Cutting master 2 for corel

[crystaluk]

I have just discovered this and I can cut from Corel! But a few questions.... On the cutting options the speed is max 7cm/s,Force 33 and line types are various. I understand the force part line part but what is the speed and how to guage the settings I am used to?Normally the speed option goes to 10 on the sd so any suggestions.
When I do a design in corel is that automatically cut lines or do I need to select a different option.
Lastly the cut lines seem slightly jagged not clean cut lines is this normal?
(yes I suppose it would help if i did a test cut!)
