X0.0001 is to long for Heidenhain
The one micron in metric is 0.001

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?

I'm not sure exactly what you mean. Which circle needs to be duplicated?

Place where I mark red lines is diferent color, material to take out.

HI Les
I check code in machine made in 2021.
Simulation give error : " circle wrong programed "
Is it possible to change accuracy of math calculations to exactly 0.001 without something more....

At the moment the resolution is set to 0.0001. Edit the post and do a search and replace. Wherever you see 0.0###, change it to 0.0##

Yes. in the post is 0.0001.
What about calcuating in sheetcam. Is it the same accuracy?

Internally SheetCam calculates to a far greater accuracy than 0.0001".

Thanks Les.
I tried to figerout how to fix this bug, because i can't use pocket operation in my heidenhain.
TNC do calculate from point to point, there is no place for mistake.
Last year I wrote:
The start circle point after plunge arc (CP IPA-196.648 Z-6.000 DR-) has to be exacly in the same point.
On some shape the Post calculate 0.002mm mistake. The last circle is little, about 0.002 mm long, maby less.
Machine do little arc and do not go around as should.
I don't know how far is heidenhain accuracy. 0.00001 or 0,00000001.....
I post same program but diferent accuracy:
1. 0.001
CP IPA-196.648 Z-6.000 DR-
C X+36.471 Y-29.967 DR- R0 F200
2.0.00001
CP IPA-196.64828 Z-6.00000 DR-
C X+36.47065 Y-29.96732 DR- R0 F200
Could You look again to this. Especially on C X+36.47...
