It means you are trying to extrude or move more than the extruder config settings will allow. I ran into similar long ago. Look in your printer.cfg under the extruder section. That is where the max_extrude_cross_section entry is. So you're trying to push 4.357mm^2 through and the config file is limiting to 0.64mm^2. I have mine set to 5 as suggested by the KAMPS purge macro and have had no ill side effects.

max_extrude_cross_section = 5

or 

max_extrude_cross_section = 50

?
