Hi

I am meddling with a post for an 4 axis Maho 800C, and have a little issue figuring out how to output an feed-rate for the rotary table.

Code:

# Tool change
if prv_t$ <= mach, n$,"M5", e$
n$, psg00, [ if prv_t$ > mach | t$ > mach, "Z100" ] , "M5", e$
n$, t$, [ if t$ > mach, "M66", else, "M6" ], ss$*, e$
n$, *b$, fr$,e$
if coolant$ <> 0, n$, smcool,e$
prv_x$ = xh$
prv_y$ = yh$

fr$ is the tool feed rate, so that is not a good way to do it,

Generated code:
%PM9000
N9000 ( T )
N10 G17 T1 M6
N20 G52
N30 B0. F300.
N40 G81 Y35. Z59. F300. S3000 M3
N50 G79 X0. Y103. Z35.

The two last drill cycles is on another plane:-) I got it working, sort of... still need the feedrate:-)

any suggestions?

I hobe to get the substitute axis working at some point also:-)

The post is attached.

doh got another issue. when moving from top plane to my 90 degree plane, there are no B or F anywhere in the generated code. I have to take a look at that tomorrow!

Edit:

Nailed it!

ptlchg0$ # Null tool change
n$, "G74 z-1", e$
n$, *b$, *fr$, e$
if prv_coolant$ <> coolant$, n$, smcool,e$

It is all working now.

The feedrate is not needed when indexing, it just runs at max.

Got It working today, and did try to run a small program milling 3 sides on a part. but I have a problem when programming the backside of the part, it doesn't turn the B axis the 180 degrees. Could this be a bug in the post? or is me not doing it right in mastercam?

Are the any good tutorials on the web regarding indexing on mills?

I have an robot gripper part that I would like to try on the mill...

Hi there

Im trying to mill an contour on a test part with G1, I have the post putting out X Y Z B and Feedrate. But I want an Radius also in the post, as the control can calculate the feedrate with a distance from the center of the part.

Is there any way to copy the Z distance under a new name "R" ?

I have tried with some math, result = nwadrs(srotr, z$) but it also changes the Z to R in the code, so it goes G1 X Y R B R F a R too many:-)

Is there any educations online on the subject of making Mastercam Posts? I would like to take some education with this stuff!

edit:

By the way, I`m editing the 4 axis fanuc post to go with the machine, it is a lot easier than making the old one work for X5, still milling with the old post, but I want to mill with the B axis. I really dont care about how long it will tage to get the post running, but the wife and kid might at some point:-)

Cheers
