First engraving trials

Thanks, Toff - I have been circling around the CNCGraf for a while, not yet being courageous enough to skip my known-working S4-system.

Those Baumer My-Com switches sure are expensive (!!) but nice. Do you have any suggestion for a not-quite-so-expensive, but-relatively-precise route that I could go for testing the system irl?

I think every micro switch, which is at least of decent quality - for example a Marquardt switch - would do the trick.  I have sent a PM to keep this thread clean.

I've been playing with the mill today, a front pannel for a GSSL compresor, quite happy with the results, 1'5mm two flute bit with 0,4mm depth pass for the cuts and 0'4mm 30° for the engraving, 0'15mm depth.

It's 5050 aluminium

interesting .
Jakob , did you ever tried with the microswitches or such ?

No, I must confess that I haven't had the guts to move away from the already-working-but-very-slow system that I got...

This should work

Is it an inductive feeler?
What is the function of the black thread/screw that touches the panel?

Jakob E.

it is a  Baumer high precision limit switch ,  micron accuracy
the black thread is a safety stop to not damage the switch if something goes wrong.

Aaah..nicenicenicenice..

Approximate cost, where to get?

I still had to play with the action of the  end stop by the time I made the video but all is working excellent now.
My engravings are supper smooth.

got it from ebay , think 40 euro something. Baumer.

Then you have also Metrol.jp, they have nice models as well, but expensive

I have a spare one I can send to you if you like...
