Hi, try to increase the step/units at 914.285 instead of 114.28
Also verify that your setting are in mm
If you use the 1/8 step for the driver, you should need 1600 steps ( 200 X 8 ) to turn leadscrew one revolution so you should need 914.286 steps to go 1mm.
Just my idea, I'm not an expert.
Jeff, good luck
