I changed it and you're correct as it clears it up.

Am I not allowed to be in diameter mode? So now is this because it was the way it was drawn ?

I'm not understanding this at all. :-[

All fixed  :)

You can spot my new exit line for the x/z that needed to be fixed as well ;)

I still have no idea what I'm doing. I'm going to have to seriously sit down for some time with this to really try to understand what it is I'm doing.

Hi all,
So here is my concern with opening the file in MachTurn. I think this is a good example of "state of confusion".

You don't know how that file was created ie; mm / inches?, diameter / radius?, incremental IJ / absolute ( Lazycam posting setting GCODE FILE OPTIONS) , what side is the toolpost ( reversed arc's in front tool post ), didn't close the file and load it back in after changing a setting in Mach ( sometimes it seems like that changed setting didn't take place), possible Distance Mode & IJ Mode combination of settings in MACH ( you'll get errors ), lathe object dosn't appear "exactly" as you would expect ( we know it may not be exact, but then suppose the tool definition in lazycam wouldn't allow for full cutting of the profile so the you get a play on the lathe object in the screen).

Now it's true that the person generating the turn part would pick up some of these. But if say a newbie, and starts
to play with code (hmm......good grief.....). "State of confusion".

I quess i don't have an answer to what is reflected by the above other then experience.
Maybe some info like "here's what can wrong"  in the manual would be worth doing.

Now when you leave Mach Turn after fooling and restart days later .......how's your memory on the settings?
Take a look at the recent ABNORMAL CONDITION THREAD.

May be getting of thread here, Spnar is forgiving  ;D

Dave,
Good question about the turning mode.
I get the cropcircles if it's brought in when configured for diameter mode.
If it's created using radius then you need to use radius mode.
You may be able to scale it Lazcam using the SCALING tool before posting the gcode, but ,
with out some remark in the code it can get confusing real quick.

Look at page 5-9 in the MACH III Turn Manual it talks about the modes. BTW you really can in trouble quickly as some programs only generate code in one mode or the other.

Here is my screen shot of the file in mach turn. Note where the arrows are pointing, which was a concern
in my previoius post. Don't know why its not like yours. I didn't change the xz move.

Hi guys

I have been thou all of that plus a female computer with a
mind of it's own.
The J word problem is solved just as RICH described and the circle stuff
has to do with the tool parameter setting in Lazycam.
If you compare the profile you have with the actual DXF file it has
a lot of detail missing. I am assuming the tool profile and or
penetration are not right.
