@Phaedrux said in Duet 2 Wifi power supply requirements:

Instructions unclear. DuetWifi currently sparking in microwave. Please advise.

Full power or defrost?!

@Danal Everything works as intended now!

Thank you so much guys!

That’s all they’re going to display unless your meter can read PWM.

VERY IMPORTANT! Assigning a drive using M584 does not remove its old assignment. Therefore, if you assign a drive that defaults to being an extruder drive, you should also assign the extruder drives explicitly as in the above example. Failure to do so may result in unexpected behaviour.

you are not unassigning the Y from the extruder. this will cause strange behaviour.

Ok website wrangled with... it should display out of stock options correctly now...🤞

@martin1454 said in Duet Wifi - How to Set IP?:

@perseveranze This is normally done on your router you are connected to - Give the MAC address an reserved IP address, since it is the router that designates the IP (but the duet can request to have the correct IP, but might not get it)

I agree, a router IP address reservation is probably simplest.

Any ways, look at M552 https://duet3d.dozuki.com/Wiki/Gcode#Section_M552_Set_IP_address_enable_disable_network_interface

your command would be M552 S1 P192.168.1.xxx

M552 can only be used to set the IP address on Ethernet-enabled boards. On the Duet WiFi it is necessary to allow the IP address to depend on which network you are connected to, because the same IP address may not be appropriate on different networks. So the IP address is set in the M587 command along with the SSID and password.

If the wires come directly out of the stepper motor (no connector on the motor itself) then you can rely on red and blue being one phase, and green and black the other. So put red and blue at one end of the 4-pin connector on the Duet, and green and black on the other. I use the order red-blue-green-black.

If there is a 6-pin connector on the motor and the wires plug into that, then you can't rely on the colours because different motor manufacturers use different pinouts on the connector. So you need to establish which pairs are phases. Here are 2 easy ways:

Use a multimeter. A pair of wires with continuity between them (a few ohms resistance) is a phase. There should also be continuity between the other pair of wires (the other phase).

Spin the shaft with your fingers. Then short 2 of the wires together and spin it again. If the shaft is much harder to spin with those 2 wires shorted, then those 2 wires belong to the same phase.

Yes, the Duet/RepRap is easily configured for open or closed.

However...

I am a very strong believer in Nclosed (and wired in series if there is more than one). This detects failed switches, broken wires, loose connections in so many ways that Nopen does not.

(It is late, I'm tired, and I hope I typed that correctly, not backwards... you get the drift). 🙂

@perseveranze said in Mach4 with Duet on CNC:

I plan to use the Duet with Mach4 to control my CNC machine. Is Duet able to handle Mach4? I really need to know before shelling out for it. If not, what does everyone use for a g-code generator for their CNC?

If you are determined to use Mach4 (shudder, shudder), pick a controller for which M4 has a "Plug In". A "Smoothstepper", or a "TinyG", and old style "BOB" or similar.

At this time, Duet does not have such a plug in. Interfacing M4 and Duet/RepRap will be a "by hand" stitch-together effort. Personally, I'd never consider it. In addition, once Duet is "hidden" behind such an M4 interface, I can't see that it brings any advantage, as vs. one of the above suggestions.

.

Since I put in my editorial "Shudder" above, I suppose I should explain what I mean. M3 was OK for its time, and I used it quite a bit. M4 happened after the M3 author sold the company... it's a pure marketing grab, a new version number with several reduced capabilities from M3 (because the new people don't really understand shop floor operations of CNC). Purely a marketing/money-grab play. In short, M4 sucks.

I would HIGHLY recommend CNCjs and TinyG, instead of Mach4. Even Chilipeppr and TinyG would be a better choice.

P.S. If you go "Smoothstepper" (a good board), go Ethernet. The Ether version is incredibly stable; the USB version is a bit flaky, in particular the USB cable is sensitive to EMI. Yes... I've run a bunch of Mach...
