Field names are as they appear in each form.

Common fields#

Field	Meaning
Tool	Only tool types that suit the operation are listed. Browse library… finds others
Start	Where in Z the cut begins: Auto (from earlier cuts), Stock top, Floor of operation, Custom…
Depth	How far below the start to cut
Step Down	Depth per pass. Auto-set from tool, material and rigidity when Auto Feeds is on
Direction	climb or conventional
Stock Allowance	Material left on the wall. Negative cuts past the line
Ramp In	Enters on a slope (2× tool diameter, 50 % feed) instead of plunging

Operation	Does	Needs	Tools offered	Has Start
Profile	Cuts along a line	Any path (open = centerline only)	End mill, bull nose, ball nose, V-bit, taper	✓
Trochoidal	Cuts a slot in loops	Any path (open = centerline only)	End mill, bull nose, ball nose	—
Pocket	Clears an area	Closed path	End mill, bull nose, ball nose	✓
Drill	Makes holes	Circles or clicked points	Peck: any tool · Helical: end mill	✓
Surface	Flattens the stock	Nothing selected	End mill	—
V-Carve	Carves with depth from width	Closed path	V-bit, taper	✓
Photo V-Carve	Carves a photo as grooves	An image	V-bit	✓
Inlay	Cuts socket and plug	Closed path	Roughing: end mill · Finishing: V-bit, taper, end mill	—
3D Profile	Carves a 3D surface	An STL or image	Finishing: ball nose, bull nose, taper · Roughing: ball nose, bull nose, end mill	—

Field	Options / meaning
Tool	End mill, bull nose, ball nose, V-bit, taper
Cut Side	inside (hole edge) · outside (part edge) · centerline (on the line)
Start, Depth, Step Down	See common fields
Direction	climb · conventional
Optimize Path	One routed cut for a whole sheet of parts. Shown when several parts can share it
Bridge Gaps Through Waste	Under Optimize Path. May cut straight across waste between parts, up to a set length, to join toolpaths
Stock Allowance	−5 to +5 mm. Hidden for centerline
Round Inside Corners	Rounds the path in inside corners so the machine keeps its feed. Hidden for centerline
Ramp In	2× dia, 50 % feed

Field	Meaning
Tool	End mill, bull nose, ball nose
Cut Side	inside · outside · centerline
Depth, Step Down	See common fields
Direction	climb · conventional
Loop Amplitude	How far the loops swing each side
Step / Loop	How far each loop moves forward
Ramp In	Spiral down over 2× dia, 50 % feed
Finishing pass	Clean sweep after the loops (the two walls, on centerline)

Slot width (centerline) = 2 × Loop Amplitude + tool diameter.

Field	Options / meaning
Invert Pocket	Shown for nested shapes. Swaps which area is cleared
Tool	End mill, bull nose, ball nose
Strategy	auto · raster · contour · morph · adaptive
Start, Depth, Step Down	See common fields
Stepover	% of tool diameter. Called Engagement on adaptive
Angle	Raster direction. On auto: tick Auto (longest passes per area) to let it choose
Direction	climb · conventional
Stock Allowance	Left on walls; negative grows the pocket
Ramp In	2× dia, 50 % feed

A rest-clearing pass always runs before the wall pass. Alt-click Generate to force a strategy that declined the shape.

Field	Meaning
Mode	Peck at Points · Helical (Circle)
Drill Points	Peck: centres of the selected circles, or click the canvas to place points
Source Circles	Helical: the selected circular paths, each bored at its own diameter
Tool	Peck: any tool (a drill is best) · Helical: end mill only
Start, Depth, Step Down	See common fields

Pick order = drill order. Peck with an end mill, ball nose or taper shows a warning.

Covers the whole stock. No selection needed.

Field	Meaning
Tool	V-bit, taper
Start	See common fields
Max Depth	Deepest allowed. A limit, not a target. The line under it gives the widest cut

Field	Meaning
Image	An imported PNG, JPEG or WebP
Tool	V-bit only
Start	See common fields
Angle	Groove direction, 0–180°
Depth at White	Depth for the lightest areas
Depth at Black	Depth for the darkest areas
Line Spacing	Read-only. Equals the deepest groove's width; shows the line count

Field	Meaning
Roughing Tool (End Mill)	Clears the bulk
Finishing Tool	V-bit or taper (sloped walls), end mill (flat walls), or None — roughing only. Same on both halves
Inlay Depth	Socket depth
Step Down	Roughing depth per pass
Stepover	10–90 %
Glue Gap	Space left under the plug
Clearance	Slack around the plug, −1 to +1 mm
Generate	Female (socket) or Male (plug)
Invert	Shown for nested designs. Which part is the plug
Ramp In	2× dia, 50 % feed
Mirror	Male only. Flips the plug for text or non-symmetrical designs

The button reads Generate Female Toolpath or Generate Male Toolpath.

Field	Meaning
Model	Listed under STL or Depth map image
Relief Depth	Depth map only. Height from background to white
Dark is high	Depth map only. Black becomes the top
Boundary	Model box · Stock · any closed path
Model Top Below Stock	Lowers the whole model

Roughing (shown once a roughing tool is picked)

Field	Meaning
Roughing Tool (optional)	Ball nose, bull nose, end mill, or — None (single-pass) —
Roughing Stepover	5–100 %
Roughing Step Down	Depth per level
Roughing Angle	Blank = auto (finishing angle + 90°)
Stock Allowance	Left for finishing, 0–2 mm. Default 0.3 mm

Finishing (labelled without "Finishing" when there's no roughing tool)

Field	Meaning
Finishing Tool	Ball nose, bull nose, taper
Finishing Stepover (XY)	% of diameter (of the tip on a taper)
Finishing Strategy	Raster · Waterline (depth maps: Raster only)
Angle	Raster only. −90° to +90°
Max Depth	Deepest below stock top
