3D printing with M1 serial connection problem


I can not connect Cura15.04.6 program version with dobot - Cura can not open port. I click connect, then it shows “opening serial port”, then it shows “Closed”.

The same situation is on Windows 7 and windows 10. I tried with original USB to serial driver and updated driver.

Dobot M1 serial number is:DT2119030010.

Please help. I would like to 3D print face masks to protect my wife which is a medical doctor, but I can’t.

Best regards
Igor from Slovenia in lockdown


Please send me a private message email address and I will give you a usable version of cura
