Today the Huxley printed its first parts. The hot end jamming problems were traced to obsolete firmware that incorrectly read the temperature. Due to the low extruder temperature resulting in only partially melted plastic and corresponding high resistance when printing.
With the updated thermistor settings the extrudate flowed freely.
The first print did warp – this may have been due to an incorrect temperature setting in the bed.
With a bit more care subsequent prints were of higher quality.
Two more PCB clips were printed and fitted to the Huxley.
