Yes, and in an early version, R14 or 2000

export your files as DXF acad R14 or 2000 format.

It could be that Mach3 is set for absolute arcs and MaxNC is incremental, you can change Mach3 in the config screen for abs or inc arcs.

It should look more like this :-

%
N10 G0 Z2
N20 M3 S2000 F200
N30 G1 X0 Y0
N40 Z0
N50 M98 P10
N70 X-20
N80 M98 P10
M30

O10
G91 Z-0.5 F70
G90 Y-30 F150
G91 Z-0.5 F70
G90 Y0 F150
M99
%

General Mach Discussion / Re: Re-useable lists of Parameters for use in G-Code files

You can do what you are doing you just need to use the correct sets of variables:-

1 to 33 are local variables, there value can only be used within the current g-code file,

100 to 149 and 500 to 531 are global and can be used over any number of files.

In the later versions of Mach variables 500 to 600 are global variables.

Mach version 4 is much more strict about # values and locks certain blocks to read only.

G52, G92 and all the G54-G59 fixture offsets position data is stored in #2500 range

Tool offset data is stored in the #2000 range.

Set your G54 XY & Z to a known value then read #2501, 2 & 3 see what you get.

If you are using the demo version it has a line limit, the full version has not.

Just a word of warning :-

#2001 onward are used by Mach3 as data locations for tool offsets, you may get strange results if you use them.  #100 to #149 and #500 to #531 are user variables #1000 and over are system read only use. That said you can write to them to set system values.

A G02 or G03 when using R can only be commanded with less or equal to a 180 degree move, in some instances the rounding error from the previous and next moves can make this 180.0000001 so the error happens, the new versions have this fixed.

Do you have a G43 in your g-code file?
