Hi! After you ran the calibration, did you run the Benchmark Test?
This will give you a better idea of how well your machine is working. There is a spreadsheet that you can use to evaluate the results, and with this information you should get a lot of suggestions from the community…

FWIW, a not so well calibrated machine will generally work better towards the center of the workspace and down lower. The corners, especially down low, are generally the toughest areas to get good results.
