// The temporal resolution of the acceleration management subsystem. Higher number give smoother

// round-off can be great enough to cause problems and/or it's too fast for the Arduino. The correct

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

#define MINIMUM_PLANNER_SPEED 0.0 // (mm/min)
// Minimum stepper rate. Sets the absolute minimum stepper rate in the stepper program and never runs
// slower than this value, except when sleeping. This parameter overrides the minimum planner speed.
// This is primarily used to guarantee that the end of a movement is always reached and not stop to
// never reach its target. This parameter should always be greater than zero.
#define MINIMUM_STEPS_PER_MINUTE 800 // (steps/min) - Integer value only
// 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)
// 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
// The homing cycle seek and feed rates will adjust so all axes independently move at the homing
// seek and feed rates regardless of how many axes are in motion simultaneously. If disabled, rates
// are point-to-point rates, as done in normal operation. For example in an XY diagonal motion, the
// diagonal motion moves at the intended rate, but the individual axes move at 70% speed. This option
// just moves them all at 100% speed.
#define HOMING_RATE_ADJUST // Comment to disable
// Define the homing cycle search patterns with bitmasks. The homing cycle first performs a search
// to engage the limit switches. HOMING_SEARCH_CYCLE_x are executed in order starting with suffix 0
// and searches the enabled axes in the bitmask. This allows for users with non-standard cartesian
// machines, such as a lathe (x then z), to configure the homing cycle behavior to their needs.
// Search cycle 0 is required, but cycles 1 and 2 are both optional and may be commented to disable.
// After the search cycle, homing then performs a series of locating about the limit switches to hone
// in on machine zero, followed by a pull-off maneuver. HOMING_LOCATE_CYCLE governs these final moves,
// and this mask must contain all axes in the search.
// NOTE: Later versions may have this installed in settings.
#define HOMING_SEARCH_CYCLE_0 (1<<Z_AXIS) // First move Z to clear workspace.
#define HOMING_SEARCH_CYCLE_1 ((1<<X_AXIS)|(1<<Y_AXIS)) // Then move X,Y at the same time.
// #define HOMING_SEARCH_CYCLE_2 // Uncomment and add axes mask to enable
#define HOMING_LOCATE_CYCLE ((1<<X_AXIS)|(1<<Y_AXIS)|(1<<Z_AXIS)) // Must contain ALL search axes
// Number of homing cycles performed after when the machine initially jogs to limit switches.
// This help in preventing overshoot and should improve repeatability. This value should be one or
// greater.
#define N_HOMING_LOCATE_CYCLE 2 // Integer (1-128)
// Number of blocks Grbl executes upon startup. These blocks are stored in EEPROM, where the size
// and addresses are defined in settings.h. With the current settings, up to 5 startup blocks may
// be stored and executed in order. These startup blocks would typically be used to set the g-code
// parser state depending on user preferences.
#define N_STARTUP_LINE 2 // Integer (1-5)
// ---------------------------------------------------------------------------------------
// FOR ADVANCED USERS ONLY:
// 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 Teensy or Sanguino. 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 18 // Uncomment to override default in planner.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: 50 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 50 // 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.
// #define RX_BUFFER_SIZE 128 // Uncomment to override defaults in serial.h
// #define TX_BUFFER_SIZE 64
// Toggles XON/XOFF software flow control for serial communications. Not officially supported
// due to problems involving the Atmega8U2 USB-to-serial chips on current Arduinos. The firmware
// on these chips do not support XON/XOFF flow control characters and the intermediate buffer
// in the chips cause latency and overflow problems with standard terminal programs. However,
// using specifically-programmed UI's to manage this latency problem has been confirmed to work.
// As well as, older FTDI FT232RL-based Arduinos(Duemilanove) are known to work with standard
// terminal programs since their firmware correctly manage these XON/XOFF characters. In any
// case, please report any successes to grbl administrators!
// #define ENABLE_XONXOFF // Default disabled. Uncomment to enable.
// 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!)
// This is an experimental feature that should only be used if your setup requires a longer
// delay between direction and step pin settings (some opto coupler based drivers), as it may
// adversely effect Grbl's high-end performance (>10kHz). Please notify Grbl administrators
// of your successes or difficulties, as we will monitor this and possibly integrate this as a
// standard feature for future releases. However, we suggest to first try our direction delay
// hack/solution posted in the Wiki involving inverting the stepper pin mask.
// NOTE: Uncomment to enable. The recommended delay must be > 3us and the total step pulse
// time, which includes the Grbl settings pulse microseconds, must not exceed 127us. Reported
// successful values for certain setups have ranged from 10 to 20us.
// #define STEP_PULSE_DELAY 10 // Step pulse delay in microseconds. Default disabled.
