Asrock D1800B-ITX Latency Test 200000

Hi! Can't beat the delay. I tried everything, and Ubuntu 12.04.5 and the subsequent LinuxCNC 2.8.4 Debian 10 Buster RTAI. Can this board even work through the LPT port?

In this  post forum.linuxcnc.org/9-installing-linuxcnc...ages?start=30#149273 , everything is as beautiful as in a fairy tale.. Can anyone suggest Linux Mint 19.2 which   one is used ? And which one  this RTAI?

Hey, that is my fairy tale!
Try this
linuxcnc.org/iso/linuxcnc-2.7.14-wheezy.iso
Linux Mint 19.2 is almost impossible to use as the required dependencies can not be found on the Debian servers.

You were born to make a fairy tale come true! And it works, both out of the box and without the Internet! Thank you very much! There was one caveat, after the first launch I turned on the Latency Test was Base max Jitter:15000 . I crawled through the system, connected the network, opened the browser... and Jitter is a billion ! However, it did not work out to repeat this. There were no more than 15351 during the night.

Glad it worked for you.
Thank you for reporting back.
