Did the EAF step count reach 0 or reach 65535?
The EAF uses a 16 bit value for the step count and will not go beyond that range.
When you lower the step count and reaches 0, it will stop and beep. If you want it to go farther, you will need to change the "current" EAF step count to something larger than zero, for it to continue to move in that direction.
Similarly, if you increase the step count, the EAF will stop at 65535 and issue a beep. To go farther than that, you need to set the "current" step count to something smaller.
