bad finish milling wood

In my part of the world MDF and LDF does not look like that (US). I just looked at my LDF spoiler board which has relatively crisp tool marks. I have seen some sound proofing (?) panels that were extra fibrous. Try a different material. Urethane sign boards work great depending on density and type.

I think the picture makes it look much uglier than what it is.

I have the same toolpath file milled in another machine awhile back and that piece looks quite impressive.

I forgot what parameters I used for it. But after reading some posts here I looked at that piece again and found the bit strokes also visible. But they were so fine that I could not see them without my glasses.

So I concluded that the step-over must have been way much less than what I used for the part in the photo above.

I am planning to use some hard wood. This mdf is only for building experiance as the diy machine I am using have maybe no more than 10 hours of operation.


Many thanks to you all

Just curious what software are you using to generate your tool paths?

Raster 3-d relief milling is always going to have some ridge lines like that. It is the nature of the beast. Reducing the step over distance will make them smaller but they will never go away completely.

yes the smaller step over fixed the issue

I went from 30% down to 10% (of the bit diameter which is 3 mm)

Perfect result. I can not see any lines even with eye glasses.

The photo was taken in a hury without even blowing dust because I will be engaged for few days and I wanted to report the result before I go.

Thank you all

Philip


EDIT: for some reason the photo is not showing

I could not add the photo in the last post
never mind the mess on the edges that will be another task. I am focusing now on the finish of the head only. I will make a 2.5d picture frame and use some hard wood.
