Is the material a uniform thickness? How are you determining the Z zero point? Is your spoil board surfaced and parallel to the gantry?
I do it by sound. When I am slotting or profile cutting in wood I keep my speed at about 2500mm/min depth is 1/2 the endmill diameter. If the...

Is this a CNC machine using grbl to make precise moves, or do you just want to move it manually?
That is easy. Just put two holes in your drawing. If using Vectric software place these wholes on both layers of the drawing. On the first side,...
