Try removing the jumper 14 on the control board. I also had issues establishing a connection with my computer and this made it work consistently since. It requires you to open the control box which can be a bit tricky the first time.

I am really brand new to this, This is my first Printer and I dont know if thats a good idea for me lol. I got the Test print to print great but I cant get anything else to print right since , the first thing I tried to print was a wheel to help with bed leveling because those wing nuts are a pain in the ass. Im going to re-level and try again tonight after work.

OK - I agree - don’t start opening boxes (yet). Start at basics.

1. Open Device Manager in W10 - go to start and type in Device Manager (in Control Panel) in search window. Open DM and go to the top drop down menu View and select Show Hidden Devices

2. Ensure you have Ports (COM and LPT) available and dropping down from that USB Serial Device - usually COM3 but not always. Open this up and check the Baud rate

3. Open Cura and under Machine drop-down go to Machine Settings - check the Communication settings match your DM settings - try to connect.

4. If this doesn’t work - real simple - try a shorter and guaranteed known working USB cable - Cura is very picky over its serial connections

Let me know how you get on.

Steve I seem to be having the same problem. I cant even find my printer in the device menu let alone find the Baud rate.
