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

« on: April 01, 2010, 11:10:01 AM »

Hi i own a shopbot cnc mill.  using mach 3.
i had some problems with my computer hard drive and lost mach3
i set up another computer installed and set up tuning  xy and z  also zero plate setting.
everything worked.
i then tried to run a file the z axis drove to the top and slammed into the stop.
i tried other files same problem.
also reinstalled everything same problem/
also tried another  computer same problem.
once this happen the zero plate does not work anymore.

Hi Tweakie
mach 3  R3.042.035
i had the setting correct  Go Z  0.5"
what i did was reinstalled your file.
this is what is going on.
the bit comes down touch the plate then retract 5.25 inches
from the top of the plate.
this is with your settings.
i am very new to mach3

thanks tweakie
i used your script and it worked  only you have the z axis retract as 5inches
i change this on the script but it still goes to 5 inches
eg  go z0 2" retract hight is set here.

General Mach Discussion / zero plate problem

« on: March 24, 2010, 06:24:59 PM »

I am having a problem using my zero plate
when the bit goes down and touch the plate it stops and does not go back up.
i then have to go and press the reset button,  send the bit up and down again.
then it works.
never on the first try
