Extrusion stops working for really long extrusions
Currently failing on a 1974mm extrusion.
- test what point the extrusion fails at
- split contours before planning if extrusion greater than that amount
- also remove contours with less than 1mm of extrusion before planning (up to 20% of contours are less than 1mm of extrusion)
- change Marlin max Extrusion to 5000 and put it on the arduinos
