Hello everyone,

the last days I started working with the FabScan.. including the assembling as well as the software installation. I'm right now struggling with connecting to the FabScan Server. I already recognized that this i a common problem but I couldn't find any answer so far during my research. Whenever I try to connect to the server's ip address, the server is currently not running.

Checking the server leads to the following message... saying that it's active...

pi@fabscanpi: $ sudo systemctl status fabscanpi-server

Hi

I am trying to get my fabscan running i am using an uno arduion board and a pi 3 model b board.

I have read lots of info and changed lots of set up but run in the the same problem sever not running, the log file below say it a board rate i have changed it in the pi set up file and the arduion and not change. would like some help to pint me in the right direction.

Since you have mentioned you are using an uno arduion board are you using the fabscanpi hat provided as part of the kit aor are you trying to use an arduino uno R3?  The arduino R3 will require a hat with the function of the ciclop zum board for driving the stepper, switching the lasers and driving the led lighting.  Also the Arduino serial port address is ttyUSB0 and the loading baud rate is 14400.  If you are using the Fabscanpi hat my guess is that the boot loader needs to be reloaded.

For me, flashing the bootloader was the solution. After that, the connection to the fabscan server finally works. 

You can find an instruction here:

There also is a post regarding the bootloader flashing:
