Having a Creality Ender 3 Pro. Have upgraded the mainboard to a new Silent mainboard. Installed this Extroduer and also have a glass bed. I also purchased another glass bed to exchange the scratched one.
What should I do about my problem? Is my only solution to buy a CR-Touch Sensor? How does the sensor even work? Will it also scratch it when I am not careful enough or is it user friendly and fully automated?
I don’t have any other bed except the glas one for now. Should I rather purchase a flexible sheet for the bed instead of a glas bed?
Sounds to me like your issue is that the new nozzle now sits lower in relation to the old one. And so now your Z 0 puts the new nozzle tip below where your bed sits.
Since your not using a probe then all you’ll need to do is move your end stop so it triggers at a higher position, and stops your nozzle from ramming the bed.
Move the endstop up higher and then let us know if that helps.
It did help. Always had not give the stopper a thought that its not hard mounted.
