====== Host & Slicing Settings ======

These settings are universal, but we recommend Repetier Host. Visit [[Software to Install|Software to Install]] page for downoads.

=== Slic3r profiles to get started ===

//Note that these profiles are pretty conservative, and a well-tuned Bukobot should be able to use them at 150-200% speed.//

==== Installing Slic3r Profiles ====
Step #1 - Before trying to add these profiles, you should launch Slic3r and close it so that it will create the folder for its settings.

Step #2 - You should unpack the //printer//, //print// & //filament// folders of the Slic3r profiles into this folder.

<box round orange>**On a Mac**, the Slic3r folder will be at\\ //**~/Library/Application Support/Slic3r**//\\  (as of Lion, ~/Library is a hidden folder, so use the "GO > Go to Folder" menu option i the Finder).</box>

<box round blue>**On Windows** the Slic3r folder should be at\\ //**C:\Users\<username>\AppData\Roaming\Slic3r**//\\ (for Windows 7).</box>

===== Repetier-Host Settings ======

{{  :software:repetierhost-box-trans-500.png?200}}
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 = 75 for Duo or 0 for other models
  * YMin = 0, YMax = 200 or 150 (for 8" or 6" model), BedFront = 0 (Note "BedFront" is //not// the offset of the front of the bed as you might think; it is the Y axis offset when the //hot end// is at the front of the print area. In other words, you should think of co-ordinate motion in terms of the tool head moving in relation to an imaginary stationary object rather than the movement of the platform itself. This is why for the Bukobot design the Y axis minimum position occurs when the bed is at the rear of the printer so that the hot end is at the front of the bed.)
  * 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 (Extruder 2) 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
