Azteeg (Panucatt Devices) is in Irvine California, not China, not a clone.
I've found the boards and drivers to be quite well made, but support for hardware and firmware is sketchy at best...your Google-Foo must be black-belt or higher. Seriously.

I will second that. I recently spent some time with the Re-Arm, Azteeg X5 Mini Wifi, and Azteeg X5 GT. They re all great buys but I really like the X5 Mini Wifi. It is incredibly affordable, $110 USD with 4 removable TMC2224 (TMC2208) drivers.

I just finished adding it to Marlin, and best part is it has an onboard 8266 that has a Web UI THAT WORKS WITH MARLIN! I also did a pin configuration for all of them that supports a single stock cable connection the CR-10 stock LCD.

The only shortcoming of the mini wifi is that lack of driver expandability for multi-material. I think they have a new version coming with more drivers that will replace the X5 GT. Also used the re-arm for a few months and that's a great upgrade if you have a ramps board.

I have the Duet Wifi and Duet X5 as well but for my money, I think Panucatt is where its at right now.

I'm curious: is the WiFi upload speed on the X5 Mini WiFi fast enough to be usable for uploading GCode files?]]> dc42 Next Wave Electronics Working Group Tue, 14 Aug 2018 17:30:52 -0400 https://reprap.org/forum/read.php?181,826446,831230#msg-831230 Re: So where are we in 2018? https://reprap.org/forum/read.php?181,826446,831230#msg-831230

If you are looking for a board that integrates a good 32-bit CPU that you could either mount on another board or plug a shield on to, there's no shortage of evaluation boards from the major microcontroller manufacturers. For example, for $37 you can get this [www.digikey.com], a high-end board with an ARM Cortex M7 processor, SD card socket, Ethernet, and lots of I/O pins. RepRapFirmware has already been ported to it.

No need for "high end", the current LPC1114 can handle the load easily. I was more thinking about something like this: [www.olimex.com]. Two CPUs, plenty of Flash and RAM, 21 GPIO pins (current design uses 14, Gen7-AVR used 17), WiFi, Bluetooth, 6 Euros.]]> Traumflug Next Wave Electronics Working Group Sat, 23 Jun 2018 12:23:50 -0400 https://reprap.org/forum/read.php?181,826446,826611#msg-826611 Re: So where are we in 2018? https://reprap.org/forum/read.php?181,826446,826611#msg-826611

I thought about using one of the dual core ESP32 boards as CPU. There's no shortage of variants: [esp32.net]. One core for doing WiFi, the other core for controlling the printer. Cores are said to be independent, so it could work out to have running one of them running timer driven (for steppers), the other one event driven (for the user interface).

But who'd write the firmware? Me certainly not.

The ESP32 is very cheap, but it has a poor ADC and only enough GPIO pins for a fairly basic controller. There is another thread on this forum bty someone who is designing a controller based on ESP32 + a SAMD MCU for expansion.

The only board I see represented here seems to be Gen7, and it too seems to be dead-ish.

Gen7 was declared dead by the community the day it was released and this changed never since then. No idea why this happens, but that's it.

And of course, like every time I read such declarations, I can assure it's alive. One just doesn't hear much about builders, because these builders need no advice on how to get it going, it is fairly well documented and working fine.

Apparently a design needs to be faulty and flawed to be accepted by the RepRap community. RAMPS is the best example for this.]]> Traumflug Next Wave Electronics Working Group Sat, 23 Jun 2018 04:48:26 -0400 https://reprap.org/forum/read.php?181,826446,826578#msg-826578 Re: So where are we in 2018? https://reprap.org/forum/read.php?181,826446,826578#msg-826578

Dust, I suggest you do proper research in future, to save you the embarrassment of being found to have made a false accusation like that one.

In the last week I posted 15 times, according to the Search facility on this forum. I only mentioned Duet in my post this thread (and I mentioned Smoothieboard too), and in posts that were about using Duet or choosing a controller board. These are some of the posts in which I didn't mention Duet.

