!! you are out of filament" alarm 1.75mm
Yeah you definitely don't need the makey makey. Marlin can pause repetier-host remotely.

Ok, the current M600 command in lawys' marlin sorta does what we want, but is limited to need an LCD panel and lacks adequate restart commands and the ability to extrude during the change to flush colors
An improved M600/M601 command set is out there as a fork of the original marlin, but it by default still requires an LCD.
Over the next day or so I'll unpack the commands from a requirement to have the LCD display and see what we can sort out

Nearly there; http://www.soliforum.com/topic/2470/bet … t-chg-etc/ has the firmware in its almost ready state - the neccesary pause and firmware triggered repetier-host pauses are in place; just finishing work on ironing out the pin detection and loop before I post that up as well. Another couple of days on that one.
