A 3D printer extruderboard
|
A very small 3D printer board for use on a toolhead.
|
||||||
|
|
||||||
|
Features:
|
||||||
|
* TMC2209 driver
|
||||||
|
* ATmega168
|
||||||
|
* Two MOSFET drivers fans
|
||||||
|
* One big MOSFET driver for a hotend heater
|
||||||
|
* Thermistor input
|
||||||
|
* Servo connector
|
||||||
|
|
||||||
|
|
||||||
|
It should be fed from the mainboard with 12-24V, 3.3V or 5V, GND, UART RX and UART TX.
|
||||||
|
|
||||||
|
Possible issues:
|
||||||
|
* Is the cooling for the TMC2209 adequate?
|
||||||
|
* How well will the UART cmos/ttl level survive? Noise?
|
||||||
|
* Does it work
|
