      I updated my e3d toolchanger to 3.4rc1 and yesterday I successfully installed a lis3dh.

      I was wondering why the recommended wiring in the documentation uses SPI.CS4 and SPI.CS3 and then clumsily explains what to change in case you're already using temp. daughterboards (I mean, it's not too bad, even I got the cable right on first try. I just messed up the initial config because I connected it to the Duex5 and forgot to change the config to SPI.CS8/SPI.CS7).

      It feels like wiring the connection for SPI.CS4/SPI.CS3 is needlessly fighting the pin rearrangement that the temp daughterboards use. If the accelerometer was wired for SPI.CS2/SPI.CS1, wouldn't that cable work both with and without temp. daughterboards, with only a difference in the configuration gcode? Is the SPI.CS4/SPI.CS3 wiring better from an interference point of view?

        @martink that's a good point! I'll suggest that we change it.
