Title: G-code or Coordinate probem
Hi,

I have just built a 3 axis milling machine and everything works as it should, the calibration is done against DRO so it is perfect.
Now to the problem.
I draw and prepare in F360 and use generator MACH3MILL.
When I load the file in DDCSV3.1, everything looks good.
But, if I am going to run 4 holes with a square of 50mm cc, for example, make the first hole and then move to the next hole (almost) and drill all
3 holes right next to each other.

The G-koden.

(SISTA)
G90 G94 G91.1 G40 G49 G17

This is the planed hole pattern

O------50------O

(50) O (50)

O------50------O

Any ideas?

Fristly , please delete “T70 M6” in the G-code list.

G28 G91 Z0. does the line work correctly?
I have a strange code execution.
G53 G0 Z0. - this line, executed from the flash drive, works correctly. But the same line from the program executed from the controller's memory will raise the Z-axis, the controller beeps and goes into the "Stop" mode ...
G153 G0 Z0. does not work correctly even from a USB flash drive.
Your opinion?
