Where can I change the Parameters/Speed of the USB Connection, I could not get any connection to the printer.
Are you talking about Cura?
For Cura I cloned the USB Printing plugin to also support the 500.000bd used by Vertex Delta K8800.
Unfortunately there seems no way to attach a zip…
Click on printer settings (upper right corner)
I have not connected my computer to the printer yet so I don’t know if these settings are correct.
The Problem is that the usb to serial did not suppoert 500000baud. Changing this Setting only changes the speed of the programm not the speed of the Vertex Delta
