@abitsean see https://docs.duet3d.com/en/User_manual/Machine_configuration/Configuration_IDEX for how to configure it.

Adding a DueX5 board to your Duet WiFi is the easiest approach to getting another stepper driver, although not the cheapest.

For anyone looking to build an IDEX machine now, the Duet 3 Mini + 2-driver expansion board (total 7 stepper drivers) or Duet 3 MB6HC (6 stepper drivers) would be more economical than Duet 2 + DueX5.

@abitsean from what I can tell, the CAN version of the Hermit Crab only does CAN up to the tool holder, and it's then the same as a conventional Hermit Crab to connect the tool plate.

In principle you could use a non-CAN Hermit Crab to connect tools to the Duet, either directly, or by using a single Tool Board on the tool holder so that you use CAN up to the tool holder. The caveat (as @rjenkinsgb has pointed out is that disconnecting stepper motors while they are powered is bad for the drivers and may cause them to fail. Therefore it's necessary to be very certain that the driver has been disabled before disconnecting the tool.

It may be that what you have in mind is an automatic tool changer with pogo pins or similar spring contacts to connect power and CAN bus. This would be possible in principle, although precautions would need to be taken to limit the surge current when power is connected. But sadly there is a patent on using CAN + pogo pins on 3D printers, which is now owned by Stratasys.

a) probably best to keep to your own thread rather than re-opening three year old ones.
b) check the new docs site at https://docs.duet3d.com/en/User_manual/Troubleshooting/Duet_wont_respond
