gSender by Sienci Labs is a powerful, free, open-source GRBL-based controller software designed to send G-code to your CNC router. Configuring it correctly ensures precise carves, protects your wasteboard, and prevents catastrophic tool plunges. Here is how to set up gSender for flawless CNC carving. 1. Installation and Firmware Connection
Before running your project, gSender needs a solid communication link with your CNC hardware.
Download the App: Get the version tailored to your OS (Windows, Mac, Linux, or Raspberry Pi) from Sienci Labs Documentation.
Match Baud Rate: Open Config ➔ Basics. Set the Baud Rate to your machine’s factory specification (usually 115200 for standard GRBL boards, though some controllers like X-Carve Pro may require 57600).
Select Firmware Fallback: If auto-detection fails, manually specify your board’s core language (e.g., grbl or grblHAL) under the firmware fallback panel.
Isolate Connection: Ensure competing CNC interfaces like Easel or Universal Gcode Sender (UGS) are completely closed to avoid serial port conflicts. 2. Tailor Your Jogging and Shortcuts
Accurate machine positioning prevents crashes into clamps and material edge mismatches.
