These iirc:

Duet Wifi and Duet Ethernet can drive those motors easily. Use 24V power. The maximum speed will be limited to around 150mm/sec (see Tony's post), but from what you have said, that's acceptable to you.
Duet Maestro is a little under-powered for those motors. Duet 3 would be overkill unless you need the 6th stepper driver or the expandability.
-
Thanks all. I will look at getting @Fusedeep running of a DUET ethernet (my friends advise against wifi and in my experience I agree). I run at 24v these days as it happens.
Based on the above and the specs it looks like I would not need any additional pop out/daughter boards for @Fusedeep?
I notice there seems to be a need for a thermistor additional board? Obviously I want to make sure I am getting all the parts I need.
Will make the polar machine as i reconfigure @Fusedeep.
BTW, int the online config tool I cannot see a polar option, delta yes, polar no. Did I miss something?
As mentioned the Maestro's will sort my Makergear M2s nicely by the look of it.

ps, the IGUS gantry comes int at 4K with all their specialist proprietary cables, end stops and the like. All gifted by IGUS!

No. You only need daughter boards if you want to use thermocouples or PT100 sensors. The more normal NTC thermistors are supported without any additional hardware.

The online configuration tool is a sort of "get you started" thing. Not every kinematic option is provided for in that tool but you could select some other kinematics to get most of the configuration done for you, then just amend the resultant files to suit. But there are people using Duet with Polar kinematics so I think it is supported.

I am a little confused about the various thermistor options, or not?

What would I need to do a straight swap to a 24v E3D volcano please?

As per my post above - If you choose to use an E3D thermistor with the Volcano, then you don't need any additional hardware. But if you choose to use and E3D PT100 or E3D type k thermocouple with your Volcano, then you'll need a daughter board.

@deckingman Thanks, I posted my last post without seeing your reply.
I'll get moving on this I think, intend to get the screen too, I assume this will enable me to add an STL/OBJ via SD card and run a print independent of a pc?
-
@FuseDeep You can run a print independent of a pc with and without a screen.
The SD card in the duet itself is used to store the gcode.
The screen enables you to operate the printer without needing to use a phone or pc. Of course, a PC is still required to slice the gcode.I have a screen for my printer but rarely use it as I either use a nearby pc or phone to start a print.
-
Of course. Appreciate slicing needs sorting first.
So if I got the wifi duet 2 I could drop an STL onto the onboard SD card (not necessarily the screen SD) and activate the print from a browser on my phone?
Can I pause and change filament via the browser?
Also, Can I connect adhoc to the DUET or do I need a hub in my studio (currently do not use a wifi hub as no landline here).
R
-
@FuseDeep You can either upload code directly from the slicer or upload the file through the web browser. No need to remove the SD card.
You have full control via the web browser. As well as pausing etc, you can home, run macros, send gcode etc. Its very versatile.
For connecting, you can either assign a static ip address and connect to it directly or you can run a router. For ease, I would go the router route so you can connect to it wirelessly. -
Thanks, I have been just saving the sliced file to the SD card via a cable connection then unplugging and selecting the file via a touch screen. Suppose the eqv is to do it via the browser.
A router won't really work will it? Or will it still be a hub just with no ADSL element? I assume.
wifi connections can be, and often are torturous in my experience. that includes ad hoc etc.
-
I use cura to automatically upload and start prints.
A router doesn't require an internet connection to function so you'll be ok there. You're only connecting to something where everything is served locally.
My wifi is ok. I am always using my phone to monitor prints. I also have a wifi camera attached to my printer to allow me to keep an eye on things. -

This may be instructive.

@deckingman yes. brainfart!

Morning all, thanks for your help recently. Have been distracted by a recent major show of 2 of my sculpture pieces (each partially 3dprinted) at Tate Late:
However...now back to Fusedeep!
Regarding the DUET wifi/Ethernet. Not all my laptops have Ethernet ports and am not always going to gave wifi hub.
Can either board just have gcode slotted in via SD card (appreciate both have an SD card firmware file also) . If I understand it correctly, the gcode of a print and firmware settings go in on the same SD card and it fires up. that would seem to be what i need?
If I know that no matter what I can use a screen to start a print via SD card (regardless of wifi/ethernet) then I will probably go wifi (though 2 duet experienced friends advised against it!).
your advice appreciated. Bit conflicted currently but like the simple on card option with screen. Reliable if i am in the middle of a field, and yest, this is very possible.

@FuseDeep Basically everything runs off the SD card. Once a print has started, you can disconnect and even switch off any computers that are attached and the printer will run quite happily. Of course, you won't have any means of monitoring what's going on, nor will you be able to stop or pause a print. So adding something like a panel due might be your best option.
Edit. If you are in the middle of field, you'll need some means of generating electricity or a big 24V battery
-
@FuseDeep from your description i think you have two general options:
-
Add a PanelDue and connect it using the short ribbon cable. then you can use the SD card slot on the panel due to print from. This is better than constantly removing and re-inserting the SD card on the Duet itself as its easier to get to.
-
Set a Duet 2 Wifi up in access point mode. In that mode you can connect to it like a wifi hotspot from a laptop/phone or tablet.
How to setup the access point details:

The changes needed to M552 netwroking command in config.g to start networking as an access point.

Thanks all.
Power, yes. Am looking at 24v battery, solar and other methods. @Fusedeep is designed to travel and be rugged (hence no oily profile rails).
Also, in my experience relying on any data network is always a no no for many many many reasons.
So wifi with the screen is a good option either way, great. Appreciate the information.
Am looking at a full re gantry of the big printer, this will substantially reduce the load on steppers (using openbuild delrin wheels, already in use on the Z guides.)
Looking forward to having it reliable and much less hassle.

In that case you might find something interesting in this post that I made on my blog a few weeks ago https://somei3deas.wordpress.com/2019/10/22/fitting-a-dc-uninterruptible-power-supply-ups-and-separate-5v-supply/
Although strictly speaking the batteries are charged from the mains, there is no reason why they couldn't be charged from solar or any other source. To run totally "off grid" though, you'd need some pretty hefty batteries to handle a heated bed. In the post that I linked too, my bed is mains powered so in the event of a prolonged power outage, it will eventually cool to the point where a part might become unattached. But then at a pinch you could always resort to the old cold bed/painters tape method.......

HI @deckingman
Yes, have been looking at my options for a few years and have a Narrowboat on the Thames the last 7 yrs (where I ran a Makergear M2 for 18 months about 5 yrs back).
Lot's to consider. First off, lighten the gantry and a new control method...I do not use a heated bed so actually only a few amps needed really. 6 to 8 maximum so a decent battery lasts a surprising time. Plus the big LION domestic batteries are quite light and offer 100% capacity compared to lead acid etc.
Will report!
Thanks R
