If the model shows a lower quality than desired, you can decrease the printing speed - turn
the LCD-knob counterclockwise. The minimum usable printing speed is around 20 % of the
nominal speed.
7.2.11 USB cable and Pronterface
We strongly recommend using the LCD panel / SD card while printing on the Original
Prusa i3 MK3S+ - Pronterface doesn’t support all functions of the new firmware (e.g.
filament change while printing).
Keep in mind that when printing from Pronterface, the
computer must be connected to the
printer during the whole printing process
- the computer must be prevented from sleep,
hibernation, or shutting down. Disconnecting the computer during the print ends the printing
without the option to finish the object.
● Connect the printer to the computer with the USB cable.
Pict. 20 - You can find the USB port here
● Choose the connection port in Pronterface (download available with the printer
drivers; see the chapter
): Mac users use
/usbmodem
port, PC
Windows ports are COM1, COM2, etc.; the correct port is displayed in the device
manager, Linux users connect the printer using the virtual serial port. When the
printer is connected, click the
Connect
button. The right column displays the
connection information.
● The next step is loading the model with
Load model
button and choosing the
file_name.gcode
(no special symbols in file name).
● You can control the movement of all printer axes using the control area.
● Next, you can preheat the printer and prepare it for printing. Set the temperatures for
the nozzle (heater) and heatbed (bed) and click
Set
button. The printer starts heating
