Restart or Prime amount issue


Recommended Posts

Posted (edited) · Restart or Prime amount issue

I am trying to overcome what I call a Restart issue.

This is where the Walls start after a travel move.

I have tried values in 'Retraction Extra Prime Amount' from 0 to 6 in various increments to no avail at all ūüėě

Values in the screenshot here.

 

Thanks for your advice.

    Coasting is the probable culprit with Combing a close second.  If you are using them both it's a tie.

    Coasting allows the pressure in the nozzle to fall off as the head decelerates.  It makes for a nice finish on skins, but causes under extrusion when it gets to the next move.  If there wasn't a retraction between the end of a coast, and the start of the next move, then there is no prime and so your "Extra Prime" didn't work.  You'll notice that Coasting is in the "Experimental" section.

    Combing is usually preceded by a retraction but long combing moves can allow enough drool that the prime isn't quite enough to get started on the next extrusion.  Extra Prime can help in that case, but it does the Extra on every prime, not just those that are after long combing moves.
