tonight i had cut a dozen parts out and all a sudden the jogging stopped working. more like the keyboard was disabled, but there motors are holding torque. now my computer is saying that the parallel port driver is missing and wont reinstall. so going to store today to finally get a new pci card. and just a side note just after this had happened mach crashed and burned for the first time, all the dro Numbers turned to letters??? weird! so perhaps all my problems have been with the pci card? will update later.
