I've been using Simpify3D for many years.
I've just bought a Flashforge Guider IIS and tried to connect the printer to S3D. It has Wi-Fi and LAN, however know that it is only likely to be possible to connect using USB - which I have tried.
I cannot get the control panel to connect to the printer. It shows in the list of ports as Port_#0002.Hub_#0002 which looks odd in itself. When I select this and try the default baud of 115200 it times out with the following info:
Attempting connection at 11121/9/00000000050C...
WARNING: Unable to open device
Error connecting to selected device.
Has anyone managed to connect this printer?
