@jay_s_uk Great, thanks

@dc42 Thanks for the prompt reply. I think I'm going to try to replace that module. Will a ESP-12E be compatible? (I see it's a ESP-12F)

Hi all. I have a Duet WiFi 1.01 that has been running well in my core xy printer for a few years. Recently I decided to disasmble that printer and build a large Delta. I had everything setup and with USB power was able to connect to the web interface and change my config.g and check my endstops. Then I decided to turn on the 24V PSU and things went a little haywire.

Long story short I have disconnected everything and with 24V I see the 3v and 5v LEDs on, but the diag light is constant and the wifi module is not turning on. I can connect via prontoface and when I run M122 it says Error Status: 1 but says all stepper motors are OK. I checked the ESP module and I am getting 3.3V there.

I am wondering three things:

• is it all possible that only the WiFi module got fried? I am considering trying to replace that module but don't want to go through the hassle if other components are damaged

• Is there any more diagnostics I can run?

• What may have caused this type of failure?

I am using the Delta smart effector, 24V power, 120v bed heater.

I also tried flashing the wifi firmware but get a communication failure.

Thanks in advance and sorry for the formatting, I am on my phone.

Editing to add: sd card reader is fine too

Great, thanks for the followup. I have a WiFi and 24V power - I look forward to the feature being added.

I saw a post on RepRap forums a few weeks ago about the possibility of adding a feature to RepRapFirmware to keep two z-motors in sync on power off/on. Is there still plans to implement that or has it already been done?

Thanks
