7. Mainboard
Step 1. Fix ANYCUBIC mainboard (B09) to the holder (A14) using 3 pairs of C06 and C14.

Step 2. There are 5 pieces of A4988 (B11) in the package. Prepare 4 pieces (the rest is for
backup) of A4988 with Al cooling fin, as Figure 27 shows. Make sure the Al fin does not
touch the pin on A4988 to avoid any short passing.
*A method to calculate the drive current of A4988: use a multimeter to test the voltage
between the two points on A4988, which is pointed out by two red arrows as shown in Fig.
27; then the current (I) can be calculated by the equation of I=U/0.8. Normally the voltage
ranges from 0.75 to 1V, so the current should be in the range of 0.94~1.25A.