So the vast majority of my posts this week did not mention Duet (other than in the "full disclosure" section in the small print of my signature). Where a user describes a problem for which the Duet is a good solution, or asks what controller board to use, of course I mention it if it is appropriate.]]> dc42 Next Wave Electronics Working Group Fri, 22 Jun 2018 15:06:10 -0400 https://reprap.org/forum/read.php?181,826446,826513#msg-826513 Re: So where are we in 2018? https://reprap.org/forum/read.php?181,826446,826513#msg-826513

I think the point about Gen7 was that it's possible for users to make their own PCBs. That limited the designer to a processor with a dual-in-line pinout, which meant a severe limitation in the number of I/O pins.

... Arduino really screwed up the Due with their choice of processor...

Not so IMO. The SAM3X8E was a good processor for its time. Where Arduino really screwed up was in taking a processor with support for a high-speed SD card interface and Ethernet, and then making those features impossible to access. The Duet 0.6 and 0.85 used the SAM3X8E too but used those features to good advantage. Those obsolete Duets still beat the hell out of other boards for speed of uploading GCode files to the SD card over Ethernet. But there are better, cheaper processors available now.

But to each their own.

Quite so (although we don't advertise the Duet, it sells itself so well that ramping up production has been a challenge - especially with the recent global shortage of some passive components). Good design, prototyping, documentation, testing for CE certification, and a continuous improvement policy all cost money. Without these, you get flaws in the original design that are never corrected - as with RAMPS.

On the DIY side, lots of separate people or groups doing the research and coding separately on LPC and STM processors, and who knows on what else. Industrious, but no real genuinely community-accepted results and mass use. Nowhere near like RAMPS in its' day.

If you build an Arduino/RAMPS system, you are using a commercial board (Arduino) and commercial stepper driver modules (Pololu or clones) tied together with a board (RAMPS) that is basically just a pile of connectors and three mosfets. That's little different from using a commercial single-board solution such as Duet, because the Duets (and Smoothieboard) are open source just like the Arduino and Pololu modules. Duet is commercial in the sense of being "professionally developed", while an Arduino/RAMPS/Pololu stack is "mostly professionally developed with a small amount community-developed". Guess which bit causes the most trouble?

+Mikie
So where are we? Is there a board being developed that could take over RAMPS' crown, or are we going to be forever stuck with commercial offerings?

If you are hoping that the community will develop a good-quality board to replace Arduino/RAMPS/Pololu, then you need a retired but competent electronics engineer who has enough time and enough interest to design it, firmware engineers willing to support it, and you need to raise a few $1000s to fund prototyping and testing it. If you want it to be cheap, you will still be dependent on Chinese clone companies to manufacture it at low prices, and you will have to accept variable quality and little or no warranty.

I guess I am biased, but IMO the greatest contributions the community can make are by designing new printers and inventing new techniques and features, rather than by designing the basic electronics to control a 3D printer.]]> dc42 Next Wave Electronics Working Group Fri, 22 Jun 2018 13:28:30 -0400 https://reprap.org/forum/read.php?181,826446,826467#msg-826467 Re: So where are we in 2018? https://reprap.org/forum/read.php?181,826446,826467#msg-826467 Dust Next Wave Electronics Working Group Fri, 22 Jun 2018 09:48:20 -0400 https://reprap.org/forum/read.php?181,826446,826464#msg-826464 Re: So where are we in 2018? https://reprap.org/forum/read.php?181,826446,826464#msg-826464 www.dr-henschke.de]]]> VDX Next Wave Electronics Working Group Fri, 22 Jun 2018 09:41:47 -0400 https://reprap.org/forum/read.php?181,826446,826449#msg-826449 Re: So where are we in 2018? https://reprap.org/forum/read.php?181,826446,826449#msg-826449 It list some other boards also...
