Duet Wifi limitations - what are your experiences?
-
Looking at picking up on of these to retrofit into an existing printer and add capabilities for extra extruders, wifi, quieter, etc. For those who've been using this board for a while now what have you found are limitations with it? What do you wish was better? Also, did you set yours up with the proprietary LCD or just control your printer over Wifi?

Biggest limitation? My imagination and understanding of the Gcode commands -
Other than that:
Missing stealth chop on the duet wifi, but spready cycle is okay -
12V fans on a 24V setup is only possible with external hardware (duex5 or an regulator)For a small retrofit, I would go for the Duet Maestro, unless the print is complex (multiple extruder, multiple motors for auto leveling Z, etc.)
I use the paneldue, but 90% of my work is done through the web interface.

I found the Duet to be a fairly robust controller, and I'm quite happy with mine for a 3D printer.
So long as your needs fall within the on-board stepper drivers capability, there's little more that I could ask for.
In terms of it being a drop-in upgrade for another printer, about the only real "gotcha" that I found was needing to re-wire my endstops to change the wire order, but it would still work with the hardware. Also with the endstops, most of the RAMPS clones do allow for both a min and a max endstop, though few printers that I've seen use it, the Duet only has one endstop per axis.
My only disappointment with it was the loss of my 20x4 LCD controller, which was only an issue because I have 3 or 4 of them, and one of the printers that I was/am considering upgrading with the Duet has it more or less built in. The DWC more than makes up for the functionality loss, though the extra SD card slot would be nice.
The biggest downside is that if your printer is working well, and the motors and mechanics are well matched to the power supply and control boards, it can be an expensive upgrade for little change in print quality and speed. If it's worth it for you for the network capabilities, or you want to add functionality that's difficult with your existing electronics, that's a different matter.

Just to clarify, the external hardware is simply to supply the 12V. It can be a $3 buck regulator from eBay or Amazon. A wiring example is here.
My printers (one WiFi, one ethernet) are maybe 10 feet from my computer, so I don't bother with a PanelDue.

Yup - A small buck converter is enough - or if it is a small low power fan like the 30mm E3D, a linear 7812 is also fine.
