Why is my print skewed?

You should reduce the acceleration for the Y axis to solve the problem rather than changing the speed. Of course you could do both but skipping steps have more to do with the motor being incapable of accelerating the load fast enough rather than the top speed it can reach.

Thanks, I'll try that. I printed another cube with the lower speed and this one came out very well.

There are a lot of parameters and each one has a function and some have side effects.
