Hello, i have an old PC with parallelport built in the Mainboard. The adress PC Style is 0x378 shown with dmesg. Now my Problem is, i have no connection to my stepper motors. I think the Problem is the connection from the PC to the breakoutboard. I have two types of breakoutboards which i can use. A China db25-1205 Board. And a mach3 v2.1 board. Can somebody help me.
