It looks like I will have to remove the base after just completing the wiring and testing the display and motor drivers voltages on the Rumba. I suspect that having completed the wiring it will be difficult if not impossible to drop the base, and the weight of the power supply would tug at all the wires if I did try this. Making the wires longer so that the base could be dropped would not see difficult to do but this would have to be part of the initial design. Not routing the four groups of wires that are in sleeves through a support would also help. Plus not routing wires under the Rumba would help too. Before I redesign the wheel, (maybe with a chocolate block containing all connections) has anyone an alternative approach to after build maintenance that involves removing the base without disconnecting all the wires?
