PanelDue stop after config error

gabbie

Hi, Multimeter gives +4.92v as read from the cable plugged into the PanelDue. ![alt text] )

Hope the image uploaded. Is it possible that I've damaged the UART or serial output? Is there a way to test the output port? I have a bus pirate somewhere in the house. Or is that overkill?
Thank you.

I'd be inclined to make up a short replacement cable just to test.

Can you also try sending M575 P1 S1 B57600 in the gcode console just in case it hasn't been activated correctly.

What firmware file specifically did you flash?

Thanks Phaedrux for helping me walk through this. I flashed "PanelDueFirmware-3.4.1-7.0i.bin". I will make a new cable up tomorrow and post the results. Kindly, Gabbie.

I have remade the cable. But no sign of life when reconnected to the Duet2. Below is a photo of the 7i working from the USB. Totally baffled at this stage. I have run M575 P1 S1 B57600 from the console but get no response either. Can I try the ribbon cable from CON_LCD? The Duet is a v1.02.

Phaedrux

Yes try the ribbon cable.

I tried the ribbon in CON_LCD but nothing. Alas. Do you think that is the end of the line?

Uodate: I removed the 7i from the case to examine the components for any damage - maybe I shorted it by being clumsy. I noticed slight marks in the circuit board. I rubbed to feel if it was a removable mark, maybe grease.

Reassembled and voila. Workings again.

Quite likely to go again though I think.

Thanks Phaedrux for all your help. Do you have any advice on a repair if it goes again?

Kind regards Gabbie

When and where did you purchase the Paneldue?

Hi Phaedrux, I bought it from E3D on the 2022-05-19.

If you continue to have issues return to this thread and let us know. I'll mark it as solved for now.

Hi Phaedrux,

My 7i PanelDue has stopped functioning again. E3D replied saying to get back to the forum and post again with the issue. Any advice gratefully appreciated. Thanks Gabbie
