3.1 Before your fist print, you need to calibrate the printer. The nozzle should be -+ 0,1mm from the bed when it’s at the “Z-home” position. It’s more or less the thickness of a sheet of paper, so you can make sure it’s at the right position if the paper sheet can slide between the nozzle and the bed, but when 2 sheets can’t.
3.2 Your first difficulties will be usually to make the PLA or ABS stick to the bed. The best trick is to spay hair spray before the print. Also, the nozzle should be really close from the bed.
3.3 It’s easier to start with PLA first. The learning curve is quite steep with 3D printing. ABS is more difficult to print and if you start with it, the situation might get frustrating… Built your skill with PLA printing, then I suggest to try ABS.
3.4 If you print mostly ABS, the bed temperature should be around 100-105C It’s faster to heat it if you add fiberglass insulation under the bed. Make sure you put a material that is fire resistant.
3.5 Suggested temperature:
PLA : Heated bed 60C and Extruder 190-200C Fan : 100%
ABS : Heated bed 100-105C and Extruder 210-220C Fan : 25-45%
3.6 Lubricant: you can use a “PTFE” lubricant such as this one: http://www.homedepot.ca/product/4-oz-bottle-oil-with-syncolon-ptfe-lubricant/849392
