// If homing is enabled, homing init lock sets Grbl into an alarm state upon power up. This forces
// the user to perform the homing cycle (or override the locks) before doing anything else. This is
// mainly a safety feature to remind the user to home, since position is unknown to Grbl.
#define HOMING_INIT_LOCK // Comment to disable
// Define the homing cycle patterns with bitmasks. The homing cycle first performs a search mode
// to quickly engage the limit switches, followed by a slower locate mode, and finished by a short
// pull-off motion to disengage the limit switches. The following HOMING_CYCLE_x defines are executed
// in order starting with suffix 0 and completes the homing routine for the specified-axes only. If
// an axis is omitted from the defines, it will not home, nor will the system update its position.
// Meaning that this allows for users with non-standard cartesian machines, such as a lathe (x then z,
// with no y), to configure the homing cycle behavior to their needs.
// NOTE: The homing cycle is designed to allow sharing of limit pins, if the axes are not in the same
// cycle, but this requires some pin settings changes in cpu_map.h file. For example, the default homing
// cycle can share the Z limit pin with either X or Y limit pins, since they are on different cycles.
// By sharing a pin, this frees up a precious IO pin for other purposes. In theory, all axes limit pins
// may be reduced to one pin, if all axes are homed with seperate cycles, or vice versa, all three axes
// on separate pin, but homed in one cycle. Also, it should be noted that the function of hard limits
// will not be affected by pin sharing.
// NOTE: Defaults are set for a traditional 3-axis CNC machine. Z-axis first to clear, followed by X & Y.

// Used by variable spindle output only. This forces the PWM output to a minimum duty cycle when enabled.
// The PWM pin will still read 0V when the spindle is disabled. Most users will not need this option, but
// it may be useful in certain scenarios. This minimum PWM settings coincides with the spindle rpm minimum
// setting, like rpm max to max PWM. This is handy if you need a larger voltage difference between 0V disabled
// and the voltage set by the minimum PWM for minimum rpm. This difference is 0.02V per PWM value. So, when
// minimum PWM is at 1, only 0.02 volts separate enabled and disabled. At PWM 5, this would be 0.1V. Keep
// in mind that you will begin to lose PWM resolution with increased minimum PWM values, since you have less
// and less range over the total 255 PWM levels to signal different spindle speeds.
// NOTE: Compute duty cycle at the minimum PWM by this equation: (% duty cycle)=(SPINDLE_PWM_MIN_VALUE/255)*100
// define now lives above. #define SPINDLE_PWM_MIN_VALUE 5 // Default disabled. Uncomment to enable. Must be greater than zero. Integer (1-255).
// By default on a 328p(Uno), Grbl combines the variable spindle PWM and the enable into one pin to help
// preserve I/O pins. For certain setups, these may need to be separate pins. This configure option uses
// the spindle direction pin(D13) as a separate spindle enable pin along with spindle speed PWM on pin D11.
// NOTE: This configure option only works with VARIABLE_SPINDLE enabled and a 328p processor (Uno).
// NOTE: With no direction pin, the spindle clockwise M4 g-code command will be removed. M3 and M5 still work.
// NOTE: BEWARE! The Arduino bootloader toggles the D13 pin when it powers up. If you flash Grbl with
// a programmer (you can use a spare Arduino as "Arduino as ISP". Search the web on how to wire this.),
// this D13 LED toggling should go away. We haven't tested this though. Please report how it goes!

// With this enabled, Grbl sends back an echo of the line it has received, which has been pre-parsed (spaces
// removed, capitalized letters, no comments) and is to be immediately executed by Grbl. Echoes will not be
// sent upon a line buffer overflow, but should for all normal lines sent to Grbl. For example, if a user
// sendss the line 'g1 x1.032 y2.45 (test comment)', Grbl will echo back in the form '[echo: G1X1.032Y2.45]'.
// NOTE: Only use this for debugging purposes!! When echoing, this takes up valuable resources and can effect
// performance. If absolutely needed for normal operation, the serial write buffer should be greatly increased
// to help minimize transmission waiting within the serial write protocol.

