Ditron DRO Sale on Ali

You and @TorontoBuilder listed 4 axis numbers with the quill. How does that work with a 3-axis setup?

It doesn't. You have to buy a 4 axis unit. You can get that with or without RPM.

When you buy 4 axis, Ditron (and several other makers including Touch) provide a feature where you can program the display box to add or subtract two of them. In my case, I add the 3 & 4th axis (Knee and Quill) to get a resultant Z. Because it has 4 lines on the display, I can also choose to display one of them all the time. So I chose quill & total.

With a 3 axis unit, you have to chose either quill or knee, and you cannot add them.

Buy the 4 axis version, and get the rpm if you plan to calculate feed rates accurately, and if you plan to drill many repetitive holes to precise depths. It is more refined than the normal depth stop. That and the cost to add those features is peanuts up front, but the cost to change is a whole new DRO computer
 
Gonna give a plug for Yuri's Toys TouchDRO plus a cheap tablet.
The interface can be as simple as the LCD versions, but it really shines on retained measurements, circle and grid layouts, and various "getting close" alarms.
Plus it's about $300 all-in for the Bluetooth box that sits on the machine and cheap tablet, taxes in and shipped ($184 for the very easy kit, plus $80 for a 7" tablet.)
I have the Bluetooth heads on both my lathe and mill and (for now) share the tablet between them.

I'll add to this and say that magnetic read heads are less than 50 bucks each on ali right now, and magnetic tape is 25 bucks a meter when you buy 3 meters.

Add touch DRO and you're laughing. I'm thinking of going this route for the surface grinder and another axis on my lathe tailstock

FYI I don't seem to see the 4 axis option in your link. The one I found from their store also isn't the 1 micron version.

I'll post a new for you in a second. Watch this post for an edit

Edit - here is the 4 axis with RPM.

BUT THIS ISN'T WHAT YOU WANT!!

What you want is the system in my first link. Then you want to start a chat with Ditron and ask about an upgrade to 4 axis, then ask about magnetic, then ask about RPM. You need to start a negotiation. This much easier to do bottom up than top down.

They will send you links to what you really want and can extend special pricing. This might mean you have to order something you don't want but what you do want will be in the box with three benefits. A lower price, a lower tax base, and a better system for less.
