Mike,

The clearance is how far away from the stock you want to pull out to when doing your rapids.

Thanks for reply, doing test turns, I have found you have to minus the clearance value from the X end value, as tool goes to +X clearance at start of cut run, is that your experiance? or am I not running programme as intended.
It would be helpfull if we had a video tutorial for turn wizards! maybe the guys are working on one.

That is sort of correct. 
The clearance is for tool clearance,  so if you set in 1" for x start and .5 for x finish, and lets say 0 for z start and -1" for z end.  say .005 for rough cut and .01 for clearance, and finish cut of .002
The first move will go to z start +.01 and x start +.01, this will be a rapid move. 
Then it will move in to x - rough cut, or .995
then it will move z to z end - finish cut or - .998
then it will move x to x start - rough cut and z to z end + clearance rapid move.

all the clearance is for is to ensure the tooltip is well clear of the work when doing the rapids back to the start point of your next cut, it will clear the workpiece in both the x & z.
The clearance will not affect the final end cuts or final dimensions,  the finish cut will cut it to what ever you put into your z end and x end.

If you go to the downloads section you will find some more turn wizards that I made to do other cuts not found in the standard turn wizards.

I wouldn't hold my breath for the tutorials,  they are busy making new program functions.

Another way to really understand how the wizards work is if you have a little basic programming experience or knowledge and some gcode understanding, use the screen designer to open up the wizards and dig down into the basic code that is used to generate the Gcode from your inputs.  It can be a great learning tool on how these work.

Ok got it, I had made a mistake on x end number which ironicly was the same as clearance value, hench much confusion.

As I have an awefull memory I will write a set of instuctions, and will post for others, would you check them?

Thanks for your help

Mike,

I would be glad to check them. 

Check out the additional wizards I made in the downloads section.  They are an ID groove, an end groove, some tapers if you need to taper up to a face or don't know the angle just start and end points, and an experimental parabola.

Mike,

It is in the chat forums, go towards the bottom of the topics, there is a downloads section, then drill down to the others section and it is in a topic extra turn wizards.

Downloaded extra wizards followed were to put them, but now have lost Turn screen. Done Veiw/Load screens/turn addons, but no joy

I think the only thing wrong is you don't go to view, you go to wizards and they should show up there.

you need to put them in a new folder under mach3\turnaddons\my turn

put the turning.set and turning.set.def here

Then make a subfolder in the folder my turn, called bitmaps, this is where the bitmaps are put.

Then when you run mach3 don't use view, just go to wizards and it will show up in the list there.

Yes I have put the files in the places you recommend, but I have lost the Turn screen If I go to Veiw/load screens I can get mill screen, but can't find turn screen.

Thanks

Mike,

When you go to load screens, select the file types as turn sets   they have the file extension of lathe.lset or 1024.lset

Are you seeing the wizard from the wizard menu selection?

Hi, Mike

A picture is worth how much ?

Hope this Helps, Chip

Arnie & Chip

All sorted, I seem to have a different version, as the lathe file is an red flash with yellow M3 icon marked 1024 and no extension, which is very confusing as mill & plasma have usual icons !

However the extra wizards are now in the menu,am sure will be usefull

Thanks for help

Mike
