During a recent print, I paused because I could see there was a plastic problem, so I homed in X and Y.... of course, the nozzle sitting there oozed etc, so I primed the extruder....

when I resumed, the extruder RETRACTED the amount of extrusion I had extruded to prime. In other words, when I manually extruded 150mm of extrudate during pause, I subsequently incremented the E position.

After resume, the next E command is now 150mm back, so it retracts 150mm.

On Pause it would be nice if Pronterface took note of the next XYZE position (in the last command, and moved to Z, then X/Y, then G92'd the E to the last command's value.

I say Z first, because obviously you don't want the print head going THROUGH anything that's on the table, and well.. the E is obvious I think.

What do you think??
