To elaborate on what Alex posted: dallur-thc is an old version of a gantry based plasma config which uses classicladder and has basic functionality.
plasma-thc is a newer version which only uses HAL and has things like corner height lock, realtime adjustable cutting height and more. plasma-thc-sim is a simulator config which should enable you to run the system without the hardware. The logic diagram for plasma-thc is maintained in an open office diagram which can be found in the plasma-thc config directory. http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/~checkout~/emc2/configs/plasma-thc/ Regards Jarl (dallur and rugludallur) On Sun, 2007-09-30 at 17:32 +0300, Alex Joni wrote: > Hi John, > > there are 3 sample configs supplied along with emc2, all refering to THC > (torch height control). > I'm not sure if they are both in 2.1.7 (current version), but they will be > definately part of 2.2.0 > > http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/configs/dallur-thc/ > http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/configs/plasma-thc/ > http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/configs/plasma-thc-sim/ > > There is also some information about this in the wiki at > http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Torch_Height_Control > > A more current diagram of the hal file (for the plasma-thc config) used is > here: > http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/~checkout~/emc2/configs/plasma-thc/README?rev=1.1;content-type=text%2Fplain > (hint: you need OpenOffice to view it) > > Hope this helps as a starting point. > If you need more info try on #emc on irc.freenode.net > > Best regards, > Alex Joni > > PS: thanks to Dallur/Rugludallur for some great documentation on the work > they did > > > > ----- Original Message ----- > > From: "John Thornton" <[EMAIL PROTECTED]> > > To: <[email protected]> > > Sent: Sunday, September 30, 2007 2:53 PM > > Subject: [Emc-users] Plasma Torch Height Control > > > > > >> Is there a way in EMC2 to read an analog signal of some sort > >> to control the Z axis of a Plasma Table?
