I finally got my machine running and I'm ALMOST there with the mesh leveling. I can get it to probe 25 points but the resulting map is obviously not right.

Here are my bed.g and config.g files. I copied most of the important bits from the other threads. The result I get is from clicking the bed compensation button in the GUI. I know I'm missing something obvious but I have no idea what it is.

The printer is a wanhao I3 with a 190x200 bed. I think it has something to do with the grid… Also the deviation between points seems awfully high.

Boy that's super discouraging. That's two bad boards in a row. I used both the default config.g and a config provided by another wanhao user that was linked here. I get sane output from M906 so I guess I won the Duet lottery again.

Your diagnosis seems spot on. The drivers are indeed cold. All steppers are completely idle as if they're not even plugged in.

I made a thread a couple days ago regarding the spotty WIFI on my new Duet WIFI… The good news is the WIFI on my replacement works great. The bad news is the steppers don't work at all. With the previous board I was able to jog the printer using Pronterface, but with this board the steppers are completely disabled.

In an attempt to troubleshoot, I upgraded to 1.19 Beta9 and I'm getting an immediate "short to ground" and "over temp" errors with nothing connected to the board. I did not touch any wiring while the board was powered up and the board has been sitting on the box it came in throughout the setup process. Starting to lose hope here. Reading the forums it seems like failures are extremely rare so I can't believe my luck.

I have a multimeter and basic electronics experience so I can try to identify the fault if you tell me where to probe. The output below is with absolutely nothing connected except USB. When I had it wired up I had all lights and temps were working. Additionally, the lights for the x,y,z stops worked on trigger. It's just the steppers that don't do anything. The output with 1.18 said the steppers were in standstill.

EDIT: I have verified that all 6 stepper headers have no continuity on any pin to power ground. I can't see any solder bridges or physical damage to the board. ???

Disconnected.

wow thanks for the quick reply. seawest is the name of my 2.4 Ghz network and my seawest 5G is my 5 Ghz network. Both are off of the same ASUS router that sits about 10 feet away. The names are case sensitive and exactly as they're seen from my iphone. My password is alphanumeric and only contains letters and a number.

The thing that makes me suspicious that the board is bad is the fact that I don't see "Duet WIFI" when the board thinks it's in AP mode when using 1.18. Are there any debug commands I can use to test the functionality of the WIFI module itself? I was able to get the board to connect a handful of times and it seemed tied to loading a new WIFI firmware. However, I have tried reloading firmware several times since then and I haven't been able to re-establish a connection.

I WAS able to connect to the "Duet WIFI" SSID but only once. When that occurred I could see my neighbor's APs as well as my own. I was also able to get into the web interface but as soon as I uncommented "M552 S1" and rebooted I had the same problems all over again and could not reconnect.

I just got a Duet Wifi and I'm having a hell of a time with the WIFI setup. I have tried flashing 1.18 stable as well as 1.19 beta 8. I first attempted upgrades via M997 but eventually tried the erase/reset/reload via samba. I have gotten it to connect once or twice but it seems whenever I edit config.g to uncomment M552 S1 it fails to connect again after reboot. I have fiddled with it quite a bit since then and haven't been able to get it to talk to my router again.

I've noticed a couple things

1. when using 1.18 M552 will say that the board is in AP mode but I can't see it in my list of WIFI networks.
2. when it does this it also says hostname is some bunch of gibberish ascii characters
3. when using 1.19 Beta 8 M587 returns the two remembered networks I have configured in my SetNetwork macro however when I do a M552 S1 I get

M587
SENDING:M587
Remembered networks:
seawest
seawest 5G
M552 S1
SENDING:M552 S1
WiFi reported error: no known networks found

I'm starting to think the board is faulty. Is there anything else I can try? It's almost as if the WIFI module is retaining some kind of garbage. Is there a way to purge everything so I'm starting fresh? SD Card, memory, everything?
