Support hard to remove

[haimiko]

Having issues finding the sweet spot for easily removable supports. I've got the ideal horizontal separation but when I try changing the upper/lower vertical separations to anything greater than 1 then the layer above the support is too high and does not turn out right. Any ideas how to fix this?

Lower your print temp a little. What kind of filament are you printing? Some plastics like petg are inherently sticky and supports can be hard to remove

jimc, logical suggestion. Just what I was thinking. I have two different printers. With one, I'm not experiencing any issues with support removal. It's the other one that is baffling me. I'm Printing at 235C with ABS and yes I know that's high but I tried reducing the temp by 10C and I get layer separation when the print is stressed.

Yeah its a balancing act. You have to find that middle ground that works. Other than temp. 1 layer horizontal gap and a vert sep distance of .5mm there is not much more your going to do. Obviously the higer the suport density the more its going to stick as well

The number of layers for vertical separation should probably be a measurement, if you ask me. Try sticking to the .3 - .5mm rule jimc mentioned. So, if you're printing with a layer height of .3 then leave it at 1 layer for the vertical separation. If printing at .25, then try 2 layers for the vertical separation.

Don't be afraid of using dense layers. Try 3 at 70%. Again, you'll need to ensure there's a .3 to .5 separation in vertical and horizontal spacing.

Thank you. Will give it a try.
