tape actually, but I've been meaning to epoxy over top and sand smooth.

Ditron DRO Sale on Ali

I like that idea. It would protect it even more. And the epoxy could be repolished in time if needed.
I assume you would want a really thin layer though cuz the design gap is pretty small as I recall.
Maybe they will set up a CHMW deal.
I believe it is Shenzhen. But that seems odd because it's at odds to low cost. Shenzhen is the highest cost area of a China. It was built specifically to outshine Hong Kong. They didn't want the English Colony to look better than mainland China so Shenzhen was built specifically to make Hong Kong look poor. I think I kept some packing. I'll take a look tomorrow - I might even have an address. I'd love to hear a report after a visit to compare the image in my mind with what it really looks like.
Would it be dumb to try and sell the Mitutoyo scales and just buy the complete Ditron package you posted?
I tried to see if there are any clones for the KA-200 but can't find any, and the retail price of that Mitutoyo reader is $1000 by itself...

yep just a very thin layer.
no it would be very wise.
I was going to suggest just dumping the old scales, then you have no worries about compatibility, or wiring connections etc
Some on here would prolly say yes, but not me. I was being serious. Dump them. Maybe you can even sell them! Regardless, it will cost you more to make them work. Beyond that, magnetic scales have so many advantages...... Not the least of which is size.
Edit - I see @TorontoBuilder said basically the same thing.
The package I posted was just a starting point to negotiate from. Not saying that you should pay more, just get more for the same money.
@Susquatch, Always an experience over there. Shenzhen can not be beat for the electronics. Beijing is the place you want to be for "shopping".
It's changing over there so fast. At the end of the day now in Shenzhen you can not hear yourself think because of the sound from the packaging tape guns. Everything getting ready to be shipped out. Daily. It is just amazing the logistics in play. Street corners stacked so high in packages. It was never like that. The internet has changed the world.

Did you get this on Aliex? I went looking yesterday after you linked that 3 axis, 1 micron unit, couldn't find one.

we've been in one of those back rooms in Shanghai, similar products. quite the experience. OTOH they had a building full of knives and scissors, excellent quality and price. Another just chop sticks. Multi stories.
Wish I could go back.
What do you mean by caps here? It's been years since I've thought about metalworking and mills...
I just measured my travels but because the head is off and there's stuff all around, I can only get the 16" vertical knee and 12" depth travel measurements.
I looked it up, and they come 36, 42, and 49" long but mine is 48". Unless the extra ends on the side is adding to that extra 1" i'm not measuring.
Anyway to determine the travel with the power feed? Looking at this listing at this listing for 48" table lists a 36" travel. Is it safe to just provide these numbers to AX seller?

just tell them the measurements I gave you. trust me
The end caps are the brackets that the aluminum scale is fastened to the machine with.
Your numbers seem different compared to my travels? You have 450mm (~17.7") Z travel but mine measured only 16". I also have a 48" table compared to your 42"?

yeah sorry I missed that you had 48" table
so you need one scale longer than the 900mm
your travel may be less but the longer scale will fit on the mill. They dont charge more for a longer scale, and you have a buffer.
Yes, I did.
Ali is a Wierd place. The 4 + rpm is on the page I linked. It's just a different colour!
As others have said, just order them long. They are dirt easy to shorten. It's just a magnetic tape inside. Nothing to break. Take a cap off, pull the stainless shield, then stick em in a chop saw and go. Or a hack saw, or table saw, or or or. Just put the blade on backwards. Cut it like any aluminium extrusion. Then snip the stainless shield with tin snips or a scissors, move the end cap to the new location. Dirt simple.
There is a good video on DRO PROS.
Very small, very compact, dirt resistant, very accurate. I never did put big shields on mine. I just blow them off when I am done the job along with everything else. They can attract a little steel swarf, but the magnet is weak and they blow right off. The wipers on the read heads work real well.
Oh ya, stick the brackets they give you in your stock drawer for another job and make your own custom brackets. See my DRO install above.
Will follow @TorontoBuilder's numbers but ask for 1000mm travel length since that is their max.
There's a $55 coupon and with my saved coins comes out to $475 before being dinged by duty at the door!

"Duty" was a very small component in my recent purchase ($5 on $525 purchase). You will, however, almost certainly be charged HST (13%) plus brokerage. The brokerage is often where we get raked over the coals. Some couriers slap on outlandish charges (which themselves are subject to HST).
Others have pointed out that you can insist to the courier that you will handle customs clearance yourself. In that case, you probably have to go to a customs office and submit a bit of paperwork. In my recent case, the charge wasn't horrific so I just paid it. The tracking info I got indicated the amount that the courier was going to charge and I had the option to pay it online rather than at the door.
