Does Mach 3 support #variable use in programming. The simulation toolpath in Mach doesn't seem to like it.
Here is an example below.

Thanks

YaNVR got you set up(;-)

With Mach3 you cannot use the - directional sign with a #var. You have to solve inside the brackets to make the #var negative.

AND Yes I know that ain't right BUT that is just the way it works in MAch3 .

Thanks guys I'll give it a try. I was used to fanuc style programming. But that tip shed some light on the subject.

Hi,

what about if statement in mach3, is it possible to use it? what will be the format of it?
sting

There is NO conditional in Mach3 gcode.

(;-) TP

A few tips-

Regarding assigning parameters to negated values-

#1 = -#2 (Doesn't work)

#1 = [-#2] (Doesn't work)

#1 = [#2/-1] (Works)

Although there are no conditionals, to get conditional processing I often use L param in subroutine calls to conditionally execute code based on a variable being zero or non-zero. Its a hack but it works, see below.

This runs the subroutine one time if #106 is non-zero, doesn't run if #106 is zero.

M98 P1351 L[ROUND[[#106 + 0.00001]/[#106 + 0.00003]]]

Also:

#1 = [0 - #2]
#1 = [#2 * -1]

Ray L.

Redirection from Gcode

M1000 R29    (R sets the Goto #)

o29 (o word somewhere in your code you need to GOTO)

M1000 Code        
Code"M98 P" & Param1()

A little strange but it does work

Just a thought, (;-)TP

The M1000 code should read

Code"M98 P" & Param3()       'to use the R param
