I am using a Prusa i3 with Marlin Firmware.
All the components of my 3D printer working fine. I have a problem with my Z-axis, it comes down and get pressed by the bed. I have tried adjusting the endstop switch and calibrated the Z-axis still Z-axis comes down while printing.
edit: - additional information -
While printing the first layer is printing okay, but while filling the inner layer and continue with the next layers the nozzle actually drags and pressed the print.
Can anyone explain why this happens?
