Turning post with "diameter"-mode off

Anonymous — Tue, 24 Jan 2017 15:38:54 GMT

I've run into a problem figuring out how to output turning toolpaths with real, physical axis coordinates. Powermill post seems to default to the "diameter" mode, where the X-coordinate is interpreted as x*2.
I find this mode of operation unacceptable, and want to get powermill post to output the X-coordinate as the true x, and not x*2.

Is there some parameter that can be changed to inform the post of this? I'd prefer not to have to do a manual switch based x/2 correction.

Could not find any other way, so super dirty fix:

At the start of the move commands, add a if with %p(Process Type)%=="TURNING"

with output to tape off, X=%p(X)%/2

Then just the regular xyzbc etc. line stuff.

This also needs to be done for all added approach moves that use the CLDATA X values.

I would really prefer a flag to turn off the "diameter" mode.

The Diameter mode parameter is just a raw parameter without any defined states or attached script. No difference will be in the output by initializing it.
