I can help you generate the g-code for this project by writing a script to generate the code. The g-code consists of two parts: cutting and pocketing operations. Let's start with the cutting operation. ### Step 1: Cut Operation ```python def cutting_g_code(n, points): f = open('gcode_cutter.txt', 'w') for i in range(len(points)): point = points[i] if (i + 1) % n == 0: line = 'G01 F120 Z{0:03.3f}\n'.format(point[2]) elif (i - 1) % n != 0 and i != len(points) - 1: next_point = points[i + 1] if (next_point[1] > point[1]) or \ (next_point[1] == point[1] and next_point[2] < point[2]): line = 'G00 F500 Z{0:03.3f}\n'.format(next_point[2]) # Go up in height with the mill, not the drill press. elif (next_point[1] < point[1]) or \ (next_point[1] == point[1] and next_point[2] > point[2]): line = 'G00 F500 X{0:05.4f}\n'.format(next_point[0]) elif i != 0: prev_point = points[i - 1] if (prev_point[1] < point[1]) or \ (prev_point[1] == point[1] and prev_point[2] > point[2]): line = 'G00 F500 X{0:05.4f}\n'.format(prev_point[0]) # Go up in height with the mill, not the drill press. elif i % n != 0: if point[1] == -12.657534246575342 and (i + 2) % n == 0: line = 'G00 F500 X{0:05.4f}\n'.format(-3.7808219178082196) # If we are already cutting, continue moving. f.write(line) f.close() points = [ [-20.21878082191782, -5.424657534246575,-1], [-19.563443835616436, -7.26849284149624 ,-1], [-17.90010684931504 , -9.112327948745904,-2], [-16.23677086301366, -11.95616305599566,0] ] # Parameters: cutter length in number of points and cutter parameters. cutting_g_code(1000, points) ``` Now that the script has written this code into a file named gcode_cutter.txt we need to copy it over into the main .nc code file. ### Step 2: Copying the Code We can now write the pocket operation g-code using similar steps: ### Step 3: Pocket Operation ```python import math def cutting_g_code(points): f = open('gcode_cutter.txt', 'a') def generate_cuts(polygon, num): point1 = polygon[0] cuts = [] while True: closest_point = find_closest_polygon_point(point1, polygon) distance = calculate_distance_between_two_points( point1, closest_point ) next_point = point1 + ((closest_point - point1).rotate(math.radians(30)) * num/ (distance*6) cuts.append(calculate_center_point(point1, closest_point, math.ceil(num/12), 10 )) if calculate_distance_between_two_points(next_point, next_point - closest_point + (next_point - point1))\ <num: return cut = generate_segment_g_code(points=next_point.next_point.next_point.points) def segment_g_code(polygon): f.write( """ G21 M8 S10 T4 {} G17 M6 S120 T12 G04 X100 Z1.25 D00 F400.0 P15. """)\ ''.format('\n'.join(['M8 {} T3 '.format(point) for point in points])) segment_g_code(polygon=points) segment_g_code(polygon=[(17.26027397260274,13.899543378995432), (-20.21878082191782,-5.424657534246575), (7.068493150684932 ,10.684931506849316)]) ``` With these operations the script will produce g-code in `gcode.txt`.
