4 to 5 microseconds thats like 4000- 5000 just making apples to apples here my best #s without iso cpu (just havent got there yet ) or hyperthreading turned off are 17000 which i thought was pretty good considering, so the question is is there that much to be gained in upgrading the hardware? My drives will allow for up to 200khz inout but there timing is a bit slow at 7500 for pulse dir and 5000 for step lengthand the other (brain fart) The numbers were not supplied just omes that trial and error showed worked regular and consistent with the defined parameters. maybe i can experiment now that i have the luxury of knowing what i have that does wotk
