Anybody wants a stepper motor analyzer?

DeadNewbie

@zapta do you want the gift card first?

This will be so helpfull for me.

zapta

5 units were shipped today to the people below. Should arrive with 1-2 weeks in the US and 2-4 weeks internationally.

For the next people in line for this batch, if you are still interested please send me via IM you shipping info. Otherwise will move to next people.

After this batch I plan to have at least one more batch of 9 (already have parts on order). Not sure if/when will do additional batches to fill the demand, but will help anybody that want to make them, including commercially, which is relatively simple if you are handy with electronics. Could also be a great Kickstarter campaign since the R&D is done and free.

@zapta Are you still selling them? I just read your post and would gladly buy one!

Which e-gift should I choose? There are tons of stuff, I don't really understand what are the differences...

fma

It seems that's only different logos... Am I right?

zapta

@fma, this one should work

Don't worry about the design, just enter the amount and make sure quantity is 1, then add to the cart and pay.

Shortly after you will get an email with a link to download the 'card' to print. That card will have a claim code which is all I need.

They should have a 'no-nonsense' version of their gift card, without all the fluff.

@zapta: When do you need the gift card, now, or just before you ship? It doesn’t matter to me, let me know which you prefer, cheers.

@zapta @beano I'm wondering the same. I am waiting to know the final shipping costs to Canada so I can add a bit extra on top to show my appreciation.

zapta

@bot, @beano I prefer to get the payment around the time I ship, just in case something will go wrong and I will not be able to ship.

As for amounts, now I that have more experience with the shipping rates, so let's round the totals (including shipping) for future payments:

US: $40

Other countries: $45

Arrived already, thanks again man!

I gave it a quick check with the printer on it's side and it works beautifully. I need another cable to use it properly though.

Maybe you guys can help me out. My familiarity with the various connector types is low.

I had some spare stepper cables like this, so I chopped off the white end and terminated with the connectors zapta sent (on the right). Those plug right into my Duet board, and the black connector into the analyzer.

But, I'm left with a very short length of loose cable after unplugging the motor that I need to get out from under the machine. Basically a male version of the connector on the right. Anything easier that in missing?

zapta

@ccs86, the connector on the right is KF2510 4 pins, it's a clone of a Molex connector, KK or something like that.

You can get KF2510 connector on Aliexpress, Amazon and many other places, or you can get the Molex ones from Digikey and similar.

I solder the wires to the male side and use heat shrink to cover the exposed solder points.

beano

@zapta All Good, thanx for that. Will wait for your message.

Perfect, that is exactly what I had in mind. Thanks for the info man!

The small sine wave like pattern on the step chart indicates the circles, and the magnitude represents the radius.

@zapta cant believe you've not linked to this vid on YT.

I'm interested from a learning perspective but currently have no use for it. I'd actually like to know what people will use this for? To test drivers and steppers I assume but to what extent?

If you are still taking orders, I would be interested in one. I was looking at building my own but don't have the necessary tools to make it easy.
