Edgecam Mach3 post problem

[mrjoesnow]

Im having real trouble making a new post for edgecam,

I get the error 'RIJK words all missing for arcline 031'


this is a snippet of the code with trace:

***** Code Constructor : 2D Circular Interpolation *****
N30 G2 X-64.752 Y-1.658 R0.296
***** Code Constructor : 2D Circular Interpolation *****
N31 X-64.655 Y-2.057
***** Code Constructor : 2D Circular Interpolation *****
N32 X-65.158 Y-2.068 R0.297
***** Code Constructor : Linear Interpolation *****
N33 G1 X-65.259 Y-1.961 M41

I am assuming that it just needs the r value again on the next line but how can this be done? I.ve found the relevant tokens in the code constructor but cant work out how to add another r value...

please can someone help?

It could be that your mashine does not accept the parameter to be xxx (forgott the word) open the post at general motion go to circular motion and right click on the R word and select always output. then it will be printed even when it is the same value as on the last line.

modal! the word i forgot is modal ...
modal means that it is remembered and not "outputed" until it changes
there is also a special settings tab where you select what parameters are modal

hi tummen, thanks for your quick reply...

there is a modal tab in NC style..

This has sorted it, thanks

its not drawing the arcs properly but I'm hoping thats the arc centre type which I will fiddle with now.......

[tummen]

In heidenhain you have to specify in a certain way if the arc is more ore less then 180 degrees for the mashine to know what type of arc to make. this problem can be eliminated by telling edgecam to never output more then 180deg circles. This is taken out of my memmory, I cant check because I don´t have the key at home.
Another solution is to ask the post processor to swap from using R to outputing I and J circle center coordinates.

Hi mrjoesnow,
If you don't want to turn off modality for all G Codes
In the Code Wizard Constructors for 2D and Helical interpolation
you can select the tokens and set Force Output Now

[DELETE][BLKNUM][PLANEGCODE][<C>CLWGCODE][<C>XARCEND][<C>YARCEND][<C>ZARCEND][<C>IVALUE][<C>JVALUE][<C>KVALUE][<C>ARCRADIUS][SPEED][FEED]

this will override the Modal setting and always output the
token value even if it has not changed.
