Can't connect with Anycubic i3 Mega

I want to connect and control my new Anycubic i3 Mega with Repetier Host because I'm doing it with my Prusa i3 Steel as well. But while the printer sends an acoustic connection signal the log tells me that no start signal is detected:
12:17:00.934 : No start signal detected - forcing start
12:17:41.099 : Communication timeout - reset send buffer block

I'm using the printer with its original firmware.

Would be great if anybody could help me.

Kind regards,


  • Transfer protocol autodetect or ascii. Select correct baud rate, which is the typical issue. If you are on linux make sure no other software uses the port, e.g. our server. That does not work.
