Android tablets

Thanks Yuriy,
Heading out to shop now, will get a picture posted when I clean up the mess of tools I have laying everywhere.

Yes they are lass scales. VEVOR brand.

Also I forwarded the email I sent to your GMAIL to the touchDRO.com

I'm still getting the jumping on the readout.

I have calibrated the x axis using the 1 2 3 block method

After calibration I get.1567 on the touch dro screen only moving X .040

I only have X axis installed at this point.

Galaxy tab lite A7

TouchDRO V3

Android v12

No freeze of 0 as of yet

Hand wheel movement of X using dial verified accurate when making parts without a DRO

Pictures attached

Thanks, Joe

Joe,
For the pins (thank you for re-sending the email), you need a "D-Sub Pin remover", something like this: https://amzn.to/3HECk0k. They are pretty fiddly, and I don't know how they will work for removal of the square pins.

For calibration, did you zero out the readout before checking the calibration? After you change the CPI, the reading will be non-sensical. Did you follow this page: TouchDRO Input Calibration. There is a possibility that you connected the "R" line to "A" or "B" input, which will mess with the scale resolution, but the calibration would still work. The result would be very low scale resolution, not random numbers.

The jumping problem I can't explain (or wrap my brain around). iGaging scales do it because the bit in the middle is flipped randomly. With their resolution it just happens to be 0.200". Glass scales output pulses that TouchDRO counts (5-micron scales would output 5080 pulses per inch). There is no mechanism for TouchDRO to go "oh, this time I will randomly count 1020 pulses instead of 1".

Regards
Yuriy

Thanks Yuriy,
The jumping problem was the Samsung tablet, shouldn't have even messed with it after reading your information, I just watched the YouTube calibration video and am pretty sure I wasn't doing it correctly. But the Samsung was definitely jumping/skipping.

Have an ONN now and will try calibration again tomorrow with it. I will report back.

By the way my Grizzly mill is a full size Bridgeport clone. The dial graduations are .200 per turn.

thanks, Joe

Yuriy,
I got the ONN tablet setup and working fine.
The Samsung that I bought almost a year ago was the problem. Android 12 apparently automatic update without me knowing, lesson learned.

Thanks for the help!


My apologies to old Seabee for cluttering up his original post,

Joe, I don't mind at all. This is how we All Learn. My glass scales came in awhile back and I have not had the time to even open and check for damage. My wife spent a week at our local hospital and now she is in a skilled nursing and rehab center. So I have been busy. It seems that I forgot the 6 "P's and now it's bitten me. For the younger generation that's Prior Planning Prevents **** Poor Performance. I have a placement problem with my mill and have to move it about 3 Inches to allow a 18 inch shelf system to be placed on the wall behind it. That shelf will hold the 5,000 watt transformer to supply 230 v ac to the Baldor controller that converts it to 180 volt DC to power the new 1hp DC motor I now have e installed. I can't wait to get it all hooked up and running.
