Is this is with the old-style (i.e. not universal) extruder controller, and a re-build of the firmware from the latest version? It seems to be getting hiccups with temperature measurement. I fixed the code to solve this for the universal PCB, but had no way of testing it for the old circuit. So it may be my fault...

Yup - that one should do.

That looks good. A few comments: Increasing the pad and via diameters to as much as you can get away with without them touching makes drilling a lot easier. If you could make the 4" dimension 100 mm, that would stop you falling just outside a standard metric board. There are some places where the fat high-current tracks go thin suddenly; best to keep them fat if you can. Also, the high-cuby Adrian Bowyer - Developers

Good idea. They're on a standard 2.54 mm pitch, so they'll solder straight into the board, and people who want to use something else can.

Hi Sebastien - The polyethylene glycol has arrived :-) Many thanks.

No - it's better to leave it as it was and to plot it un-mirrored. That way the laser toner is on the side of the OHP sheet that touches the board and you get cleaner edges.

Zach - thanks for the one-sided comms board design. I've made a few hacks: 1. Expanded pads on most things to 0.08"; makes it easier to drill, and we're not running tracks between pads except for the D connector, for which I left the appropriate two smaller. Thanks for pointing out that you can use the module editor from within the PCB design; that makes this sort of thing so easy. 2. Movby Adrian Bowyer - Developers
