As I was thinking about replacing the hotends here I talked about getting plugs and sockets to make all cables pluggable to be able to change: hotends on a dual head heads from dual to pro easily. I now ordered the parts and I received them today and just wanted to get out some pics and facts. Pics first: They are quite light, a plug is about 25g, a socket 27g (@Henry feldman can this be considered 'heavy'?). I ordered the plugs/sockets I need to fit on the case and for the dual. Not for a spare pro as I want to start with making all pluggable but staying with the dual head for the moment and only change the hotends to Volcano. My calculations proved that I need 6 PINs per hotend (heater, fan, PT100) 7 PINs for IR sensor and cooling fans 10 PINs for motors and enstop Using the plugs I linked in the other post, which I have now, I use 2 x 7 PINs for the hotends, 1 x 7 PINS for the IR and fans and 1 x 12 PINs for the rest. First I though of another combination but I wanted to be sure to be able to fit the biggest cables, the heater cables, properly because they have the biggest diameter and the 12 PIN seemed to small for those. That's why I went 2 x 7 PINs for the hotends and not 1 x 12 PINs. So I have to fit 4 plugs/sockets for a complete dual head. As you can see the connectors are not huge but pretty tough. They are made for +500 cycles, that should be more than enough and you screw them together. Unfortunately the contacts have to be soldered, not a problem for me, but maybe for someone else. Unfortunately I can't start because the seller forgot to pack the 12 PIN socket.
