The spindle I bought was sent to the wrong address... so I might have to choose a new one and I have been offered a good deal on a new ATC spindle. The problem is that I don't fully understand how they work or what additional kit I would need to buy and the seller is completely useless.
First, is there additional hardware needed to connect the spindle to my computer? I am assuming that something is needed to allow Mach3 to operate the pneumatic tool holder? Can Mach3 or Linux CNC even operate ATC spindles natively?
Can I use my regular shop compressor (with a regulator) as the air source or would I need to buy some super expensive CNC compressor?
Do the compressors have to be on the whole time the spindle is in use or are they switched on just for tool releases? The spindle uses fan cooling so compressed air is not required for that (I think).
Can I use a bunch of those cheap plastic ISO30 tool clamps at the side of my table instead of investing in a carosel?
Do ATC spindles generally draw more power than regular spindles. It's only a 3.8kw 220v device but it states 24amps. That's 25% more than the 5.6kw MTC spindle I bought. I can't figure out why. It is a 4 pole device but I don't really know what that actually means....
