====== Host & Slicing Settings ====== These settings are universal, but we recommend using “[[http://www.repetier.com/documentation/repetier-host/|Repetier Host for Windows/Linux/Mac]]” as the host software which also uses the built-in “[[http://slic3r.org/|Slic3r]]” slicing program. You can download {{:bukobot_profiles.zip|starter Slic3r profiles}} here, or make your own. Note that these profiles are pretty conservative, and a well-tuned Bukobot should be able to use them at 150-200% speed. All numbers are usually in metric millimeters (mm) and temperatures are in (c) celsius unless noted. ===== Global Specs / Settings ===== * Compatibility: Reprap 5D / Marlin / Sprinter **(250,000 Baud)** * Nozzle Diameter: 3mm Filament / 0.35mm extrusion hole * Extruders: 1 for all Bukobots except for the Bukobot 8 Duo which has 2 * X & Y Steps using 15 teeth / 3.18 pitch synchromesh cable 55.99/mm * Z Steps for M6 threaded rods: 3200 * Extruder Steps using Tatsu Drive Gear and 13.6:1 ratio stepper motor: 1260/mm * X/Y Travel Speed: 100-200mm/sec (150mm/sec recommended) * X/Y Extruding Speeds: Max about 200mm/sec (tested), (100mm/sec average recommended) * Extruder Retract Speed: 25mm/minute or less (20mm recommended) * Z axis speed: 250mm/minute (4mm/sec) or less (200mm/minute recommended) * Build Volume: 200mm X 200mm X 200mm (8" inches cube) * Center of platform: X=100mm, Y=100mm ===== Repetier-Host Settings ====== Use the following values for the Printer Settings in Repetier-Host. === Connection === * Baudrate = 250000 * Stop Bits, Parity, Transfer Protocol, Receive Cache Size, Use Ping-Pong are left as defaults. === Printer === * Travel Feed Rate = 9000mm/min (==150mm/s) * Z-Axis Feed Rate = 6000mm/min (==100mm/s) * Default Extruder Temp = 185 * Default Heated Bed Temp = 0 * Number of Extruders = 2 for Duo, 1 otherwise. * Select Remove M105 Request from Log. * Park Position X=0, Y=200 for 8" build area models or 150 for 6", Z-Min=50. This moves the head to the left, pushes table to front and raises the head a bit - but choose whatever you like. * Deselect Go to Park Position after Job/Kill (the Slicer end code settings suggested below already do this) * Select Disable Motors after Job/Kill * Other settings are left as default. === Printer Shape === * Printer Type: Classic Printer * XMin = 0, XMax = 275 for Duo or 200 for single extruder 8" model or 150 for 6" model, BedLeft = 0 * YMin = 0, YMax = 200 or 150 (for 8" or 6" model), BedFront = YMax value. * Print Area Width/Depth/Height: 200 for 8" model, 150 for 6" model Note: the XMin and YMin values assume you have adjusted the X & Y endstops so that they trigger when the extruder is level with the corresponding edge of the print area. For a Duo you should be looking at the right-hand extruder for the X endstop adjustment. === Advanced === * Can be left as default. ===== Slicer Settings ====== ==== Recommended G-Codes ==== === START CODE === <code>G28 - homing</code> === END CODES === <code>M104 S0; Turns off heaters G1 X0 Y150; Homes X axis and brings object to the front M84; Disables all motors</code> ==== Recommended Filament Settings ==== Filament: 2.87mm average, range of 2.80mm - 3.00mm will vary with filament color / batch ==== Hot End (Extruder) Temperatures ==== * PLA (Diamond Age / Printbl.com): 185c average, some colors may need more or less up to 200c * PLA (Ultimachine, others): 200c average, some colors may need more or less up to 210c or so. * ABS: Between 210-230c with 220 average for most colors ==== Platform Temperatures ==== * PLA: With Kapton tape or clean glass 60c * PLA: With Blue Masking tape 0c (room temperature) * ABS: With Kapton Tape 110c, if still doesn’t stick well, try up to 120c. ==== Quality Settings ==== //Note: Most settings will depend greatly on the objects being printed but these are recommended as a starting point.// First layer height should always be 0.3mm (for better platform adhesion) * fast printing use 0.3mm * Good quality 0.2mm * High detail: 0.1mm or 0.05mm Raft/Brim: Usually not needed, but may depend on object. Fill: Recommended minimum of **3 solid layers** and **2 perimeters** (shells) for good results. ==== Filament Cooling ==== PLA usually does not need a fan for cooling, but it will help produce better results and faster prints for small parts, bridging and details. * Install a fan duct to add cooling for PLA (like example image) * Use software to slowdown print: * Min layer time: 20 seconds * Minimum Speed: 10mm/sec ABS should not be cooled with a fan, but should use the same settings as PLA to slow down the printing when doing very small areas or parts
