Powermill LinuxCNC Post

What exactly do you need to write?

1) You need to make virtual model of your cnc machine and to adjust all axes.
2) You need to import (connect) your model to postprocessor and to modify post for your special cases.
Then your can work with it and to make G-codes.

Posts for mach3 also suitable.

this is Clear to me
But where is the File that holds the Connection to the Virtual STL files
i did not find any Machine in the Installation of Powermill
This is my Problem I got all Axis connected Parts Separated and Downgrated to get a Sharp clear
Machine Model
i did add the STL files here
if i setup a machine / RENAME from a Example it ads about 100files pmlet and a MDdata folder
there is a File that seams to hold the geometry as a XML but no guide or info on how this is syntaxed

THANK you for your help
If there where a Example im shure i coudt do it
and safe the School lots of money as they fine 1kEUR Post costs

From your last messege I understood that you are know nothing about PowerMill post processors and their machines.
Also I know nothing about your problem and your machine, except that you need 5axis post.
Try to read PowerMill documentation to understend right way:
MTD user guide
Build Robot simulation in Powermill

PS
PowerMill doesn't work with stl-files, only *.dmt

Thank you Sir i will make DMT right away and start reading the guide

Maknig progress as Corona timeout sets School off time 5 weeks lots of time to get Software setups
here is the image of powermill with the ,ashine flow
also added the DMT full file folder with the MTD file
The instruction sying you do not need a postprocessor but the NC out asks for the OPT Pmoptz File to be created

Good job.
I didn't understand, Powermill doesn't need postprocessor?
