Horizontal move = dragging / scaring

[gajtguy]

So what is the trick to getting the unit to always z-hop when making a horizontal relocation move? This happens due to the slicer I use (Cura v15) designing weird paths when filling in a horizontal surface. It winds up leaving scars, or dragging across an otherwise good horizontal surface. Are there settings to prevent this, or a slicer that handles this better then others? What is this marking actually called (is there an official term?)?

It looks "puffy" like you're over-extruding. Have you calibrated that setting yet?
As a quick fix, you could turn down your extrusion multiplier. Looking at that piece, I'd try it around 85% and see what happens.

So I'm back on to this issue. I've been printing a bunch of stuff lately. To your reply, do you typically have to play with the 'extrusion multiplier'? Right now I've got the filament diameter dialed in for what I measured and in Cura there is a "Flow %". So having to dial that back to 85-ish is something I never considered playing with. But I guess it's a user field for a reason. Worst case is the Rostock has the flow percentage that can be adjusted while something is already printing. Right?

Do you think that would fix the 'glide across' marks? I'm curious as to why the printer doesn't z-hop when it has to cross over already printed area of the same layer. It z-hops when going over "air". This is seeming opposite to me. Can someone explain it to a dummy?

do you have z lift enabled, if so it can be set to a height.
