One wire is just a pulse out for speed.

Sorry the zip with the schematics I had downloaded had version 1.5.6! despite it saying 1.5.7 on the zip! Yes I will be getting the 5.7 version. I will be using one of these I have lying about: http://www.ebay.co.uk/itm/281218773432 and another for 5V stuff like LEDs and that suff. raspberry pi possibly.

Will do when I get the parts soon! Might work or might have a smouldering heap of scrap!

Great! Thanks for the insight thats good to know. Will I still need to do anything with the MOSFETS of can I leave them as is? Also the fans: https://www.dropbox.com/s/vfde6674tmi6paj/Screenshot%202014-07-25%2018.42.42.png is part of the schematic

If i remove all voltage regulators and discard the switch and power jack could I put 24V into the UM shield? I know that for the hotend and HBP I would possibly need to take off the MOSFETs and put them onto a daughter board due to current issues and the tracks?

Finally someone has tried what I was thinking somewhat. Glad it works!

I could cry! Someone just printed a carriage for me for the V5! :( *goes off to cry*

These relay ways of doing the hotbed switching are horrible! You don't need to buy anything extra only need a small bit of stripboard! Just a case of removing the MOSFET putting it onto the external board with the other psu. No need for a clicky relay. Also gives the option of pwm.

The only place other than Ultimaker to buy them ready made was aliexpress. Arrived perfect!

Correct. I am doing a self sourced Ultimaker. . Www.callum-burns.co.uk for my blog and how I am getting on. I need to add a new blog poat as I have gotten some more parts. . So far it's been fairly easy to get parts but some parts I have had to get from china. :(.

Hi what is the least amount of torque I could get away with on the X axis? I have found a nice small motor here that has a torque of 2.5NM? http://www.ebay.co.uk/itm/281319606945 is what I'm looking at. edit by gr5: fixed link

This i what I wa planning to do: Remove the Bead MOSFET from the UM board Take a wire off the gate pin on the UM board. Solder the FET you have taken off of the UM board onto a small bit of strip board. Take the wire that you have put onto the gate pin on the UM board onto the gate pin of the MOSFET on the external board. Tie your 24V PSU and the 19V side GROUNDS (Drain on the MOSFET) together. Put HB in between the Source of the MOSFET and your 24V PSU. Cost: Nothing if you have a bit of strip board lying about. There is no need for another MOSFET or SSR. Uses parts that you have already too. Will upload a diagram soon.

Alas it's only a theory for now but there is nothing to say why it won't work! So long as there is a common ground. Until I get my UM control board then sadly I can't test it unless someone else wishes too.

E3d here in the UK sell couplings.

You can take off the MOSFET put it on a remote PCB feed 24v into that take a wire off the gate pin onto the UM board were the FET came from. No extra cost apart from a tiny bit of strip board. simples.
