Baud unstable #3

Closed BugsonPL closed 3 years ago

BugsonPL commented 3 years ago

I find the default baud unstable with Flsun highspeed 1.0 board. Looks like you are having the same problem "Timeout during homing" 115200 works for me fine.

If you could confirm it is worth changing.

Hmm that's strange. The default baud rate of 250000 works pretty well on my Highspeed board. Others seem to have no issue with it. It's even recommended in the documentation:

https://www.klipper3d.org/FAQ.html#how-do-i-change-the-serial-baud-rate

Lowering your baud rate may affect the functionality/resolution of Klipper because the Raspberry Pi has to send all the printer instructions via the serial port.

With other boards I also use 250000 but with this one it is not stable. I don't see any problems with performance.

Okay, since only a minority of people have this problem I'll add it to the troubleshooting section of the README.
