🆕 Upcoming CNC Lathe Machine DLC

We’re actively working on a brand-new CNC Lathe Machine DLC, bringing realistic turning operations and new workflows to the simulator.

📅 Release date: 3 March

🐞 Fixed

📝 Backspace Glitch in CNC Program RUN Fixed an issue where pressing Backspace could unexpectedly jump the selection to a previously selected line.

G41 + G02/G03 Arc Issue Tool radius compensation (G41) should now work correctly with consecutive arc commands (G02/G03).

🟥 CNC Console Error Display Fixed incorrect HTML output in the CNC console — errors are now properly displayed in red, as intended.

🧵 LATHE Threading Tool Teleport Bug Fixed an issue where pressing the Space key during threading could cause the tool to teleport away from the scene.

🐞 Axis movement with keyboard

Fixed an issue where reaching an axis movement limit would display a tooltip that temporarily blocked keyboard movement for several seconds. Axis movement now continues to work normally even while the tooltip is visible.

🐞 Fixed, when Chinese characters were not shown correctly.

General bug fixed and improvements!
