Let me start off by saying I am behind compared to you guys. I have little understanding of these printers and I think I lucked out.
I bought my printer on ebay, assembled it in about 6 hours despite the worst instructions ever and started printing PLA. It has done incredibly well.
I want to print abs, I'd like to print all my spares in abs. So I loaded a file for a test print and abs, the problem is that it has now been over 45 minutes since I started warming the printer up and it still has not reached 100 on the bed. I am thinking maybe I got a underpowered power supply? Or the glass I added is to much to get warmed up?
