<p>As recently as yesterday, I've had results like yours.  My advice would be to:</p>
<ol>
<li>For extra bed adhesion: Set the heated bed to 75 °C (from 60 °C). Make sure you are using some of the Purple Elmer's glue stick on the bed before printing! I'm assuming you already tried this or have gotten other prints to work very well.</li>
<li>Set the &quot;extrusion multiplier&quot; to 0.95. Your goal should be to extrude 93-95 % of the rate of what you were doing previously. You don't want excess filament that was extruded to &quot;catch&quot; the nozzle and be pulled by it.</li>
<li>Raise the nozzle up about 0.6 mm from where it is currently. If the nozzle is &quot;clearly&quot; too high, lower by 0.1 mm until it's okay. The nozzle could be too low, pushing the filament out wide when it leaves the nozzle, causing stringing. Don't overlook this. I thought I had my nozzle perfect because the layers were sticking. I didn't think a low nozzle could cause that kind of stringing. But it only worked when I took all these steps, including this one. Also, the low nozzle means that when it raises up for the next layer, it's actually still going to contact the filament that was &quot;extruded out wide&quot; from the previous layer. But I think this would be the problem more likely if it was happening around layer 2 or 3, not 5.</li>
<li>Print the first layer extremely slowly, at about 15 % speed of what you're used to / Slicer defaults if you aren't already. Once you reach the third layer, you can increase the speed again. The second layer might be questionable if there's still some stringing.</li>
<li>If those steps don't work, the problem may have something to do with your Z-axis motor driver not getting enough current, meaning your extruder doesn't actually consistently raise up after each layer consistently.</li>
</ol>

K Mmmm
<p>I have a Creality Ender 3 S1 Pro that I'm trying to figure out.</p>
<p>I was able to make 3 solid prints using white Creality-branded PLA without issue and with just an initial auto-level pass, but after that, I had problems with small parts de-adhering halfway through my prints; the first 5 or 6 layers will print fine, and then small bits of the first layer will just slide off the print bed while the extruder is moving.</p>
<p>I think my first layer is maybe not going down well enough, though the pieces that do stick seem to be down pretty well (they require a decent amount of force to get them off of the PEI bed) - the image below is pretty close to the sort of thing I'm seeing with normal prints.</p>

Looking at the squares pattern I'd say your nozzle is too far, not too close. If not, you might be extruding too less.

# Small parts de-adhere halfway through print

(Asked by: username_0 on 2023-07-18)

I have a Creality Ender 3 S1 Pro that I'm trying to figure out.

I was able to make 3 solid prints using white Creality-branded PLA without issue and with just an initial auto-level pass, but after that, I had problems with small parts de-adhering halfway through my prints; the first 5 or 6 layers will print fine, and then small bits of the first layer will just slide off the print bed while the extruder is moving.

I think my first layer is maybe not going down well enough, though the pieces that do stick seem to be down pretty well (they require a decent amount of force to get them off of the PEI bed) - the image below is pretty close to the sort of thing I'm seeing with normal prints.

I've found a brim works for this. Where it might be frustrating to remove a brim, I've suspended the part a little with tree-like supports. I've even had to go for extra wide brims for a part with a small footprint but a little tall.

This part is a little bigger, but also slid off a lot without that nice big brim.
