Step(per) 1 finished!

I finished the first stepper motor driver board today. My second mega-resistor went better than the first. I am amazed how often I end up needing to use Blu-Tack to hold things in place; it should be named on the parts list under tools!

So here is the front of the board:

and here is the back, with its near-perfect soldering:

I just wish I could test it, but I don't yet have a 12V power supply, nor do I think I can mock one up, as I did for the 5V previously.

I am very grateful to Nophead who has promised me a replacement 100 nF ceramic capacitor and surface-mount green LED, so I should be able to do the reflow work on the other 2 of these boards towards the end of this week.

I'm hoping to read Barney's blogging of his reflow experiences before I do more, to see if I can pick up any tips.
I really appreciate the help and encouragement and practical assistance given freely on the forum and in people's blogs and comments. It's something special.
I have learnt that these boards that have been giving me quite a challenge are now available ready-assembled! Oh no, they're not are they? I could have waited for that had I known it was in the offing.
Oh well, at least at the end, I can say "I made all of that", with some pride (especially if I have a working 3D printer!) because I knew how to do NONE of this 6 months ago! And I couldn't have done it without the RepRap "community" being what it is.
Meanwhile, I can tackle the cabling, or I've still to try out those penny washers on my mechanical build.

  1. Looks good. Mary put the parts in the post this morning so you should get them tomorrow or the day after.
