Still the same problem.

Why reading the temps so often???????????

This is causing the problem. The printer controls the temperatures itself so why reading it every 0.5-1.0 seconds?

And why reading nozzle temp and bed tem at the same time? Its a simple change to alternate this.

And the single threaded moe model..... makes things so slow on a Mac.

Its a pity and there are many Mac users but MC needs some tuning.
