Is that a question, or a statement?

If you want to always use the Z Home position as the Z Reference position: 0) Power up the machine and control, and let it home itself as usual. 1) Move the head to home by pressing Tool Check. 2) Go to the Tool Offset Library (F1/Setup -> F2/Tools -> F1/Offsets) 3) Press F1 to set Z Reference 4) Pr...

Regarding your "move to home" question: Programs normally do an "M25" or "G91 G28 Z0" move at the start of the program, at every tool change, and at the end of the program. Those moves take Z to the previously-found-and-set Z home position. They do not search for your s...

... then waits for the turret to unlock and for the target position to come around; then fires the "stop" solenoid for the turret; then waits briefly; then turns off the index solenoid for the turret; then waits for the turret to lock back down; then turns off the stop solenoid.

Tool measurement and Z part setup will work just fine with a Reference Tool, and it will work just fine with Z Reference set at Z Home. If you are setting part zero using a measured tool, and you have measured the tool before setting part zero, then it will work just fine. Note that setting P3 = 2 d...

Most or all of those functions can be provided with the Centroid jog panel keys.

The "Aux" keys in the upper right can be custom-printed as needed; or if you opt to just use the "virtual control panel" on a computer monitor, then you can customize the graphics yourself.

If the problem comes and goes without your having changed the part program, or the tool offsets, or the part zero location, then it is probably not related to your part programming or job setup procedures. And no, you don't have to use a new and different WCS for every job you run. If the problem co...

Got to assume that whole strip of Mylar crap switches goes away with the conversion. You've lost me here. Are you referring to the turret position encoder? Or to the switches such as the X limits, spindle lockpin sensor, cutoff slide up/down, etc.? Or something else, maybe inside the old control ca...

The CNC programs looked fine to me. G43 height compensation was activated, with H numbers matching the tool numbers. Initial Z rapid-down moves go to +0.100. Subsequent Z moves feed to -0.100, or -0.250, or -0.375. Next time the problem happens, or is about to happen (based on the DRO numbers), get ...

The noise is from the portable air compressor. I doubt you could hear the spindle bearings over it, even if they were bad...

Yes, a retrofit control based on an Allin1DC would easily fit in the ca. 30" x 60" cabinet on the back of the headstock.
