Adapt to the new Marlin FW version: fix M114 output parser
Bugfix: set explicit feedrate in G1 when homing (home() and home_z())
test-movez.py: new commands: H (home z), z (go z (raw)), rename command z->Z (go z (processed))
Temperature calibration: 1. thermistor against Hg thermometer; 2. thermistor mounted on extruder against thermocouple in the tip of an empty extruder
test-movez.py: new commands

New commands: X,Y,Z Cartesian movez; x,y,z motor moves
Scripts

run-proxy  start Arduino Unix socket proxy in a new window
run-temp  start temperature logger in a new window
init-M301.sh  init PID parameters
ard  send command line arguments to Arduino proxy and echo the answer
G-code extrusion test scripts

retract  retract filament out of heating barrel (hot end)
test-extr{,2,3}  extrusion into air test scripts
ardcat: start Arduino proxy terminal

Arduino proxy terminal using nc command
Add G-code coordinate transformer + sender (incl. initiation): send-g0.py
Add forgotten temperature logger script

temp  the temperature logger script
gp-dat-prep.awk: add parentheses to the output to ensure correct ops order
Geometry recalibration

1) Calibrate extruder nozzle tip position.
2) Calibrate table edge directions and corner absolute position
3) coord.gpinc & fit-dist.gp: support for nozzle tip position parameters and absolute positioning parameters
robot_geom.py: update robot geometry

1) Update geometry parameters:
1.1) now nozzle position, was pen/probe position;
1.2) now x axis parallel to table edge, was arbitrary;
1.3) now origin at near (not at) right front table corner, was at table revolution point.
2) Temporarily remove table wheel excentricity correction, since it needs recalibration.
3) Add coordinate naming convention comment
Fix bug: feedrate racalculation was wrong

Was d/d_raw, should have been d_raw/d.
marlin_ak.py: extrusion support

1) Support for extrusion coordinate in go() and goraw.
2) New option to turn off extrusion to test head movement: MarlinCmd[G].extrude
gen-cyl/*.awk: [quasi]cylindric objects G-code generators

geng-cyl.awk  single wall circular cylinder
geng-cyl-waved.awk  same, but with waved walls, not circular
geng-cyl-2pass.awk  double wall cylinder, circular (ring) cross-sections
