Reply To: Pen came up on its own while drawing

1) I don’t think it’s a sticky vertical slide, but I’ve changed to a somewhat heavier mechanical pencil.

2) I don’t see any loose wires.

3) Maybe a million tiny squiggles, so overheating could be a culprit.

4) Lots of pen lifts. Lots and lots, so not that timeout anyway.

Thanks.
Back to the drawing board….
