Oh, and replacing the ball screws, fun fun At least it's got a cartridge spindle so when it comes time for that it wont be a giant pain........ Well, it's still going to be a pain in the wallet. If it's a really high time machine, getting the taper reground is nice.........
Actually the ballscrews are not much of a problem especially the Z. Not as expensive as I feared either when using reground and ceramic balls. I had to buy a new extended Z tho and that cost more than the X &Y combined. .So far the spindle seems OK. Need to actually check it out tho. Regardless I'll do whatever it needs.MasterUsing a good blue die cream smear it all over one of the better tools and plug it into the spindle. Be sure to coat the complete taper. Take it out and look at the pattern that it leaves. if the pattern is the same all the way around the taper and there is no real big dead spots like there was no contack then it is good to go. I have the name of a Kansas City company that will come out and grind the spindle right on the machine. They set up a small grinder on the table and plug in a program into the machine that brings the Z down and interpolates the XY to grind the taper. Cost was $1300.00 US when I had my VFO done in 2005. Should have about 700 PSI pressure holding the tool in also.If you don't then you will need a new CU washer pack. Not bad to install. My machine tec calls them doors Man Traps. Lose them.

Yes,the prussian blue is coming out tonight. A man named Ken Houk with Open Source CNC from Wichita has been a big help so far. Have you heard of him? Seems pretty well versed in this stuff.I think he told me of the same person as you are about splindle taper grinding. Yeah,I agree on the man trap thing. I just want to know how they are SUPPOSED to work.
Do you have a list of the Fadal commands?
Now THIS is my sorta stuff.... good luck. Cant wait to see the stuff you got coming out of the beast.... LOVE machinery.....
