Take note: Do not fiddle with settings in this program or in the program for the laser itself. Only follow these instructions to prepeare your design for structuring. If the wrong settings are changed figuring out how to get the software back in working condition could take a long time. If something does not work out contact Olav or Kristian.

Contents

Start up procedure

The software is located on one computer next to the milling machine. This is a temporary thin as we are waiting for a new version of the software.

Using the software

Import

Start by importing your design. To make things easy for yourself have the files in gerber format.

File - Import

The important thing here is to check that what you see is what you want. The best indication of that is the visual and the format/size field in the import screen. If the format/size seems to be of you need to fix this by manipulating the leading and/or trailing zeros. This is generaly a chalangs related to the drillholes.

Only the layers with a green button is importet. Adjust the Layer/Template field to an appropriat setting for each layer you wish to import.

Manipulating your data

What you are going to do now is to generate the work instructions for the laser. That is that every tiny movement the milling machine is going to has to be generated.

Rubout

We start by generating the rubout areas, for the top and bottom plate. The layers we need are the TopLayer (cond.gbr), BottomLayer (cond2.gbr) and BoardOutline (bound.gbr).

Layers not in use at the moment can be made invisible and uneditable by clicking the green button, making it red.


To do the rubout start with the menu:

Tool Path - Protolaser Rubout

Use the "Base Layer" as either your TopLayer or BottomLayer, leave the "Rubout Layer" to your BoardOutline. You must use either ProtoLaserTop or ProtoLaserBottom for the "Destination layer". The following image shows the setup for the bottom layer, repeat this step for the top layer.

Do not change other setting than those given here, though you may change the "Calculation grid" to a smaller value if you have tiny features. Summarized:

Choose the side, Top or Bottom
The Name is either ProtoLaserBottom or ProtoLaserTop
Change the layers as suits you. 
 The Base Layer is the layer you 'work on', 
 the Rubout layer is the limiting layer and 
 the destination layer is where everything ends up and should be either ProtoLaserBottom or ProtoLaserTop.
Press the Run botton (OK just make you leave the page without running the job.)
Three or four new layers are generated for eatch layer.

Drilling

Now it is time to make the drill holes. What we do is that we make several rings and use the laser in several steps traveling in the z-direction on the machine to make the holes.

Select all the holes. What we need to do now is to change the diameter of the hole into a line the laser can follow. We make one cicle following the edge of the hole and than more lines (more for thicker substrates) inside the first one to make a good hole.

Select all the holes.
Then Modify - Convert to closed outlines. We now have the lines we want.
To make more holes 'inside' the first circle use Tools path - Counter Routing several times. 
 Remember to use the previous made cicle to make the nextone, otherwise you just make them on top of one another.

Do as the picture show above. 
Inside
Source should be a Layer to avoid problems in case you by misstake did not select everything in the layer.
You make up the destination layer yourself. Make a good name. 
Use the layer you made the next time (So you need different names for all the rings.)
Remember to press Run, OK just exits the window.

Cutting the outline

Now it is time to cut out the card. What we do is that we make several rings and use the laser in several steps traveling in the z-direction on the machine to make the cut, just like we did with the hole, but now we need to make the lines outside.

Do as the picture show above.

Outside
Source should be a Layer to avoid problems in case you by misstake did not select everything in the layer.
You make up the destination layer yourself. Make a good name. 
Use the layer you made the next time (So you need different names for all the rings.)
Remember to press Run, OK just exits the window.


Finnishing the board

Now your board should look something like this (the original top an bottom layer not visible):
You can see the layers you are mre or less supposed to have. Now it is time to move the layers in to the right layers before exporting the file to the machine controll software.

What we want to do now is put the layers we have made together in the final layers for the machine.

We have almost done this phase. The almost end step is to change the Boardoutline layer to CuttingOutside layer so that the laser machine can cut your PCB area from the material board.

The final step is to generate Fiducials which help the Laser machine align exactly the PCB area between Top and Bottom layer.

Observe

This is not a standard software with standard settings, any fiddeling will have consecvenses that might not be easily reversable.
