Z RETRACT ISSUE

Hello everyone,
    I've been having trouble to have bad RETRACT at Z value.  G0 (rapid) X(value) Z(rapid) stays on the same line of which may cause diagonal retracts.  I have checked on the PRAPIDOUT and it is fine, is this issue come from MACHINE DEFINTION?  

 

 

Thank you for your help.

You probably have to edit the prapidout block  so that z in in a second line.

 

After a second look I have seen that before but it's probably from geometry that is wacky.  It's only moving.0001 

Hi Leon82,
    I have looked into the PRAPIDOUT as you suggested and where do I add a second line for the PZOUT?


Thanks



========================================= 

prapidout       #Output to NC of linear movement - rapid
      sav_gcode = gcode$
      if convert_rpd$ = one,
        [
        gcode$ = one
        feed = maxfeedpm
        ipr_type = zero
        ]
    #"DEBUG: ", ~mr3$, ~nextop$, e$
      if tool_op$ = 19, "M0(AGAINST PIN STOP HERE)", e$
      pcan1, pbld, n$, [if sgplane     <> sgplane, sgplane], `sgcode, [if sgplane     <> sgplane, sgabsinc], pccdia, [if gcode$ = 1, sgfeed]
        pxout, pyout, pzout, pcout, [if gcode$ = 1, `feed], strcantext, scoolant, e$
      gcode$ = sav_gcode

Here I would try. Move pzout.

 

But I think that will effect the rapid to the next cut. Not your retract from the current cut

I am not sure my way is right, here is what I've done.  If you think I am wrong, I am welcome to take the compliment.


Thank you for your time and looking forward for your next responds.

I meant move it to a new line in the prapidout block. Either below or above the line where xy and c are output 

I have seen what you are getting but I have never had problems from it.

I don't have any issue either until I have a 5AXIS machine of which is very PICKY when someone from fanuc WROTE a macro of which FORCES

 

X... Y.... rapid in one line
Z... rapid in one line with M9 on the same line.

 

EXAMPLE...

G0 X.2588 Y.369

Z1. M9

then... LASER tool measurement macro starts here, like to check tool break or blowing off the TOOLS PRESETER throughout the AIR BLAST. M7
