README.mdChess Printer
A chess bot, but on steroids.
A completely custom-designed 3D printer control board with an ESP32 MCU. Designed to control a CoreXY printer, but can probably be adapted to any kinematic system.
Warning: This is an experimental project with no gurantees - use at your own risk and discretion!
Notable Features
- 6 stepper drivers (labelled X, Y, E0, Z1, Z2 & Z3)
- Designed for TMC2209 drivers
- 1-wire Serial communication with all drivers supported
- ATX & screw terminal power input
PS-ONcontrol (standby & emergency kill poweroff supported in Marlin)- MCU can be powered from
5VSBATX power rail with jumper selection (DO NOT power via USB and5VSBconcurrently - doing so will almost definitely damage something!)
- ESP32 MCU (DevKit-C footprint)
- I2S stepper stream
- 2x daisy-chained
75HC595shift registers
- 2x daisy-chained
- I2C LCD
- 1 hotend & 1 heatbed thermistor input
- 1 high power MOSFET bed heater & 1 heatbed output (for external relay/SSR)
- 1 controllable & 1 always-on fan output

Questions
How big is the ChessBotController PCB?
It measures 71.3 × 95.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ChessBotController use?
55 parts, built around the 74HC595 and IRLZ44N. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ChessBotController KiCad files?
From the cryptoAlgorithm/chess-printer repository on GitHub, at the commit this page was made from: the board is ChessBotController.kicad_pcb and its schematic ChessBotController.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ChessBotController design in my own project?
Its repository states no licence, so its author keeps all rights: ask cryptoAlgorithm before reusing the design.
