Hello, I have to load a new filament and looked at the You Tube Filament and nothing ?
Go jog controls - I click 100 Ext twice and the once. It grapped the filament but nothing coming thru nozzel ?
Help...
Thanks
Loading a New Filament
Re: Loading a New Filament
You have to heat up the nozzle to temperature before you try to extrude anything. There is a lock in the software that prevents you from extruding without the nozzle being hot enough.
Re: Loading a New Filament
Also probably best to avoid running 100mm through the extruder all at once. The distance from where the filament touches the extruder motor gear to the point where it starts coming out of the nozzle is almost exactly 50mm. Some types of filament don't like to be run through the extruder that fast for that long and will have a high likelihood of jamming. Run it through 10mm at a time.
I don't know if that has anything to do with your problem, but it is certainly something to be cautious about.

I'd also suggest making a clean cut of the filament a couple of centimetres from the current end can also resolve problems.
Re: Loading a New Filament
Not sure of the correctness of this, but what I do is heat the extruder by turning it on in the manual controls. Once up to temperature, I back out the filament by running the extruder back 100. Once it comes out, I put in the new filament, and run the extruder forward till the remaining old filament color stops.

Re: Loading a New Filament
I retract at a slightly lower temperature than I feed the new stuff. It reduces the wispy strings that are formed. For PLA I set temp to 190 and retract 100mm, then set to 205 and extrude 100 of the new stuff. If I need it to run clean I may extrude 100mm one or two more times, depends on the object and how much purging is going to happen anyway.
