Z Hop on Skin

Recommended Posts

Hey,

Couldn't figure out to to create a pull request so just posting here.

Is it possible to add Z-Hop on Skin to try and eliminate scratching on the top surface?

Or is that already on the list of things to do?

Hi, I'm also interested about this aspect because I don't succeed in managing the z-hop.

I would want to know if there are parameters that inhibit the use of the z-hop such layer height, retraction, speeds, fix horrible...

Most important for me is top surface, too. But I'd like to use z-hop on other layers...

My retraction config is:

Minimum travel: 0.1

Enable combing: all

Minimal extrusion before retracting: 0.0

Z-hop when retracting: 0.05

No changes work... :(

I'm sure that error is mine, but I don't know where is it!

Any suggestion will be appreciated!

(using Cura 15.02.1)

Ok...With 0.5mm z-hop works!

Thanks a lot!!!!!

But there is a diagonal scratch that I thought z-hop would solve and didn't expect me:

It's not extruded material. It's a hotend crawling, because the buildplate doesn't go down.

How can I avoid it?

ok!

I tested this suggestion:

http://umforum.ultimaker.com/index.php?/topic/4581-scratch-on-the-upside-surface/

- I consider point three not good for me, cause the extrusion was concentric (agreeing with "IRobertl"). Maybe, it could be useful for others..

- Very very helpuf point one (combing off)! ....for the top :\ For previous layers, instead, have great quality, but printing time increase too much because z-hop happens every single row.

So, now I'm searching an intermediate solution: same quality, without so many z_hop then quicker.

Any suggestion? It's becoming urgent for me to find a solution... :(

(I'll start trying "no skin" in combing option)
