Help me select a Z probe with high measuring distance
-
Hi I need to select a z probe for the printer in our company. We are building a 1x1x1m printer using pellet extruder instead of classical fillament extruder. I want to create a mesh of the bed but I am unsure what z probe would be suitable for this application.
I dont think that mechanical probes like BLTouch would have sufficient reach of the probe - required reach would be aroud 2-3 centimeters. Material of the printing surface is yet unknown.
What z probes would be good for this application and compatible with Duet hardware (MB6HC)? -
@qlqlo you still would need to zero the nozzle to your print surface so any existing probe could work?
Also, larger distance sensors tend to have lower resolution, so they may not be applicable for measuring the print bed.

@qlqlo See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_choosing
Inductive probes (NPN version rather than PNP, as it is easier to wire to Duet, see HERE) seem to have the largest range, for example here's some with 30mm range and available up to 50mm range, though they get quite chunky at this size. Not sure on accuracy either, without looking at lots of spec sheets!
