Kent, You are correct about the Jetway board, it does not have a build in parallel port. However on the systems I used that board, I was also using the Mesa 5i20 controller with the hostmot2 drivers. So no parallel port was required. The pins to run out a parallel port are provided on the board however.
See Page 7: http://resources.mini-box.com/online/MBD-J-J7F2WE1G5D/MBD-J-J7F2WE1G5D-manua l.pdf A parallel port connector would have to be separately acquired however, as it is not provided with the kit. With the Intel board I am using the Mesa 7i43 which uses the parallel port for communications, not direct stepper control. All of the systems I have done either used servos or micro-steppers and thus required add on boards of some sort. Regards, Eric I see you have just added two excellent latency test results to the Wiki, one for the Jetway J7F2WE1G5D (a VIA C7 CPU) and one for the Intel D945GCLF2 (an Atom CPU), with both showing less than 10000ns jitter in the fast thread. Thanks very much for posting these data but could you please be a bit more explicit... It is my understanding that the Jetway motherboard has no onboard parallel port. What add-on parallel port card did you use in the test you report? Similarly, the Intel motherboard does have an onboard parallel port. Did you use it or did you use an add-on card (and if so, which one) in the test you report? Thanks in advance. ------------------------------------------------------------------------------ Check out the new SourceForge.net Marketplace.
