What's new in 0.5.2

Oval sign sample. Generate → Sample projects → Oval sign makes an oval plate with "PutiaCNC" V-carved in the middle, "toolpath studio" and "free open source software" following the inside of the oval, a fine engraved border and four holding tabs, using your own tools (the V-bit nearest 60° for the name, an engraving bit for the fine work, a flat end mill for the cut-out). It needs a work area of about 260 x 170 mm. The same project is in the repository under examples/projects/.

Cleaner V-carve with a flat floor. The flat end mill is round, so it could not reach sharp tips and narrow parts of the floor, and they came out rough. The V-bit now clears exactly those parts, with its tip at the flat depth, and a note says so.
"Clear with" does something when you pick it. Choosing an end mill sets the flat depth to half the operation's depth (before, nothing changed until you set a flat depth), and a new button next to the tool removes the end mill again. "Flat depth" is shown only while an end mill is chosen.
Finger-joint box: more room between the plates. The plates were 6 mm apart, so the strip of stock between two cuts was a sliver that broke away and the holding tabs had nothing to hold to. The sample box and the Box with finger joints tool now leave at least 12 mm between plates (the sample box is a little smaller for it).
SVG import reads the installed fonts only when the file has text, so a drawing without text no longer waits for the font scan, which takes seconds on a machine with thousands of fonts.
One more warning in the list. "Custom feeds and speeds held to the machine's limits" joins the warnings list instead of appearing as an information line on the Notes tab.

Text running out of the operation cards. A hint next to the Flat depth field could not wrap, so it widened the V-carve card past the panel and cut off the tool summary below it. The hint now has its own line, and a test checks every kind of operation card for text running out of the panel.

The macOS build uses the macos-15 runner (GitHub retired macos-14 on 2 November 2026).
