Flexion Dual Extruder Mount for Tevo Black Widow

thingiverse

This appears to be a guide for setting up a Tevo Black Widow 3D printer with dual extrusion capability. The guide covers firmware setup, wiring, and print settings. **Firmware Setup** The guide assumes the use of the BugFix version of the BLTouch Marlin RC7 firmware. If you don't have a BLTouch probe, you can ignore the probe offset settings. Here are the steps to set up the firmware: 1. Change `MOTHERBOARD` from "BOARD_RAMPS_13" to "BOARD_MKS_13". 2. Change `EXTRUDERS` from "1" to "2". 3. Change `INVERT_E1_DIR` from "false" to "true". 4. Change `TEMP_SENSOR_0` and `TEMP_SENSOR_1` to match the thermistor type used. 5. Change `HEATER_0_MAX_TEMP` and `HEATER_1_MAX_TEMP` to prevent overheating. 6. Set `X_PROBE_OFFSET_FROM_EXTRUDER`, `Y_PROBE_OFFSET_FROM_EXTRUDER`, and `Z_PROBE_OFFSET_FROM_EXTUDER` to the correct values. 7. Set `LEFT_PROBE_BED_POSITION`, `RIGHT_PROBE_BED_POSITION`, `FRONT_PROBE_BED_POSITION`, and `BACK_PROBE_BED_POSITION` to the correct values. **Wiring** The guide mentions connecting all wiring, but it's unclear what specific connections need to be made. **Print Settings** Here are some print settings that worked for the author: * Printer: Tevo Black Widow * Rafts: No * Supports: Yes * Resolution: 0.2 mm * Infill: 25-50% * Notes: The main bracket requires supports, and it's recommended to use a temperature-resistant material like ABS or Taulman Bluprint. **Final Thoughts** The author mentions that E steps may need to be adjusted due to the stock setting being too high. They recommend starting with a value of 200 and adjusting from there.
