Title: LATHE: TOOL PATH SCREEN: APPEARANCE OF STOCK
Post by: jshank on June 11, 2009, 07:14:06 AM

Hi,
I have just started using turn and have a current version loaded.  My question has to do with the tool path screen.  What controls the appearance of the stock?  On my screen, the stock does not appear or coincided with the tool path.

Can you post your code or a screenshot of what you are seeing.
Turn needs a fair bit of work, its never really had much attention in the past as people with lathes have been in the minority. Having said that, after Brian gets the new rev he is working on done he will be moving his attention to turn.

Jeff,
What program are you using to generate the code?
Can you post the DXF?
I can't find a setting that will get the stock to show properly and have seen similar before.
I have just ignored the stock at times by turning off the setting in config>toolpaths, not saying that is appropriate.

Rich,
I used BobCAD v23 to generate the code, first drawing the part in AutoCad, then importing it into BobCAD for the code generation.

It just looks like one of the problems with Turn, hopefully the revamp will get done soon and things will be well. Why some files show correctly and others dont I have no idea.

Sorry, just a user like yourself and don't know why.
I usualy do a final  finish / profile coding ( which the posted code dosn't seem to have ) and then maybe it "may" show correctly.

Until whenever, as long as it cuts the way you want it to.  ???
