Support blockers not working?

Hi guys, so this may just be me but try to add support blockers and enforcers on to a print and studios just ignores them and puts the support tree where it wants? And what’s even worse is that it decides to put the tree outside of print area?? After some playing around with the tree styles, I’ve managed to get a support to work, but going back to my main question, the support blocker is NOT blocking the supports in a certain area?? Is there something I’m missing or doing wrong?



In your first photo it looks like the support blocker in positioned below where the support would meet the part requiring support.

I think you are assuming you block where the support would start from.

If that is true, you need to switch how you think about support blockers.

See where the support would make contact with your model, position the support blocker so it covers that area.

The idea is you say “don’t support this section of my model”.

Thanks for the reply back. I guess I am looking at it from the wrong perspective. I guess my question should be then can you prevent the starting point of a support? I thought the a blocker would prevent any support in the area highlighted, start or finishing. And an enforcer area would state a more desirable starting point?

You can restrict the support to build plate only, to keep supports from being built on other surfaces of the model. There is no other control over starting points.

Edit: you might want to design your own supports as part of the model.

No, there is no control over starting or finishing in that respect.

You focus on where the support is needed and then control if you insist it appears or prevent it from being automatically generated.

Depending on your needs, this is the best strategy.

You can design a model (think part) as a separate STL and then in BS use the “Load…” menu option from any of the Part menu items including the support ones.

This will turn your support-only part in an STL into a specific set of supports for your model. This would likely give you the control you need.
