I usually see some kind of metal backing on Voron 3D printer gantry and I wonder why. People claim it helps to prevent bimetallic thermal expansion effect on their 3D printer axis due to different materials, aluminum extrusion and steel linear rail. In this video, I am doing little experiment to see if one really needs to purchase the titanium backing plate to curve the bimetallic thermal expansion effect. Do we really need it? There is no deny about bimetallic thermal expansion but how much does it affect when most Voron chamber temperature is about 50°C to 60°C at most.
I almost melted my linear block plastic if I didn't turn off the heater.
