Calibration

[zephyr36]

I have the TouchDRO BlueTooth Adapter Board for iGaging Scales, and have used the instructions on the site for same to the best I can. I am using the "Chinese knock off" scales. they have worked on their own on my HF mill. I cannot get them calibrated. I've tried multiple times, and the closest I got the "X" axis was 3.199. It doesn't seem to be able to stay zeroed out.. I've tested it multiple times on a 1 2 3 block and it has never said it was 3". I'm really disappointed, and have pretty much given up on it. I use it because I cut the the wires on the original gauges. But I don't trust it to give me any kind of accuracy. I am using a 7" Fire (5th generation tablet, I think it was one that was recommended. I know this is long and I probably didn't add pertinent info. But can I get some help to find a starting place. I'm waiting for comments, questions . . . what ever. Thanks, Pierre

PS The Calibrations I ran today gave me: 2561_ 2.8268, Yuriy's suggestion: 2560- 2.8278, Back to actual: 2563- 3.1591, 2562-3.1610, 2563- 3.1624.

Pierre,
Are you seeing this with all scales on all inputs? What power supply are you using? Something is seriously messed up with your setup. Each tick of iGaging scale should give you about 0.0004"; your reading are all over the place. 
Your "Chinese Knockoff" scales are made in the same factory as the iGaging scales. iGaigng sells re-badged Shahe scales, so that should not be a problem. How many wires do you have?

Yuriy; 
When I originally set the DRO up I tried to cal. all the scales, I really didn't have any success. So I pretty much stayed with the X 'til I could get it figured out to what I was doing wrong. 
 
Until today I was using the power from the mill itself, but I have changed that to a computer power supply using the 12VDC. Here are those readings now: 2562- 2.5636, 2561- 2.5392, 2561-2.5313, 2561- 2.5471.  

When you asked about how many wires, I'm confused, to the board I have the 3 Cables from the scales. and the power feed. I tried to get the tach working, but had no luck with that, so I'm using it as a stand alone for now.

The board is installed in the compartment at the back of the mill. 

Thanks, Pierre

Pierre,
Some cables have 4 wires, some have 5. I was trying to see if your had 5 wires. 
So, did you try Y or Z inputs?

I tried the other axes, on the Y- 2561 for 4 readings, but the numbers I got were:2.8738, 2.8793, 2.3307, the last was 1361, but for some reason the DRO got disconnected.

For the Z reading I got 2, but I read that a DTI, if the poinrter is set at a large angle they lose accuracy. here they are: 2565-1.5641, 2563-1.4094. About now my frustration level is topping out. Any Suggestion?

Pierre,
I can't think of anything. I test every board that leaves my house and based on the ones that failed the test, the board has two failure modes: nothing happens (blown power supply) or readings are all over the place (blown IO pin). 
Scale/noise problems either manifest themselves as position creep or random resets.
I haven't seen the readings being a bit off like it is in your case. It seems to be miss-reading the first few bits of the data stream (least significant numbers) but I can't think of a reason it could be happening.
If you'd be willing to ship one of the scales to me I can troubleshoot the setup for you. If it's a bad board, I will refund your shipping cost; otherwise at least we'll know what's happening and can go from there.
Thank you

Yuriy;
I have no problem with sending you a scale. Is there a specific one you had in mind? I was thinking of the Z, because those were the weirdest readings to me. But that might not indicate anything. I do appreciate your help though. Send me your address and I'll send one of to you.

I was planning on getting the shielded cables, but was kind of waiting to see if I started getting some decent readings.

Anyway, thanks for the help, Pierre