// Minimum planner junction speed. Sets the default minimum junction speed the planner plans to at

// limits or angle between neighboring block line move directions. This is useful for machines that can't
// tolerate the tool dwelling for a split second, i.e. 3d printers or laser cutters. If used, this value
// should not be much greater than zero or to the minimum value necessary for the machine to work.
#define MINIMUM_JUNCTION_SPEED 0.0 // (mm/min)
// Sets the minimum feed rate the planner will allow. Any value below it will be set to this minimum
// value. This also ensures that a planned motion always completes and accounts for any floating-point
// round-off errors. Although not recommended, a lower value than 1.0 mm/min will likely work in smaller
// machines, perhaps to 0.1mm/min, but your success may vary based on multiple factors.
#define MINIMUM_FEED_RATE 1.0 // (mm/min)
// Number of arc generation iterations by small angle approximation before exact arc trajectory
// correction with expensive sin() and cos() calcualtions. This parameter maybe decreased if there
// are issues with the accuracy of the arc generations, or increased if arc execution is getting
// bogged down by too many trig calculations.
#define N_ARC_CORRECTION 12 // Integer (1-255)
// The arc G2/3 g-code standard is problematic by definition. Radius-based arcs have horrible numerical
// errors when arc at semi-circles(pi) or full-circles(2*pi). Offset-based arcs are much more accurate
// but still have a problem when arcs are full-circles (2*pi). This define accounts for the floating
// point issues when offset-based arcs are commanded as full circles, but get interpreted as extremely
// small arcs with around machine epsilon (1.2e-7rad) due to numerical round-off and precision issues.
// This define value sets the machine epsilon cutoff to determine if the arc is a full-circle or not.
// NOTE: Be very careful when adjusting this value. It should always be greater than 1.2e-7 but not too
// much greater than this. The default setting should capture most, if not all, full arc error situations.
#define ARC_ANGULAR_TRAVEL_EPSILON 5E-7 // Float (radians)
// Time delay increments performed during a dwell. The default value is set at 50ms, which provides
// a maximum time delay of roughly 55 minutes, more than enough for most any application. Increasing
// this delay will increase the maximum dwell time linearly, but also reduces the responsiveness of
// run-time command executions, like status reports, since these are performed between each dwell
// time step. Also, keep in mind that the Arduino delay timer is not very accurate for long delays.
#define DWELL_TIME_STEP 50 // Integer (1-255) (milliseconds)
// Creates a delay between the direction pin setting and corresponding step pulse by creating
// another interrupt (Timer2 compare) to manage it. The main Grbl interrupt (Timer1 compare)
// sets the direction pins, and does not immediately set the stepper pins, as it would in
// normal operation. The Timer2 compare fires next to set the stepper pins after the step
// pulse delay time, and Timer2 overflow will complete the step pulse, except now delayed
// by the step pulse time plus the step pulse delay. (Thanks langwadt for the idea!)
// NOTE: Uncomment to enable. The recommended delay must be > 3us, and, when added with the
// user-supplied step pulse time, the total time must not exceed 127us. Reported successful
// values for certain setups have ranged from 5 to 20us.
// not ported; don't use. #define STEP_PULSE_DELAY 10 // Step pulse delay in microseconds. Default disabled.
// Creates a delay between setting the direction pin and pulsing the step pin. This delay
// lives inside the main Grbl interrupt.
#define STEP_PULSE_DELAY_NS 200 // Step pulse delay in nanoseconds.
// The number of linear motions in the planner buffer to be planned at any give time. The vast
// majority of RAM that Grbl uses is based on this buffer size. Only increase if there is extra
// available RAM, like when re-compiling for a Mega2560. Or decrease if the Arduino begins to
// crash due to the lack of available RAM or if the CPU is having trouble keeping up with planning
// new incoming motions as they are executed.
#define BLOCK_BUFFER_SIZE 250 // Uncomment to override default in planner.h.
// Governs the size of the intermediary step segment buffer between the step execution algorithm
// and the planner blocks. Each segment is set of steps executed at a constant velocity over a
