After a week of playing around with my Lulzbot Mini (excelent machine guys!), I started working on more challenging prints (larger surfaces). This is when I ran into some minor issues: minor warping of abs and visible ridges as a result of cool air drafts whenever I open the cabinet (in which my Lulzbot is placed) to check on the print.
As a test I’ve built a enclosure around the Mini to prevent air drafts and rapid cooling down. I noticed much better prints, so so far so good.
But due to the higher temperatures in the enclosure, I now 
worry about overheating of the Mini (especially it’s motors). What does Lulzbot (Aleph Objects) advice about these kinds of things? Is an enclosure advisable? Or should I take the minor ABS issues for granted to make sure the printer won’t overheat?
