I have used the typical LM317 circuithttp://www.ee.buffalo.edu/courses/elab/LM117.pdf with a salvaged, 30v printer power supply. It adjusts voltage but there is absolutely no measureable current. Can't turn a small motor that runs easily on a 9v battery at 53 mV. If I replace this circuit with the current limiting configuration, won't the amp burn components?

Sorry, I am not experienced. The 53 was the load taken while running it off the battery.
I set the multimeter to measure the resistance (through the multimeter) while under load.

I should have avoided details about the motor because they digress from the immediate problem: Why is the circuit regulating voltage but killing the current? I'm using a 240 ohm resistor and 5k pot.
I set the multimeter to measure the resistance (through the multimeter) while under load. In any case, my circuit is adjusting voltage, but killing current. After reviewing the tutorials, there seems to be no mention of how to fix the current while regulating the voltage.
