Stepper motors pulsing when in Easel

All is stable when sitting idle and I am in Chrome but as soon as I log into easel or go to the tab where easel is on the stepper motors do tiny pulses.
Any ideas?

do they pulse just once or continuously?

Continuousl almost like it was seeing noise from somewhere. It did stop after I shut everything down including my laptop and start all over again. I finished my little project with out any jittering. Don’t know what it was but it’s gone for now.
