Maybe when I add the audio to it. Heck I may as well include using the pp and show the mach end of it also.
BTW, I did make one with audio, but the boss was giving me some guff, made me screw it up some, and my recorded
comments were past the adult supervision warning.   

The licenses work on both machines, so if one generates a request make sure that your  security is turned off.

Dennis,
I made a video on the three balls  from importing the dxf to machining the profile.
Send me a PM with your email address and i'll send it to you. The next one will have audio.

General Mach Discussion / Re: Possible new project pending feedback on LazyCam software

« on: August 16, 2012, 06:10:06 AM »

There is  a manual for LazyCam in Members Doc's. LC is what it is and the developement stopped a long time ago.
Yes it is easy to use,quick if you can provide a good dxf for import to it, but it has it's limitations and more for hobbiest use.

Your in buisness and you will probably grow out LC  and echo what Ray posted. There are others that should be considered.
So you need to think not only about today but the future.
No matter what software you choose you will have a learning curve. 

Your software investment is just as important as your machine investment so budget for appropriately.

Dennis,
I'll get Mach3 diameter & radius post processors posted on this site for your use with V11.
1. You need to have Mach display properly using what was posted.
2.Then when 1. is working, you will need to learn a few things in Dolphin CAD so you can create a proifle for use in the CAM.
   Dosen't work like V10 did.
   I will post a how to do that including adding the pp's to the program.
3.With the CAD working and the pp's installed, then you will need to learn how to use the CAM part. Let not your heart be troubled
   as i will post another example how to.

Dolphin is working on updating the site to have new pp's for V11 available for downloading and new documentation. Should you get bored,
search you tube as there are number of videos which one should watch very carefully.  

Remember that this is all fun,  
RICH

Jim,
Just a comment on the Quick Threads Wizards, if you use the thread calculator to find the depth of a sharp vee, be aware, that the depth is WRONG
in that calculator.  Sharp V depth is  equal to 0.86603 x Pitch.

Frankly I like the standard wizard ....but to each their owne.......Pappabear did a nice job on quick threads.........

Dennis,
The xml I posted in reply #96 works and brings up the standard lathe screen set. So if you do nothing other than just load the program posted in reply #73 it will run and the path shown is correct.

You absolutely need to have your xml correct so you know what is being portrayed is correct, and if not, you probably did a booboo in Dolphin.
I will echo again, IE; Draw in diameter, configure Dolphin for diameter, use a Dolphin diameter post, have Mach configured for diameter. Do not mix diameter with radius anywhere along the way. KISS applies 

I am still waiting for my license. I requested a pp for radius and diameter but as provided they did not work for V11. 
Not sure what they sent you Dennis...read on.

Hood,
Thanks for the pp mod as it worked for both of the V10 pp's for use in V11. I looked in the manual and there is not crap on what to do.
Now I want to just confrrm that they  post correct pathing to have confidence in them ( so far so good   ).  Also got the CAD import to cam profile
creation down path, hey hey , amazing what one wrong click can do......

Jim,
Quick Thread screens can be found in MACH SCREENS>FINISHED SCRENS, just go down the topics and you'll find it listed .

For a video you may want to try a search on You Tube.

General Mach Discussion / Re: Spindle Motor is the cause of all my problems

Shielding is a rather diffcult to put in simple terms but I will try and confuse .....
 
The shield is nothing more than an barrier to keep something out, something in, or take something away.
The barrier can be solid, like a metal wall, or it can be open, like a fence and still act as barrier. Thus electrically
it can be 100% or less. It can be open, and be effective, but the actual opening size is frequency related.
The best shield is 100% as it totally shields what is inside from what is outside and vise versa. Additionally it can can conduct.
So what happens to the shield at the ends is important.

If one end is connected to ground and the other not connected, then it acts as shield along it's path but additionally it conducts
and provides a path for signals to the ground. It won't  transmit all signals since depending on it's length is acts as a short to
transmission.

Shields are normally taken to a single point and that point goes to ground. Ground is not ground. Ground is just a reference.
In the case of shielding, ground is taken to a single / common point and usually that single point continues to a specific point not
associated with other points of an electrical device. Simple said, the shielding is run to a point which provides almost no resistance to
the signal and separate from any other grounds.  If grounds are connected then signals can can travel along to what that other ground
are connected to.

BTW, you twist wire pairs as the signals running on the outside of the conductors have difficulty mixing or traveling since an inductance is
seen by the signal.  

Now it gets more interesting as one must consider how signals are received, mixed, transmitted, etc, etc.
A conductor can receive a signal via conductance or inductance. Any conductor which cuts an electrical field will acquire a  signal.
The shield will keep that signal out from combining with or riding on the inside wires.

I have used signal rather loosely. The unwanted signal is usually some kind of field  created by say a motor, vfd, etc. and that field is
made up of numerous signals of varying frequencies. Noise as it is called, because we can't understand the meaning as compared
to speech or represent it as a simple wave.

How intense a field is rather difficult to envision as you can't see it,but, for description purposes  just envision the field as a balloon
filed with signals and the source of the signals is at the center of the balloon. The noise weakens in intensity as the distance increases.

So use the above to understand how shielding is used when running wires to a motor or whatever.

FWIW,
RICH