// fixed time defined by ACCELERATION_TICKS_PER_SECOND. They are computed such that the planner
// block velocity profile is traced exactly. The size of this buffer governs how much step
// execution lead time there is for other Grbl processes have to compute and do their thing
// before having to come back and refill this buffer, currently at ~50msec of step moves.
#define SEGMENT_BUFFER_SIZE 20 // Uncomment to override default in stepper.h.
// Line buffer size from the serial input stream to be executed. Also, governs the size of
// each of the startup blocks, as they are each stored as a string of this size. Make sure
// to account for the available EEPROM at the defined memory address in settings.h and for
// the number of desired startup blocks.
// NOTE: 80 characters is not a problem except for extreme cases, but the line buffer size
// can be too small and g-code blocks can get truncated. Officially, the g-code standards
// support up to 256 characters. In future versions, this default will be increased, when
// we know how much extra memory space we can re-invest into this.
// #define LINE_BUFFER_SIZE 80 // Uncomment to override default in protocol.h
// Serial send and receive buffer size. The receive buffer is often used as another streaming
// buffer to store incoming blocks to be processed by Grbl when its ready. Most streaming
// interfaces will character count and track each block send to each block response. So,
// increase the receive buffer if a deeper receive buffer is needed for streaming and avaiable
// memory allows. The send buffer primarily handles messages in Grbl. Only increase if large
// messages are sent and Grbl begins to stall, waiting to send the rest of the message.
// NOTE: Grbl generates an average status report in about 0.5msec, but the serial TX stream at
// 115200 baud will take 5 msec to transmit a typical 55 character report. Worst case reports are
// around 90-100 characters. As long as the serial TX buffer doesn't get continually maxed, Grbl
// will continue operating efficiently. Size the TX buffer around the size of a worst-case report.
#define RX_BUFFER_SIZE 8192 // Uncomment to override defaults in serial.h
// not ported #define TX_BUFFER_SIZE 100 // (1-254)
// A simple software debouncing feature for hard limit switches. When enabled, the interrupt
// monitoring the hard limit switch pins will enable the Arduino's watchdog timer to re-check
// the limit pin state after a delay of about 32msec. This can help with CNC machines with
// problematic false triggering of their hard limit switches, but it WILL NOT fix issues with
// electrical interference on the signal cables from external sources. It's recommended to first
// use shielded signal cables with their shielding connected to ground (old USB/computer cables
// work well and are cheap to find) and wire in a low-pass circuit into each limit pin.
// #define ENABLE_SOFTWARE_DEBOUNCE // Default disabled. Uncomment to enable.
// Configures the position after a probing cycle during Grbl's check mode. Disabled sets
// the position to the probe target, when enabled sets the position to the start position.
// #define SET_CHECK_MODE_PROBE_TO_START // Default disabled. Uncomment to enable.
// Force Grbl to check the state of the hard limit switches when the processor detects a pin
// change inside the hard limit ISR routine. By default, Grbl will trigger the hard limits
// alarm upon any pin change, since bouncing switches can cause a state check like this to
// misread the pin. When hard limits are triggered, they should be 100% reliable, which is the
// reason that this option is disabled by default. Only if your system/electronics can guarantee
// that the switches don't bounce, we recommend enabling this option. This will help prevent
// triggering a hard limit when the machine disengages from the switch.
// NOTE: This option has no effect if SOFTWARE_DEBOUNCE is enabled.
// #define HARD_LIMIT_FORCE_STATE_CHECK // Default disabled. Uncomment to enable.
// Adjusts homing cycle search and locate scalars. These are the multipliers used by Grbl's
// homing cycle to ensure the limit switches are engaged and cleared through each phase of
// the cycle. The search phase uses the axes max-travel setting times the SEARCH_SCALAR to
// determine distance to look for the limit switch. Once found, the locate phase begins and
// uses the homing pull-off distance setting times the LOCATE_SCALAR to pull-off and re-engage
// the limit switch.

