Custom tap cycle G84 for Mori Seiki mill with Fanuc control

[PGcam]

Hello!

Our ancient Mori Seiki 3X mill can only run the G84 properly when it is formatted in a weird way. I'm attempting to modify the generic Fanuc 3X mill post processor, so it outputs the tapping cycle in that weird format in my gcode. I got it mostly, but cannot figure out how to get the safety line "G0 G17 G40 G80 G90" to show up above my G54 line in my tapping gcode (only for tapping, not other toolpaths).

Please help!

Open your post xxxxx.pst, search "  pbld, n$, "G43", tlngno$,  pfzout, pscool, e$ ",   it  after  about "G0 G17 G40 G80 G90",  "sgcode sgplane sg40 sg80 sgabsinc", or use  other codes  replace this line; 

cut this line codes to be above "pcan1, pbld, n$, *sgcode, *sgabsinc, pwcs, pfxout, pfyout, speed,  pspindle, e$ ".

or you can upload your post  to do it.

hope to help you.

¡Hola!

Nuestro antiguo molino Mori Seiki 3X solo puede ejecutar el G84 correctamente cuando está formateado de una manera extraña. Estoy intentando modificar el postprocesador de molino Fanuc 3X genérico, para que genere el ciclo de roscado en ese formato extraño en mi gcode. Lo entendí en su mayor parte, pero no puedo entender cómo hacer que la línea de seguridad "G0 G17 G40 G80 G90" aparezca encima de mi línea G54 en mi gcode de toque (solo para tocar, no para otras rutas de herramientas).

¡Por favor ayuda!

Bro, send your pst file

OK this is my current production post processor where I'm trying to modify the G84 tap cycle

Zor, 

Adding "G0 G17 G40 G80 G90"

above 

pcan1, pbld, n$, *sgcode, *sgabsinc, *sgplane, pwcs, pfxout, pfyout,
        [if nextdc$ <> 7, *speed, *spindle], pgear, strcantext, e$

... inserts "G0 G17 G40 G80 G90" to every toolpath in my NC output, but I only need it for my tap G84 cycle

[Werktuigbouwer]

Try adding:

if nextdc$=3, pbld, n$, *sgcode, *sgplane, scc0, sg80, *sgabsinc, e$

into psof, ptlchg0$ and ptlchg$ at the place where you want them. PWCS will write for you the G54.

Also remove you're hard coded line in ptap

 

Good luck and try carefully

[Zorander]

try this, it's OK.

G84 and rigid G84.
