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?
