Circles on TRIAC

Hi there!

While using the heiden milling software i got in trouble.
Any instruction like below will cause a “Controller Communication” error.
This error shoot down the internal dos computer and the tool runs further on in a direction.

"
18 CC X-57,82 Y+355,578

19 C X+70,885 Y+145,772 DR+ R F300 M
"

Every time the circle centre lies clear out of the axis move range the error breaks any program!

Can anybody reproduce this effect on his own machine?

Is this a software-bug that can’t be evaded? If there is a way, what can I do?


Regards

Enny

It does sound like a bug - MrMagoo might know if there was a way around it.

Can you output the program via a post that breaks the arc up into smaller linear moves ?

Have you tried same thing in Fanuc ISO program format using I J or R ? It could be that the arc data to the machine is calculated differently from an ISO g-code format program

QuickCAM 2D design would allow you to CAD draw what you wanted and configure the post processor to do just that.

Early versions of the Heiden software for the Triac machine did have some bugs with arcs that were ironed out in later versions.

Many of the problems were related to the machine performing 'contour' moves (blending one move into the next without any pauses between NC blocks), and so turning contouring off may fix the problem.

This can be done by editing your HEIDEN.OPT file, changing the line that reads...

CONTOUR 1

to read...

CONTOUR 0

(The HEIDEN.OPT file is a text file and can be edited in windows NOTEPAD or DOS EDIT. If your HEIDEN.OPT does not contain a CONTOUR entry, simply add a new CONTOUR 0 line to the bottom of the file)

I will also be asking the Denford crew to post the most recent version of the HEIDEN software for Triac on their website. This new version MAY run on your machine, but don't be supprised if it doesn't, as I think the EPROM in your control card may be too old to support this later verion

:shock:

And here is the latest Heidenhain software for you to download and try out:

Hey there!

I'm deeply grateful for your support!
I will try out all suggestions and report the results.

@Magoo:
I know the contents of nearly all files in the control soft directory, unfortunately the sense of the values oftener nebulously :oops:
The Contour value is already 0. :(

Hi Enny...

I've just had a quick look at yr problem but don't have a solution :(

I do remmeber this being a bug that was fixed in later versions but your EPROM issues mean this doesn't help!

My only comment is perhaps you sepcify your arcs in a different format like Polar co-ordinates? this may help.
