I did manage to find some information on these drivers. [attachment 92681 lv8729stepperdriverinfo.docx]
I've just got 4 of these, attached two to my corexy x and y axes. set 1/64th microstepping using the jumper settings in the document above (which are correct as it now has 800 steps/mm (0.9 deg motors) and moves 100mm when asked to).
However to move 60mm/s with just x and y in motion will use 96khz step pulses when re-arm is set for around 100khz max. so 1/32 might be more realistic given that I also need to run the extruder and z axis (with grid compensation).
Doing a few tests now.
