What should the step down be for hard wood like maple or walnut when using the rotary module and included vcarve bit?

The step down value should be no more than the radius of the material.

Normally, we will set the radius as the step down value.
You should pay attention to the working speed with different material.

Best regards

In Luban when you hover your cursor over the “Step Down” box it shows the info below:

This corresponds with the proper definition of step-down as used by every other cnc/cam program: how deep each pass will lower or carve into the material. With the power and speed of the SM spindle that usually ends up being somewhere between .5mm to 2mm at the most with hardwood. (generally the rule is to use half the diameter of the bit for step-down)
Perhaps it’s different with how Luban and the 4th axis handles it but a step-down equal to the radius of the work material seems pretty extreme. If I put that as my step-down in any other program the head would either be bogging down and unable to cut or I’d be snapping bits.
Is there something I’m missing here?

As you can see in this video, the CNC bit will cut through the material and them move to next layer. The definition of “Step Down” is the depth of each layer when you 4 axis mode.

I believe you’re incorrectly using the term “step-down” and this is causing confusion for a lot of people.
It should be referred to as either “depth of cut” or “cutting depth”.

Sorry that I cannot explain it clearly. You can see that the CNC cutter will move in one direction, and it will cut the material according to the G-code file.

We call it “One cut to the end”, which means the step-down means the largest depth the bit would cut instead of depth of every step.

The words may be misleading and I will ask our software developer to consider it again.
