Opinions on "FYSETC" ... politely, please.

Sure, I understand, and for proper open source designs buying off of other manufacturers is okay -- if they mark their products according to the license. I don't know if FYSETC does so with their boards (BTT did when I bought a clone board out of curiosity). Just be aware that in the case of Duet control boards, their design assumes high copper content on the PCB to act as passive heatsink. This may not be critical on PanelDue components, but it is one way non-primary manufacturers reduce production cost (and they rarely document how they cut corners).

Why should we be polite when discussing them ? They are very "impolite" putting it mildly.
Their poor behavior as listed above and other nefarious B.S. merits them to earn the honors of the maker community banning and disparaging them - at least as much as the ABS Mafia in the voron community has ex-communicated Slice Engineering for enforcing their legitimately files patents.
FYSETC - low quality junk. Do not recommend.

The op is Canadian!

@ibash Exactly, I was polite and I also said please. You can feel about FYSETC however you please, but please, please be polite when speaking to me. I promise to listen and consider your words in the manner that they are spoken.
Also know that I'm not looking to start a fire here. I honestly didn't know anything about them --- was even a bit miffed that I'm having trouble finding Duet3D product.
Also know that I don't yet have a horse in this race --- I have not bought anything yet (and it shows well on the community when you respond politely).
To answer an above question, I don't know what the unit comes with, but the pictures on the site include this picture of the back of the board (I only snipped part of it). I don't know if this is sufficient for the license.

I find this interesting. What's the general opinions on the other Chinese manufactures making clones/alternatives? Makerbase, btt, mellow fly. I've never used a direct clone but have used a few mellow boards where I wanted to use stepsticks.
-
@zbeeble Well at least they include the silk screen message and don't try to pass it off as an official board. Whether they use quality components and the same amount of copper, it's impossible for us to say. They may work fine. They may not.
It's worse when the cloners don't tell people up front that it's a clone and people have an expectation of support and warranty.
We do our best to provide support for RepRapFirmware to anyone that asks regardless of the board they are using. We do appreciate when people purchase the real deal though.
-
@phaedrux I do appreciate your position. I won't be buying the electronics for the new printer for awhile yet. I'll keep looking. For all this, other than being "in stock" ... they're not all that much cheaper.
-
@zbeeble I'd just wait for an OG Duet, just out of principle. The incredible effort here must be supported.

Right, they even copied the "Esher3D" typo from the original

@zbeeble If you want to email me (Filastruder), I can see what I can do to get you whatever you need at reasonable shipping. Anything to support Duet3D!
-
@elmoret Are you a wholesaler in Canada? I tried looking to see if I could PM you, but you have DnD set. If you gimme your URL, I'll be happy to look there for my next purchase.
-
@zbeeble In the US, Google Filastruder. Can’t turn on DMs everywhere, can’t track them all.

@zbeeble both our Canadian Genuine resellers appear to have the PanelDue 7i in stock

I think clones and alternatives are very different things.
It's a personal ethics choice, but personally I don't buy clones (chinese or otherwise), but I don't see any problem with alternatives. I have a Mellow board running a sand table, but it's completely different to any Duet3D board, though it runs RRF and I've discussed it here.
I note that it is sometimes difficult to work out who 'started it' - I've seen people mounting a spirited attack on cheap 'ebay special' logic analysers claiming them to be clone / rip-off of saleae devices, but my undertsanding is that the cheapies and the (more basic) saleae devices are both copies of published specimen designs from the chip manufacturer. (I do use a cheapie logic analyser, I don't use saleae software with it.)
I don't think Duet3D claims exclusive ownership of RRF firmware, people other than Duet3D employees have contributed to RRF (I assume - I haven't checked the origin of every line of current code), and indeed there are forums here for RRF on other hardware.

In terms of RRF on other boards, @gloomyandy is the dev who has ported RRF to STM32F4 and STM32H7 boards and I support with documentation etc. The Duet3D team are very supporting of the work we have done and we regularly contribute by finding and fixing bugs and supporting users on this forum.
We also work with Mellow in the development of their boards to ensure they work well with RRF, for example they are the only boards that come with ESP32 wifi adapters on board and the only ones that support monitoring of the PSU voltage -
@jay_s_uk Ive had very good luck so far with the few mellow boards I have, with the exception of some issues connecting to USB here and there. I wish sometimes that duet made a board with stepsticks even if it had limited driver support, as I'd rather support duet than a Chinese company.

I am curious why you need this functionality. When I first got into 3D printing I was using a RAMPS 1.4 board and then went to a RADDS board. I burned out 8x DRV8825 over the course of a year and a half of use. I thought that having built in drivers was a bad idea because everyone seemed to blow them. After a ton of research though I learned that most of the time the blow because of excessive heat or mistakes that can be avoided with improved circuit design. I eventually moved to a Duet 2 Wifi board. Since then I have not burned a single stepper driver even doing the same dumb mistakes as I did in the past. I did have one stepper driver die on my Duet 2 Wifi, but that was on a brand new board and Filastruder immediately RMAed the board once it was confirmed to be a bad board. The Duet boards properly sink the heat away from the stepper driver chips and have all of the necessary protection circuits on them to prevent dumb mistakes. Sure there are still ways to burn one out, but it takes serious effort.

@cthulhulabs the couple printers I use stepsticks on are running makerbase servo42c closed loop steppers. They are large deltas and I have found they help with the occasional layer shift issue. I could have wired them to a duet2wifi or whatever but it's just simpler to use the stepstick adapters. Plus I do as much playing with my printers as I do printing, boards and other various hardware move around a lot.
-
In other words you need support for external stepper drivers and not necessarily stepsticks. That is exactly what the MB6XD @chrishamm mentioned is designed for. Stepsticks are frankly a horrible design that became standard in 3D printers because they were cheap not because they were good.
