I am trying to learn LT and Mach Turn, I've been using the wizards in Mach Turn but would like to be able to post and load gcode of some more complicated profiles.

See the screen cap.

Sorry if this is covered somewhere, I have been reading posts for two days now and can't find anything on it.

Thank you,

Gerry

Hi Ron,

I've been using Mach3 Mill for years and just downloaded NFS Turn Wizard .08. Watched the tutor video and getting familiar with the program. I don't seem to get Gcode generated for peck-pause or peck-retract Drill. It will only generate for Continous. What am I missing? Attached is sample file.

thanks for input,

Bert

I was seeing this too, thought it was just my inexperience.

Thanks Ron,

Gerry

Thanks fellas,

Do I need to do it in Mach3 Mill, settings page and somehow copy it over to Turn?

Right now some tools are not clearing the stock for a tool change. It seems to just go to the last position of the last cut?

Thanks,

Gerry

Thanks for putting up with me Ron, much appreciated.

I set the DRO's by touching to a pc. of paper in X, I measure the part and add twice the thickness of the paper and enter that number into the X axis DRO. In Z I face the part and enter 0 in the Z axis DRO. I was doing a light cut in X and measuring the result and entering that in the DRO, but I stopped using that method because I am doing this over and over to learn and was using up material.

I use the same method in both the NFS wizard and the standard turn wizard, The standard wizard works and NFS one doesn't I think I must be doing something wrong in the NFS wizard.

I'll play with it more and see where I'm messing up.

Thanks,

Gerry

Because you set Safe Z to 1.5 on the tool select screen. Its on the lower right side of the tool select screen.

Thanks again Ron for your input and quick replies.

Yes, it is set to +1.5 but isn't that where the lathe travels for a tool change? That part works fine, it is when I hit cycle start after tool change that it goes deep into my part in either X or Z and hits a limit switch.

I'm going to try and make a movie of what I'm doing and the results tomorrow. I'll post it on YouTube. Hopefully that can shed some light on what I'm doing wrong. I know it is just something simple that I am missing.

Thanks again,

Gerry

thanks for the quick reply Ron.

Why do you think in the NFS wizard the Z start is ~1.5 inches to the negative with Z start set at 0 and in the other wizard the Z starts at 0 with the Z start set to 0?

Can you see that in the tool path window? Every time I go to run the program it retreats in Z- and hits the limit switch. Well into my part, not at the face?

Thanks,

Gerry

Just maybe to help clarify my previous post...

I am entering Z start at 0 and X start at the outer dia. of my part (in this case +1.131) and Z end at -1 and X end at +.881 (removing .25" material) in both wizards

You can see in the tool path windows how each wizard shows different starting points too

Standard wizard

And the NFSTurn wizard

Thanks,

Gerry

A couple of questions.

I downloaded and installed the file (NFSturn008.zip) at the beginning of this thread but when I open the NFS turn wizard it shows it as being "licensed NFS Turn V 0.6".

Do I have v 08 or 06?

Also I have been trying to understand the various wizards and doing so I keep having a problem with the NFS wizard doing unexpected things and the standard turn wizard doing what I expect when doing the same type of operation. For example, I can do a turning op in the standard wizard with no problem but when trying to do the same type of op in NFSTurn the lathe keeps hitting either the plus X limit switch or the -Z limit switch on initial move. I believe I am entering the same perimeters in the boxes but to be honest I could be a little confused on what I'm supposed to put in them... X End, X start, etc. I seem to be doing it right in the standard wizard but must be getting it wrong in NFSturn.

Is there any documentation or manual for NFSTurn? I found Ron's video on intro to NFSTurn but I am wondering if there is something out there that steps you through each operation and what each data box is for.

Sorry, I am very new at lathe work and maybe if I was more experienced the screens and how and what each entry means would be more self explanatory.

Thanks,

Gerry
