Hi guys,
my Mazak is not running yet but I keep moving on with that bugger. No more parity alarm. Parameters are not perfect but acceptable. I'm having chuck and tail-stock barrier alarms. Must be something wrong in the parameters but I can live with this. The bug of the day is #14 Drive alarm Z axis. I have checked LS, turn the ballscrew by hand(well not really by hand, that carriage is a monster!). From a mechanical point of view, everything looks fine. I tried to unplug the Z axis resolver and got a No signal alarm instead of Drive alarm Z axis. Could it be the resolver? I also tried to swap X and Z resolver on the board and still got that Drive alarm Z axis. Any clue on this one?

P.S. Maybe I should have put this in a new post?
I answered the Z-axis fault in your new post. Better seen there when people do a search.
BTW, your thread titles are very specific and that is why you got the help so quickly.
The barriers are a wonderful thing. Adjust and use them properly and they will save you from smacking the tailstock as there is not much room to be had. Avoid the urge to hit barrier cancel. The turret sheetmetal on my machine was beat to shit before I got it. Pushing barrier cancel will let that happen quite easily.
The chuck and Z axis barriers are edited on the command page. The tailstock barrier is located in the upper right hand corner of screen where it shows distance to tailstock.
The major shape of the tools, chuck, and tailstock are in the parameters you reloaded.
Go to Trace screen, zoom out by pushing 'scale' soft key, type in 20, then input. You should now see the chuck, turret and the tailstock in the screen. Push the "store' soft key to keep this view and this scale.
Make adjustment to distance to tailstock (TS distance?) on the command screen, then go back to the trace screen and the tailstock will move on the screen. IIRC, mine is somewhere around 30", but adjust the number until the turret hits the barrier about 1/2" before it contacts the sheetmetal.
One more thing, you have a MAXIMUM Z tool length on your 10N ATC/MC due to the way it indexes tools and such. Magic number-- 9.225" total length from the tip of the tool to the back of the VDI flange. On boring bars, this works out to be a 5.100" tool projection from the face of the boring bar holder. Forget to heed that number and your turret will bind up or snap off small drills when you index tools. BTDT more than once.
