I love my quill. Wouldn't be without it.
Get near job. Move head down close to job.
Last bit of Z move with the quill to touch cutter on job.
Zero the DTI on mill, DRO z on Mach3. Lock quill.
If on hard material move the quill up a bit.
Move the head up. All done without a resetter, in 10-15 seconds.
Move quill back to zero on DTI.
Using other machines, without a quill setting Z zero is a pain.
Super X3. 3600rpm. Sheridan 6"x24" Lathe + more. Three ways to fix things: The right way, the other way, and maybe your way, which is possibly a faster wrong way.
