Hi,

I have a problem with my printer Tronxy x5s and Octoprint:
My printing stop about 5-10min of process. Octoprint write this error:

Offline (Error: SerialException: 'device reports readiness to read but returned no data (device disconnected or multiple access on port?)' @ comm.py3831)

Octoprint run on Debian 10 on server HP Prolian ML350 G6.
Have you got any idea? I have already tried several solutions ...

What did you already try to solve it?

Yes I try this:
-New USB cable
-Mask pin1 of USB cable
-Print with disconnected LCD and button panel

I print ABS at 250°C and bed at 105°C.
I have custom powersupply for bed in 24v.
My motherboard is at 12v and hotend is activate by mosfet.

Thanks.

I'm pretty sure you're in the wrong place. I don't do any builds for TronXY printers.
