Docs & manuals for the open DIY motorized camera slider stack: build guides, wiring, pinouts, UART protocol, user manuals (JKSlider/B4Slider), architecture. Covers all four repos together — SliderCtrl (Pico panel), SliderMC (STEP/DIR motion), SliderWeb (Pico W phone/tablet UI). For filmmaking makers: rails, steppers, timelapse, open firmware.

Open-source Wi‑Fi UI for DIY motorized camera sliders — MicroPython on Raspberry Pi Pico W / Pico 2 W. Control move, speed & status from phone or tablet (captive AP or STA). Part of one stack with SliderMC (STEP/DIR motion), SliderCtrl (physical panel), and SliderDoc (build guides). Same UART protocol; STEP/DIR builds for filmmaking makers welcome.

Open-source DIY motorized camera slider UI firmware for Raspberry Pi Pico — MicroPython panels (JKSlider/B4Slider) with OLED, SPEED/ACCEL knobs, marks, loops, timelapse & camera trigger. Part of one stack with SliderMC (STEP/DIR motion), SliderWeb (phone/tablet Wi‑Fi), and SliderDoc (build guides). Your rail, steppers — filmmaking makers welcome.

Experimental grblHAL motion control for ESP32-S3: S-curve, 1 kHz Fixed-Time Motion, ZV input shaping and trajectory smoothing for CNC.

Open-source motion controller for DIY motorized camera sliders on Raspberry Pi Pico (C++/FreeRTOS): STEP/DIR steppers, PIO timing, sine ramps, live retarget, homing, soft/hard limits & EMO. Part of one stack with SliderCtrl (panel UI), SliderWeb (phone/tablet Wi‑Fi), and SliderDoc (build guides). A4988, DRV8825, TMC & similar — filmmaking makers.

Open-source Dragonframe DMC v2 USB bridge for DIY motorized camera sliders on RP2040-Zero (C++/PlatformIO): path play, GIO, camera trigger & live DMX512. Part of one stack with SliderMC (STEP/DIR motion), SliderCtrl (panel UI), SliderWeb (phone/tablet Wi-Fi), and SliderDoc (build guides). Arc stop-motion — filmmaking makers.

Open-source PC/ESP32 host for DIY motorized camera sliders — CPython (or MicroPython on ESP32) web UI, UART to SliderMC, F-curve timeline, timelapse and session control. Part of one stack with SliderMC (STEP/DIR motion), SliderCtrl (physical panel), SliderWeb (phone/tablet Wi-Fi), and SliderDoc (build guides). Filmmaking makers welcome.
