eShapeOko Temporarily Out Of Stock

We ran out of eShapeOko kits again!  I began ordering parts for more of them last week.  I’ll make an effort to go big this time, so that we may have them actually in stock, ready to go the day they’re ordered, hopefully by the end of March.

If you placed your order before the 10th of January, it’s part of Batch Three, and we’re packing those now and they’ll go as soon as they’re ready.

If you placed your order before today (the 30th of January), it’s part of Batch Four, and we aim to ship it by early March.

I’ll turn ordering back on tomorrow or the day after (I’ve still got the VAT return to submit, and I’m busy at work too).  Orders placed from then on will ship later in March.

Batch Three Update: Spindle Mounts Arrived

The laser-cut parts arrived last week.  The laser-cut and machined spindle mounts (EM-LTM) have just arrived.  I’ve checked them: they’re good.  We have MakerSlide on hand for about a third of this batch, and Harry Raley has the rest.  He’s going to ship it to us soon, I’ll cut it, and in the boxes it goes!  Everything else is here, and we’ve been working to count and pack the little bits while waiting for the spindle mounts and rail.

I need to get more PCBs for the buildlog.net shield from Reactive Substance!

Batch Two of eShapeOko Kits Shipped

All but one of the second batch of eShapeOko kits have been picked up by the couriers.  I’ll email tracking numbers tonight.  The remaining kit will be picked up tomorrow.  It is a huge relief, as they were many weeks late.

The third batch is nearly sold out, but I’m not sure exactly how sold out it is because my inventory tracking has been sub-par, to say the least.  I reduced the number of kits available in the store (so now they show out of stock) until I can count all the parts and make sure I don’t have any more surprises.  Earlier this week, I was shocked to realize that I did not have enough end plates and motor mount plates to put together the last kit of the second batch.  I immediately knew what went wrong, but it should not have happened in the first place, had I had a better system.  The buyer graciously accepted my apology.

There will be a fourth batch of eShapeOko kits, but the delivery date for that is not certain (likely February).  I never planned to sell them with a month or more of lead time — the idea was to have them in stock — but you guys keep buying them faster than I can put them together.  (And, in hindsight, I’ve been too cautious about ordering large quantities of parts.)

Thank you for making 2012 a better year for the eShapeOko than I hoped for, and Happy New Year!

Buildlog.net Stepper Shield Full Kit

The Arduino stacking connectors have arrived, and, while rummaging through one of my boxes of parts, I also found a small quantity of 8-pin female headers, so I can now make four full kits.  I tested the 8-pin headers and they work very well with the Pololu drivers (tight grip and good electrical contact, unchanged after a few dozen insertions).  I will email the people who already bought the bare PCBs to see whether they may want the parts to go with their boards, and if there are any kits left after that, they’ll go in the store.

eShapeOko Batch Three Update

When the MakerSlide die problems had started, I made the cautious (read: wimpy) decision to wait until the rail was in sight before I ordered the relatively expensive laser-cut parts for this batch.

I began that process last week, when Harry got the rail from the extruder, but with the factory now closed for the year, there will be no parts until some point in January.

Pulleys are still a problem, but we have enough of them on hand for all the orders placed so far and a few more, but not the entire third batch.  Hopefully, SDP will get back to normal and resume manufacturing them soon.  I now have access to a lathe, so I can re-bore pulleys if I can find them with a smaller bore.  Of course, I’d rather not do that, but I’ll do it if I have no other choice — or to save £5 per pulley…

MakerSlide Finally Here

The UK-made MakerSlide arrived today from Harry Raley.  We were supposed to get it last Friday, but the courier, Nightfreight, “could not find the address” to pick it up from Harry.  More than once.  Their excuse?  New driver who doesn’t know the area very well (and apparently can’t read maps, can’t use satnav, can’t ask dispatch for help, and can’t use a mobile phone very well either).  I would have thought Harry was joking, except that the same thing had happened to me before too, with a different courier that shall remain nameless (FedEx, UPS, DHL, ParcelForce, TNT, Hermes all know that number 1 is usually the first house on the left side of the street; the Yodel driver didn’t, twice).

So, while the MakerSlide is indeed awesome, really nice and smooth, looks great anodized, and the bundle of two-metre sticks is a sight to behold, the chance of any of the eShapeOko kits arriving before Christmas is now exactly zero.  I’m cutting the rail today (Friday), and then booking the parcels to be picked up by the couriers, but I don’t think they would even pick them up, let alone deliver them, until after Christmas.

This pains me greatly, not least because I know that several of the orders were intended as gifts, and have been placed with plenty of time to spare, should everything have gone even remotely close to plan.  I can only ask for forgiveness, and hope that you, or your loved one for whom you so thoughtfully chose it as a gift, will find the kit was worth the wait.

Stepper Shield Kits

As you know, we have the buildlog.net stepper shield from Reactive Substance.  We want to sell complete kits too.  We ordered good quality electronic components, but the connectors were a little more difficult to find at reasonable prices.

Arduino Headers

We have everything now except the stacking Arduino connectors (they’re still on their way).   I’m thinking of offering the kits with ordinary male headers (the ones on the right in the image) for now; they work fine, but the proper Arduino shield stacking connectors (left) have the advantage that you can use the sockets to make additional connections (e.g. limit switches), using wires like the one in the image.Male-Male Jumper Wire

Funny story: each board needs four four-way screw terminals (for the motors) and one two-way screw terminal (for the power supply).  In the quantities we ordered, the price breaks worked so that the two-way terminals ended up costing a little more each than the four-way terminals (those were four times as many).  4-Way Screw TerminalsImagine my surprise when I noticed that the four-way terminals were simply two two-way terminals mated together.

Toothed Belt Pulleys Tantalizingly Close

I think I’ve got my mitts on enough toothed pulleys to complete the second and third batch (so that’s all orders already placed so far, plus a few more).  I won’t know for sure until Friday, when they are supposed to be delivered.  That would be great news.  They are all re-bored from 0.188″ (4.78 mm) to 5 mm, courtesy of the very helpful people at Davall Stock Gears.  They found a machinist and solved this problem for me when their supplier, Stock Drive Products, could not.

The re-bored pulleys have imperial set screws (6-32) with 1/16″ hex sockets.  We bought 1/16″ Allen keys to include in each kit, to save you from hunting around for imperial-size tools.

Those with orders in the second batch already know this: I made an embarrassing mistake.  I wrongly thought that we had all the flexible couplers we needed, but, in fact, they had never arrived (lost on their way from Hong Kong, I assume; why I thought they had arrived I have no idea).  When I realized that, we ordered replacements.  They arrived today, and they are the same good quality, so that’s one more problem sorted.

If you’ve followed Harry Raley’s Ulule updates, you know that MakerSlide was scheduled to be delivered to him this afternoon.  As I was typing this, he confirmed that it has indeed arrived and that it is, I quote, “awesome”!

So all looks set for orders in batch two to ship next week.
