Onefinity Cutting Area — Nest Your Parts on the Real Bed Size
The Onefinity Woodworker cuts about 32" × 32", the Journeyman about 48" × 32", and the Elite Foreman about 48" × 48". This calculator nests your parts against your bed size so you know how many come out of one spoilboard load before you cut. Free to try, in your browser, no signup.
Onefinity cutting areas, precisely
Nominal sizes from Onefinity's product pages (onefinitycnc.com, checked 2026-10). Onefinity lists the exact figures slightly over nominal on some models (the Journeyman as 48⅛" × 32⅛", for example), and specs differ a little between Gen 1 and Gen 2 machines, so check the page for your generation or jog your machine to its limits:
- Woodworker: about 32" × 32"
- Journeyman: about 48" × 32"
- Foreman (Elite): about 48" × 48"
- Z: Elite machines use the Z-20 slider with 165 mm of travel; usable cutting depth is less than that (Onefinity lists 5¼" for the Journeyman)
The Journeyman is a Woodworker with 16" more X travel; Y is the same.
Worked example: 11×15 cutting boards on a Journeyman
Run through the optimizer against a 48" × 32" bed, a ⅛" (3.175 mm) router-bit kerf, and rotation allowed:
- 10 requested 11" × 15" cutting board blanks
- 8 fit in a single bed load at 85.9% bed utilization
- The remaining 2 go on a second load
Area math (48 × 32 = 1,536 sq in ÷ 165 sq in per blank ≈ 9.3) says 9. The rectangles say 8: they have to sit whole on the bed with a bit-width gap between them, and the leftover strips are too narrow for a ninth. The answer is the same at the listed 48⅛" × 32⅛", so it doesn't hinge on the last fraction of an inch.
One caution: when a part is an exact fraction of the bed (three 16" parts across a 48" bed, say), the kerf can decide whether the last one fits. Enter your machine's measured travel, not the rounded name, when you're that close.
How to use it
- Open the optimizer — the button below preloads a 48" × 32" sheet labeled "Onefinity Journeyman bed" (swap to 32" × 32" for a Woodworker before you run it)
- Add your parts: width × height × quantity for each shape you're cutting
- Set kerf to your bit diameter — ⅛" (3.175 mm) is typical for a router bit
- Allow rotation unless grain or engraving orientation is fixed
- Run it. You get the per-load part count, bed utilization, and a layout diagram you can export as DXF for your CAM software (EZNESTING places rectangles; it doesn't generate toolpaths)
Where this fits among the tools
This page is about the Onefinity's own bed sizes. For a general router-bed workflow across brands, see the CNC router nest optimizer; the Shapeoko cutting area page covers Carbide 3D's beds if you're comparing machines. Background on the packing problem underneath any of these layouts is in what bin packing means for cut lists and nesting optimizer use cases.
