After a month of caffeine-fueled late nights and tag-teaming with Claude, Codex, and Gemini (with occasional frustration and yelling at the screen 
)… I finally did it.
ncSender is now ready for public testing! 
It’s built with simplicity, speed, and extensibility in mind — no more monolithic all-in-one beast. Here’s a quick look at what’s inside:
Key Features
-
Plugin architecture — Extend functionality instead of big code base core. -
3D Touch Probe — Supported right out of the box. -
Feature-packed G-Code virtualization — Includes multi-view options like Spindle View and Auto-Fit, plus Out-of-Bound indicators and on-screen warnings to keep your jobs in check. -
Refined terminal — Cleaner and more powerful for advanced users. -
G-Code Viewer — Displays crossed-out executed lines so you can track your job in real time. -
Touchscreen optimized — Perfect for kiosks or tablet setups. -
Safety first — Long-press required for critical commands to prevent “oops” moments. -
Auto reconnect — No more connect/disconnect drama; ncSender silently retries in the background. -
Improved G-Code Visualizer — Home indicator, real-size workspace, and cross-section view of your machine area.
Notes
I mainly use this myself and with a few guinea pigs 
, so expect some rough edges.
If you find bugs, please report them on GitHub — feedback helps a ton!
Tested with my AltMill + SLB-EXT setup running the latest grblHAL firmware (not SienciHAL).
