Would a profile exist for the Ace Pro?

You can take a calibration video like https://download.actionstitch.com/calibration_sample.mp4 and send the video to me.

For the checkerboard, you can pick one from Calibration Checkerboard Collection | Mark Hedley Jones and show it on a big screen monitor or TV.

Try to save the following to a json file and then click the ‘load from file’ button when selecting the camera model:

However, the calibration error appears to be somewhat high, possibly due to the checkerboard paper not being completely flat. If it does not give you good stitching, taping down the paper and ensuring it is completely flat. Or show the checkerboard on a large screen as I suggested.

I tried again using the laptop screen. Hopefully this one is better:

This one is definitely better:
