It appears that you have a comprehensive guide on how to set up and configure a 3D printer, specifically the Prusa Original MK3, with various modifications such as BLTouch leveling and PID tuning. Here's a breakdown of the steps and information: **Before Printing** 1. **Leveling and Calibration**: Level the X axis and Z axis (Z offset) as described in the tutorial files. 2. **PID Tuning**: Perform PID tuning to adapt the hotend heating system. 3. **E-Steps Calibration**: Calibrate E-steps if using a different motor than the E3D. **Importing Cura Profiles** 1. Download Prusa Original MK3 Cura profiles from the official website. **Modifying GCodes for BLTouch** 1. **Start GCode**: Add the following script to the "Before Print Job Starts" script in Octoprint: * `G90 ; Absolute positioning` * `M82 ; Set extruder to absolute mode` * `M107 ; Start with the fan off` * `M140 S60 ; Set bed temp to 60 degrees for leveling and do not wait - preheat` * `M190 S60 ; Wait for bed temp to stabilize` * `M104 S160 T0 ; Hotend at 160 degrees - below melting point preheat` * `G28 X0 Y0 ; Move X/Y to min endstops` * `G28 Z0 ; Move Z to min endstops` * `G29 ; Enable Auto Bed Levelling (ABL)` * `M500 ; Save mesh` * `G28 X0 Y0 ; Return X/Y to min endstops until hotend reach new temp` * `M420 S1; Enable BLTouch leveling mesh` 2. **Part GCode**: Add the following script to the part in your slicer: * `G1 Z15.0 F{speed_travel} ;move the platform down 15mm` * `G92 E0 ;zero the extruded length` * `G1 F200 E4 ;extrude 4mm of feed stock` * `G92 E0 ;zero the extruded length again` * `M117 Printing...` * `G5` **End GCode** 1. Add the following script to the end of your print: * `M104 S0 ; turn off extruder` * `M140 S0 ; turn off bed` * `M84 ; disable motors` * `M107` * `G91 ;relative positioning` * `G1 E-1 F300 ;retract the filament a bit before lifting the nozzle` * `to release some of the pressure` * `G1 Z+0.5 E-5 ;X-20 Y-20 F{speed_travel} ;move Z up a bit and retract filament even more` * `G28 X0 ;Y0 ;move X/Y to min endstops so the head is out of the way` * `G1 Y180 F2000` * `M84 ;steppers off` * `G90` * `M300 P300 S4000` **Raspberry Pi with Octoprint Fullscreen Touchscreen** 1. **Hardware Requirements**: Buy a Raspberry Pi 3B+ without power supply and a 5.5V, 2A power module. 2. **Touchscreen**: Buy a 7-inch official touchscreen display from Kubii. 3. **Case**: Buy a Raspberry Pi case with a 7-inch screen from Thingiverse. 4. **Software Requirements**: Download the latest Octoprint image and copy it to a micro SD card. 5. **Setup**: * `sudo apt-get update` * `sudo apt-get upgrade` * `sudo reboot` * `sudo apt-get install xorg` * `sudo apt-get install raspberrypi-ui-mods` * `sudo apt-get install chromium-browser x11-xserver-utils unclutter` * `sudo nano /etc/xdg/lxsession/LXDE-pi/autostart` and add the line `@chromium-browser --start-fullscreen --start-maximized http://youroctoprintIP` * Save with control+X * `sudo raspi-config` and go to Boot options>Desktop CLI>choose desktop auto login The guide provides a comprehensive setup for a 3D printer, including modifications such as BLTouch leveling and PID tuning. It also covers the setup of a Raspberry Pi with Octoprint fullscreen touchscreen display.
