command: clearance value
purpose: adds additional clearance prior to starting an operation
description:

For various operations and in order to eliminate unnecessary move commands, prior to and after finishing an operation, the tool will raise clearance distance. As this new variable is implemented, commands that use it will be referenced below.

description:
For encoder based systems, defines the number of encoder steps to decelerate from velocity vel down to velocity minvel. For stepper motor systems, defines the number of pulses to decelerate from velocity vel downto velocity vel.

command: Drill x,y,z,z2 d1[,plunge],[xoffset,xcount,yoffset,ycount]
purpose: Used to drill holes at a given coordinate with an optional plunge to prevent binding of the drill.
description:
For a regular hole, this command moves to location x,y,z1,z2 and drills to depth d1 in plunge increments if specified. If xoffset,xcount,yoffset,ycount are defined, this command drills an array of holes starting at x,y,z1,z2 and drills an array of holes in one neat little command.


drill 1,1,1,0,1.5 ; Drill a hole to a single location
drill 1,1,1,0,1.5,0.5 1.0,5,1.0,5 ; Drill 25 holes evenly spaced 1"x1" 1.5" deep in 0.5" increments
drill 1,1,1,0,1.5,0.5 1.0,5 ; Drill 5 holes evenly spaced 1" by X 1.5" deep in 0.5" increments
drill 1,1,1,0,1.5,0.5 0,1,1.0,5 ; Drill 5 holes evenly spaced 1" apart 1.5" deep in 0.5" increments

command: edge axis+/-
purpose: To determine the edge of a part with a digital edge finder
description: Axis can be x,y,z,a,c in a positive or negative direction. For c, the edge finder is used to find the center of a hole, and offsets are irrelevent.


This video issues the following commands:
move 2,1,1,0
edge z-
move 2,1,0.1,0
move 2,3,0.1,0
move 2,3,-0.1,0
edge y-
move 2,0.2,-0.1,0
move 2,0.2,0.1,0
move 2,-0.2,0.1,0
move 0,-0.2,0.1,0
move 0,-0.2,-0.1,0
edge x+
move -0.2,-0.2,-0.1,0
move -0.2,-0.2,0.1,0
move 0,0,0.1,0
prompt the tool should be above the far right corner
Examples: edge z-
This command touches down on the part. edge c+
From the current position, the tool looks for the 4 edges and sets offsets to the centerpoint. Recommended is to perform this command twice in succession for accuracy, unless the hole is damaged. Direction +- is ignored but required. edge x+
Moves right until an edge is found.
A calibration table is required to assure that the edge finder matches tools. The reason for this is that the proximity sensor seems to have different detection for different diameters. For z and a, recommended is to use the following offsets as calibrated using calibrate.cnc, a digital depth gauge and a hole located in the prep section of the file. For some edge finders, center post grinding is required to true up the edge finder. In this case, put in ot.ini the following:

command: Facep1p2 x,y,z,z2 z,y,z,z2 d1,d2 [dinc]
purpose: To face from point1 to point 2 at a given depth in dinc increments.
description:
This is usually used as a followup to the face command to clean up edges, but can be used for many other functions. For example, milling to a given depth with a ball nose endmill could produce a channel. Unlike the face command, facep1p2 does not have to be rigidly defined by X or Y. However, the z coordinates should be equal unless a ball nose endmill is used simply because of the chatter that would occur, but this too is not required.

command: home
purpose: home to limit switches
description:
Seeks first to Z home switches, and then to X and y concurrently. While it's possible to home all 4 axis at once, this is unsafe on some occasions.

command: rdrill x,y,z1,z2 radius,sangle,astep,count depth,[plunge]
purpose: To drill holes along an arc description: This command is used to drill holes around a radius point in given increments of degrees (astep), starting at sangle and continuing until count holes are drilled. If Plunge is not defined, plunge depth is equal to depth.

command: rbore x,y,z,z2 bradius,startangle, amgle, count, d1,d2 r1,r2
purpose: to bore a series of holes radially
description: Starting at x,y,z,z2, A radius of boring holes is defined. Starting at startangle, and proceeding for count locations, hole is bored to a given depth and radius.

See also: xystep dinc rstep bore
command: rface x,y,z,z2 startangle, angle, count, r1,r2 d1[,d2,a2]
purpose: to face a series of slots radially
description: Starting at x,y,z,z2, A radius of boring grooves is defined. Starting at startangle, and proceeding for count locations, a slot is faced to a given depth from the inner radius point (r1) to an outer radius point (r2). If a2 is specified, this facing operation is rotated about r2. Unlike most radial operations, r2 can be less than r1 and are merely used to define starting points in the facing operations.

See also: xystep dinc rstep bore bore
command: rstep value
purpose: to control the resolution of radial movements
description: defines positional stepover for radial motion.


Example: rstep 0.005
Each increment in a radial operation calculates its move as a step of 0.005" increments. Usually, this value is closer to 0.001 or lower for a proper finish. This value should be greater than the value in any direction a step takes, or an encoder takes for Servo based systems.

command: tool # [radius depthcomp]
purpose: Defines a tool offset and radius for a given tool, or optionally sets the tool to be used for offsets
description:

For each tool definition, a radius and depth offset is assigned.
Example for a 1/2" endmill
;Tool 0 0.1 0.00 This is the hard coded definition of the edge finder but can be overridden with tool 0 radius 0.00
Tool 1 0.25 -0.005
tool 1 ; Assign offsets using tool 1 definition
edge x+ 0.1 ;assigns tool 0 and finds edge.

Special note: This command is very dynamic, as home, proxy, and edge commands automatically revert to tool 0. Whenever you home, proxy or change tools, you need to assign a tool so that the machine can adjust for it. See also: edge bore facep1p2 face drill
command: tc
purpose: Moves to the system tool change position
description:

As with the homing sequence, tool change involves first moving from the current location to tool change Z. Afterwards, x and y are moved to tool change. Because this position is used for milling orthotics, this position is in millimeters.

command: tool # [radius depthcomp]

command:vel value
purpose: Sets the velocity in inches per minute (IPM)
description:
For a given program, the vel command can be issued to determine velocity. Also, in the terminal, pgup and pgdn keys can be used to increase and decrease velocity. The stepper motor controls should never exceed 22 IPM and should be lower for higher torque operations, whereas the servo based system should never exceed 150 IPM.
