The existing junction algorithm limits the speed between two moves by
determining the maximum speed an arc between those two moves would
have if the cetripetal acceleration of that arc did not exceed the
printer's maximum acceleration.
However, should the slicer send an actual arc to the printer, then the
existing junction algorithm would not impose any significant limit on
the travel speed of that arc. This would permit the head to travel in
a circle at high velocity and with a greater centripetal acceleration
than the printer's maximum acceleration. To avoid this, impose a
limit on the junction velocity of short moves so that an approximate
centripetal acceleration of that move does not exceed the move's
acceleration limit.

Apply the bed tilt settings immediately after finding them. This
makes it easier for users to perform automatic tilt calibration at the
start of every print.

Drop support for M303 and PID_TUNE, and replace it with a new
PID_CALIBRATE command. Move the logic for this command from heater.py
to a new pid_calibrate.py file in the extras/ directory.

Move the probe_z_offset parameter from delta_calibrate and
bed_tilt_calibrate to a z_offset parameter within the probe config
section. It's easier to understand the z offset setting when it is in
the probe config section.

If a z_virtual_endstop is in use, then record the last XY position
that is used when the Z is homed. Use that XY position to report what
change is needed to the z position_endstop.

It looks like OctoPrint is expecting the result from M114 to be
relative to the last G92 command. Also, introduce GET_POSITION to
report the actual location that the printer is at.

If a heater falls out of the target range, accumulate the temperature
differences to determine if an error should be raised. This should
make it less likely to report an error for heaters that drift slightly
out of range, and it should make error reporting faster for heaters
that rapidly fall out of range.

I've added the LCD configuration for the Tronxy X5S printer and its

I've also added the pins for the encoder, but that is untested.
