Re: INCONSISTENT STEPPING - WIERD SITUATION

hey Mariss,

good day,i purchased a seperate p.c. power supply to power the drive
and i'm using one of the 5 volt supplies,is this o.k.? there is some
more information that i could lend. i have used the geckos in the 1x
and 2x modes and it didnt help the situation. i have also tried to
change the acceleration rates within master5 and it did have some
effects, but none of them "cured" the problem. there are times when
the motor does move smoothly but it is intermittent and it seems to
do this only after skipping, and growling a bit.its really strange to
me why the motor works flawlwssly in one direction but not the other.
is there a potential for a problem with the nema 42 size triple stack
motor and the drive? and if so is there a way that i can verify that.
i cant thank you enough for your patients and considerations, as i
couldn't have gotten this far without your help.
