General Mach Discussion / Re: re : Mach turn ,tool radius index too big
« on: January 02, 2012, 07:23:18 PM »
Spindle speed averaging won't cause the problem as it only looks at 8  or so different rpms and then averages them
for the threading planner.

If you are trying to cut a thread and your axis velocity is not fast enough for the feed rate then the threading wizard will
warn you and not post the code. That is the reason i suggested you generate the code from the wizard.
 I didn't remember if the G95 wouldn't be activated though and that may be the case.

Didn't look at the code Hood posted.......you should have around 3 to 5 x the pitch in Z travel so the axis has time to accelerate.
Would seem that with a correct  rpm showing that you should get an index to start the treading.

What version of Mach are you using? ....hopefully somethng greater  than V3.042.32

everything seems to be working correctly spindle feed back and everything it just stops spindle stays running

Mach may be waiting for a number of spindle rev's to confirm the timing.
Debounce and index debounce can affect the indexing so maybe try different settings.
You can check the index by rotating the spindle manualy and when in G94 mode you will see the indicating light in diagnostics turn on and off.
Just generate a threading code via the wizard (we know that code works) and run without actual cutting. If the threading cycle starts then the 
those settings are not the problem.

Have you considered doing a spread sheet for each of the terms and then providing a link to good sources of information on the subject?

Dave,
Feel free to use the 19 pages for Arc Motion in the write up you will find in Members Docs.
For some items a simple definition just won't cut it or be of value without the understanding.

I don't don't see a sniper 50 cal in there Tweakie. It's important to be able to "reach out and touch someone".

I use two MPG's and in Config>Ports & Pins> Encoder/MPG's....MPG#1 & #2 are enabled, use the same port but use 4 different
pin assignments for the A & B Pin#.

Use dedicated pins for the X mpg?

Once you have basic understanding of how the scope works and is set up, it's limitations, then you need some experience using it along with the understanding of what and how you are measuring the circuit. Without the electronics knowledge background the instrument can quickly become nothing more than a boat anchor.
Trying to find missing steps cans really be a challenge, for instance, relative to software one would need to ask......

What am i measuring?
Is the software at fault, motherboard, port, something in between or along the way........
How do i isolate the circuit for sampling
Is my scope adequate to do the job......

So echoing what was said........... beyond the scope of this forum.
