Aluminum Bed Thickness for Inductive sensors? So, My Prusa clone has one of those red PCB heated beds, and I have a piece of glass over it. I want to use an Inductive sensor. I was going to order an all aluminum bed. I can get a great price on a 2mm thick one. But would a 3mm work better?

Then I will stick with my glass and i have a Strain sensor for my nozzle on order. My Inductive sensor is rated at 2mm. So not much room for error.]]> disneytoy General Fri, 08 Dec 2017 03:23:31 -0500 https://reprap.org/forum/read.php?1,799903,799915#msg-799915 Re: Aluminum Bed Thickness for Inductive sensors? https://reprap.org/forum/read.php?1,799903,799915#msg-799915 On my 3mm MK3 heatbed it switches just 1mm above the bed, there is no room for glass. On the other printer I have a 6mm cast aluminum bed and it switches a bit earlier, but still no way to put glass between.
I've heard someone mention, he uses aluminum foil wrapped around the sensor head. He adjusts the height of the foil in a way, that the sensor just doesn't switch. That extends the trigger level above the bed a lot. I haven't tested it yet.]]> o_lampe General Fri, 08 Dec 2017 02:41:31 -0500 https://reprap.org/forum/read.php?1,799903,799914#msg-799914 Re: Aluminum Bed Thickness for Inductive sensors? https://reprap.org/forum/read.php?1,799903,799914#msg-799914 MKSA General Fri, 08 Dec 2017 01:59:14 -0500 https://reprap.org/forum/read.php?1,799903,799903#msg-799903 Aluminum Bed Thickness for Inductive sensors? https://reprap.org/forum/read.php?1,799903,799903#msg-799903
