My calibration and settings all appear to be fine on my newly assemble MK3.  For my first run, with every print, it calibrates the 9 points, goes to the beginning of the print only, then moves over to the right side of the printer and requests to Unload the filament.  I unload, reload, then it repeats all over again.

What is going on that I can get a print started?  I have 2 other MK3 that are a year old

is it a mk3 or an Mk3S?

could your filament sensor be giving false indications? 

If you take the top cap and filament sensor off the mk3S extruder, can you see the filament sensor lever moving? 

there is a spacer for mk3S filament sensors on thingiverse

I got it.  The filament sensor cable was turned the wrong way.... Red  goes  to the outside.

We are humming now with our first print.  Thanks!
