So... the dust shoe. The wish list includes:
1. Transparent top, to see what's going on.
2. Independent of spindle position
3. Have two attachments, a close-clearance air gap (no brush) for flat stock, and a brush for "lumpy stuff"
4. Have the vacuum hose attach behind the gantry for better visibility
5. Easy tool changes
6. Connects to a 2.5" hose and shop vac
7. LED light ring would be nice
I saw one design that uses a stepper motor to adjust the height. Seems like an extravagance for the coolness factor, without being significantly more useful. The rolls of tape represent a possible height for the spindle surround. The issue is that with taller cutters (think: drill bits), the Z axis has to be higher above the table. If it's too tall, it may rise above the top of the dust shoe surround, creating a big air leak. A factor contributing to this is that the spindle is currently placed so that when at cutting height, the Z carriages are centered between the X rails, minimizing deflection. A compromise is to lower the spindle just enough to increase the amount it can move without leaving the confines of the dust shoe surround.
