You need to change your post processor output.
I assume you are using format 2 and I believe RhinoCam pro is the same as VisualMill.
In your post processor under "circle" change the output to IJK only and Set Vector from start to center.
Give this a try.
I had the same issue with the default post.
MecSoft has a support forum as well for your future reference.
I believe the parameters are also changeable in the MC under SetP but the post changes should do the trick

i did see it was putting "r" values in after i and j but figered the guy making the fadal post for visual mill knew somthing i didnt,lol.rhinocam is the same as visual mill just bundled with rhino.thx about the visual mill fourm i did see it but figered id post hear on fadal cuz you know what a fadal post is supost to look like.. thx ill try that i did see the settings in the post editor

what is format 1 and format 2?? is this a setting on the vmc or in my cam?witch is better?

[DareBee]

Format 1/2 is on your machine control (I assume your 80s vintage 88HS is like my 90s vintage).
Format 1 is "Fadal" format and format 2 is "Fanuc emulation" Format.
Most people I know use format 2, there are a few people on this forum who do use 1 though.
To change formats go into SetP and it is the first option.
Read your operater manual, they are available online as well.

in setp there is no mode option the first option is travels?? whent threw all option and it wasnt there?? maby the old -1 system only has one format?? if it is only format 1 / fadal is my posts going to be the same?

The post looks like format 1 but the K and R values are strange. Should just be I and J when in g17. Try getting rid of the K and R words and see what happens. Everything else looks fairly normal.

[chrisw765]

well i set the post for i j k only and set fron start to center, when i backploted it gave me the big old circels wher ther are to be arcs,i didnt try it on the fadal, i changed the post to from center to start and it back ploted perfictly?? but then again the orignial backploted right but gave me crazy big circel on the mech so?? how will the old fadal read it?? will see any ideas would be helpfull?? hear is the new and hopfull last g code removing the r's droped it by 1k so its down to 3k

Chrisw765,
If I remember right, there are 3 pages of parameter settings for the 88 controls. You probably just looked at the first page. It is the one that contains the travel parameters first. Hit the space bar to get to the next page, if I remember right.

[chrisw765]

whent threw it again and it isnt there ?? i whent threw each page i did see my defalt baud rate was rong so i changed that but no mode 1 or 2 my software is 86.2v pretty early but works like a charm??

If you are using IJK values dump the R values. IJK values are measured incrementaly along the axis from the start of the arc to the center of the arc. If you are starting at zero on one axis you only need to define one value. Example: tool is located at x.5 y0 and you are going to x0 y.5 you would program g3 x0 y.5 I-.5. This will produce a .5 radius arc about x0y0. Don't forget tool comp.
