This is what I get from your code in Mach3 and also what AlphaCAM makes of it :-

On the offsets page click 'Save work offsets', then click 'Save' in the window that pops up.

If that dose not work, go to Config menu, select Fixtures..., click save.

What have you got set in mach's motor tuning, your counts per should be 2048 for each rev of the motor, if this is set way too low the motor will be hunting all the time.

Have you a picture showing the problem?

Why not do a G28.1 and let mach do a normal find home position.

You can have a 'home off position' set for the C axis which will then allow you to do a rapid move to the required starting position.

That's how I do mine.

Or am I way off what you are trying to do.

General Mach Discussion / Re: Has anyone retrofitted a 4 axis lathe?

« on: November 19, 2009, 12:08:10 PM »

The main problem you will have with a 4 axis lathe is that mach blends all axis motion together, you need to be able to run each turret separate, this is not possible at the moment so one turret can not be in rapid and one cutting so you loose the benefit of the 2 turrets.

Now I have read your whole topic I think I get what you want.

What you need to do is create a macro like this :-

Enter the following lines into notepad and save them as M1800.m1s in the macro folder inside the profile folder you are using e.g. C:\Mach3\Macros\Mach3Mill making sure the last line has a return on the end.

SetVar(100,GetoemDRO(83))
SetVar(101,GetoemDRO(84))
SetVar(102,GetoemDRO(85))

Now in your g-code program when ever you want the current position of the machine relative to the home position command M1800

Then #100 will be equal to the x position #101= to y and #102 = to z

So your program would look like this

G00 X0 Y0 Z10.
M1800
(Do calculations here)
#100=[#100/2]
#101=[#101/2]
#102=[#102/2]
G00 X#100 Y#101 Z#102
M1800
Etc.
