Hello, I just finished upgrading my TEVO TORNADO to an MKS GEN L Board

Hello,

I just finished upgrading my TEVO TORNADO to an MKS GEN L Board running Marlin 1.1.8. Before this I got the App a short try and it worked so far.
Anyway I´m new to using GCodePrintr…
Right now I´m not longer able to get a working connection from my phone, nor my tablet to the printer. It is realised by the devices finding automatically the baud rate, as well. Anyway there is no functionality after this.
Any help welcome :-]

Thanks for using Gcodeprintr.
It looks to me that the baud rate is not detected correctly. Could you please set the correct baud rate in the preferences and try again ?

@Mathias_Dietz Thanks a lot for your help. I finally got it :hugs:
The MKS GEN L is coming with the UART CH340 and GCodePrint is not accepting the baud rate oft 2500000 set in Marlin by default.
So i aligned the baud rate in Marlin to the APP and it is working as expected…
