Re: Potentiall gotcha with the cheap Chinese DRO's

I guess I am trying to ask if the issue occurs at any place along the path or in one location? You can zero it anywhere and check if it provides incorrect displacement.

Double check that the read head is not loose and distance and angle with respect to the tape is within spec. If you have another piece of tape you can check the read head against it however if it is only off by 1 mm that could be hard.

I have 4 DROs (3 M503) and all have the SS tape on top of mag tape with no issues.

Hi Imran,
No the zero'd position seems to be exactly the same every time. It's either side of that point that it drifts out. I have tried using a Starret measure stix on the magnetic tape before and found the reader didn't read at all, so wondered if the metal tape was the issue.
Regards,
Bryce
