Yes that is the board I am using. One problem I have yet to find a good solution to is lifting the knife at angles greater than a set size so not to brake the blade turning in the material. A rather crude work around that I found is to make a small gap to the path at the angle changes to force it to lift. I was planning to use the M8 coolant pin to lift the knife. The gcode tools extension outputs in radians but you can set the scale to 57.2958 to change to deg, I canged the py file so it stayed in deg.
yes so without tape you could not get the wheel tread. The smoke all around it would stain it and cause it get washed out. Tape gives good contrast and protects the woods finish around the engraving. If you plan to paint it also acts as a prefab mask.
