In the last update, it was mentioned that there were a few components left to make the control board complete. It can be said that the board is two steps (ignore the pun) closer to being complete. Four step stick stepper motor controllers have been purchased from china and have arrived in good condition (although to the wrong address!) and assembled and installed to the Sanguinololu.
The next task was find / adapting a 12v power source to the system. This implementation accepts a standard PC atx 2.1 power supply and requires only the 12v auxiliary power connector for the CPU. As it does not look tidy and can be difficult to manage, the extra unneeded cables and connectors have been de-soldered from the PSU PCB. It is a very bad idea to simply cut of cables from the PSU as you may end up shorting the system out somewhere down the line.
The other set of wires left connected are a single ground connection (black) and a power on (green). This is so the PSU can actually be turned on using a toggle switch of some description.
Again at the end of this update the only thing left to do is find two suitable MOSFET’s for the heat bed and hot-end and some cable crimps (The headers and sockets have already been purchased).
