PowerBot 3D Printer by PowerPlayground

Last crawled date: 3 years ago

This is my own modified version of the D-Bot printer. I have designed / modified a part or two myself, and some other parts are ones I found off of thingiverse. (If I forgot to or miscredited a model, let me know!)
This build comes in at around $750-$800. I wanted to spec this printer to be able to print exotic materials at high accuracy with little to no compromises and maximum reliability.
I have been filming my progress building this 3D Printer on my Youtube channel Power Playground! Check out the 3D Printer VLOG video playlist: https://www.youtube.com/playlist?list=PLMjfntGK5aY5IezSYz-a1cjPudUg71Mld

The changes made from the original D-Bot are as follows:
-Overhauled the carriage system to use 3 wheels per carriage instead of 4. (Easier to tension)
-Replaced the bowden extruder setup with a direct drive e3d Titan extruder setup.
-Beefed up the build platform carriage, added in adjustable bed holders, and implemented Anti Backlash nuts for the Z acme lead screws.
-Upgraded stepper motor drivers and added an LCD / SD card reader.
-Reduced the amount of special hardware needed.
-Some other things I am forgetting at this time. :P
Future Changes:
-Modify H-Bar and Extruder blacking plates to allow room for the aluminum shim / spacer.
-Modify H Bar belt pulley pathways to have the corner chamfered / filet to allow easier installation of GT2 belts
-Change LCD mount
-Make some minor changes to the marlin firmware for the e3d extruder / hotend and the DRV 8825 stepper drivers.
