#[Resolved] BTIO drops USB connection to AFC-Lite ~1.5 hours into print

As far as I can tell, the board is entirely passive. It would have to be a bad connection somewhere on it

Is that ruling out the connectors on the board as well? I know the USB C cable to the BTIO board is good, I suppose it could be one of the cables from the BTIO to the AFC lite. It looks like the board is sold out from where I got it but I could request a return?

#

I guess I just doubt 3 different usb c to usb c cables would all react the same and it be the cables not the board

Did you try different cables between the btio and the afc lite?

Yes, 4 different USB C to USB C cables from BTIO to AFC-Lite, the one that came with the BTIO kit, I couldn't connect to the AFC-Lite at all with that one. a no name 5ft cable USB C to USB C cable, a 3ft google pixel USB C to USB C cable, and then a 6 inch Amazon USB C to USB C cable. All three of the last cables exhibited the same issue where around an hour and a half to two hours into a print, the connection with the AFC-Lite would be lost causing the print to fail and a klipper shutdown.

Substituted BTIO board for a USB C keystone and had print failure at 2 hour 15 minute mark. Looking at the USB C cable going from the BTIO to the AFC Lite, it looks like it may be unshielded, will attempt again with a cable capable of video transmission that should be shielded.

#

Looking at the error I'm getting in the logs it looks like its getting an EOF error? Research on that brought up a weakened or over the limit PSU. But since I don't have a failure when I go from the printer's pi directly to the AFC lite, I don't think that is the case. Hopefully shielded cable produces good results.

You have the power switch on the afc lite set to "Buck", correct?

correct

Everything should be powered off 24v then. You could try running it through a powered hub before going into your pi just to rule that out anyways.

I still kind of shy away from it being a power issue because pi direct to BT has no problem on a long print. Its currently 3 hours in on a print direct from pi to BT

I agree, a power issue doesn't seem likely, but its not a bad idea to rule it out

#

Okay I'll get a powered hub and try it out

Resolved. Pi was taken off LDO Leviathan 5v supply and put on a 10 amp 5v power supply, BT was taken off plug in hub and put directly on the Pi.
