Butcher block table, engraved steel drawers

Post by precisionbee »

I have used Aspire for a lot of different things, and this is not the first time I used it to program engraved projects, but this was the most complicated!
I did all the metal work for this table, as well as repair to the butcher block (it was trying to turn back into a pile of separate sticks).
The family crest is 1.3 MILLION lines of gcode!
Saving the Aspire file towards the end took 30 minutes, which uh...made me a bit nervous, but I am SUPER pleased how well Apsire worked out for this project.
The pictures do not do it justice, that shiny engraving really pops out on the black/gray patina of the steel. Customers were really happy with the results.

What bits, settings, and toolpath did you use for engraving the steel?

I used this engraver/holder and the bit that came with it:
http://www.2linc.com/engraving_mini.htm
I use the 0.5 inch shaft version.
This engraver is spring loaded, so travels over the variations in sheet metal flatness.
There are various bits, ball-nose, 60 deg V, 90 deg V, etc., and I have had better luck with their "Tough Tip" bits, they do last longer.

Speeds, as slow as my router will go, which is labeled on the router as "10,000" RPM, which faster than the RPM limit of the engraver...but it works. Don't do as I do, read the engraver instructions, be careful!
Feeds, 35 IPM.
I pre-load the spring in the engraver by ~0.150-0.250 inch, depending on how deep I want it to engrave.

The toolpath I used is the "quick engrave, outline".

Is it different, but most spring loaded tools do not require you to turn on the router. It is normally off.
