# Klipper Toolboard
|
|
A very small 3D printer board for use on a toolhead.
|
|
|
|
|
|
|
|
|
|
Features:
|
|
* TMC2209 driver
|
|
* STM32F042C6T6
|
|
* Two MOSFET drivers fans
|
|
* One bigger MOSFET driver for a hotend heater
|
|
* Thermistor input
|
|
* One endstop
|
|
* CAN bus
|
|
|
|
Main power is 12-24V
|
|
|
|
|
|
The CAN Bus is not terminated, instead it uses 4 wires, termination should be done at other end.
|
|
|
|
It uses an external 5V switch regulator.
|
|
|
|
All done in KiCad
|
|
|
|
Possible issues:
|
|
|
|
* Is the cooling for the TMC2209 adequate?
|
|
|
|
|
|
Change ideas:
|
|
|
|
Is the endstop useful? Better with a servo output?
|
|
|
|
|
|
Use an STM32F103 instead? Pinout is the same. F042 has klipper CAN support. Porting the klipper code to F103 should not be that hard.
