5.7 HOME position and registration hole system
The HOME position must be on the machine's axis of symmetry
(registration hole system) to ensure correct alignment of a double-sided
base.
Double-sided base are rotated about this axis of symmetry.
Inaccuracies in the HOME position result in misalignment when double-
sided base are rotated during the machining process.
The HOME position is contained on the configuration diskette supplied
as standard. With the
BoardMaster
program and configuration diskette
correctly installed, the HOME position corresponds to the setting for the
x/y coordinates as measured during the acceptance test.
Note: The registration hole system can only be guaranteed to be
parallel for the current position of the registration hole strips.
The front registration hole slide must be pushed against the pin in
the reference groove (reference point).
An additional hole must be drilled in the rear registration hole strip
for each format if base material of different sizes is used.
To do this, move from the HOME position towards the rear
registration hole strip.
Now move the rear registration hole strip to the required position.
Once the necessary tool change has been made automatically (2.95
mm drill with a different colour spacer ring must be positioned in
the tool magazine by now), another hole is drilled in the slide.
The position of the slide for the various holes should be recorded
or marked on the circuit board plotter.
This guarantees parallelism for different formats.
You will need to perform a test run on the machine to check the
coordinates of the HOME position on new machines and after
transporting the system.
The individual steps are described in the next section (see „Checking
and correcting the HOME position“ on page 35.).
No further action is required if the preset coordinates are correct. If this
is not the case, the corrected coordinates will have to be entered in
BoardMaster
(see „Programming the HOME position in LPKF
BoardMaster“ on page 39.).
5.8 Checking and correcting the HOME position
The test file Null-Pkt.LMD is supplied with the installation program to
simplify the procedure for checking the HOME position.
This program drills a hole on one side of the board and then rotates the
board before milling a circle in the same place. This allows you to
perform a visual check on the position of the Home point on both axes.
