A few people have warned that using that cheap board will limit upper performance but I was told you will be able to run at least 50khz per axis with that cheap board connected to a step generator if you need more you need a better breakout board. For my Mesa card it's £100 for the better BOB so I'm happy to use my existing BOB for now and 50khz is actually a lot depending how you set microstepping.
And just to clarify (I have no clue)
If running 1600 microsteps and 10mm pitch screw with the standard 200steps/rev motors.. how fast will 50khz get me? :D
