The DaVinci 1.0 I have appears to have a brass head and I'm curious about whether it really makes a difference to do bed calibration / leveling with the bed and extruder at printing temps like I thought.

So something that is 1mm at room temperature is 1.0012mm at 100C.

A feeler gauge won't be that precise to begin with.

I tried to google a bit on the expansion properties of items, but quickly got buried into very detailed topics rather than some high level guidance like I needed. smile

Does anyone have thoughts on whether a metal feeler gauge would expand when trying to manually level a hot bed and extruder?

Would the feeler gauge expand enough to make a difference when its in contact with the bed or extruder? Any references?


I have use this method reliably for many years. Even if it did expand the difference is almost non-existent. I mean at the precision level of our machines or any 3d printer for that reason it would make no difference. Remember we deal with two decimal places. while the expansion of that feeler gauge would be at four maybe even 5 decimals.
