@fusedeep said in directions wrong and no zero...:
Major problem now, the green led by the wifi model is gone, so no wifi AND my laptop COM ports have literally F'd off.
This is with the USB cable still connected from your computer to the Duet?

yes, no wifi and com ports totaly gone/dead.
Have tried a new terminal, no better.
Literally the entire com port part of my laptop is fried, AND the wifi to the duet is gone, so I cannot contact the board.
There is no reason for the wifi status to change.
This is getting silly now...

YAT won't re install as framework won't fully update. I uninstalled yat and am now using putty, but it is showing the same errors, no com ports.

When trying to communicate with the Duet via the USB cable was the Duet board getting power from another source via the Vin connections?
Was your laptop running of it's batteries or the charger?
Thanks.

@fcwilt yes, board plugged into 24v feed as usual to run printer for testing.

@fcwilt laptop on mains and battery works fine.

I cannot be sure since I don't know the details of your 24 volt power supply and your laptop but it is possible, under certain circumstances, when the Duet is getting power from both sources (the 24 power supply and the USB cable) that damage to the Duet can occur.
I'm not saying this is what has happened but it might have happened.
If your Duet is damaged and you proceed with getting it repaired or replaced you might want to consider using my approach to getting a Duet up and running. I don't use the USB connection, rather I pull the SD card and connect it to my computer via a SD card reader/writer device. Then I create a minimal config.g file on the SD card with just the commands need to get the WiFi up and running. When the config.g file is ready I return the SD card to the Duet and apply power. Once WiFi is up then I can do the rest of the configuration via the DWC editor.

There is the possibility that it has been damaged by a ground loop through the USB connection.
Can you show a photo of the board when connected to just USB so that we can see the lights?
Same for when just connected to VIN.
Close up photos of the board may show if a component has failed as well, such as a regulator.
You can also check with your finger to see if any component gets very hot.For more detailed steps on how to check what is working or not please go through this guide and let us now what you find.

Jesus. I won't be too impressed if this is the case. It's a 150 quid unit!
How is that even possible?
For some reason this set up has been a proper nightmare. Fusedeep was much simpler and that was my first go!
Will look at it and send images.

Well, all power supplied from the same socket block.
Unfortunately I needed to keep the usb plugged in because the wifi kept disappearing.
All cables well rated ref v-/ground.
It's been a really bad experience with duet, after the initial success with fusedeep.
It has also chewed up hours of my time.
Am extremely frustrated and disappointed in all honesty.
-
I understand your frustration and I'm sorry your experience hasn't been smooth.
USB ground loop is a possibility, but I'm not certain.
At any rate, the best we can do now is follow the guide here and see what the status of the board actually is. Either we can recover, or the board has failed and would need to be replaced under warranty.

As per instructions on that page;
disconnected power and usb.
removed all end stop connectors.
plugged in usb.
All lights came on fine and duet wifi appeared on laptop.
Also got usb bell noise.
However; laptop unable to open any com terminal with yat/putty (yat would not reinstall after i removed it to reinstall it in case yat was borked).
However, after unplugging usb, I reconnected the end stops and reconnected usb cable. back to 2 red led and no wifi .
Seems kaput to me. I think it has also fried my laptop com ports too.
I do remember being recommended a 75 gbp duet board for the makergear m2 rebrain a while back, but iirc it has no wifi option?
Is there a cheaper option than the duet 2 for me?
Good lord.

Did you verify the wiring of the endstops and that they were not shorting out the 3.3 volt power?
When you made the USB connection you heard the typical USB connection sound which suggests your USB port is still working.
Just FYI, COM ports over a USB connection are virtual - there is nothing to fry - other than the USB port itself.
The least expensive Duet I know of is the Maestro but I don't know if they are making that anymore.
The next would be the Duet 3 Mini 5+ which is a very nice board.

@fusedeep sounds like the endstops may be wired incorrectly and if you connect them they are shorting the board. If you come from a RAMPS style board, please note this section: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Sensors_endstops and this one from the old wiki which I can't find in the new docs yet: https://duet3d.dozuki.com/Wiki/Wiring_and_hardware_differences_from_RAMPS_etc#Section_Endstop_switch_connectors

@fcwilt the Duet Maestro is not in production anymore. The Duet 3 mini supercedes it and is only marginally more expensive.
-
Endstops have been working fine for 6 years and nothing changed.
They were working fine after I amended the duet config to correct my error.
They are simple microswitches.
Am honestly not sure how they could go wrong?
But obviously there is some issue somewhere.
I think the board is borked.
-
Ah!
Thank you so much!
I followed that and all 3 end stops happy now and board working on wifi!
Plus the z end stop had an led attached and this was obviously upsetting the system! Disconnected it.
Only thing is, z zero not bouncing back to do a slow zero return but will check the config.
Need to sort my wacky fans now!
