Deleted, wrong info

Hood,
 Looking at bills code:

G40 G18 G80 G90 G95 G97 S400 M03
G00 X0.525
G00 Z0.1
G00 X0.5
G76 X0.4 Z-2 Q1 P0.05 J0.006 L45 H0.022 I29 C0.025 B0.0001 T0
M5
M30

There is are no G95 feed moves....only rapids and the G76 cycle.
Regardless of the spindle speed, I would expect the dro to be constant at .05
Will check back later.
Thanks,
RC

Sorry RC, getting late here and not comprehending fully, I was assuming with the initial mentions of of the different spindle speeds and feeds were just when doing G95 and not in G76.
Sleep time, heads screwed up worse than normal (so it must be in a bad state )
Hood

Take care Dude....you're on overtime.
Rest well,
RC

Hello Again,

Can anyone explain the G95 mode DRO varying according to differences between programmed and actual spindle speed.

I thought I built a lathe that can do threading and right now that is the only thing it does not seem to do.

Let me know if there is an explanation.

THANKS,

Bill

What is the problem you are having with threading?
Hood

Hello Hood,

Well I tried out the program previously listed in this topic and actually cut a thread.  What I discovered was, as long as the programmed and actual spindle speed matched it cut a good thread.  When the actual spindle speed was different even slightly it ruined the existing thread I previously cut when actual and programmed spindle speed matched.

I was talking to codemangler and he suggested trying a macro that could read the actual spindle DRO and insert that into the program as a programmed speed variable that could be constantly updating itself.

Does that seem to to be a logical approach to you?

Bill

Are you using the Demo? What version are you using?
Threading works well and the Z Axis will track extremely well to changes in spindle speed. There has been a problem seen recently by some where there are big slowdowns in spindle speed during a cut, the X axis will start to move. Art is looking at that one to see if he can find it.

Hood,

Well, it is amazing what a little thing like a license can do to solve all my threading issues.  What happened was I reloaded Windows and Mach to clear up some freezing up problems and did not put the license file back in the Mach Directory.  I do not know how that happened, but the version is 2.45 and it is tracking superbly now. 

I appreciate all the support, thanks you all especially Hood. 

I feel like the guy who just didnt plug the darn thing in.

Been there....Done that.
It's easy to overlook the obvious.
Glad you're up and running Bill,
