New features

• Commander: the AI Assistant can now write DaveScript macros, check them and open them in the Macros editor for you to review, save and run yourself.

• Commander: Claude Desktop can write your macros the same way through Commander's Claude connector, with Commander open.

• Commander: when your NightHawk can't join your WiFi, Commander now explains why in plain English and tells you exactly what to check.

• Commander: every function box now starts with Select action..., a searchable list of numbered actions that your macros can also run with action{ n }.

• Commander: Claude Desktop now finds CNC3D's tools straight away, builds a whole job in Design Suite and exports the G-code, without freezing while a window waits on you.

Bug fixes

• Commander and Design Suite: numbers are now read the same on every PC, so Windows set to a comma for decimals no longer garbles text or SVG imports.

• Commander: Job Sync skips a card file whose name is too long for Windows instead of stopping with an error every time you connect.

• Commander: the Job Sync window no longer closes itself the first time it runs.

• Design Suite: a 3D carve with roughing and a finishing Pass Depth no longer spends hours cutting air, because finishing only takes extra passes where material is still left.

• Commander: restarting a job from a line now shows the time left for the rest of the job instead of the whole job.

• Design Suite: when you set a cut for several shapes at once, holes drawn as separate shapes are cut as holes, so DXF plates come out true size.

• Design Suite: SVG files in pixels, inches or other units, inch DXF files and binary DXF files now all import, at their true size.

• Design Suite: traced logos no longer get grooves cut between their letters, transparent PNGs trace properly and an outline drawn twice (common in DXF files) is cut once.

• Design Suite: fixed toolpaths that could spoil a part: ramps on open lines, tabs on small holes or next to a ramp, knife leads, leads on a part nested in a hole, small holes cut Inside and the last lead-out when tabs are on.

• Design Suite: plasma and laser now cut each hole before its outline, plasma pierces inside the hole and its Safe Z now sits above the cut height.

• Design Suite: Pen/Knife now leaves an open line open instead of cutting straight back to its start.

• Design Suite: curves are cut as arcs again, V-carve files are a fraction of the size, plates with holes export in seconds and Pockets no longer cut a wall twice.

• Design Suite: a V-carve Pocket no longer cuts past the edge of the shape where the bit moves from one carved area to the next without lifting.

• Design Suite: the export now warns you, naming the shape, when parts overlap or sit closer together than the cutter, or a hole is too small for the bit.

• Design Suite: a laser export with nothing to burn now stops and says why; shapes inside groups no longer burn a border.

• Design Suite: an import now tells you when text in the file could not be brought in, so you can convert it to paths first.

Nighthawk Firmware Update to V3.6

• WiFi messages from the controller now say in plain English why a connection dropped or couldn't be made, instead of giving a code.

• The controller can read a card job's stock outline so a CNC3D Navigator can trace the job before you start it.

• The web interface (V2.0) now refuses file and folder names over 80 characters or with characters the controller can't use.

• Pressing Stop during a job with a PWM, 0-10 V or BESC spindle can no longer reboot the controller.

• Using the spindle stop override during a feed hold can no longer restart the controller.

• Fixed a silent restart, even mid job, that could follow a card upload cut off part way.

• A firmware update straight after a cut-off update now goes through first time.

• A G-code value with an absurd number of digits can no longer crash the controller when offsets are read back.

• A card job that disappears is now reported once instead of flooding the console with errors.

• Fixed the memory losses behind the silent restarts some 3.5 users saw after heavy SD card, web page or network use.

• Dropped or half-open network connections can no longer use up the controller's connection slots, so the web page, Commander and the Navigator can always reconnect.
