Kossel - NonaSuomy/PuRe GitHub Wiki
3D Printer we are attempting to build.
A Kossel is a Delta Robot printer, a new design that is now becoming popular in the RepRap community.
A 3D printer is an incredible tool for a maker to have. Many of the UnLab members have expressed a lot of interest in having a printer and also want to take part in the process of building one.
@WessleeT and Shachar Weis are managing the project, but the goal is to have as much people involved as possible. We plan to do much of the building on Thursday open-nights.

‘’’Note:’’’Do not clean out every hole with a drill. ‘’’We will make note on which ones not to drill in this guide.’’’ Some holes are intended to capture the nut beam without requiring a nut.
Kossel Nuts, Bolts, Screws Kit
Nuts - 108 Pieces - M3
Nuts - 3 Pieces - M4
Jam Nuts - 24 Pieces - M3
Nyloc Nuts - 16 Pieces - M3
Washers - 45 Pieces - M3
Fender Washers - 5 Pieces - M3
Socket Head Cap Screws - 61 Pieces - M3 X 8 mm
Socket Head Cap Screws - 12 Pieces - M3 X 10 mm
Socket Head Cap Screws - 6 Pieces - M2.5 X 12 mm
Socket Head Cap Screws - 23 Pieces - M3 X 12 mm
Socket Head Cap Screws - 33 Pieces - M3 X 20 mm
Socket Head Cap Screws - 2 Pieces - M4 X 20 mm
Socket Head Cap Screws - 19 Pieces - M3 X 35 mm
You may notice that it can be significantly easier with captured nut beams by putting the nut on first and then sliding everything on after it is already threaded. ‘’Alternately, we specifically try to use magnetic nuts (and screws) so you can push them around in the beam with a magnet.’’ This process makes the job a heck of alot easier. ‘’’Tip:’’’ Stick a magnet to a small key to slide the nuts in place down the T-Slot groove. Do the nuts furthest from the center first so they don’t magnetize together and cause issues while aligning them. Be mindful of how many hex nuts you put into the T-Slots of the beams. (We had to remove the corner pieces and add hex nuts, as we didn't realize until after.) Specifically for the clip holder pieces on the bottom interior beams.
‘’’Remember:’’’ You need 6 nuts to slide in the T-Slot aluminum extrusion interior bottom upper frame sides. You will need 2 M3 nuts for the clip plate holders in the T-Slot aluminum extrusion top track and 4 nuts in the inside track, 2 on each motor mount piece.
Motor Spindle (Aluminum in our case with set screw) 400px
Spectra Fishing Line 5 Kossels high
(For printed spools only not aluminum)
Nut - M3 - 1 Piece
Socket Head Cap Screw - M3 X 8 mm - 1 Piece
Install 1 M3 nut with an 8 mm M3 screw.
String up spools
Notes:
- Remember to put the Spectre Line through the spool and attach the spool to the motor before mounting to the frame.
- The pictures that we reviewed showed the electrical stepper motor wires facing upwards to the glass build platform. We decided to put all the wires facing the right hand side to prevent melted/soft wires from the heated build platform glass and from scraping on the ground if positioned the opposite way.
Stepper Motor
PLA Frame_Motor.scad printed piece
Socket Head Cap Screw - M3 X 8 mm - 4 Pieces
Nut - M3 - 4 Pieces Motor - 4 pieces of M3 X 8 mm Socket Head Cap Screws will be attached onto the corner pieces of the frame. Hold the motor with the attached spindle and align it to the holes of the corner piece (magnetized nut beams are your friend here)
200px Use 8 nuts to the extrusion using 6 mm screws. Install M3 20 mm button heads screws through the corner pieces.
Prepare, but do not attach to the extrusion, 6 M3 8 mm screws to the frame cheeks. Use 6 M3 20 mm socket head screws with nuts for the top corner pieces.
Install the 608ZZ Bearings into the 3 plastic idlers and connect the 3 m3 40 mm tensioner bolts with a lock nut to the top corner piece. Then put the idler and everything else into the open beam all at the same time.
Install the 3 limit switches on the frame cheeks with m2.5 12 mm socket head screws.
- Note, be especially careful not to drill out holes any more than necessary unless the screw needs a nut. The 6 bearings, for example, do not require a nut but instead are held in by the plastic.
The limit switch screw currently uses a 16 mm m3 screw. The string anchor uses an m12 m3 screw.
The center head uses the same 20 mm m3 screws and up to 2 nuts, 2 washers and 2 jam nuts to adjust.
Prepare each rod end by wrapping it in string before drilling it with a 3.3 mm drill bit. Then tap it with a 4 mm coarse tap. Be especially careful to frequently reverse the tap.
Each carriage rod connector uses 20 mm m3 button cap head screws and up to 2 nuts, 1 jam nut and 1 washer. When you are all done, you will want the spacing between the rods to exactly match at the carriage and on the head. A small adjustment can be made when adjusting the carriage tightness around the beam by tightening the inside or outside screws, however, you may find that you need to play with nuts, washers, jam nuts, etc. to get them to match exactly.
You can hang a beam from the middle of one of the sides to hang the extruder. HB designed an Airtripper mounting bracket which you can download:
https://docs.google.com/file/d/0BwwU9Nx1dsISODVCb1V5X213SEU/edit
The bracket takes 2 8 mm and 2 12 mm m3 button cap screws with fender washers on the airtripper and a nyloc nut to be certain it does not vibrate loose.
The Bowden end, mounting plate and extruder all mount to the head with 2 20 mm m4 screws and 2 m4 nuts.
Lastly, just mount the hotbed and glass with the clips and you are ready to start wiring up the electronics.

