I did not build the ones in the file, it was Trevors.

I don't know what to make of this.

I post out three hole locations in one drill op (the last in the program), all top plane. All in minus Y space. It looks as it should as far as hole locations.

If I post out the whole program I get this....check out the last three hole locations....all the same as the above but X and Y are reversed, or the Y has changed signs?

I just cant figure that out. It back plots fine.

A plane was set for each face

Yes I tried the stock post the rotary moves are opposite of what they should be.

I got those corrected now discover this x/y issue.

I'm figuring that even if the 5 ax drill works then my x and y will still be off if I do 5 ax positional right?

I will try the 5 axis drill thing later when I have time, never done that before though I'm new to the 5 axis world anything special to know or it it pretty intuitive?

February 28, 2011

I got a rotary issue resolved, then discovered a new one I can't figure out

Machine is a Haas Vf2, with a TR110

have a proven post, mach and control def so there should not be any issues here but there are

I have a file with six drill points, one center, one on each side and one in the x-y- quadrant (the last hole listed in the code)

The trunion platter sits 3.1" above the center of rotation, the geometry I have about 6.3" above center of rotation in the software

The trunion table appears to be moving correctly (in real life) so far but the y axis looks reversed, tries to come down behind my trunion table (opposite side from the platter)

also the last hole in the code...the one programmed from tplane =top

if I post it alone I get this

which is correct as far as position in x-y-

if I post it with the other holes I get this

See how it reversed X?

and in the other holes it appears the Y direction is wrong?

So freaking lost here.

LOL

I know this is probably something simple but I have been banging away at this all day and just gotten nowhere.

Any ideas appreciated.

In most cases, there are 2 solutions for ever 5X vector on a trunion type machine..

You can usually for the on you want with misc settings mi4 , mi5 or mi10

mi4 - Start initial primary rotary axis bias

# +/-999 represents start as close to limit as possible

# 0 represents calculate without using bias

# Any other value represents an angle in degrees to attempt

# to position near.

# -999 = Low, 0 = Off/Default, 999 = Hi, Value = Angle bias

#

# mi5 - Start initial secondary rotary axis bias

# +/-999 represents start as close to limit as possible

# 0 represents calculate without using bias

# Any other value represents an angle in degrees to attempt

# to position near.

# -999 = Low, 0 = Off/Default, 999 = Hi, Value = Angle bias

mi10 - Secondary axis control (non-nutating)

# 0 = Continuous secondary (primary controlled)

# 1 = Always stay positive

# 2 = Always stay negative

I think I have the rotary direction thing figured out. It was MI10 that fixed it, set to "2", Trevors files had that correct for my machine too.

Now it appears to be a Y axis issue as described right above your last post.

Ever seen that?

February 27, 2011

Trevor has helped me quite a bit.

Still have a strange issue though.

When I post the file he sent (which is a proven good file for the Haas TR machines) the code posts out, bringing the z axis down behind the trunnion table, far as I can tell the Y axis sign is reversed, should be a -, and is a + number

I tried moving the trunnion model and geometry around to where my TR110 would sit and I get the same result.

(the TR110 is the really small Haas trunion, it has the platter 3.1" above the tilt rotation zero)

Anyone ever seen this before? Know what the fix is?

February 27, 2011

Hey thanks Trevor!

February 27, 2011

this tells you which is primary and which is secondary

#Assign axis address

str_pri_axis : "B"

str_sec_axis : "A"

str_dum_axis : "C"

this is where you make the changes

#Primary axis angle description (in machine base terms)

#With nutating (mtype 3-5) the nutating axis must be the XY plane

rotaxis1$ = vecy #Zero

rotdir1$ = -vecx #Direction <----add or remove a minus sign here

#Secondary axis angle description (in machine base terms)

#With nutating (mtype 3-5) the nutating axis and this plane normal

#are aligned to calculate the secondary angle

rotaxis2$ = vecz #Zero

rotdir2$ = vecy #Direction <----add or remove a minus sign here

this code is copied from a stock Haas VF-TR post

make a copy of you post before you start changing thin

Question

*edit* OK I got it to work by changing the secondary axis misc value.

Thanks for your help!

funny changes to the post did not change output...is it locked or something?

February 27, 2011

Ok Ill try those. Thanks for the help.

February 26, 2011

Does anyone know how to reverse the direction of the A and B axis on the Haas 5 axis trunion post?

I currently have it going away from the operator, needs to come toward me, rotation is wrong direction also.

Could not find it digging through the machine or control def. Is it a post setting?

February 16, 2011

Get mine from MSC, off the shelf stuff. Micro100 is the brand Ive used.

November 26, 2010

Dave was a peck cycle previously coded into that post because they are not by default? So someone would have had to have added the canned cycle, however I am still confused about your desired output.

Are you looking for long hand peck cycle output or G83 canned cycle?

Yeah I was looking for a canned cycle, G83.

But you may be right about the post I have never modified it and it may not have it in there I do not do much post modding except by specific advice I get here.

If it's not in the post no biggie I can live with long hand coded peck drilling

How do I get rid of the "V" when a g28 is called?

I get U, V, W as below.

I just need U and W, the V is throwing an alarm.

In the drop down I select peck drill then set .1 initial and .1 subsequent.

Post it....I get that output.

The custom cycle stuff on the third tab is unchecked

November 24, 2010

Dave,

you don't say how it's bad or what you should be getting, so I'll take a stab in the dark.

Have you gone into your control def and made sure the support for the peck canned drill cycle is unchecked?

Yeah I checked the control def it's checked.

The posted code for a peck drill cycle is in my first post there.

Instead of a canned cycle I got "customizable drill cycle" as the output.

I don't think my fanuc will understand that LOL

Weird.

Just got X5.

My generic 2 axis lathe post used to work fine.

Now with a peck drill cycle it outputs

1 2002 Daewoo 210LC (new addition)

1 2006 5 axis Haas vf2 (trunnion)

all in a little garage hobby shop.

sure its a little cramped but its not far to walk from the machines to the inspection dept or tool crib

The saw and raw stock department is about 3 feet away from the main shop floor.

Norton on my box did not pick up anything.

Brand new too.

iddn't dat funny.

I used MC all last eve after I ran that "fix" and everything seems to be working fine.

I have Norton set to not throw up warnings, just get rid of stuff without telling me so maybe that is what happened?

Or...Norton sucks and my (computer) box is now dripping with internet syphilis.

LOL

September 14, 2010

Colin....you fixed it.

Thank you very much!

Thank you everyone for the help

Does this help?

Got this from the event log. Can't decipher it though.
