Code G03 has error, output of P instead of R on the radius

Code G03 has error, output of P instead of R on the radius

I am getting an error with radius for G02 and G03 codes.  When I make the cuts and simulation everything looks good, but when I post process thats when thing go bad.  For the program settings i turn ON radius and turn OFF write machine and OFF for write Tools.  so when im looking at the script the Radius in the code is the letter P and not R, so i manually change all P's to R's and then i get an error says start and end point of X is the same, like it doesnt post it,  here is an example of my error for the P:

 

G17 G3 X-0.3454 Y1.0495 P0.0114
G1 X-0.3377 Y1.036
G2 X-0.3574 Y1.0248 P0.0114
X-0.3589 Y1.0304 P0.0114
G3 X-0.3707 P0.0059

 

when i turn, use Radius off this is the error i get: K work given for arc in XY plane, whether G02 or G03

 

G1 Z0.0962 F8
G17 G3 X-0.3283 Y1.0265 Z0.0932 I-0.3449 J1.0452 K0.6001

 

I dont get why its doing either of errors and i dont want to have to manually change this every time.  What is program is is part of a TEXT that is exploded and extruded so i am not doing anything special.

I'm thinking this might be something else entirely different from a post issue.

 

In addition to the info that @daniel_lyall has mentioned, please export and share your Fusion file. To do so:

File > Export > Save to local folder on computer. Return to thread and attach the .f3d file

Hmmmm I dont understand what you mean by, what post processor i am using.  i am using the post process thats built into Fusion 360.  all the settings are default except for the write machine and write tool.  i have been switching between using radius being ON and OFF but have been getting problems with both settings.  i am new to this software but am well experienced with other CAD softwares.  i have attached a screen shot of what i am looking at, is this the post process settings screen you are talking about?  i need help on this issue.  thanks

By "Post Processor" we mean just that. In the Post dialog, there is a menu you can click on that will give you a post processor specific to your control. If you are using a Mach3 control, for instance, you would select that Mach3 post:

Looks like he's using the Acramatic post. 

 

@Anonymous Do you actually have a machine with an Acramatic control? That post outputs radius values with a P word, so exactly what you're seeing, and it's supposed to.

You where useing the wrong one the Mach3 post is in there just hit the drop down button and scroll down to it, And that one you can only use Radius for Half circles up to 180, if you need to go over 180 degrees you have to use I and J.

Any questions just ask

Actually R values can create an arc error if the start point is off even a couple of tenths. The bigger the arc, the worse interpolation will be. This has been documented in 2D Contour with roughing passes in all three packages. You're better off using IJK amd post updates reflect this suggestion if you look at the notes on the post library (see the Haas post as the easiest example).

THANK YOU GUYS for all help.  I chose the mach 3 in the post process.  I didnt that area was able to change since it was grayed out.  I guess I should have clicked on things even tho its gray.  Code is correct and no more deleting anything in the G-code
