Nozzle Dragging on Print Bed Before Print

Posted · Nozzle Dragging on Print Bed Before Print

Hi,

I recently received a 3D printer for Christmas and have been playing with it non stop because it is so cool. Anyway, I initially had a few problems starting out, but I was able to solve them all until my printer started to drag across the print bed before a print. What I mean by this is that the print starts and then the printer decreases Z-height even though it is at the minimum Z-height it can be at. This results in the nuts that push the X carriage up come out and the nozzle is rested on the bed and it causes prints to fail as no filament can come out. I am using Cura as my slicing software and the software was working prior to this but all of a sudden something happened where the printer thought that it had to decrease Z before a print, even though it doesn't. My bed is level and my nozzle is at the correct height and everything else mechanical is working properly. If anyone has any idea how to fix this, please let me know as it would be greatly appreciated for I want to get back to 3d printing as soon as possible. Thanks!

        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
