When you think about a warped print bed, it means that the bed level is uneven so a nozzle movement from one side to the other will have the print bed in lower and higher locations. Warped Print BedĪ warped print bed is never a good thing for many reasons, one of which being how it can contribute to knocking your prints over, or causing the nozzle to dig into the print bed. Some materials don’t work very well with fans on such as PETG, but we definitely recommend using a good fan for PLA, especially at a fast speed. The fans on your 3D printer can also have a part to play in this, depending on what material you are using. It can take some trial and error to figure these values out, but once you do, poor layer adhesion should stop plaguing your prints to get knocked over. The solution here is to ensure you have the correct speed, temperature, acceleration and jerk settings so you can ensure a smooth printing process. We can see the reason for this being that if each layer isn’t extruded correctly, it can affect the layer above.Īfter a few poor layers, we can start to have material going in the wrong places, to a point where your extruding pathing gets in the way.Ī little bit of contact with the print head and nozzle in this instance is likely to knock over your 3D print, regardless whether you are hours into a print. When you experience poor layer adhesion in your 3D prints, you can definitely struggle from your prints getting knocked over during the process. Let’s go through each of these bullet points and explain how it can contribute to knocking over your prints or even having your nozzle dig into the bed. There are a few reasons that we can get into behind why your extruder randomly knocks over your models.

Read on to find out about specific issues such as printer settings, how to adjust your Z-endstop and so on. This is the basic answer but there is more important information to understand to make sure you avoid this problem in the future. You can also use a Z adjustment in your slicer settings to account for a higher bed surface. This is what tells your 3D printer to stop moving down so much. The best way to fix your nozzle hitting your prints or bed is to slightly raise your Z-endstop on the side of your 3D printer. These aren’t ideal scenarios, I’ve experienced these before but it’s definitely fixable. Even worse when it’s a print lasting several hours. You’ve leveled out your 3D printer correctly and done the normal process of 3D printing, but for some reason your nozzle is hitting or dragging into your prints or scraping and digging into your bed surface.
