I am pretty new to 3D printing. I just put together my calibrated my bed and have had some decent quality PLA prints. I want to start trying to print in ABS and was wondering what advice people have for it. I considered putting a closed enclosure around my printer to help maintain a warmer temp inside the printer. Is this worth doing?

Also, I have been using glue on my glass print boards to help stick the first layer to the board. Is this a good idea for ABS printing as well?
