How to establish a terminal connection via ttyACM0 to octopus 1.1?


Recommended Posts

Hi dear community,

i'm an bloody noob, first day with my octopus 1.1 and first try to send a command like 'G0 X10 Y10 Z10' to the board from my ubuntu box (Ubuntu 20.04.4 LTS x86_64, Kernel: 5.4.0-124-generic).

what i tried:

$ lsusb | grep STM
Bus 001 Device 018: ID 0483:5740 STMicroelectronics Virtual COM Port

fine, i have connection. So i watched my /dev while disconnecting and reconnecting the usb-cable:

watch ls -C /dev/

and found out that


appears when i connect the cable, fine but

$ setserial -gG /dev/ttyA*
/dev/ttyACM0 uart unknown port 0x0000 irq 0 baud_base 0 spd_normal

does not reveal a suitable baud-rate and

$ minicom /dev/ttyACM0
minicom: Fehler beim Öffnen der Datei »/dev/modem«: Datei oder Verzeichnis nicht gefunden

doesn't find the port at all.

What do i wrong?

Kind regards
