CNC12 Probing System Sub Program Information rev2 DRAFT.. 1-10-20

This document describes how the stock Centroid probing and digitizing routines that are built into CNC12 function at the macro level.
If you intend to use the Centroid built in probing routines as is (see Mill Operators manual Chapter 8). There is no need to read any further. This information is provided for OEM’s, Intergrators and Power Users that have a special Probing application that requires either an all new Probing Macro or to edit one of the macros currently in use by CNC12

Centroid’s CNC12, CNC11 and CNC10 CNC software use sub-programs to preform the Part Probing cycles. To keep things short we will use “CNC12” in this document to refer to all three version of Centroid CNC software.

CNC12 software sets some variables before “probe_cycles_select.cnc” is called depending on the probing cycles that are selected in CNC12.


If a sub-program is calling a lower sub-program it may be passing variables to the lower sub-program. A lower sub-program may not be able to be used by itself unless the program that is calling that lower sub-program sets the variables that are needed for that lower sub-program and any addition lower sub-programs that are called within. In the header of each of the sub programs there a line ; Usage: that shows what variables are being passed to that sub-program. There may be more than one Usage line in the header depending on which higher sub-program is calling that sub-program and the variables that need to be passed down. Some of the sub-program calls below show the variables that are being passed to that sub-program cycle. Depending on If statements not all of lower sub-programs may be called in that sub-program or different values are sent down for the variables.

Main Programs

1) probe_cycles_select.cnc
2) probe_get_constants.cnc
3) probe_get_modals.cnc

Text files with program and variable information.

1) “probe_user_vars Rev 2.txt” * listing of some of the variables that are used in each sub-program.
2) “System_Probe_information_of_sub-programs.odt” * Listing of sub-programs and the order that they are being called from the “probe_cycle_select.cnc” and variables in numerical order with description of what they are being set to. Some variables are being reset to different values based on the state of other variables.

; Filename: probe_boss
; Purpose: Find the center of a boss
; Programmer: John Popovich
; Date: Nov 9, 2010
; Updated: May 10, 2011
; Usage: G65 "probe_boss.cnc" X[clearance_distance] Z[clearance_height] E[initial_axis_index] D[initial_direction] F[traverse_speed] B[plunge_speed]

; Where: clearance distance = the x and y clearing distance
; clearance height = the z clearance height
; axis_index = 1 through max axis, the axis to move first
; initial_direction = the direction to move first
; traverse_speed = feedrate during the boss traversing moves (moving up and over to the other side of the boss)
; plunge_speed = feedrate for the plunge move (after traversing across to the other side) it moves down before probing. You might want this slower if you are unsure of the boss width.
; Notes: the probe will be at the center point at the end of the macro
; the plunge and traverse speed are normally the fast probing rate. However, some CNC11 setup routines for five axis systems want to move faster to save time. This is ok since the routines have a really good idea of the location and size of the boss they are probing.
