I was very surprised to be honest just how much better it performed to the others and that's dispite it having a much lower frequency. I mostly put this down to the fact there's less bottle neck from not having an external BOB in between with the signals being much cleaner and more closely controlled.
I am really struggling to figure out which controller to buy, and whether it should have support for gantry squaring or not. My original plan was to run the machine with grbl controller, which does not support separate limit switches on a dual motor axis. So I used a timing belt over a center mounted motor, but the timing belt teared apart quite fast due to the high load (2 x 10 mm pitch ball screw, 30 kg gantry).

Can you help me with these two questions?

1. Which timing belt and pulley size do you use if you run with one big stepper?
2. I plan on buying AM882 drivers. Would you go with CSMIO-IP-M + belt or PLCM-E3 with slave stepper if you were to build a new machine now?
