Where is the fountain of knowledge for learning about CNC setups / understanding them

[Palletlad]

Ooh just remembered to ask I saw the TB6600 stepper motor drivers via amazon and ticked them for a purchase later idea, however when looking for a standard BoB (I know so little on them) I found https://www.ebay.co.uk/i/25208589694...4960578&crdt=0 and I kept having this one pop up https://www.newfrog.com/product/elec...waAsFpEALw_wcB everywhere I looked but not many others? I would have thought there would be all sorts of brands, low, medium, high spec etc

I would not go with the drives all on one board for the same price you could have :- https://www.ebay.co.uk/itm/5pcs-CNC-....c100677.m4598

or

3 of these:- https://www.ebay.co.uk/itm/20KHZ-CNC....c100677.m4598

The bob you linked to is OK if you want a cheap one. I have used them a few times