Information topic on the Atmel Atmega 1284P http://arduino.cc/forum/index.php?PHPSESSID=845b17bf7201a45f2643cbedbcb4fe99&/topic,80483.465.html
Other Atmega 1284P Bootloader we are not using this one just here for reference https://github.com/maniacbug/mighty-1284p as we are using the bootloader in the GEN7 Git.
Arduino 1.0.4 -> ArduinoISP Sketch works just fine with the 1284P. 1.0 Had an old version of the sketch from Arduino 0.23 which wouldn't compile properly. So ignore any remarks online about it not working if you have the later versions of Arduino 1.0.4+ etc. It is found in the ArduinoIDE under Examples -> ArduinoISP.
I used these directions for wiring up the ArduinoISP to the Atmega 1284P Note: I didn't use Mighty-1284P for this document http://www.gammon.com.au/forum/?id=11637 we used the Gen7 files: https://github.com/Traumflug/Generation_7_Electronics/blob/master/release%20documents/Gen7%20Arduino%20IDE%20Support%202.1.zip We Select Board Gen7 with 1284P and 20MHz Crystal and then under programmer select ArduinoISP then Burn Bootloader. Dump these files into the Arduino folder like so:
Windows: C:/Program Files/Arduino/ or C:/Program Files (x86)/Arduino/
Linux (Ubuntu): /usr/share/arduino/

Marlin Firmware works with GEN7 since the pull requests from SCUBA on the RepRap Forums (Doesn't work with GEN7T means if you are using Toshiba stepper drivers, which we are not were using Pololu Drivers so it works fine for us.) https://github.com/ErikZalm/Marlin
You may find information in the random forums that Marlin doesn't know how to operate properly at 20MHz but this was fixed in branch: https://github.com/ErikZalm/Marlin/pull/408/files
USBTiny Can't burn the bootloader on any microcontroller with >64K memory it loops over itself and then rewrites. Need to use ArduinoISP or Pololu ISP Programmer or Parallel Hack http://forums.reprap.org/read.php?181,198665 http://blog.think3dprint3d.com/2012/04/space-using-1284p-on-sanguinlolu.html http://arduino.cc/en/Tutorial/ArduinoISP https://github.com/rsbohn/ArduinoISP
Brownout issue while using LCD/SD Conclusion: The coil "L1" wasn't siced correctly till GEN7 1.4.1. It should be 10uH instead of 100uH (as mentioned in the datasheets). Traumflug allready corrected it's value in the new GEN7 v1.5. https://github.com/ErikZalm/Marlin/issues/174
Use this to detect fuse settings if you still have the wires hooked up for the ArduinoISP: http://gammon.com.au/Arduino/Atmega_Fuse_Calculator.zip Open the serial monitor in the ArduinoIDE and you should see output like this:

Not sure if this is needed but I did it any ways as it seems the 10uH coil change was supposed to fix this but anyeways... Edit the Board Configuration we got from the Gen7 Git change the fuses like how we have below for the 1284P 20MHz entry at the bottom of the file:
Linux (Ubuntu): /usr/share/android/hardware/Gen7/boards.txt

Now we get this:

Note the Preserve EEPROM through chip erase has been enabled now with that X beside it and Brownout detection at: 2.7V, Marlin firmware apparently needs this.
Test blink sketch upload from Arduino Uno to the 1284P.
Remove the ATMega328p. Connect TX from the arduino to TX of the ATmega1284, and RX from the arduino to RX of Atmega1284. Then connect the reset pins together.
Note: I tried this and it didn't work! I then tried to make a filter with a 10K resistor inline with the RX0 and a 101(100pf) Capacitor to ground which was recommended because the 1284p has a wild RX0 or something which also didn't work.
