The QU BD dual extruder setup arrived last night. Yay!
Everything was very well packaged and organized and I was able to completely assemble both extruders in about 30 minutes while sitting in front of the TV. One of the nuts seems to have a bad set of threads so I couldn't attach them to the mounting plate. It kept jamming on the heater barrel and I was not willing to force it. I will run a tap through it tonight and finish the assembly. My wife and daughter are both sick so I had other priorities last night.
The plate fits on my X-carriage just fine but I am not sure yet whether I can fit both extruders down through the hole in the carriage. If not I will have to assemble it as a single extruder and then design and print a new carriage when it is up and running.
The only component I am waiting for now is the power supply. I can always use the workstation power supply that I bought for my last machine until it arrives but the new one is much smaller and neater. It will make for a much better organized machine if I can combine the power supply and all the electronics into a single case.
