[ELECTRON] Proposed new club + Arduino meet up

The linked section is correct in that this is the correct place to go to for
the standard Prusa.  I reckon that most of the parts in this source will be
fine.  

That is not to say that this is the only place that parts can be picked
from.

Since you mentioned vertexs, there are some variations available at
thingiverse.  Some claim to be easier to print.  I would think that as long
as we use parts that are compatible with the original device we won't get
into too much trouble...

Hi Roy,

This is not something that is going to happen in days, aside from everything
else motors are likely to take weeks to arrive ( the supplier I order from
does not have them in stock, took the money though). We are certainly not in
a hurry. The next meeting is not till the 17th of next month. If we a few of
the parts it would be a fantastic.

The parts have been taken from here.

http://www.reprap.org/wiki/Prusa#Printed_Parts

The reprap communicably has given this link when printing on other devices

https://github.com/prusajr/PrusaMendel. (Blair please correct me if I have
totally missed the ball)

I really hope this helps. It is a bit of chicken and egg situation, untll we
have built one we are winging it.

You can if you wish register with goshg.org.uk and edit the post for the
reprap. This goes for anyone.

If this does not help, please let me know and I will ask people far more
knowledgeable than myself.


Let me know how you get on.

Thanks

Kieran.
