<p>I am using &quot;Pretty PETG&quot; along with PrusaSlicer's consecutive print mode.</p>
<p>What I am noticing is that upon finishing the first print, the printer hits <code>MINTEMP BED Fixed</code>. I'm not sure if it's immediate because I let the prints run overnight but I assume the bed cools down and then the error is hit.</p>
<p>I'm just starting to learn G-code and my initial thought was there's an errant bed temperature instruction but the only <code>M140 S0</code> instructions I see are in the <code>end_gcode</code> and near the bottom of the file. Maybe there a <code>goto</code> in G-code which may be running after <code>M140 S0</code> which then causes the <code>MINTEMP BED</code> issue? Perhaps there's something else going on?</p>

0.2 mm and 0.4 mm are half the diameter, but the maximum flow is not just half: Flow scales with the area. The 0.4 mm nozzle has an area 4 times as the 0.2 mm one:
$\frac{A_1} {A_2}=\frac {0.2^2}{0.1^2}=4$
You need to reduce
```
print speed
```
or the
```
volumetric flow
```
by this factor or make sure your printer can handle the increased flow by reducing the viscosity of the melt - for example by increasing the print temperature.
Also note, that a 0.2 mm nozzle can't be operated with layer heights above 0.15 mm.
