Unable to start up

Gost101

Good day,

I just received my brand new duet wifi 2 from e3D yesterday. I went through the getting started guide. Upon hooking up my 3d printer wires and power up, it does not start up the wifi chip and I do not have a panel duo screen as I planned on using the web interface. Can someone help me diagnose whats going on, I'm happy to skype, google duo, etc.

When you say you went through the getting started guide, were you able to use a USB terminal to add your network settings?

Can you post your config.g file please?

It is possible to connect via USB terminal even when the duet is connected to the printer. Ideally through a laptop on battery power to avoid USB ground loops. This can make it a bit easier to troubleshoot until you're able to get the web interface up.

Yes, I used the usb terminal to add my network settings.0_1568004706655_config.g

I'm only able to connect the duet via the usb terminal when no wires are connected. Making this a time consuming process.

I think you should remove M552 S0 ; start wifi since you'll be covered by M552 S1 in the following line.

That might be enough to allow it to work provided you've already added the network SSID and password.

Gost101

I've tried that as well, no luck.

If unable to connect to your wireless network at boot up, try deleting all saved wifi networks withM588 S"*"(That is, using an asterix for the network name), then re-adding it with M587. For example, M587 S"networkname" P"password".

Also ensure that your main firmware and wifi firmware are up to date.

The wifi antenna of the board must not be enclosed in a metal case. Ideally the antenna should protrude or be next to a wifi transparent material like plastic.

If the signal strength is too low it may be difficult for it to establish a connection.

Having a USB terminal available would make troubleshooting much easier.

I cannot connect to the duet WiFi while ANY of the 3D printer cables are connected. Only the USB terminal can be connected in order to status with no other wires (I have tried both connecting the USB terminal while the 3D printer power supply is connected and disconnected while all wires are connected with no luck on establishing either a USB or WiFi connection. I have tried deleting all of the networks on multiple previous attempts. Currently running 2.03, both firmware's are up to date. The entire board is visible to the eye and is not enclosed by anything. I will not put it in a box/case until I can get this to work.

Gost101

All attempts at deleting saved networks were successful at deletion.

So just to confirm, when you had the board out of the printer and connected only to USB terminal you were able to get the wifi module to turn on and connect to the wifi network and get an ip address?

Gost101

Yes, however upon connecting it back to the 3d printer neither the usb terminal or the wifi module work (The blue status light for the wifi module does not status (turn on-solid blue), and the usb is not detected by my PC).

Phaedrux

Do any lights come on when you're connected to the printer PSU?

Are there perhaps any shorts?

Can you try with the endstops disconnected?

Gost101

PSU on = LED VIN (Blue) and LED = +5V (Red), while USB =LED +5V (Red) and the LED to the left of the USb terminal (Red), Both PSU and USB = LED VIN (Blue), LED = +5V (Red), and LED to the left of the USb terminal (Red). No shorts. I've trouble shooted all day. ALL wires have to be disconnected. Is it possible that I have a defective board?

Phaedrux

I'm unable to determine that. Perhaps @dc42 will have some insight.

I can't figure why it would work on the bench, but not work in the printer other than there being a short.

Gost101

lol, this sucks.

@gost101 bit of a pain to test but can you try connecting it step by step. If you get it in you printer but with only USB connected and confirm WiFi works, then connect things one at a time and check.

I agree with @Phaedrux this sounds like something you are plugging in is causing an issue.

Gost101

Cool beans, increased trouble shooting will start tomorrow later today. I will be back sometime tomorrow with the results.

Gost101

There was a short, on the z stop. However now I will begin troubleshooting as to why the motors are not working.

Phaedrux

By default motors won't move until they are homed.
