optimize travel moves

[herzla 3]

I created this little sample model to make testing faster (real model is similar but more complex and bigger and needs 20 minutes to slice)
pls don't recommend to print it upside down 😉

 

i was able to remove all transactions "inside the bowl" by using Combing Mode = all and disabling Z-Hop on retraction but when support is active there is one travel move through/over the model on each layer from support to the shell



to be able to print this part with materials like TPU where stringing never ends I need to get rid of this travels

another problem is that Z-Hop needs to be dissabled so this move goes over the already printed support and oftain touches it - I already needed to abort an PETG print because this travels broke the support
 

 

'avoid printed parts when traveling' is important to be checked
'avoid supports when traveling' does no change

changing 'Z seam alignment' doesn't help also

is there a way to let this travels go around "outside"?
how can I enable Z-Hop again?
model file:  uBowl.3MF

thanks 🙂

Not so Easy .. You can eventually get rid of the movements in the part by using a Custom Support.

 

 

But if you re-enable the Z Hop all the movements in the part will come back.  The only solution would be to use a post-processing script to add Z Hop to these movements. (https://github.com/5axes/Cura-Postprocessing-Scripts/blob/master/ZMoveG0.py)

thanks, you created custom support for this screenshot?
does it look the same when using tree-support?

did you change other option also? I didn't got it looking like yours
