Why it exists
Shop software should feel like it belongs in the shop.
Jotteea Nester was built from the practical side of CNC work: load the file, set the sheet and cutter clearance, use common-line/shared-line nesting where it helps, choose copies, review the nest, build toolpaths, and export what the machine or customer needs.
It is made for sheet-good jobs where speed, material use, shared cuts, clarity, and review matter. The workflow is intentionally page-based so customers can move from setup to preview to machine settings to export without hunting through a crowded screen.
Watch it work
See the newer Jotteea Nester workflow in motion.
This newer software preview shows the workflow customers care about: importing parts, reviewing the nested sheet, checking common-line/shared cuts, and understanding the flat toolpath preview before export.
Built around the real shop problem
Common-line nesting and shared-line cutting help avoid cutting the same edge twice when parts can share a cut. The grounded preview keeps rapids, common cuts, profiles, drills, tabs, leads, and ramps clear before the file goes to the machine.
Sales points
One workflow from CAD file to shop output.
The goal is simple: reduce the back-and-forth between drawing, common-line nesting, tabbing, checking, and exporting.
Part copies and names
Name parts and set copy counts so the preview and output use clear customer-friendly part labels.
Tabs, dogbones, and clearances
Apply automatic tabs, adjust tab settings, and support interior dogbones during nesting where needed.
Common-line nesting + shared cuts
When parts can share an edge, common-line cutting helps reduce duplicate profile cuts and keeps the nested sheet efficient.
Drill grouping and tool assignment
Group holes by detected diameter, assign drill tools line by line, or let the cutter route holes that match or exceed the cutter size.
Tool Database
Save tool numbers, names, diameters, feed, plunge, spindle RPM, jog speed, and type so posts can use tool-specific settings.
Flat toolpath preview
Use a grounded static preview to review dotted rapid moves, common-line/shared cuts, profiles, drill/hole paths, engraving, leads, ramps, and tabs.
Export DXF and machine code
Export nested-part DXF or selected machine code after the job has been built and reviewed.
Post processor support
Need a new machine post or a fix to an existing one? Send machine details, sample work, and current post files for review.

Flat grounded toolpath preview
Color-coded output keeps dotted blue rapids, solid blue common-line/shared cuts, red profiles, purple drills/holes/open vectors, green tabs, yellow lead-ins, and orange ramps visible without a confusing 3D view.
Setup + Parts
Load CAD, enter sheet and cutter settings, set copies, name parts, and start nesting.
Machine settings
Material, depths, safe Z, leads, ramps, Tool Database selection, drill groups, and engraving settings in one place.
Export
Export nested DXF or machine code after the toolpaths are reviewed.
How it works
A simple five-page flow.
- Setup + Parts: load geometry, set sheet size, units, copies, names, and defaults.
- Nest Preview: review the sheet layout, spacing, part labels, and common-line/shared-cut opportunities before toolpath work.
- Machine: set depths, leads, ramps, Tool Database tools, drill groups, and engraving/open-vector options.
- Toolpath Preview: verify a flat, color-coded preview including rapids, drills, cuts, tabs, leads, and ramps before export.
- Export: save nested DXF or machine code for the selected post.

Before you cut
Practical notes for CNC customers.
What is Jotteea Nester best for?
Sheet-good nesting workflows where you need to lay parts out, use common-line/shared-line cutting where practical, add tabs, check toolpaths, and export quickly.
Does it replace operator judgment?
No. Always verify the posted code, machine setup, tools, zero position, clearances, and preview before cutting.
Can it export more than machine code?
Yes. The workflow includes nested DXF export along with selected machine-code output.
What about drill holes and engraving?
Machine settings include drill grouping, Tool Database tool assignment, cutter-milled hole handling, and open-vector/engraving options.
