Inductive bed leveling sensor

CarlBosson

I was hoping for so more advice on this topic. I originally asked about using an inductive bed leveling sensor with a Buildtack magnetic build plate. I would also like to be able to continue to use glass when necessary.

Please see below the inductive sensor I have chosen. I assume this would connect to the "Z Probe" Connector on the duet board? Any advice you could offer would be greatly apricated. Thank you in advance.

@CarlBosson sensing range is somewhat low on that for 3d printing use cases. You should look for 4 to 8 mm sensing range so you have clearance between sensor bottom and nozzle bottom so the sensor has little to no chance interfering with an ongoing print.

Prusas SuperPINDA for example is Pepperl+Fuchs https://www.pepperl-fuchs.com/global/en/classid_143.htm?view=productdetails&prodid=106674 . That has a sensing range of 2mm but makes up for it by being a high frequency sensor.

You will not be able to reliably use an inductive probe with glass. I would suggest a BLTouch or Euclid for that.

@oliof I am sorry I left out some important information. I plan to be printing high temperature filaments in a heated enclosure. The leveling sensor I use will need to be able to handle around 100 deg C in the enclosure. It seems the industrial machines use glass beds? What sensor do they use?
Thanks for you input. Have a great day.

@oliof Wow, sorry again! You were true. I just looked up the Euclid sensor. I think this will work thank you.

@CarlBosson for a 100C enclosure you will need to find a high temperature microswitch, or have spares around for temperature induced degradation. There is a high temp version of Euclid but you need to get in touch with @sinned6915 directly to get one.
