Is there any way to test what kind your filament is? There are no labels on the spools and I don't know whether they are ABS or PLA.

I got the plastic with the printer, which is no longer sold (Solidoodle 2). Since I bought it on eBay that is probably why it has unprofessional filament.

I set my extruder to 210°C and bed to 50°C and it printed fine (with tons of hairspray and painters tape).

I figured out where I got it. I got it from Solidoodle (who have gone out of business) when I bought the Solidoodle 2 right after it came out.

Using The Burn Test to Identify Plastic Materials is one way. From the link:

To initially determine whether a material is thermoplastic (meltable) or thermoset (non-meltable) type, heat a metal or glass stirring rod until it glows red or orange (to about 500°F / 260°C) and press it against the sample. If the sample softens, the material is a thermoplastic; if it does not, it's probably a thermoset.

Next, hold the sample to the edge of a flame until it ignites. If no flame is produced quickly, hold the sample in the flame for about 10 seconds. If the material burns, note the color of the flame, the nature of the smoke, the presence of soot in the air and whether, while burning, the sample drips.

Next, extinguish the flame and cautiously smell the fumes. To identify the odor, samples of known plastic samples for comparison can be most helpful. Finally, check your observations against the known characteristics of each plastic as shown in the table below. Once you have made a tentative identification, it is usually desirable to repeat the flame test once or twice to confirm the results of the original identification. Remember that additives may affect results. For example: flame retardants can mask the polymer material's normal flame & smoke burning characteristics.

However, remember ABS and PLA aren't the only types of filament.
