Formbot Raptor V2 BMG Volcano - Modular Design

thingiverse

By incorporating this design into your Raptor V2, you'll enjoy several benefits without needing to modify the firmware; BLTouch stays at its original reference location as in the stock setup. However, you will need to adjust the Z offset. Additionally, you'll experience a loss of 11.5mm in the Y-axis and 8.5mm in the X-axis. You'll also require longer cables for almost every component, including the fan, motor wires, etc. On the other hand, this design provides a rigid extruder base with perfect front and back balance. Furthermore, you'll gain all the advantages of having a BMG extruder, which includes fast and reliable prints as well as the ability to print flexible filaments. The base module is known as the Bridge Plate and it's solid, requiring no modifications. The other two modules are board plate and fanduct plate, both of which can be upgraded. I opted for the insert design, and the F3D file has all pre-set parameters for dimensions such as the insert slot diameter, flange height, motor screw diameter, etc. The Bridge Plate boasts M3 insert slots on five sides. The top side is unfinished, allowing you to add your own components, like a filament detection holder or gear cover. The right side features two insert slots for the fan-duct plate, while the left side has two insert slots for the board plate. The extension stick side has two slots for the BLTouch. The lower back side of the Bridge Plate has three insert slots for carriage connection. It's worth noting that some carriage plates are slightly different, so you may need to rearrange the holes on the design. I've converted three of my raptors and have found this to be true. The Board Plate has four insert slots to carry the PCB board. The Fanduct plate, however, has two insert slots for the fan. While it works fine overall, there's a possibility that in some cases, the end part may touch the heater block. If you're using low-temperature resistance material, the tip might melt. To prevent this issue, you can either redesign the tip or use an e3d volcano silicon sock. To complete this design, you'll need M3 inserts, which are available on Amazon at https://www.amazon.com/gp/product/B0784VYCYY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. Pancake stepper motors will also work, but I used slightly larger ones, which can be found on Amazon at https://www.amazon.com/gp/product/B01LESPDCQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. Keep in mind that the M3 screw lengths will depend on your motor choice.
