Printer skipping right through the filament priming
Posted
· Printer skipping right through the filament priming
Could it be your pulleys are loose and you need to tighten the set screws? If so you would see the motor turning in X and Y but the head not always moving.
Anyway to debug this I would send gcodes manually one at a time. I would start by learning what they all mean and then install pronterface. Connect to your printer through a USB cable:
Once the connection is working well home the head and then move it with G commands and move the extruder. Experiment. Do the same commands that are in your gcode files. It could be that you aren't setting the extruder back to 0:
G92 E0
The extruder will ignore very long moves (not sure what is very long? More than 3 meters maybe?) so if you finished one print and then start the next one and the first extrusion is the prime it might be like "extruder is at 5 meters and now you want me to go back to 3mm position? Sorry: no.".
