Raft still sticking (strongly) to part

Postby A6y_N0rma1 » Mon Jun 17, 2019 9:34 pm

I've recently had issues with my raft sticking to my parts when I need to use raft. I have to either cut, sand, or lathe off the raft that sticks to the part. I didn't have this issue a year ago, so don't know if something changed when I upgraded to ideaMaker (3.4.1) or I accidentally changed something in the slicing parameters. I've tried increased the raft to model gap to 0.35 mm, but still no luck. Should I keep trying larger values or is there something else that I'm missing?

BTW, I'm using Raise3D Premium ABS filament and printing at 230/110, Bondtec extruder with Olsson Ruby nozzle and GeckoTek flexible plate.

Found some advanced settings for raft in ideaMaker. Noticed that the surface layer (assumed this would be what the model would build on) has a default Surface Layer Infill Ratio of 85%. I lowered this to 33% thinking that less raft would not adhere as strongly. The raft peeled off rather easily. Will have to pay around with this setting to optimize it a bit, but this setting seemed to fix the problem for me.

There is also a settings in ideaMaker, called Raft Gap. You can also adjust it to increase the gap between Raft and first layer of Model.
