To further optimize print quality even at very high speeds (I aim for roughly 80-100mm/s), I enabled S_CURVE_ACCELERATION and tweaked the jerk and default acceleration values.
Note: This is still in testing. As soon as I finish and it works as I like, I'll push it onto the master branch. If you see this commit on the master branch, it's safe to flash.
Using TMC2208 in standalone mode, I've inverted the stepper direction to match Anycubics pin layout. M110 memory watcher was removed due to redundancy and - ironically - to save memory.
