Standard Stepper drivers and closed loop stepper drivers that i am used to using in building cnc equipment are cheaper, and include microstepping.
Which drivers do you intend to use?
Are they external drivers, e.g. like this one?

They are definitely not cheaper than an LV8729 or a TMC2130.

And you don't need a custom design board to use them. OnStep already supports external drivers.
You can still use a MaxSTM or any other OnStep board: just make an adapter board and route the
STEP, DIR and EN pins to the external driver, and it is done!

No new design needed.
