gSender: connect to and control grbl-based CNCs

gSender is a feature-packed CNC interface software designed to be clean and easy to learn while retaining a depth of capabilities for advanced users. Its development was begun in 2019 out of a passion for hobby CNC machines: an interface reimagined to suit the needs of the at-home CNC user.

• Totally free
• Accepts standard, grbl-compliant g-code from all the common CAM programs
• Designed to be generic so any standard grbl or grblHAL CNC will work
• Expands its UI to the needs of your CNC by recognizing what features it's capable of
• Works on as wide a range in computing systems as possible (low-end PC to RasPi, leveraging Electron)
• Used to be based on the popular CNCjs controller interface but has since been mostly re-written

Our core principals during development have been to:

1. Make any CNC feel easy to use no matter your previous experience
2. Substitute CNC jargon with simple language when possible
3. Keep the interface flexible to accommodate any common CNC machine
4. Maintain 'power tools' and customizability for advanced users
5. Prioritize interface reliability over new features
6. Otherwise continue pushing forward in any way possible to advance the CNC experience
