The Chimeric Printrbot Simple Metal: A complete dual extruder upgrade using E3D's Chimera compact dual v6 system

thingiverse

The text appears to be a detailed guide on how to assemble and configure a Printrbot printer with dual extruders, specifically using a Titan extruder and an E3D hotend. The guide covers various topics such as: 1. Powering the Servo: The servo is powered by an ATX power supply, and the user needs to connect the 4-pin connector to the +12V line and ground on the ATX power supply. 2. Attaching the Extrudrboard: The extrudrboard is attached under the chassis using screws, nylon spacers, and nuts. The metal contacts on the underside of the extrudrboard must not touch the metal on the chassis. 3. Calibrating the Second Hot End Temp: The user needs to connect a Ubis thermistor or a 100K ohm resistor across the two terminals of THERM-B on the extruderboard to get accurate temperature readings. 4. Eliminating Oscillations: To eliminate oscillations in hot end temp, the user needs to connect a large wire between one mounting post of the extrudrboard and the printrboard, and also connect one side of the 2nd hot end E3D thermistor directly to one of the THERM-A terminals. 5. Identifying Locations on the Extrudr- and Printrboards: The user can refer to schematics and photos provided in the guide to help identify locations on the extrudrboard and printrboard. 6. Final Adjustments: The user needs to set the correct offset for the extruders, which is precisely 18mm between the two extruder tips. The user also needs to adjust the Y-axis cable guide to keep cables out of the way. The guide also provides some additional information and troubleshooting tips: * If you can't find any other source, you can buy a 4pin to 6 pin power extension from Printrbot. * Use SchusterConcepts Y axis cable guide to keep cables out of the way. * If you use the Titan extruder, be aware that it runs at about 1/5th the rate of the Alu extruder, and adjust the extrusion rate accordingly. Overall, this is a detailed guide on how to assemble and configure a Printrbot printer with dual extruders. It covers various topics such as power supply, attachment of the extrudrboard, calibration of the second hot end temp, elimination of oscillations, and final adjustments. The guide also provides some additional information and troubleshooting tips.
