Need Help! Arduino UNO with CNC shield connection with Jedicut

Hello guys,

sorry my english is not really good.
I´m trying to build a cnc cutter. The hardware is pretty much done but I´m having problems with the software. I have the Arduino Uno with the cnc shield V3.
I don´t have any experience with arduino yet.

I have a problem with the connection between jedicut and the arduino controller.
What did I wrong?

I copied the long code from post #199 viewtopic.php?f=6&t=8582&start=190 and uploaded it with the Arduino software on the Arduino controller.
I changed my Jedicut pinout like in code #199 discribed.
After that I created a comport.ini (there was none before) file with the code from post #215.
My Arduino COM port is 4.

Can anybody help me?

Thank you very much
Best wishes Robin
