Author Topic: MACH3 V66, Gcode abnormal behavior after G31 (windows 10 64bit)  (Read 206 times)

Good morning all .
I need your help before I have 1 hair left on my head :-(
I use Mach3 version R3.043.062 on a Windows 1 64bit PC.
But I mentioned that I tested with a Windows7 64bit PC and I also tested with 5 or 6 versions of Mach3 plus base. I have the same problem :-(
Here is the problem, when I execute a G31 to position my torch on the sheet (the G31 performs well) but the movement thereafter is unstable (1-2 instructions after the G31)

Here is the code:

N0050 G20 (Units: Inches)
N0060 G90 G91.1 G40
N0110 M06 T1 F90.0  (PLASMA_0.250_65AMP)
N0120 G00 Z1.0000
N0130 X2.5084 Y1.3204
(M800)
G01 F40
G31 Z-10 F600
G92 Z-0.0623
G01 F40
N0150 G00 Z0.1500
N0170 G00
N0180 M03
N0190 G04 P0.1
N0200 G01 Z0.0600 F3.937
N0210 X2.3084 F90.0
N0220 G02 X2.3084 Y1.3204 I0.1796 J0.1796 F27.0
N0230 X2.2713 Y1.3674 I0.1796 J0.1796 F90.0
N0240 G01 X2.2947 Y1.4646
N0250 M05

the M800 is in comment because I use a Macro for my AUTO-ZERO of the Z, I put the code directly to CodeG for ease here.
But I have the same problem one way or another :(

With the code all runs well until line N0220

N0210: my cutting entry (ok)
N0220: my circle (is not executed)
N0230: overcut (OK)
and the rest OK too, it skips my line N0220 :-(

And the height ... 1 in 10 it makes the circle perfectly :-(

Then if I remove my AUTO-ZERO, This code runs perfectly.
Besides that my torch is not on the sheet :-)

N0050 G20 (Units: Inches)
N0060 G90 G91.1 G40
N0070 F1
N0080 S500
N0110 M06 T1 F90.0  (PLASMA_0.250_65AMP)
N0120 G00 Z1.0000
N0130 X2.5084 Y1.3204
(M800)
N0150 G00 Z0.1500
N0170 G00
N0180 M03
N0190 G04 P0.1
N0200 G01 Z0.0600 F3.937
N0210 X2.3084 F90.0
N0220 G02 X2.3084 Y1.3204 I0.1796 J0.1796 F27.0
N0230 X2.2713 Y1.3674 I0.1796 J0.1796
N0240 G01 X2.2947 Y1.4646
N0250 M05

Tested  and 10 of 10 is good  :-(

I would also like to clarify that I even tested on a fresh installation of Mach3 without Plugin and without configuration / customization and I have the same problem.

I really know where to go, help me :-)
