3 axis mill

I have 1 operation with 1 slot as the chain.

I then transform rotate 33 times.

I would like the post to perform 1 slot with a block # of N1, retract with G91 G28 Z0, M01 after the first slot

then have the next slot start with an N2 and full restart of tool info

ect, ect 33 times

 

1mm endmills, so I want to restart on any given slot due to breakage

 

I havent had any luck getting this output to work with transform paths even with force toolchange or safe retract

 

short of using a macro

anyone with an idea?

[Leigh @ Kodiak]

I'm not sure about the line numbers, but you could use a manual entry toolpath for your G91 G28 Z0, M0,. and just include the manual entry path in your transform operation.

[mayday]

I did try that,

worked except for getting an rpm call and a G43 "H" line which would be needed if the operator restarted on any of the 33 slots

 

I was looking for a way to force all the tool start code between slots.

to bad transform didnt honor the force retract between toolpath geometry

[K2csq7]

First I don't think "Safe retract" will help but set mi10 to 1("M00 before operation") that should give you the safety codes.

Second go into the Transform op's parameters and on the 2nd tab go into the custom parameters and set custom integer #4 (just picked the 4th at random) to 17, (just a random unique #)

 

Then format a new variable for your counter...

fmt "N" 			4   twes    	#

Create a new postblock to handle the counting and output...

pwes
 	pbld,  twes, "---------------------------------------------------Here it is Wes", e$
 	twes = twes + 1

Initialize the variable at 1...

psof$        	#Start of file for non-zero tool number
 	twes = 1

Call up the postblock in the ptlchg_com postblock

if trans_mi4$ = 17, pwes

I put it right before these 2 lines...

  	spaces$=0
 	if output_z = yes$,

Then I put this in the ptlchg0 postblock

   	if trans_mi4$ = 17, pwes

Right before these lines....

    	if retractflg,
     	[
     	if safe_index,
       	[
       	if lock_codes = one & not(index) & rot_on_x, pbld, n$, *sunlock, sunlockcomm, e$

I woulda posted yesterday but forgot to check this fancy new "Post Processor Development Forum" ;)

hhhmmm

gonna have to try that

Thanks Keith, I seen the custom parms in the transform opp but didnt have a clue what to do with em

Let us know if it works for you.....

[mayday]

ok,

I am running depthcuts with keep tool down.

turned on mi10, addded the code you showed

now I get full retract after every depth of cut instead of between slot positions

[K2csq7]

now I get full retract after every depth of cut instead of between slot positions

Instead of or in addition to?

I didn't know you were using depth cuts.....that's a bit trickier....I'll see if I can come up with something tonight.

[mayday]

It did that before. Dosnt make sense the post does that to begin with. I do get N block sequencing now

 

good job Keith

I used to do a bit of post edits back in pre X, but now I get a little lost in there

[K2csq7]

I don't follow??

Are you getting what you wanted??

[mayday]

sorry,

no I get sequence N blocks now, but with depth cuts on and keep tool down I get a full retract between depth cuts.

I need it to stay down until all depth cuts are done, then full retract with stop

new sequence # and full restart commands on next slot

[K2csq7]

Not the prettiest, but here goes...

First, In the original op's parameters, change mi10 back to zero. I have rapid retract checked, clearance & retract off, feed plane set to 1.0 (abs), and top of stock is zero. Leave the transform op's params the same...

Add these 2 format statements.

fmt 	2   wesdepth	#
fmt 	2   sav_wes 	#

In the pparameter$ postblock add this line.

  		if prmcode$ = 10029, wesdepth = rpar(sparameter$,1)

Here is what my pwes postblock looks like now...

pwes
 	if wesdepth = sav_wes,
   	[
   	pbld, n$, "M05", e$ n$ "G91 G28 Z0.", e$ n$, "M00", e$

   	pbld,  twes, "---------------------------------------------------Here it is Wes", e$
   	twes = twes + 1
   	pbld, n$, *sgcode, *sgplane, *sgabsinc, *pwcs, pfcout, pfxout, pfyout,
     	pfspindleout, e$
   	pbld, n$, "G43", *tlngno$, pfzout, *scoolant, e$
   	]

At the end of the prapidout postblock add these lines...

 	if trans_mi4$ = 17 & not(zinc), 
   	[
   	pwes
   	]

At the end of the plinout postblock add this...

 	sav_wes = zabs

 

Give that a shot & let me know if you get what you want. I see good results here.

[mayday]

something got lost on my end

If you want I can send my pst to you.

It outputs as it did before any edits

[RandleXX]

What about forcing a toolchange? (under "Tool" in the operation parameters) Then the tool will retract between every operation and have the required S and H codes.

[K2csq7]

Just noticed all of the indentation on my bracketed code is not displayed correctly, did you indent the bracketed code correctly? Go ahead & send it over if your really stuck [email protected], just rename the file extension from .pst to .txt
