I don't want the M843 and M845 after each set of holes at a particular depth. A M843 at the beginning of the program and M845 at the end is sufficient. Can this be done? The reason I ask if it can be done is because we use feed moves instead of rapids so we don't get the dog leg move. Because of this feed move, the fixed cycles need to be cancelled...therefore rigid tapping need to be cancelled too? I was hoping to clean up the code a bit, but if it's required (or recommended), I'll leave it.

 

Here's ptap$...

 

code:

---

ptap$       # Canned Tap Cycle                                        81(3)

 

pdrl_setup # Do initial setup from drill/bore cycles

n$, "M843",e$ # TURNS ON RIGID TAPPING SYNC

if (n_tap_thds$ < 1), tap_feed = frplunge$

else, tap_feed = (1 / n_tap_thds$)

n$, *sgdrill, pdrlret, pxy_pos, *depth$, *refht$, *tap_feed, e$

rigid_tap = yes$

---

and here's the code that cancels it...

 

code:

---

pcanceldc$  # Cancel canned drill cycle                               80

if (rigid_tap = yes$), n$, "M845", e$ #TURNS OFF RIGID TAPPING SYNC

rigid_tap = no$

 

n$, "G80", e$

!gcode$ # Forces restatement of 'G' mode on next move

Put them in the ptlchg_com and pretract and see if that does what you are after Thad. I am assuming you are using MPMASTER.

Ron,

 

Unfortunatley, I'm using an old post (MPTOS888.PST) that has been updated since V7. I don't have time now to update to MPMASTER, but plan to when time allows.

 

This post doesn't even have a pretract section. And I'm not sure what I've move there is I did. I'm a post editing noob.

Thad,

 

There is a parameter in the control that will get rid of the dog-leg rapids...its one I ran across by accident. I will check my notes & see what I can find.

[Charlie Pierson]

Thad, Can you set a parameter in the control to straight-line the rapids instead of dog-legging?

 

[MIL-TFP-41]

Tosnuc 888 control

 

setting parameter 10 bit 1

1=linear rapids (straight line)

0=non-linear rapids (dog leg)

[Thad]

I'll give it a whirl. Thanks James!

Thad, Did it work ??

[Thad]

Yes it did, Charlie. I meant to get back to you guys this morning and I got too many things thrown on my plate. Now, I can continue with the post edits.

 

Thanks Ron, James and Charlie for your assistance. I just may be back with more questions.
