Hope I'm not going off topic here but when I read the subject ("Cheap Chinese Scales") I though we were going to discuss whether SINO scales (or similar) would work well with KFlop/Kanalog, or not.
I took a peek at Shumatech site and it scared me, bills of materials, DIY stuff, soldering (modifying) chinese PCB boards paying attention not to burn them, dismounting the encoders, etc.
I would stay away as much as possible from that kind of hassle and trouble... there exist already made scales (like SINO) that cost about $100, have 1 um resolution, work up to 2 meters/second speed, have a differential A _A, B _B, Z _Z output, come already wired with a metal shielded cable and should supposedly work out of the box.
I would like to know if anybody has tried these, do they work well with KFlop, are reliable, how much are they robust against electromagnetical noise ?

I'm interested seeing I'm looking for a digital scale and readout I can use on my chop saw cutting table so I can set up cut lengths quicker. Was interested in knowing what low cost Chinese scales you had found or were looking into Thanks
Was wondering if anyone has found a way of using the Cheap Chinese Scales for positional feedback either using Hardware to convert the digital output back to quadrature output or could it be done in software as an input mode. (This would be nice) Shumatech with the Open DRO project have done it here http://www.shumatech.com/web/products/opendro and the Chinese scales seem to provide output in one of 4 formats (24BIT, 21BIT, BCD7, and BIN6 protocols) Cheers

Here are a few that are cheap and would work great for a chop saw. You can find these in many different lengths. Russ 24" scale with remote readout $45.00 super cheap http://www.ebay.com/itm/24-Digital-Readout-Scale-Bridgeport-Mill-Lathe-DRO-Table-Linear-Magnetic-Remote-/370887812921?pt=BI_Heavy_Equipment_Parts&hash=item565aa2e739 16" scale with digital display $59.00 http://www.ebay.com/itm/Horizontal-Linear-Digital-Scale-400mm-16-Inch-/111110373130?pt=LH_DefaultDomain_0&hash=item19deb1bf0a From: DynoMotion@yahoogroups.com [mailto:DynoMotion@yahoogroups.com] On Behalf Of Wcarrothers Yahoo

Iam using SINO scales on my MillDrill with KFLOP closing the loop of my stepper motors.And have not had any issues.

Do you also use coolant? I mean do the SINO scales resist to coolant?
Also how did you connect them to the KFlop? Do you also have KAnalog or do you use some other circuitry?
Thank you, EC

Yup, i use flood coolant all the time. The SINO scales i got come enclosed and have another aluminum extrusion that helps to protect them.
The scales are connected to the KFLOP by a interface board i made. Before i made the board i used one from Winford Engineering. The KFLOP board uses the scales to close the loop of my stepper motors. Here is a picture of the Z axis scale on my mill. http://groups.yahoo.com/neo/groups/DynoMotion/photos/albums/176979248/lightbox/2041945399
