I've got the assembly instructions done for the Universal PCB V1.2 board you can get from the RRRF. Now available here for public comment and ridicule:




I'm part way through the extruder board instructions, so cut me some slack on that one!

Yesterday I bought a piece of copper-clad board and tried sticking it under Zaphod. The idea being to deposit a trail of CAPA on the copper and then etch the exposed copper. Unfortunately, it looks like copper makes a nigh on perfect non-stick surface for CAPA extrusions. Even after cleaning with contact cleaner and cranking up the heat, I couldn't get any CAPA at all to stick to the copper.

Looks like time for plan B; the etch resist pen.

We've updated the design on the Power and Communications board. The parts are all the same, but now its a one sided board, and much easier to fabricate. All the files have been added to subversion, and the wiki entry will be updated with new pictures later this week once I actually make one.

In the meantime, here is a shot of the schematic from Kicad:

Changes

• single sided. makes it much easier to fabricate, and cheaper too. (no more alignment issues)
• fatter tracks on power circuits
• component silkscreen included for easier reference.
