Hey Chris, already seen LowRider Dual-Carriage How-to (IDEX) ?
SKR 1.2 was more straight forward to setup thanks to the V1E docs, precompiled firmware, help from this forum, and it’s archive. SKR worked great until I killed my SKR. Personally, my feelings for Octopus haven’t changed.
Reusing SKR 1.2 and utilizing that 6th driver for IDEX extension would be neat.
