First I want to thank everyone who helped me get this far but apparently I am missing something. I am trying to engrave on the O.D. of a piece of 2." round stock on my Lathe.

Have a look at the macro prg. below and that part prg. and tell me if you guys see whats wrong.

It gives me a "009 ILLEGAL ADDRESS INPUT" ALARM.

I am trying to take the Y values in my prg and convert them to C-Axis moves in degress with the macro.

I don't think you can use the letters that use as machine command address like G O Z Y X H few others.

Have you tried it this way?

Missed read program to start so skip me first post..


Question- Are wanting the Z and Y to feed at same time as C?
If so The Z and Y move needs to be on same line as C.

G01C[#25*.0174]Z.0002Y.0117

My lathe only has Z, X and C with a sub spindle B.

I am wanting to take the Y axis moves in the prg and feed C axis in degress in its place.

thanks Jon

The Y address may not be permitted on a lathe. For the purpose of calling a macro, you can use any other address that permits decimal points, like "A".

Also, CBNDude is right. If you want the Z axis to move also, you've got to make it move in the macro. The G66 macro call will just pass the numbers to the macro, and it won't move the axes at all. Try this to call the macro:

G66P9100Z.0002A.0117

Then, inside macro 9100, move both the Z and the C axes with a single G01 command, like so:

G01C[#1*.0174]Z#26

There should be a chart in the front of your operator's manual that will tell you the legal addresses, and it will also tell you which addresses can use decimal point formatted numbers and which ones are simple integers. For example, an address X, Y, Z, U, V, U, or A, B, or C should accept decimals. The addresses M, T, S, etc. are integers. Your lathe may not permit the addresses Y, B, or V because this axis doesn't exist on your machine.

Just a guess ...

ok that makes sense now.

I will report back after christmas.

thanks again

I dont think it is possible to do this on a fanuc 18IT.. Mabe it is possible to scale one axis (c-axis) (mabe scale it in the text producing prg).and change the Y to C in a simple text editor..
