Replicator 2x is destructing its build as it prints

[Sebastian Finke]

well, the second issue has definitely been fixed, but the filament keeps clogging itself.
will try to recalibrate it, but makerware for linux doesnt allow me to set different speed for different steps.
Thanks for the tips anyway

I don't use Linux myself but you should be able to create your own profile (as opposed to using the default ones) and this will open up a ton of options. Us Windows users use Proftweak to edit these but you can do it in WordPad or the Linux equivalent too. Proftweak is definitely easier to use as it gives a nice overview; with WordPad you'll need to go through it carefully but it is possible. Bottom line: don't use the default profiles.
