I've been troubling shooting an issue using
2 Z-axis stepper drivers. I have been suspecting that the issues I am having are in Marlin.
From a recommendation I installed Repetier firmware. I am having problems getting it to communicate over the serial port. I have the baud set to 115200 but have tried other rates 250000, 57600. I currently have the baud set to 115200. When I connect in pronterface (printrun) I get
Connecting...
Attempted to write invalid text to console, which could be due to an invalid baudrate
„$ **'Ø/3†…îJ#æ…BwE$

the baudrate is set sit to 115200 in printrun which is the same as the config. I have similar issues at the other baud rates.
If I flash back to Marlin the problems go away. I am able to connect at 250000 baud rate.
I can tell the flashing to repetier worked because of the changes to the lcd screen.
I'm not seeing settings for stop bits or parity in the repiter configuration.
Any ideas on what's causing this?
