i am considering buying a closed loop hybrid stepper motor   for my mach3  denford triac mill.
i occasionally loose steps and end up scrapping a part or break tools
ive seen nema34 8nm kits incl driver around £110 .

Does anyone have any experience, good or bad of using these?
i see the alarm feature could activate an e stop, which i guess at least could save parts/tools.

cheers
