Help with Position of Home and Piece Part
« on: March 26, 2006, 02:44:31 PM »
Please see attached doc for explanation of what I strive to do. I've read and reread the manual and watched the videos and I still can't seem to grasp it. :'( :'( :'( Also when I run G code from V Carve the machine runs it up in the air. The moves seem to be OK but, all it cuts is air and the Z axis movements are backwards. HELP!!!!!!!

Brian have you looked at my query attachment. I think this may have a lot to do with my ongoing problems. Take a look at it and see if you can tell me in plain English how to work it out. As I said I've watched the video on co'ord's and homing and find it very confusing for some reason.  I'm ready to throw this whole business int the toilet ;D ;D and get on to another very expensive hobby. LOL I'm insane, :-[ :-[

Hi Brian,
  Open that file with "wordpad" and it will show a graphic and a paragraph of what Stringkilla is trying to do.
     I wish I could help on this....

..or open this PDF file...

You could use a setting jig something like the picture.

Make the jig from 1/4" alum plate and bolt it to the machine table anywhere, then clock it square to the axis.

The 1/2" hole is a setting hole so you can clock it at the start and set X and Y zero at this point.

Then have G54 set at -12" and -6"

The 3 off 1/4" dia pins then locate the work in the correct place.

The drawing is in metric by the way.

  Thanks I think a fixture like that will work, as soon as I find out how to set my part Zero. Thanks for the idea.
