BigBox Dual Titan Direct Drive

This is a Dual Titan Extruder system with all printable parts needed to upgrade the BigBox printer to a Dual Titan Extruder. Print Settings Printer: E3D BigBox Rafts: No Supports: No Resolution:.2 Infill: 35% and 100% Notes: I am reprinting this in ABS, it is cheaper than Edge, and I used all of the green, printing Rev 1. I chose 35% for strength, you could probably do less. Using V6 .4 nozzle will give good quality and accuracy. Don't be afraid to use brim to help with warping. First Layer 95% Height 100% Width 30% Speed Print speed - 50mm/s Along with all of the parts here, you will also need this extended nozzle wipe bracket: http://www.thingiverse.com/thing:1641748 Revisions Rev 1 Initial Release Rev 2 Release Notes: I increased X Axis Rod Hole Diameter slightly for an easy fit. I moved the x-belt tensioner to allow for a cable trough for the left extruder. I added a cable trough for the cables of the right extruder. I moved the x-axis end stop location, to accommodate x-belt tensioner move, on x-carriage and x-idler. I removed interlocking feature on rod clamp for x-axis idler and motor mount to assist in assembly, and installation of the x-axis drive assembly. I removed some material on the motor mount to allow for more +y movement. Rev 1 didn't have enough clearance, and would run into the Y-axis motor mount in the rear. I increased x-endstop wire routing size under x-carriage. I increased Titan Extruder height to allow for more range of motion for when using a Volcano Hotend and Regular V6 Hotend together. You may need to use 25mm long adjustment screws in the Titan Carriage. I increased fan shroud opening size near extruders to allow for more airflow. The openings now get increasing wider from front to back to help with more even airflow. Rev 3 Release Notes: The X Carriage cable troughs for extruder wires have been updated to allow for more room. Fix Titan Extruder Carriage model to fit the Titan Extruder. Update: June 16th 2016 @ 2:30am Titan_Dual_X_Carriage_rev4 - I added fillets in cabling pathways. I modified face by endstop to prevent getting stuck. I updated the IR Sensor Mount location to rear of carriage. Update: June 18th 2016 @ 11:08pm Dual_Titan_IR_Sensor_Mount_rev1 - Modified E3D v1.1 sensor mount to fit. Update: June 20th 2016 @ 5:20pm Dual_Titan_Print_Fan_Shroud_rev4 - I rotated nozzles to point to opposite side of nozzles to help with runaway airflow. I added internal flow control to help with directional flow from the nozzles. I increased nozzle width to allow for more air. Update: June 22nd 2016 @ 6:15pm Dual_Titan_X_Carriage_rev6 - Minor change to prevent endstop from getting stuck in closed position. Update: June 24nd 2016 @ 6:33pm Dual_Titan_Print_Fan_Shroud_rev6 - Angled nozzles to direct air downward at nozzle tip. I widened the nozzles slightly and increased height of nozzles to allow for more airflow.
