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.

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, :-[ :-[

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, I I've been so busy with a room repaint I haven't had time to try. I am not at all versed in cam at all I believe some of me trouble lies there but I should be able to get to work.

Hi guys. I have tried to use the G56 fixture area while setting up to run my first part. Then I get back to the main screen and try to posititon it on the screen that shop my table, that's when it hits the fan. As soon as I try to move in that area with my mouse it go haywire, losses it's orientation and goes rotational on me. Any input as to what I'm doing wrong here. Oh the machine drilled a hole deep into the table and tried to move from deep in the substrate..

Well if I add them just as a precaution, what values would I need? Please add your recommendations. Thank you.

set debounce already at 2k and the index at 2k but it's still happening. Is it possible I may need to ground my machine to a bolt or screw ?

Yes, strange indeed. Well if I extend my arm toward the machine, and come within four to five inches of the frame. a limit switch triggers on. I haven't run any parts yet because of this occurrence. I have a two conductor wire, 22 gauge, taped to the mdf table with alum. tape, connecting the two limits to a shielded cable to my breakout board. It seems as if the electrical field of my body is grounding out the system, could this be so? Any ideas as to why this happens.
