Is it possible to test extrusion e-steps?

Trying to determine if X amount of filament requested actually equals that amount.

I was trying to tune my X1C and follow Welcome! | Ellis’ Print Tuning Guide but I don’t think this is possible since I can’t connect to the X1C via serial/usb.

The tuning procedure you linked isn’t applicable on a Bambu printer. This said, there still is a way to tune/calibrate your filament. It’s built into Bambu Studio.

Thank you. I was aware of the rate flow and flow dynamics, I was hoping to get a bit more granular with the calibration but it appears that is not possible.

Does my post in the link below help by any chance? Not specific to your question on e-steps but other calibration methods if you’re looking to go down that path.

If yes, I suggest you follow this link for manual calibration as the calibration tests in Bambu Studio are aligned with this guide.
