I have just got a Monoprice Maker Select 3d printer (which is really just a Wanhao Duplicator i3).
I want to print a model that came on the included SD card (
1.gcode) with ABS filament. I first press "
Preheat ABS" and wait for the display to show the correct temperatures, 245°C for the extruder and 90°C for the print bed. Then, I mount the SD card and select the file to print.
However, once I do that, the "goal" temperatures change to 195°C for the extruder and 50°C for the print bed, and the temperatures reported by the printer gradually go down as the printer waits for it to match the "goal" temperature. This results in a failed print, with the filament sticking to the extruder in a clump.
What is going on here? I am trying PLA with the same file, and it seems to work fine, although the temperature change still occurs.
