OK, so I'm sure it's been covered but I can't find it.

I'm using the threading wizard in Mach 3.042 and when I go to run it, it move the carriage past the physical limts in the X6" and Z6" range. I have no idea why it's doing that and it crashes my carriage. The G code doesn't mention these coordinates so it must be some code. Please help. It does it for the first move.

Here's the code, oh I don't have any offsets set whatso ever I just zero the tool to the right coordinates. And I'm working in Inches. Oh and another thing the only werid setting I have is the IJ mode is set to absolute instead of incremental for my Dolphin CAM. Thanks.

The second line is moving the X and Z axis to 0.1 in machine coordinates, do you home the machine?

No, I don't home it...OH, how can I get rid of that, I don't have limit switches on my machine?

I am afraid I dont use the standard lathe screen so not sure if there is a RefAll button on it or a means to set machine coords to zero, if there is then pressing that at an appropriate place would set it as machine zero.
Or if you edited that line out of the code it wouldnt go there, you could also edit the VB in the wizard so that it doesnt add that move, I think I did that in mine.

Just had a look at the VB, if you put the Tool number as zero then it shouldnt add that toolchange move, if you have the tooltable set however that wont be any good.

I have the same issue when generating files for my little 9x20, its just moving to a safe place to do a tool change if memory serves.  you just need to open the file in the editor and delete the g53 line  then save the file.

Thanks. I got it working, now the problem is understanding threading...so frustrating.

youll get the hang of it , like most canned cycles once you figure out what each of the variables are you'll just starting writing the code manualy. now if we could just get a couple of other common canned lathe cycles active ;)

Well the problem I'm having is the difference between using a full profile ER16 Insert or a partial profile ER16 insert. I'm doing a custom thread that's 1.77 OD for the bolt and 32 TPI, so I'm using 32 TPI specs. The problem is the bolt thread depth is .0192", but what's confusing is I asssume that's for a full profile cut. If I'm using a partial profile I'm supposed to leave a small flat on top, but that doesn't tell me how deep I should go.
