This weekend I upgraded from Ubuntu 8.0.4 to Ubuntu 10.04 & EMC2_2.4.4 Release. The install went without a problem. However, I couldn't get the steppers to move. I recall having parallel port configuration issues the first time. I wasted 4 good hours of shop-time with no success. Then the proper information turned-on the light for me, and all is working well. This page on HAL drivers did it for me. I mistakenly thought the "in" and "out" parallel port settings meant the parallel port was installed (in) or not (out). Since I was using an add-in parallel port, I was attempting to set parallel port 2 as the port to drive the steppers. Wrong.
The "in" and "out" refer to the signal directions of the parallel port (I wanted "out"). Here's a hint how to find the address for your parallel port setting (the 'stuff' after the "0x").
