A few logs ago I talked about the defined interfaces for a quick connector. The bowden setup needs 8 pins for connection. The direct drive configuration will need 12 pins. I've decided to use industrial screw connectors with a 5 amp rating per phase. You could go larger (10amps) but the connector will be huge and 5 amps are just enough for a 60W cartridge (12V).


The implementation:

I've implemented the Weipu WS20-Series. There are several sellers and the documentation is quite well. The quality seems legitimate.

The costs for 4 Connectors with flange are about 30 USD. The connector itself should be around 5-6 USD for each toolhead. It isn't the cheapest solution but I think it's a proper solution.
