Nozzle clearing

When Cura prints a prime blob or performs a nozzle wipe, it always seems to do it *immediately* before moving the print head towards the model. Wouldn't it make more sense to move it away? I've found that things that need the prime tend not to adhere so well, and the printhead routinely drags the prime blob if not into the part, somewhere that it's going to wind up interfering with the part.

 

The same thing with skirt: I've watched it lay down a beautiful line of skirt that adheres perfectly, but then it travels straight to or across the part footprint with a tiny little dangle of ooze that falls off in the least convenient part of the adhesion layer, or it turns out to be the one place in the print that it's going to string.

 

Lastly: is it possible to move the print head outside the bed? I just wonder how many prints would go better if the the head couldn't traverse one of the corners of the bed, with and then lower to { first-layer z - first-layer-width/3 } at the very edge of the bed moving - slowly - to first-layer z as it crosses up to the bed... If anything is hanging off the head, this should knock it off, and the trip along the side and round the corner should help to drag any ooze or string off the plate? (Yeah, it sounds too easy, so I suspect it's not or you'd have done it 🙂

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