// Defines the EEPROM data restored upon a settings version change and `$RST=*` command. Whenever the
// the settings or other EEPROM data structure changes between Grbl versions, Grbl will automatically
// wipe and restore the EEPROM. This macro controls what data is wiped and restored. This is useful
// particularily for OEMs that need to retain certain data. For example, the BUILD_INFO string can be
// written into the Arduino EEPROM via a seperate .INO sketch to contain product data. Altering this
// macro to not restore the build info EEPROM will ensure this data is retained after firmware upgrades.

// #define SETTINGS_RESTORE_ALL (SETTINGS_RESTORE_DEFAULTS | SETTINGS_RESTORE_PARAMETERS | SETTINGS_RESTORE_STARTUP_LINES | SETTINGS_RESTORE_BUILD_INFO)
// Enable the '$I=(string)' build info write command. If disabled, any existing build info data must
// be placed into EEPROM via external means with a valid checksum value. This macro option is useful
// to prevent this data from being over-written by a user, when used to store OEM product data.
// NOTE: If disabled and to ensure Grbl can never alter the build info line, you'll also need to enable
// the SETTING_RESTORE_ALL macro above and remove SETTINGS_RESTORE_BUILD_INFO from the mask.
// NOTE: See the included grblWrite_BuildInfo.ino example file to write this string seperately.
#define ENABLE_BUILD_INFO_WRITE_COMMAND // '$I=' Default enabled. Comment to disable.
// AVR processors require all interrupts to be disabled during an EEPROM write. This includes both
// the stepper ISRs and serial comm ISRs. In the event of a long EEPROM write, this ISR pause can
// cause active stepping to lose position and serial receive data to be lost. This configuration
// option forces the planner buffer to completely empty whenever the EEPROM is written to prevent
// any chance of lost steps.
// However, this doesn't prevent issues with lost serial RX data during an EEPROM write, especially
// if a GUI is premptively filling up the serial RX buffer simultaneously. It's highly advised for
// GUIs to flag these gcodes (G10,G28.1,G30.1) to always wait for an 'ok' after a block containing
// one of these commands before sending more data to eliminate this issue.
// NOTE: Most EEPROM write commands are implicitly blocked during a job (all '$' commands). However,
// coordinate set g-code commands (G10,G28/30.1) are not, since they are part of an active streaming
// job. At this time, this option only forces a planner buffer sync with these g-code commands.
#define FORCE_BUFFER_SYNC_DURING_EEPROM_WRITE // Default enabled. Comment to disable.
// LPC176x flash blocks have a rating of 10,000 write cycles. To prevent excess wear, we don't

// #define STORE_COORD_DATA // Default disabled. Uncomment to enable.
// In Grbl v0.9 and prior, there is an old outstanding bug where the `WPos:` work position reported
// may not correlate to what is executing, because `WPos:` is based on the g-code parser state, which
// can be several motions behind. This option forces the planner buffer to empty, sync, and stop
// motion whenever there is a command that alters the work coordinate offsets `G10,G43.1,G92,G54-59`.
// This is the simplest way to ensure `WPos:` is always correct. Fortunately, it's exceedingly rare
// that any of these commands are used need continuous motions through them.
#define FORCE_BUFFER_SYNC_DURING_WCO_CHANGE // Default enabled. Comment to disable.
// By default, Grbl disables feed rate overrides for all G38.x probe cycle commands. Although this
// may be different than some pro-class machine control, it's arguable that it should be this way.
// Most probe sensors produce different levels of error that is dependent on rate of speed. By
// keeping probing cycles to their programmed feed rates, the probe sensor should be a lot more
// repeatable. If needed, you can disable this behavior by uncommenting the define below.
// #define ALLOW_FEED_OVERRIDE_DURING_PROBE_CYCLES // Default disabled. Uncomment to enable.
// Enables and configures parking motion methods upon a safety door state. Primarily for OEMs
// that desire this feature for their integrated machines. At the moment, Grbl assumes that
// the parking motion only involves one axis, although the parking implementation was written
// to be easily refactored for any number of motions on different axes by altering the parking
// source code. At this time, Grbl only supports parking one axis (typically the Z-axis) that
// moves in the positive direction upon retracting and negative direction upon restoring position.
// The motion executes with a slow pull-out retraction motion, power-down, and a fast park.
// Restoring to the resume position follows these set motions in reverse: fast restore to
// pull-out position, power-up with a time-out, and plunge back to the original position at the
// slower pull-out rate.
// NOTE: Still a work-in-progress. Machine coordinates must be in all negative space and
// does not work with HOMING_FORCE_SET_ORIGIN enabled. Parking motion also moves only in
// positive direction.

// This option will automatically disable the laser during a feed hold by invoking a spindle stop
