Tutorial and files for operating HOUSE3D printer
If you are interested in building this design, please download the CAD files and the technical report Find more information here : https://dvic.devinci.fr/projects/HOUSE3D https://dvic.devinci.fr/bioextruder https://dvic.devinci.fr/projects/materials-3D-printing
For SAFETY reasons, always keep an eye on the printer and do not use it alone (min 2 operators). Do not go inside the printer when it’s powered If any problem occurs, press the emergency switch immediately.
Check the cables connections and switch on
Connect to the wifi : “router”, pwd: “maisons3D” In the terminal of your laptop: “ifconfig”: to find your ip “nmap-sP 192.168.0.0/24”: see the different objects connected to the network, and find the ip of the rasp, the rasp’s IP may change.
Write the ip of the Rasp “ssh pi@192.168.0.___”, id: “pi”, pwd: “printer”, you are now in pi@octopi To get into the configuration file: “nano printer.cfg” [printer.cfg]: the parts of the file that can be modified, as the rotation distance, the microsteps (need to be the same values as the drivers ones), the position max (the axis does not move beyond this value), … If there have been any changes: crtl O - enter - ctrl X - enter
“sudo service klipper status”, to get the status of klipper “sudo service klipper stop”, to stop klipper “sudo service klipper start”, to start klipper “tail -f /tmp/klippy.log”, to get klipper log “tail -f /tmp/printer”, to view the output of the printer
OctoPrint:
To access OctoPrint: enter the IP address of the rasp on your browser to go on the local network: “https://192.168.0.___”, id: “pi”, pwd: “printer0*” Before each demand, it is necessary to go back to the origin, using the “house” button, or the command “G28”, in the terminal. To have only a specific axis go to the origin use the command “G28 X0” (for the x-axis) If any modifications have been done in the configuration’s files, write “FIRMWARE_RESTART” in the Octoprint terminal to take them into account. If there is any error with the firmware, reconnect, and then write “FIRMWARE_RESTART” in the terminal To print an object: Design a part on a CAO software (Solidworks, Fusion, …) and export it as .STL file Slice the design on PrusaSlicer using the slice profile attached Export the .gcode and upload it on OctoPrint Check the cables and connections Check the belts’ tension Home Z axis, press switch manually before hitting the ground Launch Gcode (the printer will only home the X and Y axis when using the provided profile)
When finish using all the system, write “shutdown-now” in the terminal (in pi@octop) before switching the power off, to avoid damaging the Raspberry Pi
