The capacitor formula in reply#16 is a standard powere supply formula you will find in most electronic books.
The capcitor size found from the formula is a value, which if used, should provide you with DC ripple
to less than 10%. So less cap maybe more ripple in the DC and likewise more cap less ripple. So it acts
as a fiiter.

As far as steppers running hot....I don't like mine running above 120F ( my preference only )
80C  and above you can burn yourself and they should be guarded from a safety point of view.
Yes you can run them hotter. Motor winding insulation is one limit on how hot you can get them.
I know that if the temp gets to high they will start acting strangely.
Then if they are only warm, the motor isn't working to it's available potential.

The "ticking sound" ........you realy need to take a look at the generated pulse signal out of the
PP port and see what it looks like. If you have ringing or whatever on the signal out of the PP it can
create all kinds of problems. The only way to clean up a pulse signal is deal wiith the source of it.
If you can't find that source and cure it.......nothing downstream will clean it up......from trying homemade
clean up circuits / break out boards / different PP card , if it's generated by the computer before the PP,
they will probably not work ( my experience and what other knowledgable people have told me).

One solution is to have the pulse provided by using the SmoothStepper.

Just some info for your consideration as i think your not having much fun!,

Brett,
You are exactly right.
Dan put one on his machine and it's realy neat. But like you said, you are not thinking in terms of
the right hand rule. Additionaly, if you use a video camera the image is reversed and it dosn't feel
natural to your senses. So there's more than just the stated reason and think it would a worthwhile
option to have available.  ( better than taking the stick apart and changing the wiring!)

GREG,
Right on! CopyCat could become the wizard tie-in along with is current good feature.

Hi Ron
Here are some comments / suggestions and others please chime in.

1.SCREEN - would be nice if some of the buttons were moved around
                   such that the video screen had its owne place when opened.
                 - maybe increase the other window sizes
                 - a real rough screen showing this is in the attached file

2.Is it possible to have a "delete" last move button. Once you start an
  arc you need to complete it. ( you can edit the code but i am lazy )

3.Full Circle - darned if I could get it to work " per the help info". Still wondering if it's even needed.
                    read other comments below. The light never comes on , but,...you will see that you
                    clicked the full circle if you look closely at the box.

4.Bug? - If you do  a linear / rapid move and then an arc then forever you can only do arcs and line.
             If you do a linear / rapid and a full circle then forever you can only do circles and no arcs.
             Seems like a broken switch in the code.

5.Probing - YES a nice feature worth doing. If you look at the "videos" there is one showing an automatic
                 centering routine which is realy slick. Don't know what Ron has in mind. Depends on how
                 you do it.

6.THE BIGGY - The first questions is........What do want copycat to do or go as a program?
                 It would be slick if you could go to another  wizard  and pluck their generated code at any time.
                 Thus if you move to a point and if you want to do a circle, drill routine, etc just click a button
                 and you could get that code and paste it to the the teach file and continue on.
       
                 Sounds easy, but.........

                 Currently if you want to do the above :
                  While in copycat, edit file, then open another file generated by a different wizard, copy / paste into
                  the copycat / teach file, save............BUT......need to edit the pasted in file some.
                  May be better to just add a comment at a point.

 So if you had the above, CopyCat now becomes an even more very powerfull tool appealng to users who may
brush off using it.

Vince,
Did you try using the full circle?

HI All,
Just a dumb question.
Is it possible to change the x / y direction on the joy stick such that it will  move the axis opposite to how the machine is configured?

This one is done with a different tool and the latest version.
See comments.
What can i say, back in training!  ;)

Ok, just tried the newer version. Same figures in last post #837 apply.
So now in the tree i see no volume was removed from the end volume.

Thus, until it shows that the tool volume was removed it still is a now go?
Bear with me, don't want to spin my wheels once i start going thru a whole bunch of files.

Art,
Lets see if my understanding is correct. The attached shows three different senerios all with the same tool settings except for the numer of scans done.
_1_  -  RESULT OF 1 TO 5 SCANS
_2_  -  RESULT OF 6 SCANS
_3_  -  RESULT OF 9999 / SCANS

So how do i interpret?
