60
|
+ * G26 Mesh Validation Tool
|
|
|
61
|
+ *
|
|
|
62
|
+ * G26 is a Mesh Validation Tool intended to provide support for the Marlin Unified Bed Leveling System.
|
|
|
63
|
+ * In order to fully utilize and benefit from the Marlin Unified Bed Leveling System an accurate Mesh must
|
|
|
64
|
+ * be defined. G29 is designed to allow the user to quickly validate the correctness of her Mesh. It will
|
|
|
65
|
+ * first heat the bed and nozzle. It will then print lines and circles along the Mesh Cell boundaries and
|
|
|
66
|
+ * the intersections of those lines (respectively).
|
|
|
67
|
+ *
|
|
|
68
|
+ * This action allows the user to immediately see where the Mesh is properly defined and where it needs to
|
|
|
69
|
+ * be edited. The command will generate the Mesh lines closest to the nozzle's starting position. Alternatively
|
|
|
70
|
+ * the user can specify the X and Y position of interest with command parameters. This allows the user to
|
|
|
71
|
+ * focus on a particular area of the Mesh where attention is needed.
|
|
|
72
|
+ *
|
|
|
73
|
+ * B # Bed Set the Bed Temperature. If not specified, a default of 60 C. will be assumed.
|
|
|
74
|
+ *
|
|
|
75
|
+ * C Current When searching for Mesh Intersection points to draw, use the current nozzle location
|
|
|
76
|
+ * as the base for any distance comparison.
|
|
|
77
|
+ *
|
|
|
78
|
+ * D Disable Disable the Unified Bed Leveling System. In the normal case the user is invoking this
|
|
|
79
|
+ * command to see how well a Mesh as been adjusted to match a print surface. In order to do
|
|
|
80
|
+ * this the Unified Bed Leveling System is turned on by the G26 command. The D parameter
|
|
|
81
|
+ * alters the command's normal behaviour and disables the Unified Bed Leveling System even if
|
|
|
82
|
+ * it is on.
|
|
|
83
|
+ *
|
|
|
84
|
+ * H # Hotend Set the Nozzle Temperature. If not specified, a default of 205 C. will be assumed.
|
|
|
85
|
+ *
|
|
|
86
|
+ * F # Filament Used to specify the diameter of the filament being used. If not specified
|
|
|
87
|
+ * 1.75mm filament is assumed. If you are not getting acceptable results by using the
|
|
|
88
|
+ * 'correct' numbers, you can scale this number up or down a little bit to change the amount
|
|
|
89
|
+ * of filament that is being extruded during the printing of the various lines on the bed.
|
|
|
90
|
+ *
|
|
|
91
|
+ * K Keep-On Keep the heaters turned on at the end of the command.
|
|
|
92
|
+ *
|
|
|
93
|
+ * L # Layer Layer height. (Height of nozzle above bed) If not specified .20mm will be used.
|
|
|
94
|
+ *
|
|
|
95
|
+ * O # Ooooze How much your nozzle will Ooooze filament while getting in position to print. This
|
|
|
96
|
+ * is over kill, but using this parameter will let you get the very first 'circle' perfect
|
|
|
97
|
+ * so you have a trophy to peel off of the bed and hang up to show how perfectly you have your
|
|
|
98
|
+ * Mesh calibrated. If not specified, a filament length of .3mm is assumed.
|
|
|
99
|
+ *
|
|
|
100
|
+ * P # Prime Prime the nozzle with specified length of filament. If this parameter is not
|
|
|
101
|
+ * given, no prime action will take place. If the parameter specifies an amount, that much
|
|
|
102
|
+ * will be purged before continuing. If no amount is specified the command will start
|
|
|
103
|
+ * purging filament until the user provides an LCD Click and then it will continue with
|
|
|
104
|
+ * printing the Mesh. You can carefully remove the spent filament with a needle nose
|
|
|
105
|
+ * pliers while holding the LCD Click wheel in a depressed state. If you do not have
|
|
|
106
|
+ * an LCD, you must specify a value if you use P.
|
|
|
107
|
+ *
|
|
|
108
|
+ * Q # Multiplier Retraction Multiplier. Normally not needed. Retraction defaults to 1.0mm and
|
|
|
109
|
+ * un-retraction is at 1.2mm These numbers will be scaled by the specified amount
|
|
|
110
|
+ *
|
|
|
111
|
+ * R # Repeat Prints the number of patterns given as a parameter, starting at the current location.
|
|
|
112
|
+ * If a parameter isn't given, every point will be printed unless G26 is interrupted.
|
|
|
113
|
+ * This works the same way that the UBL G29 P4 R parameter works.
|
|
|
114
|
+ *
|
|
|
115
|
+ * NOTE: If you do not have an LCD, you -must- specify R. This is to ensure that you are
|
|
|
116
|
+ * aware that there's some risk associated with printing without the ability to abort in
|
|
|
117
|
+ * cases where mesh point Z value may be inaccurate. As above, if you do not include a
|
|
|
118
|
+ * parameter, every point will be printed.
|
|
|
119
|
+ *
|
|
|
120
|
+ * S # Nozzle Used to control the size of nozzle diameter. If not specified, a .4mm nozzle is assumed.
|
|
|
121
|
+ *
|
|
|
122
|
+ * U # Random Randomize the order that the circles are drawn on the bed. The search for the closest
|
|
|
123
|
+ * undrawn cicle is still done. But the distance to the location for each circle has a
|
|
|
124
|
+ * random number of the size specified added to it. Specifying S50 will give an interesting
|
|
|
125
|
+ * deviation from the normal behaviour on a 10 x 10 Mesh.
|
|
|
126
|
+ *
|
|
|
127
|
+ * X # X Coord. Specify the starting location of the drawing activity.
|
|
|
128

|
|

129
