Quick upgrade for easy to plug and unplug end effectors/toolheads. Activity/status LED are also moved from the back of the printer to the top and some more voltage regulation to provide additional voltage rails.
While a nice connector adds significant cost it is also a big value add for certain 3D-printer. I think more manefacturer should consider tiny details like this when designing their product.
Strain relief isn’t installed on this tool for reasons …
I’m not sure this would be really helpful for toolchanger 3d printers, from what I’ve seen you normally want to keep them at a set temperature to reduce heatup time. Also things like CAN means there’s no practical limit on the number of heads.
