//Implemented Codes
|
|
//-------------------
|
|
// G0 -> G1
|
|
// G1 - Coordinated Movement X Y Z E
|
|
// G2 - CW ARC
|
|
// G3 - CCW ARC
|
|
// G4 - Dwell S<seconds> or P<milliseconds>
|
|
// G28 - Home all Axis
|
|
// G90 - Use Absolute Coordinates
|
|
// G91 - Use Relative Coordinates
|
|
// G92 - Set current position to cordinates given
|
|
|
|
//RepRap M Codes
|
|
// M104 - Set extruder target temp
|
|
// M105 - Read current temp
|
|
// M106 - Fan on
|
|
// M107 - Fan off
|
|
// M109 - Wait for extruder current temp to reach target temp.
|
|
// M114 - Display current position
|
|
|
|
//Custom M Codes
|
|
// M20 - List SD card
|
|
// M21 - Init SD card
|
|
// M22 - Release SD card
|
|
// M23 - Select SD file (M23 filename.g)
|
|
// M24 - Start/resume SD print
|
|
// M25 - Pause SD print
|
|
// M26 - Set SD position in bytes (M26 S12345)
|
|
// M27 - Report SD print status
|
|

|
|
// M30 - Output time since last M109 or SD card start to serial
|
|
// M42 - Change pin status via gcode
|
|
// M80 - Turn on Power Supply
|
|
// M81 - Turn off Power Supply
|
|
// M82 - Set E codes absolute (default)
|
|
// M83 - Set E codes relative while in Absolute Coordinates (G90) mode
|
|
// M84 - Disable steppers until next move,
|
|
// or use S<seconds> to specify an inactivity timeout, after which the steppers will be disabled. S0 to disable the timeout.
|
|
// M85 - Set inactivity shutdown timer with parameter S<seconds>. To disable set zero (default)
|
|
// M92 - Set axis_steps_per_unit - same syntax as G92
|
|
// M115 - Capabilities string
|
|
// M140 - Set bed target temp
|
|
// M190 - Wait for bed current temp to reach target temp.
|
|
// M200 - Set filament diameter
|
|
// M201 - Set max acceleration in units/s^2 for print moves (M201 X1000 Y1000)
|
|
// M202 - Set max acceleration in units/s^2 for travel moves (M202 X1000 Y1000) Unused in Marlin!!
|
|
// M203 - Set maximum feedrate that your machine can sustain (M203 X200 Y200 Z300 E10000) in mm/sec
|
|
// M204 - Set default acceleration: S normal moves T filament only moves (M204 S3000 T7000) im mm/sec^2 also sets minimum segment time in ms (B20000) to prevent buffer underruns and M20 minimum feedrate
|
|
// M205 - advanced settings: minimum travel speed S=while printing T=travel only, B=minimum segment time X= maximum xy jerk, Z=maximum Z jerk
|
|
// M220 - set speed factor override percentage S:factor in percent
|
|
// M301 - Set PID parameters P I and D
|
|
// M500 - stores paramters in EEPROM
|
|
// M501 - reads parameters from EEPROM (if you need reset them after you changed them temporarily). D
|
|
// M502 - reverts to the default "factory settings". You still need to store them in EEPROM afterwards if you want to.

We need to calculate the center of the circle that has the designated radius and passes
|
|
through both the current position and the target position. This method calculates the following
|
|
set of equations where [x,y] is the vector from current to target position, d == magnitude of
|
|
that vector, h == hypotenuse of the triangle formed by the radius of the circle, the distance to
|
|
the center of the travel vector. A vector perpendicular to the travel vector [-y,x] is scaled to the
|
|
length of h [-y/d*h, x/d*h] and added to the center of the travel vector [x/2,y/2] to form the new point
|
|
[i,j] at [x/2-y/d*h, y/2+x/d*h] which will be the center of our arc.
|
|
|
|
d^2 == x^2 + y^2
|
|
h^2 == r^2 - (d/2)^2
|
|
i == x/2 - y/d*h

j == y/2 + x/d*h

C - Current position
|

T - Target position
|
|
O - center of circle that pass through both C and T
|
|
d - distance from C to T
|
|
r - designated radius
|
|
h - distance from center of CT to O
|
|
|
|
Expanding the equations:
|
|
|
|
d -> sqrt(x^2 + y^2)
|
|
h -> sqrt(4 * r^2 - x^2 - y^2)/2
|
|
i -> (x - (y * sqrt(4 * r^2 - x^2 - y^2)) / sqrt(x^2 + y^2)) / 2
|
|
j -> (y + (x * sqrt(4 * r^2 - x^2 - y^2)) / sqrt(x^2 + y^2)) / 2
|
|
|
|
Which can be written:
|
|
|
|
i -> (x - (y * sqrt(4 * r^2 - x^2 - y^2))/sqrt(x^2 + y^2))/2
|
|
j -> (y + (x * sqrt(4 * r^2 - x^2 - y^2))/sqrt(x^2 + y^2))/2
|
|
|
|
Which we for size and speed reasons optimize to:
|
|
|
|
h_x2_div_d = sqrt(4 * r^2 - x^2 - y^2)/sqrt(x^2 + y^2)
|

i = (x - (y * h_x2_div_d))/2
