I purchased a corner probe that is triangular, and I have been working on the setting to get the probe function to work on the controller...

  
Controller  Setting Number
  
Setting
What it does
#68
3
Puts the  controller into probing mode #3
#2000
?
The diameter  of the probe tip (I put in for 1/8th inch endmill)
#2001
8.06
Tool plate  thick for X
#2002
7.77
Tool plate  thick for Y
#2003
3.6
Tool plate  thick for Z
#2004
-20
shift of X  axis before probed
#2005
50
shift of Y  axis before probed
#2006
5
Z position  before X(Y)-axis probed
#2007
5
Back distance  when the tool touches the X-axis edge
#2008
5
Back distance  when the tool touches the Y-axis edge
#2009
5
Back distance  when the tool touches the Z-axis edge
#2010
     ?
center of  tool plate
#2011
     ?
Probe  feedrate


I am not sure if the ones I have filled in are right, and I cannot figure out the ones with the question mark.


#2000 - shouldn't this depend on what size endmill I am using?
#2010 - This just makes zero sense at all to me, not sure why the center of the probe plate is important.
#2011 - it indicates that this is in relation to "G01 command in relative (G91) mode" - not sure what that means.. I think that 3mm/sec should be fast enough to start, and I can speed up or slow down from there.

Could anyone please look at the attached image of my probe (with all the measurements as well as the discussion of where I want to place it) and let me know if these settings I have are right and what I should put into the settings I do not have.

Thank you very much to anyone who responds...

Mr DWeaver
I believe i answered your question by providing this probe-center.nc file   The built in probe function is designed to work with a rectangle.
(After this file is run, the ProbeMap1.txt file will be generated in the root directory of the u disk. The coordinates of the three points and the center of the circle are recorded in the file.)

ClearCoords[1];Clear the contents of the ProbeMap1.txt file in the u disk directory

#1=0;probing the initial point X position
#2=0;probing the initial point Y position
#3=-5;probing the initial point Z position
#104=100;probed distance - was set to 100
#105=150;probed speed

G0X#1Y#2Z#3;Move to the initial point of probe

(X moves in the positive direction for the first point probed)
M101
G91G01X#104F#105
M102
G4P0
RecordCoords[1,#699,#700,#701,#702];Record the first point coordinates to the ProbeMap1.txt file
#110=#699;Save the first point X coordinate
#111=#700;Save the first point Y coordinate

G90G0X#1Y#2;Back to the initial point

(Y moves in the positive direction for the second point probed)
M101
G91G01Y#104F#105
M102
G04P0
RecordCoords[1,#699,#700,#701,#702];Record the second point coordinates to the ProbeMap1.txt file
#112=#699;Save the second point X coordinate
#113=#700;Save the second point Y coordinate

G90G0X#1Y#2;Back to the initial point

(X moves in the negative direction for the third point probed)
M101
G91G01X-#104F#105
M102
G04P0
RecordCoords[1,#699,#700,#701,#702];Record the third point coordinates to the ProbeMap1.txt file
#114=#699;Save the  third point X coordinate
#115=#700;Save the  third point Y coordinate

GetCenterPos[#110,#111,#112,#113,#114,#115,116,117];Calculate the center coordinates and store them in #16, #17 variables
RecordCoords[1,#116,#117,#701,#702];Record the center coordinates to the ProbeMap1.txt file

G90G0X#116Y#117;Move to the center of the circle

G92X0Y0;XY coordinate clear
