Duet 2 Wifi new install - Ender 3

Excelon

Yes, I read that but remember I cannot get the computer to load the drivers for me to get to that point.

Please expand "Ports - COM & LPT" and check whether the port is there.
The message "Device descriptor request failed" normally means (in my experience) that between them, Windows and a USB hub have got into a mess and in effect disabled that USB port. So I suggest you try another port, or reboot Windows.

Excelon

@dc42 You were correct. That port was having an issue and once I changed USB ports it connected fine and uploaded the Firmware just fine. Now that USB port isn't working no matter what. I restarted Windows and it wont reset it's self. What do I have to do in order to reset the reg values just short of reinstalling Windows?

dc42

@excelon, did you try powering down the PC, also the USB hub if it is an external self-powered one?

I have a Duet Wifi installed and running in an ender-3 here at work.

Wiring is simple enough but dont expect the motor wiring pairs to transpose straight over, you need find the base coil pairs and wire to the duet. for some reason none of my motors matched up with the duet compared to the standard board

My extruder is a Titan aero but not much different.

I can post my config.g for you if you want.

Its actually not accurate.
If you take ribbon cable on ender, cut off 4 pin connector and wire new plug strait it will work but you might need to reverse direction in config.g. flat ribbon cable goes to duet pins as 1234.

Nope sorry, it actually is accurate, at least on the machine I have I front of me, if you find different then that's great, But you can't suppose to assume that creality wires things up the same all the time. I have Seen three wired differently now.

And i have used duet boards since the 0.6 and wired them all up not releasing the magic smoke once, And im running 8 Duet boards of both wifi and ethernet versions, so I'm quite comfortable with these things.

Excelon

@dc42 Yes, I rebooted the machine and still the same problem. I got it to work by switching USB ports.

I do understand that you are pretty far down the USB path... and it may be hard to convince you to change... but...

I don't believe I've ever plugged USB into any of my Duets. Just edit the files on the card in a PC or Mac enough to get wireless working, and then did everything else via the web interface. The key file & statements for the first wireless connection are:

/sys/config.g

M550 PDanal's BFD ; Set machine name
M551 P ; Set password (for Duet Web interface, not for WiFi network)
M587 S"MySSID" P"myPassWoRD" ; Set SSID and network key password for WiFi network.
M552 S1 ; Enable network

After you get connected the first time, remove the M587 so that you don't have your WiFi password floating around in a file. The Duet will 'remember' it.

.

Doing it that way, you need never connect USB.

@calvinx Maybe they are different in assembly but the boards and the steppers are the same. it would be a huge unnecessary expense to them to change any part of this. All is based on one, same steppers and wiring so there is less confusion and QC issues. I have 4 enders from different times and suppliers and all of them wire the same. Oh, CR10S4 too which is the same, except for the bigger Y motor.
OP will be able to confirm that

Injecting a comment about Ender 3 revisions... I just saw the other day they have started shipping with silicone boots on the hot end instead of tape.

Again if you say so, I can and will only go with what i have physically seen creality doing, the changes i have seen are not to the boards or the motors but to the wiring looms which in the case we are seeing differing looms not following the logical wiring method.

As a side note to admin is there anyway to block seeing certain users on the forum ?

I find it very confusing that the coils are labelled 2B,2A,1A,1B on the Duet Drive outputs when the motor specifications use A, B, not A, not B for the coils. Specifically, 2B and 2A are on one coil while 1A and 1B are on the other. I was reading it for quite a while as 1A and 2A as the same coil, could somebody tell me why you use this nomenclature on the hardware drawing?

It's because that's how Trinamic label the motor outputs on their driver ICs. We intend to change the labels at the next PCB revision.

Hi, I have a new Ender3 to supplement my efforts with my M3D Promega 3D printer so I am familiar with using and configuring the Duet 2 Meistro board. I want to upgrade my Ender 3 with the Duet2 WIFI controller, the Titan Aero hotend extruder, the BT-Touch probe, and the Panel Due 7i. I presently have these components for my upgrade on hand. What I need is a sample config.g file to use as a model to ease the installation pains along with tips on order of install (ie go "cold turkey" and install all at once, Duet first to get it going, etc). What I don't want to bother with is flashing firmware on the original Ender3 controller. On Dec 13, 2018 CalviNx mentioned he could share his config.g file from his Ender3+Duet2-WiFi+Titan Aero system. Anyone have additional tips for configuring all of this using the BT-Touch? I still need to print the Titan Aero mounts so this is an area for finding recommended .stl files. Any assistance is welcomed.

@seahorserider

I use this mount on mine ender3, https://www.thingiverse.com/thing:3279302
I am not by my printer right now or i would send you my config.g.
Mind you I am using a probe so i cannot help with the BL Touch..

SeahorseRider

Here's themount I'm favoring so far for the Ender3+TitanAero+BLTouch: https://www.thingiverse.com/thing:3078853
Any better ones?

SeahorseRider

I can still use a config.g file for this combo upgrade for the Duet3dWIFI+TitanAero+BLTouch Ender3 upgrade. Also, any better order of install over "cold turkey" attempt of install all, then test, giving a working default ENDER3 original configuration? Or, is it better to get the Duet wifi going with the original extruder first before attempting the Aero install?Comments? Recommendations?

Phaedrux

@SeahorseRider I'd probably do it all at once. If you know the mechanical details of the printer you can use the web configurator to get a config file set that should get you the basics. I'm not familiar with the ender 3 specifics off hand, but it's not exotic. This should give you an idea of what sort of details you need to know about the ender 3 to successfully populate the configurator.

Adapting an existing 3d printer to the Duet

SeahorseRider

Thanks, Phaedrux. Can you give me some tipss on how to implement the BLTouch probe in my planned configuration? Specifically, how to set xyz offsets for the probe, when engaged so Duet mesh mapping really knows where the probe is at. This is where a sample config.g file for my planned mod would be useful. Someone else's implementation may only differ by offsets from nozzle to probe tip. Doint the mesh mapping could be set up with macros like the Promega uses on the Duet Maestro.
