Disengage all motors from rails before doing the motion test. Disregarding this may result in mechanical damage.
Select 1.2. Drive and Encoder Polarities from iCNC Setup.

2. Opening this dialog box opens the positioning loop. Press Y+, Y-, X+, X- buttons to send out speed signals to the drives and check the
actual rotation of the drive pinion wheels. If rotation is incorrect, change the corresponding polarity in the dialog box and check again.
3. After all polarities are correct, click the Drive Polarity OK check box.
4. Next, set the encoder polarity by pressing the Y+ direction for about 2 seconds. If the polarity is incorrect, the software will automati-
cally detect it and change the setting automatically. Repeat for the +X direction. Click OK when completed.
