Yes! You can also do engrave, which will follow the line.
As for the paint, it does look good. When you do want the better contrast, clear coat it then paint, then sand. The clear stops the paint from soaking in so far and makes sanding easier. Then clear coat again.

Engrave which line or all?June 3, 2018 at 6:03 pm #61012
It’s just another option for this sort of thing.June 11, 2018 at 10:21 am #61471
Pretty sure your Zsteps should bee 400 not 300.
I may need to change my steps to 400? I cut this sleep block but the letters are only 3 mm deep when they should be 6 mm.

I’m not 100% on your parts to give you an exact number.
But to go twice as far you need to double the steps. While you are at it measure all three axis to make sure they are moving correctly.June 11, 2018 at 7:05 pm #61499
X and Y move 50mm like they should. Z however moves 25mm when I try to move it 50mm.

800 steps/mm seems to be the correct number.June 11, 2018 at 7:53 pm #61502
Yes, 400 is for the 16th stepping Rambo. Sorry about that, I should have caught it.June 11, 2018 at 8:28 pm #61506
Here is 3mm for real this time…

You need some Vbits, they are perfect for that. You have had a bit of a rocky start but you are progressing fast now. The machine seems to be spot on now, what’s next?June 12, 2018 at 7:41 pm #61568

Would I use the 1/8″ end mill on this?June 12, 2018 at 8:56 pm #61575
Yes, 1/8″ single flute is the easiest for that sort of thing (most things).June 12, 2018 at 9:10 pm #61585
I got a few pieces cut out. I was trying to print one larger piece but the dewalt kept sinking the bit in the board so I decided to call it a night.

Well those pieces look pretty good at least.June 15, 2018 at 11:15 am #61681
If by sinking the bit in the board you mean random Z movements that aren’t in the code check your speeds. Any Z speed that’s too high will cause those types of issues, and often the defaults are too high.June 15, 2018 at 1:20 pm #61682

I forgot to zero the axis before starting the cut. It worked fine the next day.June 17, 2018 at 6:59 pm #61813
Almost there…. awe crap the end mill bit wasn’t quite long enough to cut the heart out. I had the bit pushed up into the Dewalt too far. Doh!!!!

I could probably speed things up a bit don’t you think?
What should adjust?
Attachments:June 17, 2018 at 7:08 pm #61819
Not moving faster but deeper per cut (which is much faster than moving faster), go to 2mm then try 3mm. See what works for you. For slotting 5mm is about as far as you can go and still get the chips out per pass. Pocketing can usually go much deeper when using peel.
That looks like a great project to cut a few times and change the settings to get a feel for it.
Try giving it a quick thin clear coat before painting it, it prevents the paint from soaking into the tiny cracks. Way less sanding.June 17, 2018 at 7:12 pm #61820
Probably keep the feeds the same, but do 2 or 3 millimeter depth of cuts. You kind of have to adjust for what you’re cutting.
Hah! Ryan ninja’d me.

Great minds….June 17, 2018 at 10:00 pm #61831
2mm depth and much faster. 🙂
Attachments:June 17, 2018 at 10:11 pm #61833
That looks great!
Do you think you can do 3 or 4? I think 3-4 for slotting is pretty safe. Those pockets should easily be handled at full depth.June 25, 2018 at 11:48 pm #62343
