Sorry - Bath Univ. has gone offline for the weekend - some big upgrade. This means that the redirection of will be a bit dodgy for a couple of days. Shouldn't happen again.

Lost units

This post is to ask you, the RepRap community what parts are readily avalable:

In 1824 we, the Brits, came up with the Imperial measurement system and in keeping with the times, spread it around a bit. In 1995 we officially became an SI nation and now I, fully metricated, have no clue what the imperial spread is...

Thanks to Vik's suggestion I'm trying to make my corner block (see previous post) fully compatible with both units. The closest bits I've found to my ø8 rods and M5 nut/bolts are: ø5/16" bar and ø3/16" whitworth (?) nut and bolt combo... so how easy are these for you guys to get hold of?

Universal PCB update

I've wired the first Universal PCB I made as a stepper controller, modified the driver software so it will work both this and the old design, and fired it up with a little ex-HP-printer stepper connected as a test - seems to work.

In the University tomorrow Ed and I'll put it in ARNIE and see how hot the L298N gets (the 754410 gets jolly hot...).
