Hi,
While using radius compensation, I've been getting two errors:
-“Gcode Error concave corner with radius comp”
-“Cutter gouging with cutter radius comp”
I assume this is related to the default EMC/NIST entry move style, so I would like to set the Fanuc radius compensation entry move style. I followed the section on the wiki to enable this style by adding the following line to the Kmotion CNC setup file:
comp_entry_style FANUC_COMP_ENTRY_STYLE
Now I'm getting the error: "Unknown attribute comp_entry_style"
I'm using Kmotion 433
Am I missing something here?

Re: Fanuc Radius Compensation
I've installed 434. The installation on a new machine did not go smooth. After installation I got 3 errors:
-" The code execution cannot proceed because mfc140d.dll was not found. Reinstalling the program may fix this problem."
-" The code execution cannot proceed because VCRUNTIME140D.dll was not found. Reinstalling the program may fix this problem."
-" The code execution cannot proceed because ucrtbased.dll was not found. Reinstalling the program may fix this problem."
During installation the installer prompted me to install something from Microsoft (forgot what) on which I chose "yes". So I was surprised that there were dll's missing. Anyways, I searched the web for these dll's, found them (https://www.dllme.com) and put them in the C:\Windows\SysWOW64 folder, after which KMotionCNC started without error.
Then I chose the default settings file "C:\KMotion434\KMotion\Data\Default.set" and added a single line to the bottom "comp_entry_style FANUC_COMP_ENTRY_STYLE". I restarted KMotionCNC to be sure the settings are loaded.
The good thing is that the error "Unknown attribute comp_entry_style" did not appear anymore. However, after that I tried to run my G-code that uses radius compensation in simulation mode. This did not work. I'm still getting the "concave corner with cutter radius comp" error. This is the small test G-code that I'm trying to run. Tool #1 should be set to 5mm diameter.

Re: Fanuc Radius Compensation
Hi BaxEDM,
Sorry you had trouble. Those are all Debug versions of Visual Studio libraries and should only be needed when trying to debug. Maybe you were running from the \KMotion\Debug directory rather than the \KMotion\Release directory? BTW you should be very careful downloading dll's as they are often infected with viruses. So only download them from Microsoft, Dynomotion, or someone you completely trust.
The radius compensation seems to work ok for me. Here is a tool path plot of your GCode with comp for a 5mm diameter Tool.
Here is a double plot with/without compensation. "Without" comp was created by setting the Tool diameter to 0.001mm (Tool image diameter is still 5mm)
I've also attached the Settings file (as a txt file) that was used.
Any special offsets or other settings you are using?

Re: Fanuc Radius Compensation
Hi,
Thanks! It works now, not sure what I did wrong though, might have navigated to the 433 settings file while I changed the 434 or something...
Regarding the dll's, I was running the Debug exe indeed, my mistake, I removed the dlls and ran the released version without problems.

Re: Fanuc Radius Compensation
So I had the same issues and am using a Fanuc style post I believe. I was glad to see this post and was able to download the setup file that Tom posted which resolved the gouging and concave corner messages for me.
However, now I have constant errors with G03 moves, each one popping up with "Tool radius not less than arc radius with comp."
Am I missing something else? Changing the post processor is possible but not as easy for me to do as working with KMotionCNC if there is something easy that I am just missing.
Below is a short test example of code - it is using a 12.7mm endmill with an actual diameter of 12.72mm that is stored in the tool table. Let me know if you have seen this issue and how is best to resolve please... Appreciate the help!

Re: Fanuc Radius Compensation
Hi a_j_p,
It isn't clear to me what you are trying to do. Are you trying to cut pockets or leave material standing up.
Here is a plot of the GCode with no compensation which should show how the material should look after the Job runs.
Also shown is a tool with diameter 12.72mm.
If you are trying to cut pockets the tool is too big to fit in radius.
If you are trying to leave standing material the tool will gouge the adjacent material.
What are you trying to do?

Re: Fanuc Radius Compensation
I am trying to cut bosses, the first image attached called 'boss outline and setup' should hopefully explain. The second picture called 'centerline' is a centerline simulation in the software I use (FeatureCAM) showing the finish pass (same as the G Code I posted earlier) but it also includes a wireframe outline of the tool, which does not gouge any adjacent material...
I have not used cutter compensation before now, I have not had the need to do so until recently, so it very well could be something I am doing wrong but I have been trying to figure it out for a while now without much success. It is pretty difficult however to get the FeatureCAM guys to support when the machine is not something that has a manufacturer's manual they can follow along to make post processor adjustments. The post I have from them is based on a Fanuc system with only small changes to add custom M Codes that I can have KMotionCNC execute specific items with.
If it helps at all, below is the same file's G Code post with cutter compensation turned off in FeatureCAM. I have used this file to run a part and it works just fine, just without the cutter comp...
Again I appreciate the help! Let me know if there is anything more I can provide, etc.

Re: Fanuc Radius Compensation
Hi a_j_p,
Thanks for the information.
It seems the specified paths in your GCode in both cases (with and without compensation) is exactly the same.
Maybe the confusion is that there are basically 2 approaches to Tool Diameter Compensation.
#1 - is where the GCode specifies the final result without any compensation at all. In this case the Tool Table entry contains the true Tool Diameter of the tool and the GCode Interpreter does all the compensation.
#2 - is where the CAM software does all the compensation and specifies in the GCode the tool path based on a theoretical tool diameter. In this case the Tool Table entry contains a small +/- difference between the actual tool diameter and the theoretical tool diameter used by the CAM. The GCode Interpreter then makes only a small adjustment to the tool path to compensate.
Do you understand the difference? Which approach are you intending to use?

Re: Fanuc Radius Compensation
Hey Tom,
I was planning (at least in my head it seemed the easiest) to have the CAM software setup with the theoretical/nominal tool diameter and specify the end result. The Tool Table would contain the actual tool diameter and the GCode interpreter would offset itself half the distance of the diameter in the tool table to yield that end result.
If I understand what you have written correctly, I believe this would be your option #1.
Is that not what I am doing?
Again, thanks for the help!
