I just changed the order for AR4 stepper kit to AR3 stepper kit, bought from Mouser the encoders and connectors, and all should be right. I believe I can live with the bigger encoder right now, the issues with powering these encoders are simple to sort out, and Chris was good to detail them very well in the manual for AR3. And I trust a lot the CUI encoders, I used them a lot in other projects.
