I have built a lot of extruders. One solution that is often missing is how to connect a hot end to a filament drive. They are usually created by separate people and the builder needs to decide which ones they want and how to make them work with each other. I found a solution that ends up working with most combinations, and it has some peripheral benefits. I use common picture hanging wire.
- It’s easy.
- It’s cheap.
- It doesn’t need custom plates or outriggers, use what’s available.
- It dissipates heat well, better than bolts.
- It doesn’t require threading or tapping anything.
- It doesn’t rely on any PTFE or PEEK threads for support.
