I do notice that the VF-3 has a 4-Axis configuration, which may be a better option (Is a 4th axis worth it, or is it just a fun toy? Also, is it a 4th axis TABLE, or is it just the drive and controls for a table to be installed there?)

The VF-3 has 1MB of program memory, is this enough for most runs? What does 1MB of program memory look like? (I just don't want to get a 1MB memory unit then later find out that it's not enough for some projects)

And lastly, what's the chip removal procedure for a CNC like that? (It doesn't have an automatic chip removal by the looks of it.)

(These are all configurable options, so I was wondering if they should be added or not)

Then for the coolant

How should we order it? I know they sell 55 gallon drums and 5 gallon buckets.

What's the procedure for dilution? Is the coolant sold in 100% strength, then needs to be diluted to 10%?

Does the coolant tank need to stay above a certain level, or can we just dump 30 gallons in there and simply keep it above 15-20 gallons (55 gallons of coolant is a lot)? (If my memory serves me correctly, a CNC coolant is fed by a pump at the bottom of the reservoir)
