OfflineUnderstood. Thanks for your replies. I think I'll order a 24" and cut it down.
One other question. I had the opportunity to visit Jim's shop and he had a nice DRO display that he plugged the gages into (rather than using the original displays).
Do these gages allow for that or are you stuck using the dinky stock displays?

OfflineYou know when I was surfing around researching into these I did find an image of a display with three LCD screens in it. I've not been able to find it since, but there's something out there. If you're referring to an LED display then I'd love to know more.
In amongst that surfing I came across comments about hacking the displays, and it was suggested that the protocol used was not a usual one, making connection to regular DRO's troublesome. It seems that a mini USB style plug was used for convenience as a connector, it's not USB operation.
Replacing individual LCD displays with readouts in one box would not be worthwhile in itself I think, but if there's other operating advantages like the functions a 'proper' DRO would have then a different story.
Can you find out more Tyler?

OfflineTyler and Jerry, FYI, the Shumatech DRO (which is what I have) displays will accept a wide variety of scales. Glass, capacitive, or magnetic, the key factor is the output format. As I recall from other posts on the Shumatech group a number of people have connected IGaging scales. The nice thing about the DRO display is it just looks for an output pulse of a particular format and uses this to keep track of where your absolute or relative position is.
The built in processor provides a wide variety of other functionality such as converting bolt hole patterns to xy coordinates. The hardest part is a good mounting of the scales, once that is done then using the scale output generate other useful functions becomes easy. The list of useful functions available on a good DRO is long and very useful. Once you use a DRO there is no going back, it is like having a variable speed motor on your lathe or mill, it becomes the only acceptable solution.

OfflineSadly the UK presence of Shumatec stuff is really rather sketchy. The UK agents web site is poorly laid out, seemingly outdated (it doesn't even mention the 375, the 550 bits are mostly 'no longer available'), and it gives the impression that you knew what you're talking about before going there. I don't get that, surely a product aimed at DIY'ers would be better taking a measured approach to the information there. Really, it's rubbish. The Shumatec prime site has gaps too, but at least it's from this century. If Shumatec want a caring distributor in the UK ask them to contact me!
Sorry, it all seems like to much fuss to get them in place over here, and with ready to rock assembled display units available for less money and far less hassle it's only the scale sourcing that's an advantage with them. After that much procurement and assembly work the perception of 'value' shifts significantly for me.
What's needed to enhance this cheap iGaging system IMHO is a simple display alternate which just uses a mains power supply, and the three displays but in LED's, same facilities. Keep it on the side of low cost and don't lose sight of what it's like without having any DRO at all.

OfflineHi Jerry, you misunderstood my post. Shumatech is a US company run as a hobby by an engineer name Scott Schumate. His web site is at shumatech.com, it is an excellent web site. He has developed and sold, at cost, three versions of his DRO. The first was the 350, followed by the 550 and soon a 375. They come as kits that are easy to assemble and have been priced at very low prices when compared to the commercial units. The site you went to is the European distributor. I have three of Scott's units and would not trade them for any unit on the market. They will accept just about any scale you have which is not an option for the commercial units.
Scott's biggest problem is the popularity of the product, the poor guy gets no rest and is constantly being hounded for more units. Putting together the component buys and kitting is a huge undertaking. The last order for the 550 was in the hundreds of units, try doing that in your dining room. The software is open source which allows some of those that enjoy adding features to be able to get the source code. Scott has been more than generous with his time and experience.

OfflineJim, I can assure I've not misunderstood. I understand the origin and respect that and the individual behind it, but in essence according to the distributor in the UK none of it is available any more, not that it's out of stock, that it's simply not available period. To buy a full kit from USA once import taxed and delivered costs twice the price of an alternate assembled DRO display from a UK provider who always has them coupled with good support, as I said it's only that scale type that remain an advantage.
You must be seeing something different to me on the schumatec.com site. If I click on the shop and then to the 375 the only thing I can buy is a printed front panel. The 550 section lists more parts but all but the printed displays are out of stock, always have been for me.
So whilst I get the manufacturing output bit and sympathise with and respect the origin etc is it simply not a happening thing over here as detailed above, it costs too much and doesn't actually seem to be available reliably here.

OfflineHere's an alternative approach to achieving better low cost displays using Chinese callipers for scales, if you happen you have an old pc kicking around (who doesn't?
)
http://www.caliper2pc.de/en_index.html
I've downloaded the free software and it's a superb visual display of information, highly customisable. To play with it virtual scales can be used to get to know it without spending a penny on the hardware.

OfflineHi Jerry, I did not realize that you are in the UK, that explains why you went to Lester's site. Sorry, my error. There are some Shumatec's on the used market but they go quickly. The next major opportunity will be the 375 which will be open for orders in the not too distant future. I have no alternative recommendation to your import tax.
