Attaching spring steel more firmly?
Is there a good way to tie the spring steel plate down more firmly than the magnet can achieve?
I'm thinking small powerful clips in each corner to prevent the steel from lifting up.
Unfortunately the magnets alone are not doing the job for large, tall and thin diagonal prints :
Re: Attaching spring steel more firmly?
you could always try binder clips

Hi MrMik,
you could try Swiss Clips
I took the little pin off, at point A, so that the clips slide between the x frame and the heatbed!
imagine the fibreboard in the picture is your heatbed, and the glass is your steel sheet

Thanks Chris and Joan!
Those Swiss Clips look great, if they are mechanically strong. Low profile will help, maybe they could stay on semi-permanently without breaking the PINDA.
I used the clips in the photo today, the print is progressing so i'm not certain if they are strong enough, but probably. 3 in one corner, 2 in the other.
But, they have a high profile and I had to wait 30min before I could install them during the print.

I am using Swiss clips to hold a steel sheet to my mk2 printbed, admittedly I am only making thin prints, but the surface finish matters...
it's so much easier to remove parts by flexing, rather than digging with a spatula

Do you have to remove them before starting a print?
Re: Attaching spring steel more firmly?
What about stronger magnets, and more of them. Maybe with N50 or above?
By the way, two of my magnets have fallen off. Are you sure you have all of yours where they belong?

Hi Mr Mik, I have never needed to remove them yet

however I suppose that depends upon how close you get to the edge!
as you can see, there is very little intrusion, and if it were a problem, I could move the clip to the front of the bed, rather than the side!
the rear clips are on the back of the heatbed, because there is not quite enough room between the heatbed and the ribs on the mk2 power supply, if I were to use the clips on my mk3, there is enough room for them to go on the side.

Re: Attaching spring steel more firmly?
There's another thread on magnet re-attachment, but I'd definitely check your bed.
Mine came with one of the corner ones off (and attached to an adjacent one.
I used high temp epoxy readily available in the US to re-glue it (being careful to get the orientation right, though that may not matter).
I used wax paper and a binder clip to hold the magnet in place while the epoxy cured.
For me, the magnets are so strong, I can't imagine a corner of the sheet being loose.
