I recently purchased the Da Vinci Jr and I asked my teacher if he had any extra filament I could have, so he gave me about 100m of filament Once the printer arrived I realized I can not use alternate spools. The filament is the same size and as far as I can tell with given specs it is the same. Can I re-spool the old roll with the new material and the machine be fine with it? Will my warranty or anything of that sort be ruined? Also Can I remove 100% of the filament from the machine if something goes wrong?
