Overview
Motherboard 2layers v2 is an open-source printed circuit board by hackclub, from the hackclub/forge-printer repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 113.4 × 55.3 mm with 87 parts on 123 nets, routed with 932 tracks and 102 vias.
It is built around the TMC2209SILENTSTEPSTICK, AMS1117-3.3 and USBLC6-2SC6, with the AO3400A, WS2812 and FDMS86202 among its other parts. Its parts include 32 capacitors, 12 resistors, 9 ICs, 5 transistors and 5 connectors. It belongs with the robots and motor control and computers and single-board computers boards and the STM32 boards of this library.

About the Forge Printer
The Forge Printer is a fast, inexpensive, and compact cantilevered 3D Printer. More details soon!
Specifications
These are Forge's specifications as of June 10, 2025. We're currently still in the process of building MK2. More details will be published soon.
- STM32F405RGT6 32-Bit MCU
- TMC2209 Stepper Drivers
- Reduced Motor Noise
- Sensorless XY homing
- TZ-E3 Hotend
- 300°C Maximum Temperature
- Designed around the Bambu Lab X1C hotend
- 30mm³/s max flow rate
- 120x120x140mm Build Volume
- Up to 100°C heated bed temperature
- Magnetic Textured PEI Plate
- MGN9C Linear Rails
- ProtoXtruder Direct Drive Extruder (DDE)
- Fully Automatic Bed Leveling using BLTouch (ABL)
- Meanwell RPS-200-24 PSU (Integrated) with a protected C14 Inlet (used on the majority of consumer 3D printers)
- PLA, PETG, TPU capable
- ABS and ASA are possible but require an enclosure and active ventilation
- Aluminum and 3D Printed ASA frame
- DragonBurner Toolhead
- Up to 500mm/s Print Velocity* *This number is an estimate, real print speeds will be updated as Forge's development continues
Firmware
-
The Forge Mainboard will run on Marlin Firmware. (Custom, open source Forge Firmware had been planned but development has been halted as as of right now it is unrealistic)
-
The Forge Mainboard is supported by Klipper
- Using the Forge Printer with Klipper will be possible! The latest revision of the Forge Mainboard (2 layer PCB version) runs a STM32F405 which is fully compatible with Klipper! Additionally, we'll be providing a Klipper WiP configuration file and OrcaSlicer profiles (Coming Soon) for you!
- SBC Info:
- A Raspberry Pi Zero 2W will be required for Klipper. You can also use another SBC (that can run MainSailOS or Fluidd) with the same form factor. However, the Zero W (1st Gen) is highly not recommended due to performance limitations. Larger SBCs like the Raspberry Pi 1/2/3/4/5 boards are not compatible due to size limitations. We'll be providing a Raspberry Pi Zero Bracket available to print closer to MK2's launch! The Forge Mainboard connects to the SBC via GPIO to GPIO, therefore, SPI touchscreens are not recommended.
Additional notes
- The full Forge Printer and Mainboard BOM will soon be at the bottom of this doc. The Forge Printer BOM will not be available until we begin prototyping. However, the BOM for the Forge Mainboard is currently available as a CSV in
Electronics/Motherboard/billofmaterials.csv. - The estimated value of the Forge Printer is $200-$300, but this estimate will change over time (Additionally, tariffs may impact this cost in the future).
- However, our goal is to offer Forge for free for teens 18 and under (details on how will come out soon) **
- Currently, Forge's parts and components are planned to be manufactured by Siboor, a well-established supplier of 3D Printing components.
- Forge is designed in Onshape. Check out the 3D model!

- Currently, the Forge Project is GPLV3 (General Public License)
- Anybody is allowed to freely use, advertise, modify, copy, or distribute any Forge designs or software as needed, with the condition that any public distribution or use of Forge software/design must also be open source and use GPL.

Questions
How big is the Motherboard 2layers v2 PCB?
It measures 113.4 × 55.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Motherboard 2layers v2 use?
87 parts, built around the TMC2209SILENTSTEPSTICK, AMS1117-3.3, USBLC6-2SC6 and AO3400A. 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 Motherboard 2layers v2 KiCad files?
From the hackclub/forge-printer repository on GitHub, at the commit this page was made from: the board is Electronics/Motherboard/CurrentVersion/motherboard_2layers_v2.kicad_pcb and its schematic Electronics/Motherboard/CurrentVersion/motherboard_2layers_v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motherboard 2layers v2 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
