/** \def KINEMATICS_STRAIGHT KINEMATICS_COREXY
This defines the type of kinematics your printer uses. That's essential!
Valid values (see dda_kinematics.h):
KINEMATICS_STRAIGHT
Motors move axis directions directly. This is the
traditional type, found in many printers, including
Mendel, Prusa i3, Mendel90, Ormerod, Mantis.
KINEMATICS_COREXY
A bot using CoreXY kinematics. Typical for CoreXY
are long and crossing toothed belts and a print head
moving on the X-Y-plane.

/** \def ENDSTOP_CLEARANCE_X ENDSTOP_CLEARANCE_Y ENDSTOP_CLEARANCE_Z
When hitting an endstop, Teacup properly decelerates instead of doing an
aprupt stop to save your mechanics. Ineviteably, this means it overshoots
the endstop trigger point by some distance.
To deal with this, Teacup adapts homing movement speeds to what your
endstops can deal with. The higher the allowed acceleration ( = deceleration,
see #define ACCELERATION) and the more clearance the endstop comes with,
the faster Teacup will do homing movements.
Set here how many micrometers (mm * 1000) your endstop allows the carriage
to overshoot the trigger point. Typically 1000 or 2000 for mechanical
endstops, more for optical ones. You can set it to zero, in which case
SEARCH_FEEDRATE_{XYZ} is used, but expect very slow homing movements.

Not defining them at all will disable limits checking and make the binary
about 250 bytes smaller. Enabling only some of them is perfectly fine.

/** \def MAX_JERK_X MAX_JERK_Y MAX_JERK_Z MAX_JERK_E
When performing look-ahead, we need to decide what an acceptable jerk to the
mechanics is. Look-ahead attempts to instantly change direction at movement
crossings, which means instant changes in the speed of the axes participating
in the movement. Define here how big the speed bumps on each of the axes is
allowed to be.
If you want a full stop before and after moving a specific axis, define
MAX_JERK of this axis to 0. This is often wanted for the Z axis. If you want
to ignore jerk on an axis, define it to twice the maximum feedrate of this
axis.
Having these values too low results in more than neccessary slowdown at
movement crossings, but is otherwise harmless. Too high values can result
in stepper motors suddenly stalling. If angles between movements in your
G-code are small and your printer runs through entire curves full speed,
there's no point in raising the values.

Instrument Engineer's Handbook, 4th ed, Vol 2 p126 says values of

so don't make the buffer too big. 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.

Teacup offers two PWM frequencies, 76(61) Hz and 78000(62500) Hz on a

choice and reduces MOSFET heating. Drawback is, in a quiet environment you
might notice the heaters and your power supply humming.

a hotter MOSFET or want faster PWM for other reasons.
