OK, take it easy on me....this is the first thing I have done.

Can you post the .cb file too?

It won't allow me to attach .cb files

We are also in the process of cutting hardened steel rotary die. Smallest cutter is however  0.1mm, also V-Bit carbide and I see it broke this morning, bleh. Will just have to try again a bit slower.. It's being cut on a HAAS Mini-mill with 6000rpm spindle..  Good luck with your job, you going to need it;)

I'm trying to engrave an Uzi bolt and have had a little luck with a spare one I had laying around, but now that I'm actually ready to engrave my info on it, the program isn't cooperating. I feel like a clown.

OK, does this look correct as far as the sizing if I wanted the letters to be 3/16" tall? I can't upload the Cambam file, otherwise I would.

You may have to 'zip' the file up first in order to post it here. You can also send it to me by email. If you have a scrap piece of material laying around that you can send to me I'll try and figure out what settings you need to make it work.

Another thing that hepls is to RAMP the bit into the metal in lue of a straight plunge cut. Also set the feedrate based on spindle speed. Slow spindle slow feed. Coolant helps with hard material. But if you use coolant make it a constant flow. Thermal shock can damage the fagile tip.

Just a thought, (;-) TP

Let's see if this works...

Did anybody have any luck opening the file?
