HURCO VM1

[Dave-Newcastle]

Hi all.

 

Question, can a mastercam post be configured to allow 3d arc filtering on a hurco without the ISNC option? I have searched forum and can only find ISNC based topics relating to arc filtering. Any help from hurco users would be greatly appreciated. (or anyone else "in the know"!!!)

 

Thanks in advance.

 

Dave.

yes...............used one with ver 9 and earlier..............don't use anymore.....use only IS with X. (mpmaster)

A ver 9 post should be on the ver 9 mastercam CD.

I thought the Basic NC mode read plane change commands like G17, G18 and G19. I never tried it though. I always used the ISNC becuase otherwise you can loose your tool offsets if the machine is shut down.

[Dave-Newcastle]

Ive rad all about ISNC and MC but wondered if there is an X2 post that would output arcs in xz and yz without the loop the loop!!!

[Midwest]

Dave T. said a while back there was a basic nc post for X....... I'll try and find the link..............It might have said to contact your dealer.

We have Mpmaster variations for both the standard Hurco, and the ISNC. Your dealer can request these posts from us.

What loop is that?

[Dave-Newcastle]

Thanks for link, will have to ask dealer then!

Kunfuzed,

 

On hurcos (Basic NC) if arc filter is on they have been known to take the long route to the endpoint of an arc usually in xz, or yz so 5" rad in one of these planes ends up with the spindle moving down through the part acrossed back up and acrossed to the desired endpoint... this move almost always ends with a broken tool and axis overload.

[kunfuzed]

Ohhh.... So is this a Hurco problem, or is this a post problem? Is ISNC your only choice for XZ and YZ arcs?

[Fred @ Slate Industries]

If your getting Loop de Loop in 2d contours

(Usually small tight stuff)

I had to turn off "Wear" and use "Computer"

In MC.

The filter didn't matter.

[Carl Hessig]

The loop is caused by the way Hurco has there home position set to a different corner then everyone else. Not sure but I think this is what we had to change to get it to work.

 

Set the swg18 variable to 1 for Boss's left handed coordinate system

# on G18 plane - G17 and G19 have a right handed coodinate system. This will

# cause G2 to be outout as G3 and G3 to be output as G2 only when G18 encountered.

[Martin Oline]

Carl is right. Make sure you save an original copy of the post first. We use MPHUR.PST here which is included. Actually I think we installed it in ver9 and upgraded the post version to X. So that's no help if you're starting at X. The reseller (hollow be his name) was no help at all. Only the good ole boys at CNC came through for us.

The result: no maintenance - no upgrade - no sorry!

 

That whole YZ plane thing affects more than Hurcos. It's a european thing, kinda like how they view their drawing I guess: backwards.

 

The salesman said to use Industrial Standard but I've always used Basic. Had to tweek the post to get rid of the G75 at the start and only later ran into the loop de loop. Better than Pepe le Pieu!

 

I haven't had any problems losing TLOs but we're using a VMX Hurco machine model. The night guy uses conversational all the time. We just try to use different tool #s so as not to overwrite them.

 

If you need line numbers for changes I've made to the post drop me a line...

[babolino]

hllo al,

 

Can anybody post the line numbers for MPMASTER_X2 which have to be changed to get the correct gcode when G18 is active?

[babolino]

Anybody?

[Dave-Newcastle]

Thanks Carl, as a test on the "loop de loop" prog i swapped G2 for G3 and vise versa and it worked perfectly will have to get post tweeked!!!

 

 

Nothing is ever straight forward!!!!

[Fred @ Slate Industries]

Where do I put "swg18 variable"

In here?

“# ---------------------------------------------

 

# Select work plane G code

 

sg17 G17 # XY plane code

 

sg19 G19 # XZ plane code

 

sg18 G18 # YZ plane code

 

sgplane # Target string

 

fstrsel sg17 plane$ sgplane 3 -1

 

 

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

 

It never really bothered me As the only time I get the Loop is when I have a .0002 stepover

and the arc filter set to less then .001

 

But maybe its time to Iron this out....

(Martin your email bounces on me)?
