If anyone is looking for instructions on how to build this thing, I've created an instructable located here
Status: Almost there! Print quality is 95% of where I want it to be!
The motto of this project used to be: "If i don't have the part, I print it!" However most, if not all of the printed test/fitment parts have been replaced with their store-bought counterparts
I've included a picture of the mother printer with a coin for comparison! The 3Dtje is so tiny and that's so awesome!!
I'm currently working on an instructable, but for now here are some of my notes and updated parts lists for this printer!
Current printer state:
As of 1/16/18
- Printed idler bearings were sticking... Too much PLA dust. Added some silicone oil and cleaned out the gunk. Much better!
- Got it printing at up to 180mm/s! https://youtu.be/rZ99_lRRO6o Absolutely amazing! I plan on trying to increase this speed!
- Most, if not all of the printed test/fitment parts have been replaced with their store-bought counterparts
- Built rod end cap for Y axis (more cosmetic at this point since I'm not using printed/undersized rods)
- Modified extruder housing to accommodate 10mm PTFE tube holder from hotend
- Reprinted extruder in ABS since PLA was melting from the high motor current (need it for the fast speeds)
- Using @Maxint's Stronger Extruder Lever https://www.thingiverse.com/thing:2250966
- Modified hotend mount for simple, accessible, rigid attachment
- First SUCCESSFUL PRINT!!! https://youtu.be/8qmK9RCalM0
- Best quality print as of 1/10/18 https://youtu.be/S9jyhSjKyg0
- Best quality print as of 1/12/18 shown as the black 3D Hubs Marvin with the dime in the pictures
- Cooling fan duct has been added to not only cool the hotend but to cool the extruded filament at the same time. Black marvin was printed with this duct
- Z banding is still present (could also be PID tuned wrong)
- Haven't figured out how to print reliably past 30mm/s Might be a clone hotend issue. (heatbreak too thick or something)
Things To Do:
- Mount power connector (Arrived)
- Mount USB connector
- Install Raspberry Pi Zero (Attachment?)
- Reprint Motor mounts and Z top for tighter Z guide rod tolerances)
- Design X/Z axis decouplers (Z banding is much more subtle, but still present)
- Clean up wires
- Install Endstops
- Design/Build things to hit endstops
- Find a bigger mirror for print bed
- Design a 4020 Blower fan mount for part cooling
Keep a look out for my parts pack when I finish modifying everything I want to! I had some trouble with some of the parts and so I want to make things a little easier for other people!
