Need Help!- tap cycles not posting properly from McV8

[firekoe]

i am trying to get master cam V8 to post a tap cycle to a fadal mill using the MPFADAL post but it post this:

N138 T3 M06 (T3 - DRILL/MISC - .375 DIA)
N140 S713.2 M5 M90
N142 E1 G00 X0. Y0.
N144 H3 Z.1 M08
N146 G84.2
N148 G84.1 G98 X0. Y0. Z-.5 R0.1 S713 Q-.0028 F713.
N150 G80
N152 M09
N154 G00 Z0 H0
N156 M01

i do not want the Q (peck) value and why does the feed the same as the ss. dose anyone know how to modify the post to fix this
the post look like this:

ptapfr # calculate tapping feed rate
if peck1 < 8, peck1 = ss / fr
tpi = peck1
# tapfr = ss/tpi
pitch = 1/tpi
tapfr = ss
*pitch, *tapfr, !frplunge

ptapmatic # calculate tapmatic feedrate
tpi = peck1
tapfr = (ss/tpi)*.95
*tapfr, !frplunge

G84.1 is a rigid tapping cycle.
If the feed rate is the same as the RPM it means your tap is defined as 1 TPI.
This is not good.
Check your tap definition in the tool manager.
If you have the standard Fadal controller you might want to be sure it is in format 2 mode.
It makes a difference how the machine moves and interprets code.
Also the macro programming language is slightly different, I think.

Which Fadal to you have?
I have posts for the 4020 and 3016.
I also have a "tall" post that takes advantage of the extra 4" of +Z the tool changer uses.
Yes, that area is useable/programmable.
If your machine is a different model/size I can modify one of the ones I have to suit your needs.

i have a few fadals 4020 4525 6030 everything in the post seems to work fine except for taping cycles so if you could help me rectify the problem that would awesome

Ok, can try.
Please post a copy of the post file you are having trouble with and I will take a look at it.

I'm not sure why your post is working this way.
I even looked at the original version for V8 and yours is different.

I have attached a Fadal post that I have personally used.
It gives you the rigid tapping option at posting time.

PLEASE BE CAREFUL UNTIL YOU KNOW IT WORKS LIKE YOU WANT!!!
If you need any changes made, I'll be happy to do them.

PS which controller is on your machine?
Here is a link for Fadal manuals.

thanks
