Is there a way to accelerate or switch speeds during the lift part of the sequence? For instance: I need to lift 8mm to aid resin reflow. But large surface area requires a slow separation. So I'd like to go slow for the first 2mm of the lift, but then accelerate to a faster speed for the remains 6mm to speed up the whole print. The slow speed is obviously only needed for separation, but the rest of the move being extremely slow is a waste of time. I know we can dynamically adjust speeds per layer, but just don't quite see if there's way to adjust during the lift itself. Thanks.
