Note that a wireless connection will consume one of the two USB ports on the RPi, making it impossible to connect a mouse, keyboard and printer without a usb hub. With the exception of the installation of a VNC viewer on the client and checking the functionality of Repetier Server, all of the following is completed on the RPi. At present, this is written assuming a wireless network having dhcp enabled is available to the RPi to connect to. Some basic knowledge of the network is essential (netmask, gateway IP address, whether dhcp is used, etc.) will be helpful. An internet connection is essential as several different packages will be installed on the RPi. This is a WIP and there will be changes - I'm writing this as I go.ĭo Not proceed without available internet connection Įverything that follows assumes that the RPi will be attached to a network either by wire or wirelessly. The steps for assembling and configuring the print server follow. It eliminates the need for sneaker-netting g-code via micro-SD and even allows for the printer to be wirelessely connected to the network. This allows g-code to be uploaded and queued for printing by any device sharing a network connection with the print server and having a web browser. Additionally, this method requires loading g-code onto a micro-SD card and then inserting the card into the controller.Ī more attractive approach is employing a web enabled print server such as Repetier Server running on the Raspberry Pi, an inexpensive Linux-based computer. The printer as-designed can be made stand-alone with the addition of an LCD screen, SD card reader and buttons or rotary encoder, but this option is presently challenging to implement with the Melzi control board as it has insufficient i/o. A significant hurdle is the requirement of a host computer to operate the printer, which greatly increases power consumption. One goal of MOST is to improve upon the efficiency of RepRap 3-D printers, facilitating powering the printer with solar photovoltaic cells. 1.8 (Optional) Static IP Address for Wireless.1.1 Do Not proceed without available internet connection.#rotate the image by 180 degrees using imagemagick's convert toolĬonvert -rotate "180" /tmp/snapshot.jpg /tmp/snapshot. #send it with sendmail using a static template (except the dynamic base64 $(date +"%d.%m.%Y %T")"ĮRRMSG="Error: Webcam is not online!
