Hi I’m having trouble with supports on prusa when I pain them on the supports are not removable and I seen a comment on lm show of adjusting the distance between supports and part how is this done because I can’t find it anywhere on pursa

@proper urchin @vague wedge
Would like to apologise to the mods of this discord I tried to post this but keep giving errors like please try again latter and eventually after restating the app and trying again I got a note saying I’m being rate limited and realised there’s like 6 posts all the same I deleted all but 1
Heads up I prefer the old version than this one it’s easier to read with out going though sub comments and posts
Any one

Not sure how to do it in PS, will need to take a look. But yes, you need to keep a gap betweem support roof and the part. Around 0.2 - 0.25mm for 0.4mm nozzle usually.
stark cargo
I’m using 0.8mm nozzle
I think I found it I set it to 0.2mm it was originally set to 0mm
Do you like my 1st layer @vague wedge
vague wedge
Looks awesome
stark cargo
It’s solid black but squished to transparent
stark cargo
I would not be able to peel it off I would have to use isopropyl to rub it off
A better photo @vague wedge

I mean, it looks good but oversquishing isnt the best way to go
Elephant foot and all
stark cargo
To be honest I only get a little elephant foot I use a deburring tool then hit it with a lighter or jet flame, torch quickly to remove white marks
I will eventually turn it in till I would not worry about it would not mind to figure out how to get a smooth surface on top just like my clone pursa I3 does a grate job

I prefer to have a little bit of elephants foot and then compensate for it in the slicer
Gives me peace of mind that my prints ain’t going to detach randomly

have you checked off advanced settings
i mean expert
oops wrong one
stark cargo
@vague wedge what size spacing would o need for 0.8mm nozzle
@sleek sand how do you compensate in the slicer
stark cargo
@vague wedge 0.3-0.1 layer height
vague wedge
<@974523779021668432> what size spacing would o need for 0.8mm nozzle
Hmmm, try about 0.35 - 0.45
Use about 70% infill density for the support roof
sleek sand
<@748450392068587580> how do you compensate in the slicer
What slicer
It’s usually called elephants foot compensation or similar
Im guessing prusaslicer
“Elephants foot compensation in X”
X being your slicer

@vague wedge I’m still having issues removing supports it’s stuck to the top layer there’s plenty of space on the sides
vague wedge
You have a pic if the printed part with support still attached?
vague wedge
Which filament?

@vague wedge
I need to increase the spacing between top of support to the bottom of the item
Would you know how to increase the distance between the top of the supports to the bottom of the part @vague wedge
vague wedge
Hmmm, not sure how do set it on PS
I use cura mostly
Will take a look later a bit buzy atm
stark cargo
Sorry
vague wedge
Maybe @proper urchin, @bitter iris or @unique plover can help with ps

I had to use pliers to remove the supports
Pliers will be needed for the most part.
I usually have a flat head screwdriver, plier and a small hammer on hand when removing supports (depending on filament type ofcourse), lol.
stark cargo
I’ve used the same filament on other printers and it’s peels right off
Idk why
It has to be settings

Not sure if it's been discussed. Your z offset distance must be a multiple of your layer height.
For eg if you have a 0.4mm layer height and a 0.1mm z gap, it will probably round down to 0mm gap. So with 0.1mm layer height your z gap can be 0.1mm, 0.2mm, 0.3mm, 0.4mm and so on.
For a 0.15mm layer height it must be 0.15, 0.3, 0.45mm and so on.
So to determine the correct distance we need to know your layer height. I see you are using a 0.8mm nozzle.
My general rule is for the gap to be either the layer height or the layer height x2
Aside from that, if your flow rate is too high, it will squish the filament down more. Additionally if your cooling is not on, or nozzle temp is too high your filament may sag and fuse to the supports in some areas. So knowing these can be helpful.
Some slicers also allow you to adjust the infil of the support density layer. Instead of a 100% solid layer, it can be useful to reduce it to 70% or 50% to reduce the contact between support and model.

Layer height is 0.2mm temp is 200c fans are at 100% and I choose 60% Y/X separation
Here is my latest print with supports removed I filed it back a bit and use a jet lighter to bring back the Color of the filament
@dense violet thank you

Nice work! Using heat to remove stress marks is always a great technique ☺️

Did these supports come off quite easily?
stark cargo
It really I had to use pliers looks like the separation from the side wall of the print to the support material is a bit much and there’s not enough separation between the top layer of support material to the bottom layer of the part
@dense violet
Thank you Matt for helping
dense violet
No worries 🙂 I'm not sure if Prusa supports it but I'd look at bottom layer flow rate and bottom layer infil pattern to reduce the bottom layer from fusing as much. Or even use a thinner extrusion width for supports so the support is less stiff, more pliable.
