G31 Probing Arrays
« on: June 27, 2013, 04:33:42 PM »
Here are the G31 Probing arrays. It includes both the interior and exterior arrays along with the control Macro AND the USER'S Manual.

HIYA BOB it is a probing routine. You go to a start point of an object then run the array. It probes the int or ext profile of the part and stores the points in a points file for use to create a cutting solution for that object.

The array always has a focal point where the machine probes to. You can tune the array by where you place the focal point at.

If you read the manual it will give you a good idea as to what it is all about.

The array RUNS as a mach3 Gcode file so there is NO macro problems to deal with.

Cool.  Thanks.  I keep looking for solutions to make probing easier.

Have you got any documentation to so explain how to use these arrays?

It is included in the Zip File as "G31 Probe Arrays .TXT"

I finally got around to trying this today.  It probes one point (in the correct direction), goes back to the start point, and then retracts Z until it hits my limit switch. 

What am I missing?

GOOD MORNING
I downloaded the G31 Probing Arrays macro from the MACH TOOL BOX section
I installed "M1299.m1s" then I launched "G31ExtPolArrayV2.01.txt" and it gives me an error
I corrected the first line M1289 with M1299
Gcode starts but when the "G1Z3110" line is reached the Z axis goes to the end of its stroke.

  (G31 External Polar Array V2.01)
   M1289
   M40
%
G90
  G0 Z # 110
  # 106 = [# 100 + # 102 * COS [# 103]]
  # 107 = [# 101 + # 102 * SIN [# 103]]
  G0 X # 106 Y # 107
  G1 Z # 123
  122 = Fix [# 122] <-------------- maybe it should be # 122 = Fix [# 122]

%

M98 P1 L # 122
G1Z3110 <-------- --------------------------------
M41
M30
%

o1 (sub1)
# 123 = [# 123 + # 121]
G1 Z # 123
  M98 P2 L # 108
  M99
 
%

o2 (sub)
  # 105 = [# 103 + # 104]
  # 106 = [# 100 + # 102 * COS [# 105]]
  # 107 = [# 101 + # 102 * SIN [# 105]]
  G90
  G0 X # 106 Y # 107
  G31 X # 100 Y # 101
  # 103 = # 105
  m99

given its usefulness it would be possible to correct it
I use version 3.043.062
I thank those who can help me
