Hi, All.

Why this program is not working? All data in mm. Mach3 and some other programm working with no problem.

Best regards, Alexander Kovylkin.

Hi Alexander,

The error message is quite explicit

"G Code Error

K word given for arc in the xy plane"

the problem occurs on this line (first)

N45 G02 X55.000 Y-57.500 I-2.500 J0.000 K0.000

the last parameter (K0.000) needs to be removed.

Hi.

The error message that I have not such as you pointed out,
and "Concave corner with cutter radius comp". The problem
is that almost all of my programs which use G41 and G42 give
this error.
For example, I attach another program.
T1 Finger cutter diameter 16mm
T2 Finger cutter diameter 12mm
T6 Disc Cutters diameter 120mm thickness 4mm

Alexander Kovylkin.

I added a single R parameter to the line that was indicated as being at fault and it works in KMotionCNC, see screen shot attached.

Not sure what you have set up differently to see different errors but it seems that your post processing is not perfect.

Sorry I see the problem now but I not sure what you need to do.

Hi

Unfortunately, I can not influence the post-processor. I hope very much for your help.

You can describe in more detail you added R parametr?

Best regards,
Alexander Kovylkin.

Please send me the corrected file proba2.tap. I've never been able to run it in the simulator.

Alexander,

I suspect that the problem is regarding RELATIVE or INCREMENTAL coordinates for the ARCS.

KMotionCNC assumes that the measurements are INCREMENTAL (FOR ARCS). G90 is separate.

However I am sure Tom will be along later with a full and proper explanation.

best,

Jon

Hi, Jon.

When can I get advice from Tom.

Best regards,

Hi Alexander,

I think the main problem is that there is not an "entry motion" into the desired cutting path that doesn't result in a gouge into the path. Basically an angled left turn in the defined cutting path with the cutting tool compensation on the left is not allowed (or possible). Some systems either ignore this attempt to insert an arc for you. But this usually only works for the simplest of cases. If the segments are short the result can be bad or unpredictable.

Also arcs in the xy plane do not allow the z coordinate of the arc center (K word) to be specified. You will need to remove those.

I've described how to add an entry move for your job in the attached document.
