Is there any chance on showing the current Extruding speeds? maybe on the MCP next to the Current Pos? this would be an excellant addition to your software.
Most CNC Controllers have this feature, it's helpful to know how fast the printing speeds are in real time. Just in case your "processes" wernt set correctly, you then could use the "override" settings to get to the right speed.
Right now you can't tell how fast the printing really is.....
