And one was where 3 should be...

I have set out the remaining components for the first stepper motor driver board. You can see the re-positioned edge electrolytic capacitor.


The two enormous (in comparison) black components on the right are the stand-in resistors, with their leads bent to fit the board's contact pads!
The component in the middle of these two is the high power header connector - you may remember that's the part I ordered in numbers way over the top, because actually you only needed one, which is broken into 4-way parts. The first go caused a 5-way part (!), so after that I tried needle-nose pliers (too wide), and then cutting the plastic with tin-snips. This worked a treat, but I was glad I was wearing eye protection because each cut part fired off, and bounced off 2 or 3 obstacles before disappearing! I would see where it went first and second and then lose it! Took me a while to find it, based on the landing noise it had made!

See the blue header at the bottom? That's the only one I have. Remember there are 3 stepper motors, and therefore 3 driver boards? Somehow I failed to order 3 of these headers!

So for future orders, so far, the list goes:

• 2 more headers, part 110-3949 from Farnell

• 1 more ceramic capacitor, 100 nF, part 165-0887 from Farnell

• and 1 green 1206 2 mm LED, which I might get from Farnell as well, say part number 1226372 at 6p.

I'm not ordering yet - let's see how many other parts need replacing.
So it will be a while before I finish these three stepper motor driver boards.

Joy and distress

Having been informed by Nophead that I had eleven too many headers (I had ordered 12 24-pin connectors, as listed on the Reprap parts lister, when it seems 4-pins were needed, so one 24-pin cut up into short sections would be enough for all three boards!), I emailed Farnell. I explained that it was entirely my error, that I'd ordered 12 and only wanted 1, and asked if I could send the others back unused for a refund. They emailed to say yes, or at least I'd get a credit raised. Very decent of them, considering!
I've put them back in the post now. That was the joy.

Now for the distress. After RS local trade counter failed to find my goods when I was there, and then took half an hour to determine that the missing item, solder paste, wouldn't be available until the 6th August, I thought I'd better ring the trade counter to check it was there before setting off on my sojourn. I rang the number given for the local counter this morning - but the system automatically puts you through to head-office. I explained what I wanted, and the lady said she'd ring the counter for me to check (since there was nothing on their system) ringing me straight back.

Having heard nothing 3 hours later, I rang again. She said she'd been trying, but nobody answered. She'd continue trying.
Another 2 hours passed, I rang again, and got passed to somebody new, who redirected me to the counter - but all I got was holding messages.
When she went off shift, I got passed to the 3rd operator, who tried again.... Anyway, another 2 hours later, she rang me back to say she hadn't managed to talk to anyone yet (it was now 5 pm) and went away (with me on hold) to consider options.
As a private individual without an account BECAUSE I'D ELECTED TO COLLECT (apparently), she couldn't send me another tube of paste out, because their system didn't have my details on it! It would look like a new order - unpaid. So I'd have to pay again online, and then have a credit put on my account afterwards. Humph. So they'd get to keep the money. Don't like that.
The weird thing is that all my details are on one of their systems - I can get to it all when I log in to their ordering website. After going round the houses, and it being 3 weeks since I expected to have the solder paste, and them not being able to tell me where it was/is, I have requested a refund. I should receive a cheque.
Guess I'll be using my Farnell credit to order solder paste....
