Great project write up Peter. Just a thought as I like the red - If you leave them red will it print faster? Like Red cars go faster? :nrocks:
All looking very good,
Congrats and,
Thanks for posting.

He he, yes red makes it print faster :lol: :lol: :lol:

Joke aside, thank you very much for cheering me on. I enjoy the build and hope you all do as well.

Good Evening All,

Today I bought a PC power supply for the printer. The one I had only delivered 15A DC max on the +12V line so it was under requirements. Need another 5 to be sure.
It was not very expensive, I think about 45£ or thereabouts.

Back home and into the shop it was time for "unboxing" and opening the PSU with some expectations.

I am following these instsructions from the REPRAP site;
http://reprap.org/wiki/Choosing_a_Power_Supply_for_your_RepRap. They seem to be good and Now I am on my way intot he unknown. Will stop at this point because I want to be less tired so I don't make un-necessary mistakes. It would be bad if I blew a new PSU that I have forfitted the warranty on by opening it.

Story continues tomorrow .....

/Peter

PS,

Just had to add a comment as I got a question from a Swedish forum I am also posting on ...

If one reads further down the linked document it is possible to avoid opening the PSU to maintain warranty if so desired. But I still wanted to limit the "tail" of cables to a minimum so choose to open and cut out not wanted bits.

So there is actually two ways to go using a PC PSU, it is up to the user. Anyway, the choice of a PC PSU is quite economic compared with other types, at least I find it so.

Hi Peter E

Good to see your progress to a very smart machine. I have modded other pc atx power supplies for general use with good success. On mine I have mounted the 5v load resister inside the case where the fan can cool it, and then used a terminal block on the outside to expose the voltages generated, removing the atx connectors. This seems to give maximum flexibilty of use.

You appear to making really good progress with a very smart machine. Looking forward to seeing the results of your hard work with the first plastic prints.

Best Regards

Nice progress on the build. The end is almost in sight. I can almost smell the molten PLA already. Can I ask why you chose to buy an ATX power supply rather than get one of those CCTV / LED power supplies? A 12V 30A supply costs only £17.69 and it comes ready to plug and play - no mods needed.
