If I On FADAL 4020 write this program:

N1 G21
N2 G1 X-50 Y50 Z-50 F2000
N3 X50 Y-50 Z0
N4 #GOTO N2
N5 M2

I have the Error message: "ILLEGAL EXPRESSION IN LINE".

What is wrong?

[carbidecraters]

That is because you are using BASIC programming language from the late 70s on a Fadal controller. #Goto N2 is not recognized as a valid expression. Check your Fadal manual and use the L number designation for repeat subroutines.

Instructions which have been on the machine (PDF files), describing how to program in such a way...

How to do an infinite loop above using the L word?

On the computer of the machine, instructions are put equal to this:

Are you sure you typed in the letter O and not the number 0 in the machine?

Try using M99P2 in place of your GOTO call.

Are you sure you typed in the letter O and not the number 0 in the machine?

Yes, I am sure!

[hartan]

Try using M99P2 in place of your GOTO call.

I tried to do so. Such works, thanks!

How can I then use "IF" comand?

For Example:
# IF V1 > V2 THEN GOTO :N5

Controller is FADAL CNC 32MP. The controller has commands translated into German. Are maybe command by the programming in the German Language also?

[hartan]

Is it possible on my Machine working with "If" Comand?

Is that maybe impossible?

[hartan]

Whoever?

"If" word on this mashine is possible?
