Thanks for the information. It really looked like you were taking much deeper cuts! But still impressive with the DOC and speed.
I love the Taig machine. I just got a new Gecko 540 to replace a Xylotex system that could never work with my system. I have 286 OZ Keling motors and I could not get the XYLOTEX to cut! Lost steps, no increase on speed, and no cutting of parts. It was eventually refunded (The seller was a good guys and helped me with my troubles). I went back to my old system and used it for a few months. I now have a working Gecko 540. I got my TAig today to accidentally rapid at over 100 Ipm. That is way to fast for a machine without linear rails or ballscrews. But let me tell you, the 540 spun the suckers and with huge amounts of power. I have lowered the system to 20 IPM which will be my cutting speeds.
I do not cut steal, I will actually be cutting some tomorrow because I need to make "Panel openings" for my electrical enclosure, the front panel will house the Gecko540, E-Stop, Switches and plugs. Should be really nice!
I do however cut aluminum on this machine and you will see some amazing parts made from this machine in the coming weeks, you won't believe it came from a Taig.
As far as getting coolant going, you will need to use a relay board. If you buy a Break Out Board that has some outputs, you can easily wire a relay board for the coolant. I did that until my BOB went up in flames (Board was defective) But will now be installing a relay on the Gecko540.
I will probably build my own Mill as well. At least I think mainly because, I can. And it would be lots of fun. We'll see though.
It would be easy to strip the Spindle head maybe if you had a sandblaster and you can somehow protect the inside of the spindle bearing holes. But your already stripped it.
