Assembly instructions
1. We’ll begin by cutting off the R1 (R5) 10㏀ resistor on the Arduino CNC V3 Shield to
remove the pullup to 5Vdc as the Wemos R32 is based on 3.3Vdc:

2. The LV8729 drivers can be configured for 32 microsteps by inserting 2 jumpers on
the CNC shield in slot M0 and M2 (also M1 and M3 on some versions). This must be
done for each driver slot that will be used (leave the middle jumer slot empty - Link):
