    Anyone else experienced this? Makes a horrible noise.... Guess this is another bottom off job then. must be a better way to make the internals more serviceable..

    I was thinking of some elaborate frame to support the Rumba and PT 100 amps in the same position but mounted from the upper section, then spin the PSU upside down and mount that from the upper section as well. That only leaves the Octopi and its PSU on the base which are easy to disconnect.

    Of course experimentation would be far simpler if it was possible to buy spare sections of the acrylic frame, I guess I could get one cut locally but it's just going to be a pain to source a small quantity of the same material.

    I was thinking along what you said above, mount all stuff on the upper bottom and leave the bottom part clear

    It's worth asking E3D if they are able to supply them. I cracked one of my panels while attempting to drill a hole in it and got in touch with them and was able to buy a replacement.

    I had some crazy idea about trying to mount the Rumba suspended from the upper base by using standoffs to mount the PCB from above and printing some sort of extension pieces, maybe using the cover screw holes, but I haven't had time to go anywhere with it since work and overtime/weekend working has completely eaten all my spare time lately. You could use a similar approach with the Pi and the PT100 amp boards and maybe just invert the PSU. I have a bunch of longish nylon threaded standoffs somewhere that would work a treat...

    Yes exactly that :) I started thinking along the lines of standoffs then got to a sort of printed cradle that uses the holes around the hatch. It's on the list to play with when I have time.

    The only thing stopping me is so far I haven't had to remove the base on mine (that pleasure won't come until I convert it to dual when the new bits are out, or if it breaks before then)

    Tinkering with a cad sketch of this at the moment, a bigger problem will be the psu mount, i will probably need to be integrated in some way with the spool holder brackets.

    Excellent, I've bookmarked those for when I next need to lift the base (number of reasons is growing now)
