3D printer: common questions

What microcontroller does the 3D printer use?

The 3D printer is built around the Teensy4.1, from the NXP family.

How big is the 3D printer PCB?

The 3D printer measures 103.9 × 68.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 3D printer?

24 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the 3D printer design files?

From the lpender3672/3D_printer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the 3D printer design in my own project?

The repository has no license, so all rights stay with lpender3672. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 3D printer without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
