G code help
« on: April 11, 2010, 05:17:17 PM »
i have fitted a laser pointer on my cnc  so that it makes it easy to centre my bit.
using MDI alt2  i enter this offset g0x-0.3709y7.0013  this brings my router bit to where the laser point was.
what i am trying to do is to put this in a file form.
instead of having to keep typing it in the MDI box.
just bring up the file and hit cycle start

You can add a button that calls a macro to do that

If you only want to go to the laser position the macro can be

Code ("g0x-0.3709y7.0013 ")

If what you want to do is zero the work coordinates in the laser position, you can do it without even moving

SetOEMDRO (800,0.3709)
SetOEMDRO (801,-7.0013)

Hi Paul,

The system I use is shown on this page http://www.cooperman.talktalk.net/files/17.htm

The scripts for the screen buttons are at the bottom of the page, obviously you need to modify the second one with your offset dimensions.

Hope this helps,
