## Questions & Answers

**Q: Which microstepping mode is the firmware using?**
A: 1/16 step

**Q: Does it use a no or a nc emergency stop switch?**
A: Don't buy. Ran for a couple months and it started throwing huge amounts of RF interference and shuts down computer.

**Q: What is the voltage of the 3 pin laser connector?**
A: Supply voltage and 5vp ttl pulse on middle

**Q: will this work with external drivers ?**
A: Depends on what your driving. Laser or Spindle motor then yes. Stepper drivers I believe need the inductive load to help build the driver signal. So its dependent on what your doing.
