    Looks a nice Prusa, wondered what was going on with the extruder until I realised it was a mirror lol.

    You have the mk2 heated bed it takes ages to heat up for ABS but for PLA it's pretty quick. I recommend getting some cork board to insulate under the heated bed, this will really help with heating up times. Another solution is to change to the mk3 aluminium heated bed and power it with 24v but this is more hassle as if you send 24v to the ramps board without modifying the ramps first it will fry the arduino but there are a few ways around this.

    If you use the mk3 and 24v heat up times to 110c are ~ 2minutes, if you use the mk3 at 12v you will see no difference in heat up times at all. The Mk3 also has the advantage that being aluminium you can use a cheap inductive sensor. But I bet you already have autoleveling.

    If you didn't buy it from China the company you bought it from did ;)
