Trigger wifi reconnect during long print

dc42

Assuming you are running recent versions of RRF and DuetWiFiServer, the Duet continuously tries to reconnect if it loses the connection.

If for some reason it keeps failing to reconnect, then you could try resetting the wifi module (M552 S-1) followed by restarting it (M552 S1 assuming you run it in client mode). You could do this in a macro, commanded from a PanelDue or from a trigger.

It was updated to latest version end of November or December. It's been much better recently.

Can this be done through USB?

Wifi light is off, not blinking, just off

Yes, you can send those 2 commands via USB.

You may be on 2.04, or one of the 2.05RC releases. Best to update to 2.05 release: https://github.com/dc42/RepRapFirmware/releases/tag/2.05
@dc42 put in a lot of work to resolve the wifi disconnection issues. When you are next able to connect, please can you send M122 and post the response.

Can I run M122 while printing?

@clytle374 Yes, it should be okay to run M122 when printing!

If I'm reading this properly I'm on the latest firmware.

Error status: 12

Referring to Error_codes_and_software_reset_codes this means:

0x04 Output buffer starvation
0x08 Output stack overflow

RRF 2.04 and 2.05 had changes to fix most instances of these. I've referred this thread to @dc42 to have a look at.

My internet in the building with the printer is a special kind of horrible, the main DSL hasn't been much better. I've spent the last 2 days working on the system. Fixed DSL, I think. Ran ethernet to building and removing the cheap wifi booster out here.

I've changed the wifi name and password in the config.g file on the duet. But it's still connecting to the old wifi. How do I get it to change over?
NEVERMIND: That was way harder than it should be.
Thanks
