Curling Filament Before Running a Print Job

I do the same thing and I use that as a way to keep the nozzle semi clear of old filament it will most likely never be an issues especially if you use skirts (highly recommended) as these are printed first and outside of your print the extra filament will be taken care of before your actual print starts.

If I may, the 220 you mentioned seems a bit high are you using PLA. If you are new you should probably start out with PLA it is much easier to get things going as you become accustomed to the aspects of 3d printing once familiar then I would move to ABS If you are using PLA then I would recommend temps starting at about 200 first 195 others or even a bit lower 195-190.

 

ABS tends to cool off very quickly so extreme differences can easily occur when using ABS and if this happens your print can lift off the bed even if every other aspect of teh print goes well it can lift right off and it can also warp getting a long flat level print is tricky again because of the temp issues it can twist and warp. That is why you hear using a heated chamber works well for ABS because the temp is much more controlled.

PLA has little if any of this

 

It should be pretty quick you may want to drop them a line as well though just to make sure they got it
