Load File - open a .drl gerber file
Com1/Open - selects/opens a com port for serial connection
Drill Sizes - A list of differernt hole sizes in this file, up to 6 can be shown
Hole List - Contains all holes of selected Drill Sizes, displayed in 4 columns, hole number, x and y coordinates and drill number. This will be the order and list of hole co-ordinates that will be sent to the Drill when Run is selected.
Min. hole space - the minimum acceptable distance between 2 holes.
Optimise - This puts all the holes in the Hole List into an order that requires the least amount of movement of x and y. It also checks the hole spacing set in Min hole space
Scale/Rescale - The entire screen can be scaled to allow for errors when the PCB was reproduced through printer errors both on x and y axis. It has a resolution of 0.05% being about 1/1000" per 2" and the image is redisplayed on screen (tested but never used)
Mirror - Flips all hole positions horizontally
Trace - When selected shows on screen the path the drill will take when drilling all the holes. (This should be next to Optimise)
Cursor/Set - Shows the position of the yellow cross hairs on screen. These can be altered and Set pressed to force the Drill to accept the new co-ordicates as its current location (tested but never used)
Selection - If the user draws a box on screen, only the holes within that box will be shown and the Selection option as pressed. Release this option to unselect holes
Grid Offset - Can move all holes in any direction - effectively moving the entire PCB (tested but never used)
Send Cursor - Sends instructions for drill to move to cursor coordinates
Drill - Sends instruction to the Drill to activate a drill down/up sequence.
Home - Moves drill to position 0,0. This does not calibrate the drill the same as the Home button on the keyboard does
On/Off - Instructs the Drill to switch the drill motor on or off.
Clear - Clears all text in the text box
Get Position - Sends instruction to the Drill to return the current position it has for the drill
Run - Starts drilling the holes in the Hole List starting with the selected entry.
