Print surface for delta with smart effector

[bartolomeus]

I am looking to upgrade the bed of my delta. The delta has a smart effector, and I was wondering if the print surface has any effect on the precision of the smart effector. I think I once read that a pei coated bed + smart effeector is not a good combo, that's why I am asking.

I am looking at getting a cast aluminum plate with either:

• pei coating directly on the plate
• magnetic sheet on the plate
• mirror on the plate (if I use a mirror, I guess I don't specifically need a cast aluminum plate?)

So, what print surface is a good combo with the smart effector?

The Smart Effector works best with hard surfaces. I use PrintBite on my delta, which works well with both PETG and PLA. A PEI coating directly on the plate should also work well for PLA, not sure about PETG as I've never tried printing PETG on PEI.

Ordinary 4mm float glass is good for PLA too too, it's normally very flat (like mirror); but don't use it with PETG unless you coat it.

Thanks! I think I'll go for pei coated plate then and try that first. If I run into any problems I could always put a mirror on top . I have had very good luck with 3dlac+mirror for petg but I don't like using clips to hold the mirror in place.

@bartolomeus i used a magnetic plate with a PEI surface on my delta with a smart effector with no noticeable issues

@jay_s_uk Thanks. Good to know. However, does this also work with a cast aluminum plate with silicone heater (where to attach the magnets?)

what is the thickness of the plate?

[jay_s_uk]

@bartolomeus Yes.
Mine was effectively an aluminium bed with a 24v PCB with a magnet attached on top.

@Veti the supplier I am looking at has 260mm diameter, 8mm thick plates in both pei coated and natural

8mm thick plates i

with that i think you need grooves milled in where you can place the magnets
