You could use a planer gauge  as a Z =0 reference such that if you machined the original reference you still have a
reference to go back to. Actualy you can use anything as a reference since your manualy adjusting. Everynody works a
little differently.

General Mach Discussion / Re: Turn G Code

« on: August 23, 2010, 06:28:32 AM »

but I am stugling with the lathe, as I find Lazy Turn complex to use

There is a manual for LazyTurn which explains everything about the program.
You provide a dxf drawing of the profile,define tools, use that tool to do a rough cut, then a finish cut
and finaly post the code.Look at the appendix's as they provide additional information to the lathe user.
It's a slick program and a lot easier to use than some of the higher end ones.

You can get the profile code from LazyCam Turn and the appendix tells you how but LC Turn is
not as easy to use.
Keep at it you'l get on with it ............

You may try unchecking spindle speed averaging  and see what happens. I always have that on and may not make any difference
anyway if not threading. I just tried turning the spindle by hand and my DRO was reading  down to 3 rpm ( kind of hard to get constant turning by hand).

My index debounce is set at 10, can go lower but works fine there for me.
Don't know what else to suggest.

jaja,
That was fixed in version 3.042.032, .033 or so. You are required to turn the spindle on with a M3/4 and that also tells Mach to start looking for
the index so low rpm's would show. Did you try a different / lower Index Debounce setting?

I don't know, but then I would use the screen Phil posted as it works.

What happens when you use the standard screen?

Mike,
Actualy for turning you may want to try LazyTurn. Will not provide a profile cut but the rest works.
I am lazy......
