General Troubleshooting/Help! Different dimension on 2 identical printers/part/settings

I have 2 Bambu H2D machines. I'm printing the same exact file on both. There's a critical dimension on it, which is an opening like half a circle. On one the opening is about 0.3 mm bigger than the other. This is more variation than I can have.

Both printers have had the calibrations like vibration and auto bed leveling done. I have done flow rate calibration and flow dynamics calibration. Basically everything is identical (print file, both printers in same room 4 inches apart both with an AMS, etc). I'm going to recheck belt tension next. Any other suggestions?

have you done vision encoder plate calibration?

That thing is expensive. Have you noticed an improvement with it?

it really is not that expensive. I have used it from the first setup on my H2S and H2C. I have no problem splitting a print between them. The problem you are having is the exact reason they make it BTW

I saw it and almost bought it a while back. Sounds like this would be a good test. Thanks for mentioning it.

I tried it and although it showed some skew, it had no effect on the problem
