PowerBot 3D Printer

thingiverse

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!

Thanks to those who contributed at http://www.openbuilds.com/threads/c-bot.726/ 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. Build Guide / VLOG + Change log 3D Printer VLOG Change Log 12/12/16 - Found a rear frame clip for the extruder wiring. 12/23/16 - Improved Z-Endstop Screw Holder and Added a bracket to attach the 40mm fan duct to the titan carriage backing plate. 1/26/17 - Updated the marlin firmware for accurate steps per mm, e3d v6 pid settings and bang-bang bed temp settings for older relays. (Among other changes) 3/7/18 - Updated firmware to be able to be compiled in later versions of the Arduino IDE, (as well as tweaked the Z steps per mm) Switched the 2 motor Z lead screw system to a 3 lead screw belt train system to be used with 60 tooth gt2 pulleys, replaced 2 vwheels with 3x 8mm linear rods. Updated all the endstops, bed PWM / Relay Mount and a few other models I have probably forgotten to list here. Also updated the BOM since I have swapped out a few parts and am using aluminum brackets to hold the frame together now.
