gSender is a desktop application for connecting to and controlling CNC machines running Grbl or grblHAL firmware.
It has a streamlined interface intended to remain approachable for routine jobs while providing deeper machine setup and machining tools when required. Besides sending prepared G-code, gSender covers probing, machine calibration, tool changes, surfacing and other tasks commonly performed around a CNC job.
This is free and open source software.
Key Features
- Supports Grbl and grblHAL controllers.
- Four-axis digital readout with direct coordinate entry.
- Incremental and continuous jogging with diagonal XY movement and configurable jog presets.
- 3D toolpath visualisation can be used before connecting to a machine.
- Displays useful information about loaded jobs including dimensions, feed and spindle ranges, tools and estimated machining time.
- Probing tools support multiple directions together with continuity checking.
- Includes zero-setting, homing and rapid movement to predefined positions.
- Provides spindle, laser, mist and flood-coolant controls with live overrides.
- Surfacing, axis calibration and movement-tuning tools help with machine setup and maintenance.
- Supports tool-change workflows and automatic tool-changing configurations.
- Macros can use variables, keyboard shortcuts and customized controls.
- Includes controller firmware and EEPROM configuration tools.
- Can resume jobs from a selected line and outline job boundaries before cutting.
