I’ve recently change out the bushings on the print head, but something is out of calibration, or out of whack. My prints aren’t printing correctly, they are out of shape.
After changing out the bushings I printed a part, but found that the round shapes were oblong. So I printed a 20mm calibration cube, found the calibration was off, made the calculation changes, input them into the firmware, then printed out a new 20mm cube, and it was right on the money.
I went back to making my parts to find out that the round shapes were still oblong. So I created a 20mm round x 20mm high part. Here is a pic of the 20mm round print. But it’s not round, it’s oblong or egg shaped. The shape dim range from 19.60mm to 20.75mm, and the height is right on the money.
Help, what did I screw up? How do I fix it?
