I would like to connect the different ground wires of temp. sensor, end stop, hotend, and two fans to reduce the number of wires going to the moving hotend sledge.
I noticed that the ground pins on the Smoothie don’t seem to be connected (e.g. ground of hotend and endstop). What’s the reason for this and can I connect the ground pins together?
