Jeshua, wrt the words, assuming you look at the master branch
The existing 'S' (spindle speed) and 'F' (feed) can be redefined with an NGC procedure or Python code. New 'M' codes can be either introduced by the same method, or the 'M100 to M199 User Defined Commands' feature see documentation here, http://www.linuxcnc.org/docs/devel/html/remap/structure.html and configs/sim/remap for examples I'm not sure that the F on each line per se would actually be a problem with linuxcnc, as I dont understand what 'totally messing up Mach3's movement' means in this context re serial I/O: it would be straighforward to build a HAL component which takes a float input pin and outputs some serial command if its value changes. --- let me know when you start working on it, I'willing to help a bit. I think it would be great to have a working config for linuxcnc demonstrating how it can drive a 3D printer. - Michael Am 29.05.2012 um 07:00 schrieb Jeshua Lacock: > > Greetings all, > > I have been dreaming of making a removable plastic extruder nozzle for my > machine.
