So, I've applied all the bits from the upgrade kit, including the upgraded extruder feed mechanism, and I'm starting to get a 'paused from error' warning at the end of every print. The print is complete as far as I can tell, and if I simply tell the printer to continue via the play button on the dashboard, it will heat up again, move back, and then almost immediately say the print is complete, and return to the home position at normal speed. This is with FS 0.7.6, machine firmware 1.6.51, and I believe the toolhead firmware is 1.2.7 (Upgrading to 1.2.13 since I had it already downloaded made no difference)
However, after doing another print and getting the same warning/error, it appears that the issue may be something to do with filament detection being a bit screwy? It paused with error at the end of a print after I upgraded to the 1.2.13 firmware because I downloaded it before it was pulled off the site, and this time when I went to the dashboard it said out of filament, so I simply started it again, and it warmed up and completed. Next up, disable the filament detection to see if that is really the cause! Very strange that it only happens at the very end of the print... something to do with the end gcode retaction???
