Reusable Spools

Hi.
I got an AMS unit. Is now my second. The required hub is still a long time coming but ok. But one thing makes me think. It is advertised that there are four spools. 1x PC/ABS Alloy Material High Temperature Reusable Spool, 3x ABS Material Reusable Spool. These are empty spools. What exactly do I need a high temperature reusable spool for? Is it necessary to use a high temperature spool in the AMS? Sorry i does not understand this. What is the difference in the AMS unit ? Sorry for this stupid question.
Sorry for my bad english.

the high temp spool is if you want to remove moisture from high temperature filaments like ABS and CF
if you use a ABS spool to dry abs then the spools could melt
so using a ABS spool for PLA works fine , but not for the same material
so a high temperature spool wont melt in that case

Thank you. That makes sense. :wink:
