Lathe Macros

Yes 2mm depth of cut (diameter mode). And yes their was a constant diameter variation on all cuts, with a huge taper on the last cut. Weird behavior.

Mark - watched it again and the only thing that comes to mind is that it appears you've got G64 set with no P value.  I don't know what preamble you've got in your INI file and the macro doesn't show up in the g-code window...

Maybe the unconstrained path blending is hosing things up?  Trying to blend the straight section with the lead-out?

You could do an air cut with G61 set and watch the X-DRO and see if it moves the same way.

Hmm, thanks for noticing that. In my CAM PP I have a standard G64 P0.1 in the header. I'll add the G61 to the start up file.

I was out watching Oppenheimer yesterday, but will try a G61 on it after work today.

You nailed it Spumco.

I am using 3 digital pins for my temporary control of back gear, variator up and variator down. Looking back in my MDI, I screwed up and tried to do a variator speed change with G64 P2, rather than M64 P2. I remember doing it, but didn't consider the consequence at the time.
With a 2mm tolerance on the nominal tool path, it is no surprise it was cutting those tapers.
I already had G64 P0.1 in my Ini file.
Thanks for your help.

LCNC should have known what you wanted and not cut the taperimage missing /media/kunena/emoticons/wink.png


PS: I can't wait to see the Schaublin blasting out parts with the tool changer and a bar puller.  You've got enough X-travel that we could rig up a pneumatic part flipper to do backside work for a one-and-done operation!

Thank you for the entertaining and educational vids. 

I am struggling with constant other projects becoming sort of urgeant, so the Schaublin progress is really suffering. I really need to make the control panel for it, and then get on with stripping and cleaning the tool changer. I dont see a bar puller in my future, but who knows.
