Unresolved Extrusion problem

During prints the robo 3d will not extrude any filament, but if I just preheat it and turn the gear manually it extrudes just fine. Any idea why this might be happening?

 

Have you have double checked all electrical connections? I had to reseat a 2 of my connections out of the box when I did a walk through inspection. I also had to re route a stepper motor wire the factory had rubbing against a lead screw.

Great printer thus far, but I have noticed some sloppiness in the assembly and issues in their documentation too.

Hope this helps!

I have checked all connections already. The gears are spinning while it is "printing", it just isn't extruding. If I spin the gears manually it works, but when I start a print the gears spin and nothing extrudes

 

Sounds like an issue with the z offset. In your case you want a larger negative number to get more space between the nozzle and the build plate so it can extrude properly. Make sure to write down your old z offset in case it doesn't work and you'll have a number to revert to.

 

I have had that happen a few times. It seems like a communication glitch when your printing over usb and the bandwidth is being bogged down by the computer. I have even had some bad models to that

mine does this as well! Tech support wasn't very helpful either -_-

 

Check to see if your extruder temperature is set properly in the filament settings of your slicer too low of a temperature will cause the filament not to extrude, but the extrude gearr will still turn during the print.

Hope this helps let me know if it doesn't.
