Duet hardware actually makes it into Thomas Salanderer's videos

Great interview. I can't wait to see what Duet 3 has in store. Maestro also sounds like a nice alternative for those who whine about the price of the current Duets.

Vlad

I literally ask Tom last week where his review on Duet was :))) And here we go. Nice!
I was surprised he hasn't reviewed it yet, as I know he had the board in hand for a while already.

Vlad

Oh well, that's not a review unfortunately. But still nice to hear some news. Hoping he will actually review the board. Maybe he didn't review it because Duet3D folks did not offer him a board? Could be a reason.

Vlad

@bot Yeah, but I paid around $120 for Duet, and Maestro is a "budget" version for $130? I am missing something? $:-\$

The Revolve board is supposed to be $109 and looks like it has better features than the Maestro.

Qdeathstar

what are the maestro specs? It almost looks just like the regular duet ethernet, what’s th difference?

Some specs are discussed in the video, or you can wait until next week.

You got a Duet Wifi/Ethernet(2) for 120?

Vlad

@mysta just double checked. It was $160... Well, in my opinion anyone who is already throwing $130 into the board wouldn't mind throwing additional $30 for a slight upgrade and possibility to expand the system in future. $130 is still very expensive. MKS makes good budget boards for $40-$60, even 32bit, if someone wants real budget. Neither $130 nor $160 is any close to budget ptice for this. Just saying

A genuine Einsy Rambo board is $120 on Ultimachine's web site, and it has only 4 stepper drivers, an 8-bit processor and no web interface. So I think $130 is in the right ball park for a high-quality board that comes with support and a warranty. In time I expect the price will come down.

MKS can only sell boards as cheaply as they do by parasitising open source designs, violating the open source license agreements, offering no support and little or no warranty, and selling boards before they have got the design right (as happened with the SBase). We're not like that.

Exactly, keep up the great work.

Is implementing closed loop support in hardware and software by an encoders on your radar for next version of duet?

We've been keeping an eye on developments in this area, with a view to doing an alternative DueX expansion board that would drive BLDC motors instead of stepper motors. The main problem so far is the lack of suitable inexpensive BLDC motors. The cheap ones used in quadcopters have no gearbox and no sensors, which is OK when you only run the motors at high speeds, but no good for 3D printers. When we need is a BLDC motor with built-in commutation sensors (so that we can run the motor at low speeds), a reduction gearbox (because BLDCs are only efficient at high speeds), and that gearbox must either have very low backlash or else we also need an encoder on the output shaft with a resolution of at least 5000 counts/rev.

Looks like the partner company has jumped the gun on the announcement, they have a page up with all the details already. I wont link to it but its not hard to find on google.

dc42

I presume you mean https://store.printm3d.com/products/duet-2-maestro.

The stepper motor current figure isn't quite right: the maximum is 1.6A peak but we may limit it in firmware to a lower value when we've done the thermal tests. The 18A bed heater current rating also has to be confirmed. The 12864 LCD isn't supported in firmware yet, but the hardware interface has been proven.

The news has also reached Reddit.
Do you have any idea of the UK price yet?

WILD9

@dc42 yes that's the one, didn't really want to step on your toes so didn't put the link up.

The board looks looks great though, I was struggling to justify the cost of a Duet WiFi for my lowly CR-10 but this looks perfect, cant wait to see the the rest of the details, price etc.
