<p>I'm trying to print lithophanes and having an issue with the nozzle moving through the previous layer and basically &quot;drawing&quot; through the print.</p>
<p>I've printed 3 lithophanes before with zero issues. Here are the settings for those:
0.4 mm nozzle</p>
<ul>
<li>PLA</li>
<li>Temperatures
<ul>
<li>nozzle temperature 210 °C</li>
<li>bed 70 °C</li>
</ul>
</li>
<li>0.12 mm layer height</li>
<li>manual bed leveling</li>
<li>30 mm/s speed</li>
<li>stock Ender 3 mainboard</li>
</ul>
<p>Here's the settings for the prints I'm doing now with the 0.2 mm nozzle:</p>
<ul>
<li>PLA</li>
<li>Temperatures
<ul>
<li>nozzle 210 °C</li>
<li>bed temp 70 ° C</li>

<li>0.12mm layer height</li>
<li>BLTouch auto bed leveling</li>
<li>20 mm/s speed</li>
<li>BigTreeTech mainboard</li>
</ul>
<p>Here's what I've done and looked at to fix it:</p>
<ul>
<li>Calibrated extruder</li>
<li>manual bed leveling, then ABL</li>
<li>calibrated Z offset</li>

lithoophanes are printed standing, not laying.

Wouldn't it tip over from being too thin? Every reference I've seen has it lying flat on bed.  I tried to generate supports in Cura and supports would barely touch it and didn't branch out far enough.

in any case, the lower print does show a lot of overextrusion. like... wrong steps/mm setting.

# Ender 3 nozzle moves through previous layer on lithophane

(Asked by: username_0 on 2020-12-19)

I'm trying to print lithophanes and having an issue with the nozzle moving through the previous layer and basically "drawing" through the print.

I've printed 3 lithophanes before with zero issues. Here are the settings for those:
0.4 mm nozzle

* PLA
* Temperatures
  + nozzle temperature 210 °C
  + bed 70 °C
* 0.12 mm layer height
* manual bed leveling
* 30 mm/s speed
* stock Ender 3 mainboard

Here's the settings for the prints I'm doing now with the 0.2 mm nozzle:

* PLA
* Temperatures
  + nozzle 210 °C
  + bed temp 70 ° C
* 0.12mm layer height
* BLTouch auto bed leveling
* 20 mm/s speed
* BigTreeTech mainboard

Here's what I've done and looked at to fix it:

* Calibrated extruder
* manual bed leveling, then ABL
* calibrated Z offset
* checked for flat spots on rollers, there are none
* tried including a Z hop with little success.
