Fadal Post question

[Surface]

I've been using the same post since V5, but I think it's time to update. I downloaded both Fadal posts from the V9.1 CD (Fmt1 and fmt 2), but I fear that both of these have a small bug.

When Mi1=2,the post should output fixture offsets as "E". The fixture offsets can be modified from the WCS. Yet I need to input "0" in the work-offset box for the post to output "E1". If I enter "1" the post spits-out "2".

Is it the post that's wrong, or is it my way of thinking?

Also, I hate to spend the time customizing a new post, which may not work with V10. Is there any word whether V9 posts will be able to utilize the features of X?

Way out in left field is the posts of the Disk. Have your dealer contact Dave at In-House-Solutions to get the MPMASTER_FADAL post you will be very happy with this post. I have added Can cycles and well as manunal indexing to my post and it kicks but. Thanks Dave.

The default posts ao the CD are set up to use work offset 0 as the first offset then increment from there. This is due to the auto-numbering that Mastercam will do for multiple tool planes. Most people do not use the feature however so it's a little counter intuitive when you're dealing with a machine that uses offsets 1, 2, 3, etc. instead of 54, 55, 56, etc.

We recently updated to the post on the SP2 CD and that was one of my questions also. My dealer said there would be no problem using this post when X comes out.

Well Glenn it is an easy thing to fix in the post. Here is what I did to the pwcs:

code:

---

pwcs            #E coordinate setting at toolchange

if mi1 > one,

[

sav_frc_wcs = force_wcs

if sub_level, force_wcs = zero

if workofs <> prv_workofs | (force_wcs & toolchng),

[

if sub_level, result = mprint(swrkserror)

g_wcs = workofs + 0

*g_wcs

]

force_wcs = sav_frc_wcs

!workofs

]

---

Then all you have to change this format statement:

code:

---

fmt  E  4   g_wcs       #WCS G address  

---

and this will output the corretc Fixture offsets for the Fadal 1=E1, 2=E2 and so forth.

This is what we did. It is the way to go!

I also like the MPMASTER_FADAL post - I modified it according to my own desires of course....

I just received the MPMASTER_FADAL post from my reseller. I changed the line below to read as you see and it still outputs A- moves..what's the deal?

 

one_rev : 1 #Limit rotary indexing between 0 and 360? (0 = No, 1 = Yes)

[crazy^millman]

What about this line:

code:

---

 rot_ccw_pos : 1     #Axis signed dir, 0 = CW positive, 1 = CCW positive 

---

and here is how that section of my post is set:

code:

---

# --------------------------------------------------------------------------

# Rotary Axis Settings

# --------------------------------------------------------------------------

# Typical Vertical

srotary "A" #Rotary axis prefix

vmc : 1 #0 = Horizontal Machine, 1 = Vertical Mill

rot_on_x : 1 #Default Rotary Axis Orientation, See ques. 164.

#0 = Off, 1 = About X, 2 = About Y, 3 = About Z

# Typical Horizontal

#srotary "B" #Rotary axis prefix

#vmc : 0 #0 = Horizontal Machine, 1 = Vertical Mill

#rot_on_x : 2 #Default Rotary Axis Orientation, See ques. 164.

# #0 = Off, 1 = About X, 2 = About Y, 3 = About Z

rot_ccw_pos : 1 #Axis signed dir, 0 = CW positive, 1 = CCW positive

ret_on_indx : 1 #Machine home retract on rotary index moves, (0 = no, 1 = yes)

index : 0 #Use index positioning, 0 = Full Rotary, 1 = Index only

ctable : .001 #Degrees for each index step with indexing spindle

one_rev : 1 #Limit rotary indexing between 0 and 360? (0 = No, 1 = Yes)

lock_codes : 1 #Use rotary axis unlock/lock M-Codes? (0 = No, 1 = Yes)

use_frinv : 0 #Use Inverse Time Feedrates in 4 Axis, (0 = no, 1 = yes)

rot_feed : 1 #Use calculated rotary feed values, (0 = no, 1 = yes)

maxfrdeg : 2000 #Limit for feed in deg/min

maxfrinv : 999.99#Limit for feed inverse time

frc_cinit : 1 #Force C axis reset at toolchange

ctol : 225 #Tolerance in deg. before rev flag changes

ixtol : .01 #Tolerance in deg. for index error

frdegstp : 10 #Step limit for rotary feed in deg/min

As far as I know the Fadal must have a signed "A" as this specifies the direction of movement.

I have the same settings as you Millman. I went ahead and ran the posted code and it works great!! Thanks for sharing all your info everyone. This is the 1st place I come when I have a question and have always found the answers I need.

 

Thanks again!

Another satsifed customer. Yeah think you will find that to make life alot easier on you.
