we are testing a 3D printer, with Marlin driver.With Repitiert Host at first test we didn't get any connection with 250000 baud rate.From googling around I am confused if 250000 baud can be accepted by Fedora (I think so) Printer works fine in Windows with same baud rate.Are we missing some point??

I've never heard of a 250K baud rate. I have seen 230.4K (230400) and 256K (256000). I suppose it's possible but I don't know if a standard program (e.g. stty) would know how to set those. It's dependent on the crystal frequency being fed to the USART along with the various divisors in the USART's registers.
It may be that the Windows program goes down into the hardware more deeply than standard Linux software does. You could probably do it by writing code that pokes the appropriate registers in the USART but I wouldn't know how to go about it. It's been a while since I did any bit-fiddling at that level. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@alldigital.com - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - Hard work has a future payoff.

tnx Rick foryour reply.
I confirm that speed is 250000 baud and with same speed it works great in Linux if I use Cura.

Great! You're a smarter man than I, Antonio. As I said, that's just an unfamiliar baud rate to me. Glad you got it sorted out. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@alldigital.com - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - Politicians are the opposite of pickpockets because you never see - - them take their hand out of your pocket. - - -- Larry Fine - ----------------------------------------------------------------------

That rings a bell. I think solidoodle ran into the same problem because linux could support 250000, but the mono pretend to be windows stuff didn't know anything about it so repetier host couldn't set that baud rate through the mono layers.
Solidoodle just fixed it by changing the firmware to use a different baud rate.
