Released 20 October 2026. Version 1.1 build 360 of CNC3D Commander and the CNC3D Design Suite: 10 new features, 19 bug fixes. Download the latest build (free, Windows).

New features

• Design Suite: a new Machine menu lists every CNC3D machine (work area, speeds, collet size) plus your own, and picking one offers to size the canvas to its work area.

• Each machine remembers the Job type you last used with it, and exports are checked against its limits (stock size, cutter shank, feed rates and depth) before the G-code is written.

• Tool Library: every cutter now has a Shank size, filled in for the whole CNC3D TurboCut range, so the machine check knows what fits your collet.

• The AI Assistant respects the picked machine when it chooses cutters and feeds.

• Generate 3D model: reliefs pick up finer surface detail from the picture, open at a 6 mm depth, and typed numbers in the relief editor refresh the preview as you type.

• Every CNC3D program and component is now digitally signed with the CNC3D Pty Ltd certificate for smoother antivirus and SmartScreen checks.

• Commander: the New machine wizard now works on FluidNC controllers and comes back after Reset Machine Wizard on FluidNC and other ESP32 boards, not only on NightHawk; Help > Support Topics links the article on bringing it back.

• Commander: the New machine wizard no longer restarts your controller partway through setup on any controller type; the few FluidNC settings that only change at start-up are saved and take effect the next time the controller is powered on, and the wizard tells you so.

• Design Suite: a new shape picks up the feed rate and spindle speed of the shape you drew before it.

• Design Suite: laser, plasma and knife jobs honour the Stock menu Z zero (Machine Bed) the same way router jobs do.

Bug fixes

• Design Suite: a shallow bend between two straight edges is no longer rounded into an arc in the exported G-code and the Cutting View.

• Commander: wizard steps that wait on the controller (travel capture, factory profile) no longer stall while the setup prompt is open.

• Commander: loading a factory machine profile no longer stops at the first setting your controller does not support; everything it accepts is applied and you get a list of what was skipped.

• Commander: the wizard direction test only asks whether the axis moved the right way after the move has actually happened, explains a refused move, and no longer leaves the controller in relative (G91) mode.

• Commander: the machine limits step saves the right travel on machines that home to the back right corner, so soft limits no longer trip after the wizard.

• Commander: if homing fails during setup the wizard stops and points you at the limit switch wiring instead of waiting forever, and connecting to a controller with no extended settings no longer stops partway through.

• Commander: after loading a factory profile in the New machine wizard, the firmware update offer and the SD job sync window no longer pop up a second time on top of the wizard.

• Design Suite: tabs now appear on every profile cut that goes through the stock, sit exactly where you drew them, and are never drilled through by the plunge or the ramp.

• Design Suite: identical shapes with the same toolpath cut identically, and shapes stacked on top of each other cut in the order you see them on screen.

• Design Suite: the number of passes is exact (6 mm at 0.6 mm per pass is ten passes, not eleven) and the last pass lands on the total depth.

• Design Suite: the cutter lifts to Safe Z before every tool change, and the Safe Z in your post-processor header and footer respects the Machine Bed Z zero.

• Design Suite: pocket cut offsets, outside cuts on small pins, inside cuts on small holes, ball-nose profiles, rotated groups and open lines all cut where the drawing shows them.

• Design Suite: a V-carve on top of a pocket of the same depth no longer disappears, and V-bit walls are no longer widened.

• Design Suite: numbers typed into the toolpath panel and tabs dragged on the canvas are kept when you export or save without pressing Enter.

• Design Suite: small point and curve-handle adjustments can always be undone and redone, including straight after a Sculpt.

• Laser, plasma and knife: shapes inside a rotated group cut where they are drawn, default lead-ins and lead-outs sit in the waste instead of on the part, and the knife lifts between the contours of a shape.

• Laser: open paths cut once per pass with no stroke back across the opening, straight lines and polylines can be profile cut, and fibre multi-pass heights count from the cut height.

• Knife: rectangles and ellipses drawn with the shape tools are now cut, and the lead-out follows the handle you dragged.

• Laser pictures: the raster starts from the stock start point, no longer drops a pixel per row, and the profile kerf is half the beam width.
