Do you guys think that a 2mm aluminium sheet under 3mm borosilicate glass would work for an inductive sensor?
If not then what thickness/material would I need? I can also get 6mm aluminium but it would take forever to heat up then.
Thanks!
Depends on the probe. Different models of probe have different sensing range.
It’s a LJ8A3-8-Z/BX. With a 8mm detecting distance.
I tested a 4mm sensor on 3mm aluminum, worked fine, and even sensed through a thin sheet of glass but was right on top of it.
Given that some people are using even aluminum foil to trigger it, you should be fine.
Ok cool. Thanks!
Wait so foil would work too?
Based on anecdotal evidence, some people have had success with it.
I switched to a MK3 alu heatbed yesterday. I was very suprised to find that my previous setup, where I had aluminium foil under 3mm glass actually gave me longer detection distance.
That is, my inductive probe has to go just as close to the MK3 alu bed, as it would previously do to the glass.
I use a 4mm inductive probe (more reliable than a capacitive probe).
In conclusion; foil works great.
Been using a 30 gauge galvanized steel sheet and works great. Much lighter than a 3mm aluminum plate
