Modifying mp master

[Beardog]

Hello,

 

How would I go about modifying the mpmaster to turn this off?

Don't output an on code for a coolant that is already on.

So it will turn on at a tool change even though it is the same tool.

 

Thank you,

[Tony35]

beardog try this i think this is what you want

 

search for this in the post.... ptlchg0$ #Call from NCI null tool change (tool number repeats)

 

if plane$ < 0 | opcode$ = 3 | opcode$ = 16, plane$ = 0

if op_id$ <> last_op_id, pbld, n$, sgplane, e$

pspindchng

if coolant$ <> 0 & coolant$ <> sav_coolant & sav_coolant, pbld, n$, sm09, e$

pbld, n$, scoolant, e$<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< PUT A # IN FRONT OF THIS LINE

sav_coolant = coolant$

if coolant$ = 1, sm09 = sm09_0

if coolant$ = 2, sm09 = sm09_1

if coolant$ = 3, sm09 = sm09_2

if op_id$ <> last_op_id, pstock

if sav_mi9 = 1, workofs$ = sav_workofs

No that did not work thanks for trying

[Brad Lisle]

just to clarify? Do you want it to output the M9? and the M8 at every Null tool change? or just the M8 without the M9?

[Tony35]

+1 what Brad said

[Beardog]

Both thanks

You said it is a mpmaster post, do you have "cool_zmove : yes$"? And are you using force tool change for the 2nd op? My mpmaster gives me this...

Yes it is set to that.

 

this all started with X5 and haveing to change from x style coolant.

with x style if I force coolant it comes out right.

but when I chang back to support old coolant it will not work.

[Beardog]

I missunder stood the question I want m8 and m9 at every tool change sorry about that.

[K2csq7]

Does it work correctly with a normal (actual not null) toolchange?

[Beardog]

yes it does.

[K2csq7]

Give this a shot, (backup post first)

 

near the bottom of the ptlchg_com postblock add * in front of scoolant in the second line you see below

 	phsm1_on    	#must remain before G43
 	pbld, n$, "G43", *tlngno$, pfzout, *scoolant, next_tool$, e$
 	pcan2   		#Added so M and G codes in canned text will output before phsm2_on
 	phsm2_on    	#must remain after G43
 	sav_coolant = coolant$
 	if coolant$ = 1, sm09 = sm09_0
 	if coolant$ = 2, sm09 = sm09_1
 	if coolant$ = 3, sm09 = sm09_2
 	absinc$ = sav_absinc
 	pcom_movea
 	toolchng = zero
 	c_msng$ #Single tool subprogram call
 	plast

ptlchg0$ 		#Call from NCI null tool change (tool number repeats)

 

then in the pretract postblock add another * in front of the scoolant in the second line you see below.

 	pbld, n$, sccomp, *sm05, psub_end_mny, e$ 
 	pbld, n$, sgabsinc, sgcode, [if gcode$ = 1, sgfeed], *sg28, "Z0.", [if gcode$ = 1, feed], *scoolant, e$ 	################test
 	#if lock_codes = one & rot_on_x, pbld, n$, *sunlock, sunlockcomm, e$
 	#pbld, n$, *sg28, "X0.", "Y0.", protretinc, e$
 	#if lock_codes = one & rot_on_x & cuttype = 0, pbld, n$, *slock, slockcomm, e$
 	if abs(fmtrnd(cabs)) > 360 & nextop$ <> 1003 & not(index),
   	[
   	if lock_codes = one, pbld, n$, *sunlock, sunlockcomm, e$
   	rotretflg = 1
   	pbld, n$, `sg28, protretinc, scoolant, e{:content:}nbsp;   
   	rotretflg = 0
   	if lock_codes = one & cuttype = 0, pbld, n$, *slock, slockcomm, e$
   	]
 	absinc$ = sav_absinc
 	coolant$ = sav_coolant

pretract0    	#End of tool path, null toolchange

[Beardog]

that worked for the m8.

now I just need to figure out how to add the m9 to the first tool.

 

thanks keith

[K2csq7]

Not sure if the toolchange after the first toolpath is considered null if you are forcing the toolchange, but in the ptlchg0 postblock you could add another * before scoolant... second line below.

 	pbld, n$, sccomp, psub_end_mny, e$
 	pbld, n$, sgabsinc, sgcode, [if gcode$ = 1, sgfeed], *sg28, "Z0.", [if gcode$ = 1, feed], *scoolant, e$
 	#if lock_codes = one & rot_on_x, pbld, n$, *sunlock, sunlockcomm, e$
 	#pbld, n$, *sg28, "X0.", "Y0.", protretinc, e$
 	#if lock_codes = one & rot_on_x & cuttype = 0, pbld, n$, *slock, slockcomm, e$
 	if abs(fmtrnd(cabs)) > 360 & nextop$ <> 1003 & not(index),
   	[
   	if lock_codes = one, pbld, n$, *sunlock, sunlockcomm, e$
   	rotretflg = 1
   	pbld, n$, `sg28, protretinc, e$
   	rotretflg = 0
   	if lock_codes = one & cuttype = 0, pbld, n$, *slock, slockcomm, e$
   	]
 	absinc$ = sav_absinc
 	coolant$ = sav_coolant

protretinc  	#Reset the C axis revolution counter

 

 

If you want to find it for sure run the post debugger and find out where that G00 Z1. (the line you want the M09 on) is coming from.
