Problems with supports before printing

Hello, Im trying to print a piece, but I need to add more supports on one part and remove support from other side of the print. It’s posible to do that with Luban? I play with the generate support º feature, but when I tried to give more support of one part of the print, others supports appears on other parts, that I dont want to have supports.

Hope my english is good enough
Thank you

Hi, support is added automatically in Luban and can be changed to different types. But it can’t be configured the way as you described.

In this case you need a other Slicer. There are some free like cura, slic3r, and many more.
