[BUG?] Elephant foot compensation not working on MK4

 

I guess the image tells it all. I've tried several options to reduce the elephant foot, but no result.  This is on an mk4.

here;s the file

Best Answer by miroslav.h4:

How do you want to compensate for the elephant's foot when your wall only has one perimeter? The principle of elephant foot compensation consists in moving the first (lowest) outer perimeter towards the center of the print, but here there is nowhere to move the perimeter. If you manage to somehow achieve this (by reducing the extrusion multiplier, for example) the item will fall from your bed. So all you have to do is carefully grind this elephant's foot.

Yes, the picture says it all. First look at the slicer settings (turn off the brim) and only then complain about the elephant foot compensation not working. And send the *.3mf file next time

RE:

I thought it was fairly obvious that the brim was off, this is a 0.2 thick wall with an elephant foot of around 0.4mm a brim is typically ~5-8mm which would flood the entire thing. 

But to be clear: ofcourse the brim was off

 

here's the 3fm file, thnx for the suggestion!

And finally, an addition: print such items in the center of the bed if possible.

You can try experimenting with the width of the extrusion, there is an option to reduce it, but as I wrote, there is a risk that the printout will not stick to the bed.

RE: [BUG?] Elephant foot compensation not working on MK4

Printing a 0.2 mm thick wall using a 0.4 mm nozzle seems a little wild to me, but try experimenting. I don't know what this is for, but due to the thickness it looks like some kind of gap filler between other parts. I would probably make this with thin cardboard or thicker paper, but that's your choice. Unfortunately, this amount of my answers is due to the bad settings of the forum (not enough time to edit an already posted answer).

RE: [FIXED] Elephant foot compensation not working on MK4

Thank you all for you helpfull replies. Good point on the elephant feet. I think i've also fixed part of the issue, cause I was also haveing z-axis issues on the MK4 and given that you cant bed level anymore you're a bit dependent on what the system makes of it. 

Turned out however that my insert (nozzle) was a bit too low installed, resulting in compressed first layers...and the above effect.

What I need it for: I bought some stl files for buildings, which has core construction materials (frames that you slide into eachother) the maker however used waaay too much tolerance so its wobly as hell. Now I can fix the stls but I already had a bunch of frames printed out, for which I needed an adapter...hereabove. 

 

Again thank you for your helpfull insights!
