Burin 0.10.0

A new logo, and the interface in its colours. The engraved orange block replaces the old icon. Orange marks what is active or chosen. The panels take the logo's slate (dark look) or cream (light look). The tool families keep their own colours: shapes orange, sketching and 3D gold, moving blue, editing teal, repeating violet, machine files green.

Toolpaths checked against real saved jobs.

• Leads into small holes: a lead that would reach into the part is shortened, or left out when even a short one doesn't fit. Before, a 2.5 mm lead in a 5.2 mm hole cut 0.5 mm into the far wall. Leads now also come in square to the loop's true direction.
• Profiles: a loop that starts at a corner starts where the corner's arc begins. Of 120 saved profiles, those differing by more than 0.3 mm went from 15 to 7.
• Ring pockets: the passes start on the side where the shape starts and run out from the middle in a line. 12 of 39 saved pockets now come out the same (3 before).

Only a few real jobs have been cut with Burin so far: check every file in a simulator, then run it in the air, before you cut.

Windows: run the .exe (it isn't signed: More info > Run anyway). Linux: make the AppImage executable, then run it.

Burin 0.9.9

Machining fixes from comparing with real saved jobs.

• V-Carve with an end mill: a flat cutter now follows each shape once, its radius inside, at the flat depth. Before, it swept the whole shape with rings a few hundredths of a millimetre apart (on a plate of engraved text: 1,410 lifts and 151 m of cutting, now 12 traces and 1.7 m).
• Drilling: the tool now comes down fast to the plunge gap above the material before each hole, instead of drilling slowly from the safe height.
• Pockets: new "Second raster at 90°" option, which cuts the rows again across the first. Tiny specks of rings in the middle of a stroke are left to the passes around them, which saves lifts.

Lighter 3D in the browser. The web version starts its preview on Light quality, carves on half the points, keeps the finished picture under 1.5 million pixels and works in shorter slices, so the page stays responsive while the view turns.

Burin 0.9.8

A look of its own. The left panel's sections are a strip of icons along the window's edge, Machining keeps its toolpaths on the left too, and each family of tools has its colour. A light "workshop" look can be chosen in the preferences, beside the dark one.

Finding your way: Ctrl+K finds any command by name; a card gives the selection's position, size and layer, typed in directly; the start screen shows drawings of your recent projects and models to start from (name plaque, coaster, small box), their toolpaths ready.

Machine files: a corner tolerance for LinuxCNC (G64 P) in Save Toolpaths, remembered with the other choices when you save; About gives the version and how the view is drawn.

Fixes: another project opened in the same window is shown whole; the browser version opens files in Firefox and Safari, and no longer mixes an old and a new half after an update.

Burin 0.9.7

Browser version: opening files works again in Firefox and Safari. These browsers only open a file picker straight from a click; Burin now shows a small box with a Choose button there. Chrome, Edge and other Chromium browsers open the picker directly, as before.

The version shows on the start screen and in Help > About, which also gives the licence and the website.

Save Toolpaths remembers "slow down in tight corners" and the LinuxCNC corner tolerance, kept when you save, as for "one file".

Burin 0.9.6

Machine files follow their toolpaths again. When writing curves as arcs (G2/G3), a long straight wall between short corner pieces could become one wide, almost flat arc, up to 1.4 mm off the cut: material left on one side, the outline crossed on the other. It was found on a real pocket cut on a CNC. Fixed.

A new safety check before saving: each machine file is read back as the machine would read it and compared with its toolpath. If they're more than 0.2 mm apart, it's flagged as a danger and the save stops until you decide.

Pockets: the rings are cut branch by branch and go on to the ring around them without lifting, as the original program does. The corners the rings miss are cleaned as each ring goes by, instead of long crossings of the pocket at the end.

LinuxCNC: a new option in Save Toolpaths writes a corner tolerance (G64 P, 0.03 mm at first) for the generic G-code outputs.

Burin 0.9.5

Pockets: when the last pass is as thick as the whole cut, Burin no longer makes an extra pass at the surface that cut nothing (text pockets lifted twice as often).

Opening .crv3d projects: a two-sided job opens as two-sided, turned over the same way.

Menus: the empty extensions menu is gone.

Burin has never driven a real machine yet: check every file in a simulator, then run it in the air, before you cut.

Burin 0.9.4

Two workspaces, as in Affinity: Design to draw and model, Machining for toolpaths, preview and machine files, switched from the top left.

A look of its own: new icons, a material slab with a zero marker, renamed sections and tabs.

Pockets: raster rows go from one to the next along the edge, region by region; offset pockets reach their corners without lifting.

New projects start from the material of the last new project.

Browser version: the 3D view no longer freezes the page after each move.
