The socks David ordered arrived.  Blue and squishy,

It looks like it is pretty easy to fit it over the head without removing anything to do so – so I did.

Then I noticed that it wasn’t seating well.  On further inspection I discovered there was a lot of melted filament (technically known as “gunge”) stuck to the face of the heating block.  I turned the heat back on, and tried to wipe it off without burning my fingers.  I found that some slightly abrasive lens wipes were the most effective.  They are impregnated with alcohol which might have helped – I hope that’s not a bad thing.

FItted the boot and re-ran the TreeFrog – the one that failed with “Thermal Runaway” last time I ran it.  This time I used absolutely bog-standard parameters supplied by Prusa for Generic PLA.

As usual, the temp sank on layer two.  The temp for layer 2 is supposed to drop from 215 to 210.  In fact it dropped to 205 and then recovered in about a minute.  So far so good.


After each print quite a bit of gunge builds up around the sock hole and interferes with the next print.  Seems important to clean the sock off every 2/3 prints.
