Hi,
make a test:
print first layers
push the button 10 seconds
then go to stop print
say no and look now how fast you can print the first layer :(
second:
endstop check in firmware isnt working
my endstop in a new printer (10 days old) is wrong/defect
no signal to firmware and printer begins to print
printer starts to print.
Since Endstop did not work he does not know where he stands. Can not find the 5 points and pushes the Hotend purely to print bed. Only emergency stop has prevented worse.
