Duet Wifi at ERRF event

Thomllama

so gunna bring my printer to the East Coast Rep Rap fest. thing is is how to use it there? guessing their wifi is going to be not so great/overloaded. and how to hook it up to my iPad or Mac Book so I can at least print with it.

posted on the facebook hoping for a simple answer but basically everyone said "get the panel" wish I can't afford and wouldn't get in time anyway.

Why isn't there a much simpler method of accessing the thing? Guessing from what I've seen/done so far the USB is basically useless for this. Only other thing would be a suggestion to get a cheap Wifi router and bring that.. which honestly sounds like a waste of money and a pain in the butt. hopefully there is something I'm missing?

there is a way not done it but you can put the duet into access point mode so it becomes it's own router.

see M589 and M552

@thomllama you could use your smartphone by setting it to tethering mode (android and iphone both support it) and connecting the tablet and duet both to it. I have never tried that, but it should work.

Dougal1957

yeah but setting the duet as the AP and connecting to that is the easiest way set you the ap params with M589 and start it with M552 S2

Job done

At least one of the two solutions should work.

A problem is that the printer could be hacked for fun.

Phone hotspot may expose printer to public internet. Bad.

AP mode should be WPA2. This should be zero risk (assuming you don't give anybody the passwords).

Choice 3 is to find, borrow, or buy a cheap router. Set it as the network provider (with no upstream internet), and let the printer join that network (as well as your phones, tablets, etc, that you wish to use to run the printer). Again, assuming it is set to WPA2, there is no more risk than any home wireless network.

@dougal1957 seems like the best/easiest answer...

searched and found an older post on doing it here in the forums..
Questions as I'm not super tech in this area of things, though far from clueless..

send M589 S(name of spot) P(password) I(IP address)
send M552 S2 restarts and setup in Access Point Mode
Sign in with info from tablet/phone..

think I got it right? Aren't there specifics I need to make an IP address? Know the Password needs to be 8 laters/numbers. anything else I missed?

Dougal1957

As I said I have never had reason to do it but I think I would start with M552 S0 first followed by M589 and then M552 S2
But I think you have it covered as for the IP Address that you give it I would make it as obscure as you can stay away from the common router std's

If it's at all like MRRF, any wifi will be essentially unusable due to the sheer # of devices trying to talk on it. I just shut my wifi off on the duet before going, and loaded it up with files sliced and ready to print, and managed it all from the paneldue. If you don't have a paneldue, you can do it from the serial console.

@kraegar I think your proposal is best, to avoid interrupted prints.

no panel, to pricy for me.. Bard was a bit more than I should have afforded..

how to use/hook up serial? USB? to a computer (Mac, as that is all I use these days)

kraegar

USB from a PC, then send gcode to tell it what to print , etc.

You can run macros from serial, too. I recommend learning the command line for starting a print (M32 file.g), pausing a print (M25), and running some macros (M98) before you go. Create a macro for your homing routine, pre-heat, whatever if needed.

@kraegar yaaaa...Thanks but, that isn't happening.. I got one day. that and monitoring/controlling isn't easy. the access point thing seems the best. needs a password so don't see it being hacked easily or anything.. seems the least issues with the best control. Honestly it almost seems better than the standard going through the router.. direct, no router BS... still displays the same control panel on computer/tablet.. think it's best all around..? less I'm missing something?

I think your best bet is to set up the Duet as an access point, but to have the means (i.e. a PanelDue or laptop/USB) to either reconfigure the Duet AP to a different WiFi channel, or if that fails to command it directly to run prints from the SD card.
