are you still talking about this g-code ?:

Code: [Select]

N100G00G21G17G90G40G49G80
N110G71G91.1
N120T1M06
N130 (End Mill {3 mm})

N270G00Z15.000
N280G00X0.000Y0.000
N290M09
N300M30
%

here
N200 G00 X-23.500 Y-23.500 Z10.000
the g-code tells machine goto X-23.500
so if your left bouandary is X0 then it whants to go outside.


as sayed before, to run this code jog your machine somewhere to the Center of bed and lower Z-axis aprox 15mm

then press X-Zero and Y-Zero and z-Zero and THEN run the code

for your z-axis up is positve and down is negative?

goto to Zero means goto Zero whereever you set the Zero of your z-axis
if the actual Position is negativ it will go up if it is positve it will go down.

... and still is problem with position of my G-code like on picture...
I didnt have had such problem before I changing minebord and instaling new Mach 3

jog your machine somewhere in the middle press Zero X , Zero Y and Regen Toolpath


according to your screenshot X-Dro = 126.something and Y-Dro is 52.something
Center of your code is X0/Y0 and coordinates are from -23 to +23 so the toolpath view
is axactly showing the reality.

I know about such option, but if you change DirLA X and Y you changing direction for HOME and XYZ going in oposite.
of course XY  buttons of MPG MODE  working correct now.

Config -> Homing Softlimits -> Home Neg.

Config -> Ports&Pins -> Motor Ouputs -Change DirLowActive should also invert direction without swapping wires

your g-code is so that X0/Y0 is in Center of part.

on a normal Installation
x-movement (millbit related to part) moving from left to right is positive
y-movement (millbit related to part) moving from front to back is positive
 
related to your g-code workpiece X0/Y0 must be somewhere in the Center of table not at the border.
