has been awhile posting but got the ESS installed, set motor tuning to x and y/a. can hold down arrow keys for x and y and motors run ok but when running demo they are doing the same thing; dragging, growling stopping. Did not help by buying ESS. Changed computers, no change. It doesn't do it at any certain line in gcode. I am very new at this and i'm sure I have missed a setting. Thanks in advance for any help.
