#define ACCELERATION_RAMPING

acceleration and deceleration ramping.

Each movement starts at (almost) no speed, linearly accelerates to target speed and decelerates just in time to smoothly stop at the target. alternative to ACCELERATION_REPRAP

#define BAUD 115200

Baud rate for the connection to the host.

Usually 115200, other common values are 19200, 38400 or 57600.

#define HEATER_EXTRUDER HEATER_extruder

and now because the c preprocessor isn't as smart as it could be, uncomment the ones you've listed above and comment the rest.

these are used to enable various capability-specific chunks of code, you do NOT need to create new entries unless you are adding new capabilities elsewhere in the code! so if you list a bed above, uncomment HEATER_BED, but if you list a chamber you do NOT need to create HEATED_CHAMBER I have searched high and low for a way to make the preprocessor do this for us, but so far I have not found a way.

#define HOST

This is the motherboard, as opposed to the extruder.

See extruder/ directory for GEN3 extruder firmware

#define MOVEBUFFER_SIZE 8

move buffer size, in number of moves note that each move takes a fair chunk of ram (69 bytes as of this writing) so don't make the buffer too big - a bigger serial readbuffer may help more than increasing this unless your gcodes are more than 70 characters long on average.

however, a larger movebuffer will probably help with lots of short consecutive moves, as each move takes a bunch of math (hence time) to set up so a longer buffer allows more of the math to be done during preceding longer moves

#define REPRAP_HOST_COMPATIBILITY 20100806

RepRap Host changes it's communications protocol from time to time and intentionally avoids backwards compatibility.

Set this to the date the source code of your Host was fetched from RepRap's repository, which is likely also the build date. See the discussion on the reprap-dev mailing list from 11 Oct. 2010.

Undefine it for best human readability, set it to an old date for compatibility with hosts before August 2010

#define STEP_INTERRUPT_INTERRUPTIBLE 1

this option makes the step interrupt interruptible (nested).

this should help immensely with dropped serial characters, but may also make debugging infuriating due to the complexities arising from nested interrupts

#define TEMP_HYSTERESIS 20

TEMP_HYSTERESIS: actual temperature must be target +/- hysteresis before target temperature can be achieved.

NOTE: format is 30.2 fixed point, so value of 20 actually means +/- 5 degrees

#define TEMP_RESIDENCY_TIME 60

TEMP_RESIDENCY_TIME: actual temperature must be close to target for this long before target is achieved.

temperature is "achieved" for purposes of M109 and friends when actual temperature is within [hysteresis] of target for [residency] seconds
