could you send me the job file (File->save job) used to create that code. If you don’t still have it, set up a simailar job then post process and send me both the g-code and the job file.

It is much better.
Next problem is when i change Ramp Angle. Look at the pictures.
When put 3,4,6,8,9 angle machine leaves material.
When put 2,5,7 angle is ok. Untitled.job (6.93 KB)

Hi Les,
I think i found the reason of the problem.
Heidenhain work to microns. The start of the circle after plunge CP IPA+… Z-… DR+, the last circle “C X+… Y-… DR+ R0 F1500” have to be exacly the same point.
On some shape the Post calculate 0.002mm mistake. The last circle is about 0.002 mm long. Machine not go around.
Could You look to this calculation.
I attach two tnc programs:

code is ok

code not do circle on last pass

Is it possible to round calculations to maybye 0.005 mm 1.h (3.57 KB) 2.h (1.93 KB)

Hi,
One year ago we tried to fix the Heidenhain Post Processor TNC 410. Now i found the way.
Last circle on ( endZ ) has to be repeated do take rest of material.

Please look on pictures.
Coul You add some lines to post?
