Blurry Lines and Non maintained Depth

Hi,

I've been having a problem with one particular cut. Hopefully some more experienced guys can help.

VMS-80 cutting with preview played back from a DAW.

I'm getting badly formed grooves. The centre line in particular looked jagged. The stylus was recently changed (with a new one) and I cut a blank groove. all looking good. I also re-calibrated for the new stylus length.

What else should I look for? The heating temp seems all good.

I've also had some issues with min depth not being maintained. Once it was because the lacquer wasn't flat. I know the 80 has a very stable computer but could this be caused by fast stereo transients? Sticking in an EE doesn't seem to solve this particular job.

Thanks again for your wisdom

Sounds like something broke the tip off the stylus or just a bad stylus. There have been a lot of issues lately poor quality from apollo. I started using Adamant.

No idea why it would not maintain min width...don't have a VMS80. Does it have a dash pot? If transients are causing the issue perhaps tightening the dash pot a bit would make it react a bit slower and not narrow up so fast.

Yes, I second the bad stylus batch issue...
Also, If it's a new stylus, you can give it a few hours to "Break in" and clean up.
I notice there's a typical time period between 4 and 10 hours where the bottom and sides of the groove start to clean up...
But not always...

The Transco stylus have been horrible. I've returned 5-6 of them in the last 2 months. Switched back to Adamants.
