I'm not quite done adding that code, figured I had better take the missus someplace for a nose bag.
Thanks Jim. Next, I am trying to figure out a way to make the jig move in and out automatically, and I think am out of pins on that db25. First I'm going to demolish an old cd reader because the tray motor is exactly what I need for that since the jig itself is only about 2oz. Then find some 12 volts to run it. Lots of fun. I want the gcode to self calibrate everytime I hit the r key after clamping up a fresh workpiece. The fewer operations it relies on me to do, the better off I am. And moving the jig in and out is one of those easily forgotten until its chewed up things. > I am using this same setup to allow me to change speeds on my variable > speed head. > > Jim > > On 8/10/2015 9:47 AM, Gene Heskett wrote: > > Greetings; > > > > How often does LinuxCNC save the position.txt file? > > > > I note that if there are touchoffs in use, re-homeing the machine to > > its homing switches does not clear the touch offs and this could be > > the source of some useful data. > > > > However, I would like to automate its finding a brass jig dohicky on > > the top of a hinged board that gets flipped up to serve as a > > positioning guage fixture for the workpiece.
