Yet another DRO Install - King KC-20VS-2

My son and I have been enjoying the new mill and decided to install a 3-axis DRO on our new KC-20VS-2 mill. I decided to take a few pics of the install.

Fortunately there are many videos\forum posts on installing a DRO on the G0704 - this mill is almost exactly the same so I had lots of good ideas for mounting the scales.

The y-axis required the most work. I decided to fix the reader and have the scale move. The thinking being there would be less wear and tear on the cable going to reader.

I used a 12" piece of .75 x .75 square stock to mount the scale:

We had to machine the edge of the piece to clear the base:

Since nothing is square on the base, I had to shim the l-bracket.

The x-axis was much more straight forward. Only had to drill 2 house to hold the scale. I reused the existing holes in the y-axis that holds the way cover to hold a piece of l bracket to hold the reader:

Finally the z-axis was very straight forward. We had to machine out a bracket to mount the reader to the head:

Finally the DRO head unit:

We started playing around with some of the functions - pretty cool little toy! Now we need to find some projects to work on :)
 
Looks good !!
I have KC-15VS from King Canada.

Have you blown the fuse on the mill yet ?
Spoke to another owner who replaced the fuse with a circuit breaker in the first week.

Thanks Len,

So far so good - haven't blown the fuse yet. Mind you we really haven't pushed it too hard yet. Milled some mild steel the other day it is worked flawlessly.....
 
Yeah, I have been flycutting MS and using up to 5/8” endmills without any problem.

I am just getting back into machining after 30 years of mech. design and project mgt.
What brand is you DRO ?

It is the ToAuto brand from ebay.ca The ship the non-lcd versions from Markham and the LCD dro's are shipped from China. They ship with DHL so it took less than a week to arrive to Mississauga.
 
I finished my Spindle DRO Upgrade this weekend - it works way better than the stock tiny dro that came with the mill.

I mounted the cut down scale on the side, machined out a piece that replaced the stock plastic piece that was wide enough to extend past the right side and then made another piece to connect to the reader head. Note, I reconnected the stock DRO just incase I need to use the Milling Head Scale on the z-axis.

This is much easier to read that the little lcd dro - plus it is way more accurate.

If I ever need to use the DRO z-axis scale on the head - I just have to unplug the spindle scale and plug that one in.....

If i were smarter i would have ordered my mill DRO with a 4th axis so i could monitor movement of both the quill & head in the Z. Most 4 axis DRO’s (i believe) will combine the numbers for you if you wish.
I have on my to-do list the installation of an independent DRO for the quill. The one on my drill press works well, is a fairly easy install, seems pretty consistently accurate, and less than $100 for a good quality unit.
Your design / idea to have similar scales on both Z movements and just switching the plug sounds good. I may have to revise my to-do list a bit.

Yup, that was my plan from the git go. Would not have bought one that couldn't do that.

It isn't a show stopper but the cost of the 4th axis made it a no brainer.

One could always get a 4 axis Readout and just put 3 scales on it till you find the cash for the 4th scale.

Mine will add any two and still display 4. So I get total Z (knee plus quill) plus a separate display for just the quill (or just the knee). Very useful.

Nice install how did you setup your machine light?

Oh that was a small project I did last year. I had a few feet of leftover LED strip light from another project. I simply added several rows of it to a piece of acrylic and soldered all the pieces together. I bored a big hole in the center of the plastic and have a press fit on the spindle. It works pretty good - directs all the light down at the vice with little to no shadows.
