Hi All I've looked at that .h file with the debug defs in it, but I can't seem to find a bit that would, at each line of code, output the var number and its value for all vars used in the current line of gcode. Having that would make troubleshooting a lot easier. Something that looked like: line (# agrees with vim) #14=0.3119, #12=0.525, #13=0.075 Is there such a capability? -- Cheers, Gene People having trouble with vz bouncing email to me should add the word 'online' between the 'verizon', and the dot which bypasses vz's stupid bounce rules. I do use spamassassin too. :-) Yahoo.com and AOL/TW attorneys please note, additions to the above message by Gene Heskett are: Copyright 2006 by Maurice Eugene Heskett, all rights reserved.
