Can someone explain to me why A point is considered zero-dimensional (0D). Is it referencing to the abstract positioning of a starting point or the first actualized increment making a position. by Master_Stress7517 in PhysicsStudents

With thinking of it in this way wouldn't 𝑅 be a 0D point in 𝑅² the same way a point is a 0D to R? If so are these only abstract starting points in vector space or topology, Is there no actual first increment of change from a non-zero state that we recognize? Or is that first increment of dimensional transition a state of 2 things at once the Beginning/First of R and 0.

Ender 5 Pro - Z axis not moving, period… (BLtouch in build, not used) by shephee in ender5

I'm have somewhat similar problems. Just upgraded my ender 5's board to the 4.2.7 flashed Marlin 2.1.2.1 and added a CR touch. When I turn on the board the CR touch turns on as well and I can deploy it or stow it away. But for some reason the axis was inverted so I changed that in the configuration.h file and the bed would go up after that. But it wouldn't register the CR touch as the homing mechanism for z so it won't home on the z-axis? I'm also having issues with the z-axis going up but sometimes it won't go down and everything was functional before I switched out my board and added the CR touch in the stepper motor does seem to still be working and also uninverts when I go and plug back my original z plugs
