Motor chatter

[Zero Cool]

I am having a hard time getting my motors tuned in. no matter what i do they chatter at low speeds. if i change the tuning so they move faster. they run great. and they will move very fast. but slow. they chatter and stutter and make all kinds of noise.

 Any suggestions??

Sounds like the good old days ? before microstepping. 

I use 1/8th stepping and that is pretty smooth at low speed but with the later controllers 1/16th stepping is not uncommon now and that is really smooth.
Could this be the problem ?

What is the make and model of drives you are using?

My motor controller will allow 1/16th microstepping. I currently have it set for full step. tonight I will re-adjust everything at 1/16th and see if i can get the problems to go away.

 The motors are what came with the machine and I can find no Data on them other than whats on the label Shibaura 55230004 30V 2A/Phase 1.8Deg/Step. would love to find a datasheet if anyone has jedi powers to find such things!
