Yo yo all! Engraving metal with 3018 Prover... :oO HELP!!??

[rmuk]

Sorry to be so blunt but theirs no way to make it less painful so I'll just rip the plaster off.!! . . These machines are barely good enough to scratch let alone engrave with any precision or accuracy so don't waste time or expensive materials trying is my advise.

You have got ZERO chance of engraving anything very well with only 10,000rpm and virtually Zero chance of doing metals like Silver. You need at least 30,000rpm and Idealy 60 to 80K rpm to do the job correctly with such tiny cutters.

This is the reason why the REAL things cost so much money because low Run-out and ridgidty are key to engraving quality and this cost's.!

Thanks Jazz appreciate the guidance. I guess after I got an almost acceptable drag engraving with the Cricut I thought I should get at least the same quality result with the more robust (compared to the Cricut anyway!) 3018 cnc and some simple cutter rotation you know, to go a teensy bit deeper? https://youtu.be/QuM6Ic1Cxok This video as I mentioned above kinda gave me hope that 10k rpm might do it. False hope probs... darn.

Yes, I see these videos all the time showing weak machines cutting hard or difficult materials, and while they do cut theirs a big difference between rubbing and cutting. I could fasten a black n decker drill to any machine and cut thru 1" thick steel plate given enough time but that doesn't mean it's cutting correctly or it will do it twice or the part comes out the size or shape it's meant to be.
For instance look at the shitty finish it left and poor definition of the lines, it didn't cut as much as rub the material away. He blamed the material for being soft but with more RPM less runout and a stiffer machine, it would be a different story because he could cut faster and get a much nicer finish because the tool is being used like it's meant to be.
