//                                  LEADSCREW
//
// Define the type and pitch of leadscrew you have in your lathe.  If you have an
// imperial leadscrew, define LEADSCREW_TPI.  If you have a metric leadscrew,
// define LEADSCREW_HMM (pitch in hundredths of a millimeter).  Do not define
// both.
//================================================================================

// For Imperial leadscrews: pitch in Threads Per Inch (TPI)
#define LEADSCREW_TPI 12

// For metric leadscrews: pitch in hundredths of a millimeter (HMM)
// Example: 200hmm = 2mm
//#define LEADSCREW_HMM 200




//================================================================================
//                                STEPPER/SERVO
//
// Define the number of steps and microsteps for your stepper motor, the pin
// polarity of the driver, and whether to use additional features, like servo
// alarm feedback.
//
// NOTE: If you are using a servo drive with something other than a 1:1 drive
// ratio, you can use the STEPPER_MICROSTEPS to compensate.  For example, if you
// have a servo configured for 1000 steps/revolution and it drives the leadscrew
// through a 3:1 reduction, you can set STEPPER_RESOLUTION to 1000 and
// STEPPER_MICROSTEPS to 3.
//================================================================================

// Steps and microsteps
#define STEPPER_MICROSTEPS 8
#define STEPPER_RESOLUTION 200

// Separate step and microstep settings for feed rates.  Redefine these if your
// lathe has a separate feed drive train with a different ratio.

//================================================================================
//                                 ENCODER
//
// Define the type of encoder you are using on the spindle.  The firmware assumes
// the encoder is turning at a 1:1 ratio with the spindle.
//
// NOTE: the firmware is concerned with the quadrature edge count, which is
// four times the number of pulses.  For example, if you have a 1024 P/R
// encoder, you need to enter 4096 here.
//================================================================================

// Encoder resolution (counts per revolution)

//================================================================================
//                               CALCULATIONS

// touch these settings.

// Use floating-point math for gear ratios
#define USE_FLOATING_POINT




//================================================================================
//                                HARDWARE
//
// Define which hardware you're using:
//
//  1 - LaunchXL F280049C with ELS BoostXL v1
//  2 - LaunchXL F280049C with ELS BoostXL v2
//================================================================================

// See hardware version table above

//================================================================================
//                                FEATURES
//
// Additional features that can be enabled for your configuration.
//================================================================================

// Ignore all key presses when the machine is running.  Normally, only the mode
// and direction keys are ignored.
//#define IGNORE_ALL_KEYS_WHEN_RUNNING




//================================================================================
//                              VALIDATION/TRIP
//
// Validation thresholds and automatic trip behavior.
//================================================================================

// Maximum number of buffered steps
// The ELS can only output steps at approximately 100KHz.  If you ask the ELS to
// output steps faster than this, it will get behind and will stop automatically
// when the buffered step count exceeds this value.
#define MAX_BUFFERED_STEPS 100


//================================================================================
//                               CPU / TIMING
//
// Define the CPU clock, interrupt, and refresh timing.  Most users will not need
// to touch these settings.
//================================================================================

// Stepper state machine cycle time, in microseconds
// Two cycles are required per step
#define STEPPER_CYCLE_US 5
