/**
* Roxy's G26 Mesh Validation Tool
*
*
* G26 Is a Mesh Validation Tool intended to provide support for the Marlin Unified Bed Leveling System.
* In order to fully utilize and benefit from the Marlin Unified Bed Leveling System an accurate Mesh must
* be defined. G29 is designed to allow the user to quickly validate the correctness of her Mesh. It will
* first heat the bed and nozzle. It will then print lines and circles along the Mesh Cell boundaries and
* the intersections of those lines (respectively).
*
*
* This action allows the user to immediately see where the Mesh is properly defined and where it needs to
* be edited. The command will generate the Mesh lines closest to the nozzle's starting position. Alternatively
* the user can specify the X and Y position of interest with command parameters. This allows the user to
* focus on a particular area of the Mesh where attention is needed.
*
*
* B # Bed Set the Bed Temperature. If not specified, a default of 60 C. will be assumed.
*
*
* C Current When searching for Mesh Intersection points to draw, use the current nozzle location
* as the base for any distance comparison.
*
*
* D Disable Disable the Unified Bed Leveling System. In the normal case the user is invoking this
* command to see how well a Mesh as been adjusted to match a print surface. In order to do
* this the Unified Bed Leveling System is turned on by the G26 command. The D parameter
* alters the command's normal behaviour and disables the Unified Bed Leveling System even if
* it is on.
*
*
* H # Hotend Set the Nozzle Temperature. If not specified, a default of 205 C. will be assumed.
*
*
* F # Filament Used to specify the diameter of the filament being used. If not specified
* 1.75mm filament is assumed. If you are not getting acceptable results by using the
* 'correct' numbers, you can scale this number up or down a little bit to change the amount
* of filament that is being extruded during the printing of the various lines on the bed.
*
*
* K Keep-On Keep the heaters turned on at the end of the command.
*
*
* L # Layer Layer height. (Height of nozzle above bed) If not specified .20mm will be used.
*
*
* Q # Multiplier Retraction Multiplier. Normally not needed. Retraction defaults to 1.0mm and
* un-retraction is at 1.2mm These numbers will be scaled by the specified amount
*
*
* N # Nozzle Used to control the size of nozzle diameter. If not specified, a .4mm nozzle is assumed.
*
*
* O # Ooooze How much your nozzle will Ooooze filament while getting in position to print. This
* is over kill, but using this parameter will let you get the very first 'cicle' perfect
* so you have a trophy to peel off of the bed and hang up to show how perfectly you have your
* Mesh calibrated. If not specified, a filament length of .3mm is assumed.
*
*
* P # Prime Prime the nozzle with specified length of filament. If this parameter is not
* given, no prime action will take place. If the parameter specifies an amount, that much
* will be purged before continuing. If no amount is specified the command will start
* purging filament until the user provides an LCD Click and then it will continue with
* printing the Mesh. You can carefully remove the spent filament with a needle nose
* pliers while holding the LCD Click wheel in a depressed state.
*
*
* R # Random Randomize the order that the circles are drawn on the bed. The search for the closest
* undrawn cicle is still done. But the distance to the location for each circle has a
* random number of the size specified added to it. Specifying R50 will give an interesting
* deviation from the normal behaviour on a 10 x 10 Mesh.
*
*
* X # X coordinate Specify the starting location of the drawing activity.
*
*
* Y # Y coordinate Specify the starting location of the drawing activity.
