Improved board in the works

A project log for Huvud, a 3D Printer Tool Head Controller Board

World's smallest (42x42mm) 3D printer controller board for use on a direct drive hotend. Made to run Klipper firmware.

While it is not really possible/viable to produce any more Huvud v0.5 boards at the moment I am slowly working on an improved v0.6. Many component are very very hard to find, and if you manage to find any they are ridiculously expensive.

The main improvements on this new board are:

I was just researeching moving my Voron to Duet3 to use a toolhead board and stumbled across this. If the project is still going strong I'll happily wait for the next version to arrive.

Adding a jumper or solder bridge for the 120 ohm termination resistor would be useful too.

Hi there, I built one of the new versions for my Voron to control my Afterburner Extruder aside two SKR1.4 boards. By now I'm trying to fix problems mostly on my side being new to Voron and Klipper but I must say the board is fantastic and integrates perfect into this scenario bringing all functions I need. As I'm building a 400mm version and because of high temperatures inside the chamber I was sceptic of USB connections being the right choice and find CAN more reliable. I did some modifications to fit behind the stepper (other connectors) and designed a mount to get the Igus chain connected. As soon as everything is working I will make them available. Great work and thank you so much!

Great improvements, if they are available while im building my voron i'll definitely use one.

This alternative project (you probably already know about it) routes the 24v over the usb-cable. Not exactly according to spec but that makes for an even cleaner setup.
