### Remix Of - "Bmg (Prusa/Bear) Extruder Quick Swap HotEnd" https://www.thingiverse.com/thing:3847672 ### Pros (Good Point) - ***With X-tensioner*** - 3DTouch (BLTouch) support (Roughly the same geometry as the stock bracket) - Proven systems in Prusa i3 MK3S - Remove the restrictions by building a carriage from scratch, removing the stock obstructive steel plate - Use a common V6 hot end instead of the stock quirky hot end - Incorporates BMG extruder gear components, including 1/3 reduction gears, resulting in stronger torque and more stable filament feed - Quickly remove the hot end without disassembling the extruder - Improving Parts Cooling Performance with 5015 Blower Fan - Selecting and using a 5015 blower fan can make it quieter than the default 3010 fan - The heatsink fan used a common 4010 fan. Choosing a silent fan can make it quieter. ### Cons (Bad Point) - Uses a plastic carriage instead of the stock steel plate, and therefore is less strong - The weight balance is a little strange because of the forced installation (Leaning forward a bit) ### BOM (Bills of Materials) - V6 Heat Sink https://s.click.aliexpress.com/e/_9822uA - V6 Heat Block https://s.click.aliexpress.com/e/_9v2MxG - V6 Heat Break (I choose 41 bore) https://s.click.aliexpress.com/e/_A55hG6 - V5 Heat Block (Brass pipes only used for diverting the stock thermistor) https://s.click.aliexpress.com/e/_AWt182 - HT-NTC100K (If you can install Marlin from source) - BMG Extruder (Use only the parts inside and This is the cheapest choice) https://s.click.aliexpress.com/e/_9zxfAO - Pancake Stepper (Get if you want the choice for improved weight balance and weight reduction) https://s.click.aliexpress.com/e/_AZXH4K - JST PH 5pin box connector for Pancake Stepper https://s.click.aliexpress.com/e/_97Degw - 3D Touch (KINGROON's genuine firmware for auto-leveling has been tested on its own 3D Touch, but it has not been tested and does not work on the external BLTouch, so it is better to choose KINGROON's) https://s.click.aliexpress.com/e/_9g5JPY - GT2-6mm belt (Need a GT2 belt slightly longer than stock for the X-tensioner) https://s.click.aliexpress.com/e/_9AEZpc - Hex Nuts -- M3 Hex Nuts x 9 - Hexagon socket head cap screw -- M3 * 8mm x 1 -- M3 * 10mm x 2 -- M3 * 16mm x 5 -- M3 * 20mm x 2 -- M3 * 35mm x 2 -- M3 * 40mm x 3 -- M3 * 50mm x 1 - Hexagon socket button head screw -- M3 * 8mm x 1 -- M3 * 12mm x 4 ### Set Axis Steps-per-unit (M92) M92 E840 ### Recommended Extrusion Multiplier Calibration Extrusion multiplier and filament diameter https://guides.bear-lab.com/Guide/Extrusion+multiplier+and+filament+diameter/8?lang=en
