Have any Slic3r users encountered lines of G-code containing a feedrate of zero?
I ran into it this week. For a while I thought something was wrong with my printer firmware or electronics, or something. I’d started the print and it ran fine for the first few layers, then it stopped dead. Only way to recover it was to reset the arduino. Then I started some test runs with no extrusion and realized it was stopping at the same point in the print every time. This pointed to a G-code problem. I groveled through the G-code a bit and finally found it. A line that looked like this:
G1 X1.234 Y5.678 F0.000
The machine would run fine until it hit this line. Then it would dutifully sit there, moving at a feedrate of zero, until it reached the appointed coordinates, i.e. forever.
