GAUPS 1.1

The GAUPS 1.1 boards have just arrived. They look good. They’re the same blue and gold colour as the 1.0 boards.

I need to assemble one, take photos for the instructions, test it, and update the instructions. I also need to order parts for them. With some luck, I’ll get the parts before the few remaining 1.0 kits sell out. I already have the longer lead time items, such as the Arduino headers; I just need the capacitors and the screw terminals.

MakerSlide and NEMA 23 Update

MakerSlide

Just spoke to the factory.  I am not happy.  They have not finished cutting our order.  They still have to do the 250 mm lengths and one other length.  They think they’ll be done by noon tomorrow, and they’ll call after that to arrange delivery.

The shipping company have revised their invoice and I have paid it.  They will let me know the delivery date once they go through customs.

MakerSlide and NEMA 23 Update

MakerSlide

I just spoke to the fabricator. They have finished cutting our MakerSlide, so all that’s left is to arrange delivery. But they work short days on Fridays, and the person who can do that has already gone home. So, next week!

NEMA 23 Motors

The ship is in port and they’re unloading the containers. I got an incorrect invoice for customs charges, so I’ve asked them to amend it. That should not cause a delay, though. They expect to deliver the motors to us on Thursday.

GAUPS 1.1

We’re running out of GAUPS shields. I took advantage of this and I updated the design. It is now compatible with the Arduino R3 pinout: it takes power for the digital side from IOREF, not from the 5 V pin. For older Arduinos or shields, there are solder bridges on the back of the board to configure it for either 5 volts or 3.3 volts. The IOREF solder bridge (the default choice) is shorted by a cuttable trace.

The fourth driver can still be used as its own axis, or as a second driver on the Y axis. However, I have replaced the header and the two jumpers with solder bridges, pre-wired for dual-Y operation. To get a separate fourth axis, cut the DY traces and bridge the A pads.The savings from not including a header and a pair of jumpers that 95% of the users don’t need almost exactly offsets the cost of the R3 Arduino headers (four additional pins total).

 

All-in-One Status Update

MakerSlide

I just spoke with the fabricator. MakerSlide is going to be cut next week. Their saw operator was off sick, and they didn’t want to have a less experienced person cut the MakerSlide, because it’s so easy to damage. That’s reasonable, but communication could have been better.

eShapeoko

I will send another batch of invitation emails today or tomorrow. Orders will have a lead time of about three weeks. The current batch is almost exhausted: some orders will be fulfilled from the current batch, some from the next batch. Here’s what we still need for the next batch:

  • MakerSlide: on order, see above, although there’s still some stock for some eShapeoko sizes;
  • Some laser-cut parts, most critically the mid-span supports. Ordered today, normal turnaround about a week (unless they’re very busy);
  • Misumi profiles for the frame, and M3 insertion nuts: ordered today, normal turnaround 5-8 days;
  • Most standard fasteners and some nylon spacers: ordered today, normally delivered next day. (Got shipping notifications for both while writing this post. The nylon spacers took a grand total of 16 minutes from payment to tracking number. Now that’s efficient! It helps, though, that all they have to do is stuff them in a shipping bag — there’s nothing fragile to protect. Still, very impressive for a small company.)
  • Packing the baggies of small parts: we’re already working on this, and expect to finish before the stock of already packed parts runs out.

We’re good on all parts with long lead times, such as belt pulleys, V-wheels, leadscrews, bearings and so on.

NEMA 23 Motors

The good news is that they’re on their way. The bad news is that the ship is scheduled to arrive on 4 March, not mid-February as I was led to believe, and it’ll probably take another week for the local shipping company to unpack the container, load our motors on a truck, and deliver them to us.

I’m emailing the people who bought backordered NEMA 23 motors with the unpleasant news tonight.

MegaRail 80 and MegaRail Z

I’m promised a quote tomorrow! I already have quotes for the dies, and I’ve settled on designs for both.

Sparrow L-100

More on that soon.
