Hi Community!

My huge print (already 20h) with a very filigree top side ended up in trash.
I´ve added support structure and sadly the Z-hop crashed my print.

After testing a while, the V4 works correct, means every time the nozzle travel with Z-hop.
In V5 the Z-hop between isles (support with model on top and the model itself) is different.
Sadly it not conequent lifts off.

If I make a factory file out of V4 an open this in V5 it works like before.
With a new process created in V5 an switch to absolutly the same Values like the V4 one, dont work

Could you PLEASE repair this!!
It is very annoying to jump between the versions..

Thank you in Advance!

Could you attach the factory file from both V4 and V5 here? I would be happy to look at it.

Of course
First two pictures to show you what I mean´t.
Import: Native:

Hi,

I don't have v5 at hand but looking at the process definitions I might have an idea what's causing this:

On the advanced tab there's a setting called "minimum travel for retraction". This is set to 3mm inside
the import-factory-file and to 10mm inside the native one.

The gap you've shown in the screenshots is likely < 10mm and S3D won't do a retract - therefore
omitting the z hop you're hoping for.

Edit: You might also want to check out your retract starting positions. The min travel distance is about
the length of the travel move, not the distance of the islands themselves.

Cheers,
Daniel

p.s.: Sorry, keine Ahnung wie die Option genau im deutschen GUI heißt - könnte ich nur für v4 checken.

Even if the connection between Retrakt and Z-Hop is not entirely clear to me,
I'm a bit embarrassed now.
I had checked the settings X times, but probably forgot to save them once.
That's it, thank you very much, also to community!

Danke Daniel!
Viele Grüße
Josef

Z-hops are tied to retracts. The minTravelDistance defines _IF_ a retract will happen. So if
the travel distance is above the limit you will get a retract + travel move, otherwise a travel
move only. No retract, no z-hop.

The minTravelDistance is the length of the travel move - this can be irritating when looking
at the islands first, because how far the head will travel depends on where the start/end
location is set. Even more irritiated now? ^^

Sometimes a picture can be worth a thousand words, here we go:

4 simple boxes, 1 perimeter only. z-hop @1mm for visibility, min travel for retraction set to 10mm: Layer -> start points are set to 0, 0 - the lower left corner of the bed. Although the boxes aren't
spaced > 10mm it will always do a retract + z-hop because the travel move is > 10mm.



Same settings - but this time the layer->start points are set to the center of the bed, not to the
lower left: Notice how no retract/z-hop happens between the center boxes because the distance travelled
here is now < 10mm.

I'm a bit embarrassed now.

Naah... that one can be tricky. The other retracts "hiding" this (if enabled in the preview) just
adds to the confusion.

Cheers,
Daniel

Thank you so much, Daniel!
