hello!

When using my cnc lathe, that has a rear tool post with tool changer, I can't seem to get the gcode right for cutting.

Everytime I use the lathe wizard, it thinks the tool is in the front and posts that way, how do I change it to use the rear post?

I already tried to change the tool from front to rear im mach 3, still doesnt help, it still assumes that the tool is in the front.

Any help?

HIYA Mike I have not forgot you dude I am trying to find someone that is more familar with turn to help you out. I am way too rusty on it to be of much help. UNLESS no one steps up THEN I will drag out the books and give it a whirl.

Hang in there, (;-) TP

I emailed ya it was the front and rear tool post selection, all must be front or rear

mike^3,

My lathe uses a front tool post and in the tool table they are all designated as front based on a master tool
touch off.
My experience is limited with using a rear tool post, but Hood has specific knowledge.

So,

As you said, "Do Not" mix  front and rear tool post in the tool table.

A good example is when trying to use a gang tooling setup as that could easily lead one to create tool offsets  as front and rear.
Someone posted a write-up called  "Lathe Gang Tooling G52 Offsets". Just thought I would make note of this for other readers
of the thread. Mixing front and rear designations is a recipe for problems.

Note that the X axis + direction is reversed for a rear tool post and if you check "reversed arc's in front tool post"
the motion of G02 and G03 is reversed.

Thanks rich, I'm trying to get the threading to work now lol,

Have a read of "Threading  on the Lathe" write up which you can find in Member's doc's.
Lot's of good info you should know before you go!

Hows Mach 4 lathe coming along?

Don't know as I have not been following the development of Mach4 for some time now.

Any help?

I do it like this - open the program with texteditor and  in menu edit and
then  replace  X to X- replace. That's it!
