ELEKTOR FORUMS

Hi Francisco,

just a suggestion:

1. Load your source-file in colidrive and place it where you want to mill or drill, don't forget to "ground".

2. Search for a pad in upper right corner and center the cursor using high zoom-value. Move Profiler to this point.

3. Position your pcb in a suitable way, that you can drill a single hole into the corresponding pad. Be sure, it's the right one!
Drill must be deep enought (some mm into mdf-plate)

4. Put a suitable pin into this hole, so you can rotate your pcb around this first point.

5. Search for a second pad in the lower left corner of your file and move Profiler to this point.

6. Now you can turn your pcb until the second hole can be drilled.

7. Fix your pcb with some sticky tape.

Your pcb is now synchronized with your file.

Excuse if there are some linguistic defects, English isn't my native language too.

Greetings

the second reference point is always slightly out of line

... happens, if the film is made by laserprinter or copymachine.
These units must be calibrated before.

Peter

... make a simple test, if not already done:

Program a big rectangle (20 x 28 cm) with AutoCad or something similar and draw it with your inkjet. I had some differences!

Peter

the precision used in the conversion of the Excellon coliliner is 3.3

3.3 % or 3.3 mm or what else ??

Peter

Thanks, I did understand now.

My coliliner had 2.4 preadjusted both excellon and gerber.
