CAM: Missing tags with specific ramp angle

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Problem description

In CAM I have found that Tags often (always?) don't appear when ramp angle set at 75 degrees. I changed to 90 degrees and problem fixed. In my case I had increased to 10 tags to see if that was a problem. I ended up with 2 vertical on left side and 2 vertical on right side. The 6 horizontal ones were missing

### Code of Conduct

No source file or test is identified. Start by reproducing the CAM setup with a 75-degree ramp angle and compare it with 90 degrees, checking the placement of all 10 tags. Done means the expected horizontal and vertical tags appear reliably at the reported angle.
