Re: Heidenhain Post doesn't work
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.

Re: Heidenhain Post doesn't work
I have test again and again and:
CP IPA-1.620 Z-0.250 DR+
CP IPA has to be the same sign as DR every time
I checked this on Heidenhain Book as well

Re: Heidenhain Post doesn't work
I think I found the issue. The IPA angle is the wrong way around. Give this version a try.

Re: Heidenhain Post doesn't work
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.

Re: Heidenhain Post doesn't work
Is it leaving material on both passes or just the last one?
Re: Heidenhain Post doesn't work
Last one.
It is strange because when i change tool to 8mm then ramp to 4 next to 5 degree. Path is ok.

Re: Heidenhain Post doesn't work
I can't see anything obviously wrong but give this version a try. It only uses 'CP' type arcs.

Re: Heidenhain Post doesn't work

Re: Heidenhain Post doesn't work
I'm not sure what is going on here. Does changing the ramp angle have any effect?
Re: Heidenhain Post doesn't work
The angle Doesn't mater. All circle is diferent.
Size of this circlres depends from step over percent, when change the size is change as well.

Re: Heidenhain Post doesn't work
Previous post was ok but, why on 2,5,7 ramp angle path is ok.
on 3,4,6,8,9 angle was problem with path.

Re: Heidenhain Post doesn't work
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:
1. code is ok
2. code not do circle on last pass
Is it possible to round calculations to maybye 0.005 mm

Re: Heidenhain Post doesn't work
Ah, that explains a lot. In SheetCam go to Options->machine->post processor and click on 'Edit post'. On line 19 you should see this:
change it to:
Code: Select all
numFormat = "+0.000"
Code: Select all
numFormat = "+0.0000"
