What Post?

 

The Generic Fanuc "style" posts from Mastercam use Canned Text as the function to output Parts Catcher. They call it a "Schute". (I don't know why).

 

Canned Text option #7 and #8. #7 should retract the catcher, and #8 will engage it. Edit your output strings here:

# Chute M code selection
sm73    : "M73"      #Chute retracted
sm74    : "M74"      #Chute engaged
schute  : ""         #Target string

fstrsel sm73 chute schute 2 -1

Here is the code from Canned Text that actually turns the options on/off:

        if cantext$ = 7 | cantext$ = 8,
          [
          if cantext$ = 7, chute = zero
          else, chute = one
          rslt_upd = updstr (schute)
          strcantext = strcantext + schute
          ]

It looks like the post defaults are already setup to output the M codes you need. You just need to use "Canned Text" instead of Misc Values...

I have been tinkering with a lathe post and want to use the canned text to turn on the spindle brake (clamp) to mill in the Y-axis. In my post it is designated as "sm73_1" and "sm74_1" even though this is normally reserved for the chute  

# Chute M code selection (Main Spindle)

sm73_1    : "M69"      #Unclamp

sm74_1    : "M68"      #Clamp Engaged

sclamp1   : ""         #Target string

 

fstrsel sm73_1 clamp1 sclamp1 2 -1

 

There is no identification for the actual chute (parts catcher) with M-code calls like M73-74 or string select designation. 

Could I create a new chute selection with the correct code selection like the one posted previously by Colin

# Chute M code selection
sm73    : "M73"      #Chute retracted
sm74    : "M74"      #Chute engaged
schute  : ""         #Target string

fstrsel sm73 chute schute 2 -1

and change the sclamp to a different designation? I'm also not sure how to add the "new" sclamp correctly within the cantext$ to use custom canned text option 1107 and 1108 for example.

Any help is appreciated.
