General Mach Discussion / Re: I'm just a tease

HOOD,
I don't think turn will take a back seat.
Why it was just at the recent Mach seminar that Brian said major rework on turn
would happen over the next few months. That leaves only two more months to go.
But don't believe me, Greg, Vince, Dan, RC, and Brett all took the same similar note
on the subject.  
Brian thought we were snozzing!

Art,
The original threading code and the 17-2 version work fine.
Tried it out on two different lathes and three different PC's and coudn't get
the XZ moves to happen.

That extra line of G32 code is not skipped. It happens very fast and in a short distance.

For those following this thread, let me remark that the spindle slowdown can cause
the threading cycle to stop. The trigger point which causes the stop will vary depending on the pc,
but it is not no 10%.

Art,
Can you let us know when an update may get posted. Also will the update impact the SmoothStepper?

Brett,
Will the recommended pc requirements change?

Will it work on an older pc?

All for improvements, but.....agree with Peter's comments. An improved display isn't
worth a hoot if something basic is faulted!

Art,
With the changed code and the 17-2 version I CAN NOT get the XZ move to occur.
The threading cycle will stop at around 75% turndown ( 100 down to 25 or 30  rpm to trip it).
I could "very rapidly" stop the spindle ie; 100 rpm down to 0 only for less than a 1/2 sec or less
and the thread cycle would continue on.

I tried to spike the index pulse by varying the rpm numerous times during the threading and stiill the threadiing continued.

The displayed rpm is off in the readout and also in the turn diagnostics by about 5 rpm ( 95-96 vers 100 actual).

------------------------------------------------------

Now i need to replace the first line G00 back to G32 and see what happens.

------------------------------------------------------

One thing i did notice is that if you vary the speed it may keep that speed for a few thread passes.
As compared to a 5 months ago, the Z dosen't seem to be as reponsive to a slow down or speed up
of the spindle.  But lets not dwell on that for now.

Think your on the right track!
I'll fool with it more tomorrow as it's getting a little late.
Will stiick arorund for about 20 minutes of so.

Answered my owne questiion in the last post #153.
Here is the code i am using for testing with *********xx17-2 mach file.
First line of g32 code changed to a G00.

Looks promising, but let me fool around some.

ART,
It's not the double line of the gcode. I generated a different Gcode with just a single line of g32
coding. Same problem.
I will change it.

Just a quick question, is the *********x17-2 file strictly for use with a PP? ( the other one would not work with
the SS). That other one would also generate an error if you tried to use the gcode posted in my reply #117?.

Hi All,
Has anyone tried the latest version 3.042.023?

I still get the same XZ move and now there are actualy "two" of them instead of
only one. That was with G32 and using the SS.

Art, send me the special driver when you get it done.
