3D Default "Depth per pass" -hardwood

It looks like Easel Automatic settings defaults the depth per pass to 0.0032". At the same time, Easel gives a warning about the depth being under 0.1" per pass.

With it being a 3d carve, does the Depth need to be so shallow? I know I might have to do some test cuts, but wanted to get a good starting point.

Thanks in advance

That is a great question. I noticed the same thing and automatically just changed the the value. I await someone more knowledgeable than us.

All settings provided as defaults are conservative estimates and should be adjusted by the cnc operator based on your specific setup.

This point is interesting as the depth per pass in mm is not the same (0.7mm = 0.028"), around ten times greater. In my 3d relief models with lots of deep and wide valleys I prefere normally to stick to this 0.7mm (=quarter of my bit size) or increase to 1.35mm (almost half of the bit size). But this is a consensus between having

  • 0.7mm => more roughing passes but less to be removed by the finishing pass and thus better finish quality on my point of view
  • 1.35mm => less roughing passes but more material to be removed by the finishing pass in some places

As summary Iā€™m a bit surprised by this 10 times factor between the default settings in the inch or mm worlds

I actually made a typo. The automatic default for roughing depth is 0.032", not 0.0032".

Feed 72"/min
Plunge 24"/min
40% step over

So it is closer to the default in mm.
