Host & Slicing Settings
These settings are universal, but we recommend Repetier Host. Visit 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.
On a Mac, the Slic3r folder will be at
(as of Lion, ~/Library is a hidden folder, so use the “GO > Go to Folder” menu option i the Finder).
On Windows the Slic3r folder should be at
(for Windows 7).

Use the following values for the Printer Settings in Repetier-Host.
Baudrate = 250000
Stop Bits, Parity, Transfer Protocol, Receive Cache Size, Use Ping-Pong are left as defaults.
Printer / Behavior
Travel Feed Rate = 9000mm/min (==150mm/s)
Z-Axis Feed Rate = 6000mm/min (==100mm/s)
Default Extruder Temp = 200
Default Heated Bed Temp = 60
Number of Extruders = 1 for Vanilla / Bukito or 2 for Duo.
Check Remove M105 Request from Log.
Park Position (These settings “Parks” the extruder, but choose whatever you like.
For 8” / 200mm platforms (Bukobots) X=0, Y=200, Z-Min=10
For 6” / 150” (Mini/Bukito) X=0, Y=125, Z-Min=10
Check Go to Park Position after Job/Kill (the Slicer end code settings suggested below already do this)
Check Disable Motors after Job/Kill
Check Disable Heater
Check Disable Motors
Other settings can be left as defaults
Printer Shape / Dimensions
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.
Note: the XMin and YMin values assume you have adjusted the X & Y endstops so that they trigger when the extruder is even 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.
M104 S0; Turns off Extruder heaters
M109 S0; Turns off Heated Bed heaters
G1 X0 Y150; Homes X axis and brings object to the front
M84; Disables all motors
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
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.
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)
Raft/Brim: Usually not needed, but may depend on object.
Fill: Recommended minimum of 3 solid layers and 2 perimeters (shells) for good results.
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.
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
