Mach4 General Discussion / Re: Variable offset in Mach4

That sounds too good to be true! Now Mach4 is not worth considering to buy, with "Table Mapping" buying is a must. (At least for me).

Hi Craig,
I'm sorry but that exceeds my abilities.

Hi Craig,
thanks again! A lathe-autoleveller might be exactly what I want. I asked in his forum but did not receive an answer yet.

Hi Craig,
thanks a lot for that good example!

It would require some serious programming on your behalf. Are you up for it?
Well, not yet but I'll learn!

Hi John,

thanks for Your answer but in my case it is clearly the worn out bed.

Since that error is always the same I would like to write a program which compensates that error. And that program should be an appendix to the "real" program. E.g. If the "real" program says: Make a diameter 200.01 at z=100 and the appenix-program says: Go 0.1mm smaller in diameter at z=100, then the "real" programm should do an 199.91mm and the finished part will be 200.01mm.

But I don't know if that is possible with Mach4.

Hi, I am new to CNC but want to retrofit a 30 year old lathe. I would like to know if Mach4 can do the following:

I want to build a shaft with a diameter 200.01mm. The bed of the lathe ist worn out and so the shaft will be 200.10 at one end, 199.90 in the middle and 200.15 at the other end. (Just an example, no real measure).
Programm #1 says X=200.01 all the way and Programm #2 has an X- value which changes and that not even constantly. So there would be two active programs at one time with different values in X.

Is there a solution?

Cheers   Frank
