WeCreat camera - not able to get through calibration process with AprilTags or Circles

I’m breaking this out here as I had asked on the 1.7 RC thread but it got lost in the shuffle of the final 1.7 testing.

I’m not able to complete the camera calibration on a WeCreat Vision 40w. Same results on the final 1.7 release as I was seeing on RC-15.

When I try to do the circle pattern, I just keep getting Pattern Not Found messages.

I’m focusing the machine first before I do calibration so it lowers the camera down to the correct height for the material.

Looks like they recently posted a video specifically on setting up the WeCreat camera. Somehow I missed it until now.
