Firmware
Original GRBL project
The slider is designed for controllers compatible with GRBL 1.1. This repository does not replace the original project: it only documents settings and references for Slider-odos3d hardware.
Smart Timelapse AI Slider
GRBL 1.1 reference
Configuration, safety, and technical links for controlling the slider with compatible GRBL firmware.
Safety
ALARM, unlock, and homing
After power-up, GRBL may start in ALARM. Use $H when your build has homing ready. Use $X only when you know the carriage is in a safe position and the travel path is clear.
Before a long route, test short movements and confirm direction, endstops, and real travel range.
Base settings
Common parameters
The key values are usually steps/mm, speed, acceleration, and maximum travel. On a 60 cm slider, review especially $100, $110, $120, and $130.
App
Communication from Smart Timelapse AI
The app communicates with the controller through compatible serial Bluetooth. The expected flow is phone → serial Bluetooth module → GRBL.
Before using the full travel range
Save the base state with $$, check physical limits, confirm the carriage moves in the expected direction, and lower speed/acceleration if steps are lost.
