About GRBL
Lite version of GRBL OTG Bridge.
Same as the big one except you can't run a GCode program.
Prerequisites:
GRBL>=0.9 Android>=6.0.
COMPATIBILITY AND DURABILITY
The application supports the full GRBL protocol from version 0.9 while fully leveraging the improvements of version 1.1 and extended HAL (Hardware Abstraction Layer) capabilities.
GRBL-OTG Bridge is compatible from Android 6.0 :
This technical choice allows you to reuse your dormant Android devices to turn them into high-performance and dedicated CNC controllers.
ARCHITECTURE AND INNOVATIONS
🔹 Easy Probe :
An instinctive approach to probing.
You retain full control of the movement until contact or until a voluntary manual stop.
This system simplifies zeroing by breaking free from rigid probing macros :
Precision at your fingertips.
🔹 Smart Coordinates Agent :
Upon connection the agent aligns the WCS and measurement units (G20/G21).
It proactively identifies risks related to homing or accidental loss of G92 offsets during a session and warns you so that nothing escapes you.
You have the information and the means of action.
🔹 Macro M6 :
You can define a tool change macro for each profile.
The editor allows you to write it or load a G-Code file.
