Hello,
I have an old bridge port with a cheap DRO installed. The x-axis scale has recently stopped working, in a strange way.
This is the installed unit: Amazon.com: iMeshbean 2 Axis Digital Readout Dro for Milling Lathe Machine with Precision Linear Scale (100mm-1000mm Options),you will receive Random Two Scales (500mm and 1000mm scales), if u did't leave a Note.: Home Improvement
I've done some trouble shooting and this is what I've found:
- Doesn't matter if I plug the scale into the x or y socket on the receiving unit - the problem persists (must the the scale itself)
- I've pulled the end caps off the scale - all looks good inside. The glass is intact, no debris are visible, I tried cleaning the scale with isopropyl alcohol and a cotton swab (this didn't change the symptoms at all, but everything looks good inside)
- inspected all connections, wires, solder joints (all looks good)
The scale operates perfectly on one end, for about 10". Then it hits the "spot" and the reading just freezes and jitters back and forth plus or minus 0.0005 on the readout. The "spot" is the same every time. Every part of the scale on one side of the spot works, every part on the other side doesn't work.
Any ideas? This scale is pretty new, about a year. Has only been used a hand full of times. Worked great until it recently stopped. I've ordered a replacement, but want to know what's going on still. Could I have install the scale in some way that caused it to fail? How can I prevent this from happening again? Can it be fixed?
Thanks,
Dave
