Arc Radius Errors

[TOwens777]

I have been recently receiving arc radius errors whenever I try to cut anything.  Even a simple rectangle profile generates it.

My post processor has worked well with Fusion up to this point.  Maybe a recent Fusion update is causing it.

The error is occuring here at Line 295 (N301).  I would really apprecitae any help with this!   Thanks!!!

On the post dialog you could set useRadius to yes to see if that works. Also can you attached to whole file, the file don't paste it into the reply.

Try reducing the tolerance for the toolpath to .0001" instead of whatever it is now.

What post are you using, I noticed the line you're having trouble with N301 G2 X8.8808 Z-0.04 I0.0126 K0.3748 is in the XZ IK plane and your file has no G17, G18 or G19 codes. Some controls work ok working with just XYZ IJK.

I tried reducing the tolerance to .0001 from .004, that didnt work. 

Here is the whole file.  I had to change the extension to .3ds before it would let me post it.  Mark, I'm using this post processor. 

My machine is a CAMaster Stinger I. I'm not super savvy with G Code so you'll have to please bear with me.

I'm not sure what you're referring to when you say use the post dialog to set useRadius to yes

Can you attach the post I don't think that's a generic one that comes with Fusion. I thought you were using Mach3, if you expand the Properties on the post dialog is the an option useRadius.

Do you have a PDF or any other info on the supported g-codes for your control.

Mark, here is the actual post processor and a link to a PDF for the controler manual. http://www.wincnc.net/webfiles/CNC%20Windows/Manuals/WinManual.pdf

It's too large to post  Thanks a ton for your help!

It looks like the winnc control only supports arcs in the XY plane, you could try setting AllowHelicalMoves to no. Really the post needs changing so you never get any arcs in the YZ or XZ planes.

Mark, where is that configuration window located? 

[TOwens777]

Nevermind.  I found it.  Mine looks different. 

I tried turning off allowHelicaMoves, that didin't work.  Any idea how I can get that post changed to omit the arcs?

Thanks!!!

I'm tempted to say buy a PC so you don't have one hand tied behind your back by Apple. Click the arrow next to Properties on the post dialog. Also try the attached post, I've changed it so it will only give arcs in the XY plane, it seems to run a bit slower though.

Thanks Mark!!!  I'll give it a whirl! 

I'm definitely getting a PC.

I'm cutting!!  That did the trick Mark!!!  Thanks!
