 Idealy the lead screw should have screw support at both ends. The other option would be to make a bracket which would
provide a quide at the un anchored end to keep the screw from whipping around. There are a number of combinations of
 how to support the screw. You will find sound information on the subject in many of the ball screw manufactures info
such as Nook, NSK, etc. Have a look at what they recomend as far a distance between supports as compared to screw
diameter.
The brass nuts on the screws wear rather quickly if you run the axes at high speed. By wear i am meaning backlash.
 So the anti backlash nut adjustment setting won't last very long. You can improve that somewhat by making a longer nut or two instead of one.
Note that you require an odd ball tap / not cheap ( don't ya love they way they  design things in like that).

Phil,
I have never used Autosketch. It is vector based and exports to a dxf so assume it should work.
I don't know why dimensions are incorrect. LT provides for setting diameter, radius, or metric on import.
Make sure that your drawing units are set correctly in Autosketch. I am quessing that it's either
the way you are drawing it or some export setting in Autosketch but realy don't have a specific answer for you.
Post the DWG  and DXF file. I believe there are other folks in here that use it and may chime in.

Can you be more specific as i am not sure what you mean.

Are you using steppers or servo's?

Simpson,
I was assuming the R8 or 5 spindles would be used in your 4th axis you have been working on.
So comment referred to end use.

Simpson,
Just a thought, but look into what the RC helecopter guys do. Balance is lost once you put something into the spindle.
Make note that the active system must be looked at, not just a single item, so even tool chatter can create a condition for resonance.

FWIW....RICH

What the heck are you talking about?

Maybe they changed their tune..........the rub is:
There was a number of users near me, some went back to the DOS days of DeskCNC. About two years ago or so ,we were informed that in order to use their forum, ask or reply to questions, it would be necessary to pay a $60 a year fee. Insulting, uncalled for and a real turn off.
Frankly,it was a good thing, as we all use MACH which is a much better product than DeskCnc.
I wish them well and may the bird of paradise bestow on them what is deserving. 
End of this subject matter as it is off thread.

There's a few and alll a little different:
Circular Pocket Wizard
NewFangled Solutions
LazyCam - does not do a continuos spiral / steps off by an offset amount once the Z is plunged
Andys Circle Routines - i think it spirals around but may  not plunge  and spiral at the same time, don't remember ( nice wizard interface )

Lazy Cam trashes my Z(-) settings when you import from Mach 3.

Normal route is to import a proper dxf file and use LC to generate the code, not try bringing some code from Mach3 into LC.

There seems to be no easy way to specify the Z depth for pocketing.

It's rather simple, have a look at the manual.

Is this the normal results most/many/some users get from LazyCam?

 
Nope, done some nice things with i,  there are times it can get buggy, and the manual gives a list of known bugs.
Best to post the problem / file / question and someone will respond.

or use DeskCNC for most things

If that works for you, then great, but in the reverse, i haven't used DeskCNC in a while because the combination of the Mach  mill and turn wizards, LazyCam, LazyTurn, satisfy\ies a lot of what needs to get done until you get into 3d. Best of all the user dosen't need to  to pay a $60.00 a year fee just to be able to post / ask  a question. I find that insulting, uncalled for, and a real turn off to using anythhing from that site.

General Mach Discussion / Re: Mach3 turn wizard. How to link wizards?

« on: May 11, 2010, 08:09:19 PM »

You could set home at a spot away from the piece and thus have a work offset. Then you could run each wizard without pasting them together.
Have a look at Appendix "F" in the LazyTurn Manual.

I found the same problem and I don't know why some work and some will not. Never seen anything posted for an answer on it.
