i3 Sintron with connection Problems (usb)
January 24, 2016 11:05AM
Hi Folks,

Sorry im new in this. My Prusa i3 (from Sintron) is nearly completed, except pronterface wont connect. my baudrate is 115200 on com3 what works with arduino and i can flash the eprom with marlin (1.1.0 R3).
I checked the usb drivers on Win 7 and they are 115200 baud, too.
I just wonder why im able to flsh the eprom but do not get access with pronterface. Looks for an usb problem for me but i cant figure out where to look at.

im pleased for any help or hints.


some more specs:
Sintron Prusa i3
MK8 Extruder
Win 7 Machine

Once you've flashed Marlin, the Baud rate is defined in configuration.h :
// This determines the communication speed of the printer
#define BAUDRATE 250000

Hi Olaf,
Thanks for your help.
At least I found my problem. I had my computer work with com 3, and thought I should put this into marlin too. What was wrong. Now I have port 0 in marlin and it works finally.

So problem solved.
