safety zone

[ToddMerc]

We are using a MpMaster Generic Mill post modified by our reseller to program our Mazak horizontals. At set up we had the reseller set the post to retract the tool via a "G91 G28 Z0." at every index of the B axis. Since becoming more comfortable programming with MasterCam we would like to switch that retract to be able to use the safety zone as opposed to retracting all the way to zero. Where would I look in the post to find this? I don't have much experience at all with posts. Thanks for your help.

Since it is a custom post there is no way to know where they made changes. Best bet would be to contact whoever made the changes. More than likely they would be able to change it back without much effort.

If you look in the pretract/pretract0 post blocks you should see a line similar to this:

 

     pbld, n$, sgabsinc, sgcode, [if gcode$ = 1, sgfeed], *sg28, "Z0.", [if gcode$ = 1, feed], scoolant, e$

 

Comment out this line by putting a # in front of it:

 

     #pbld, n$, sgabsinc, sgcode, [if gcode$ = 1, sgfeed], *sg28, "Z0.", [if gcode$ = 1, feed], scoolant, e$

 

Since the safety zone will add extra moves in the nci, this should be the only change that's needed.

 

You may or may not have a G91 G28 Z0 at the start of the file as well, if you would like that removed, look in the psof post block for this line and comment it out using a #:

 

       #pbld, n$, sgabsinc, *sg28, "Z0.", e$
