Do I need to adjust the Qinux Gravizer for different materials?

Swapping the tip matters less than how much pressure you use. I pressed too hard on a metal tag and the tip just skated and dulled. Light passes, let the tool do the work.

I mostly go by feel and sound rather than some setting chart. On glass I switch to the finer tip since it bites less, but on metal I honestly don’t change much besides going slower. The manual being thin on this stuff is pretty normal for these pens.

Different materials definitely change how it feels, but I never got much out of trying to follow a settings chart or anything like that. What I noticed after a couple weeks is that the battery level actually messes with the behavior more than people mention. When it’s fully charged, the tip bites a lot harder and leaves deeper marks. Once it drops to maybe half, the same pressure barely scratches the surface, so I end up pressing harder without realizing it and the lines get sloppy.

That threw me off at first because I kept thinking it was the material or the tip causing inconsistent results. Turned out I was just comparing a fresh charge to a tired one. So now I try to do the delicate stuff earlier in a session and save rougher work for later when the power tapers off. Sounds backwards but it works for me.

On the harder surfaces I also noticed the tool gets warmer in the hand after a while, which makes it a bit less steady. Doesn’t happen on softer stuff nearly as much. Not a big deal, just something nobody warned me about. The manual really doesn’t cover any of this stuff, so most of it is just trial and error.

The thing I didn’t expect is how much the material changes the battery drain. On soft stuff like pine I can go for ages, but when I was messing around with a stainless water bottle it chewed through the charge way faster. So if you’re planning a longer metal session, maybe top it up first.

The tip change is the only thing I really bother with, and even that depends on how deep I want the line. On softer stuff I keep the same head for ages. Harder surfaces just eat through the tip faster, which I noticed after a couple of practice pieces on metal.

Material definitely changes things, tips alone won’t cut it.

Tips matter way more than the manual admits.

I’ve had better luck just slowing my hand down on harder stuff instead of changing how I hold the pen. For me the grip stays the same across materials, it’s the speed that makes the real difference. Tips do matter but I’ve engraved a few metal tags with the same tip I use on wood and they came out fine.

I’ve had mine for a few weeks and mostly use it on wood too, but I did try it on a metal dog tag and a glass jar. The metal one took forever and looked scratchy, but the glass actually came out cleaner than I expected, so that was a nice surprise. I didn’t change how I hold it, just went slower on the glass.
