Just as a random comment slightly back on topic, I replaced all settings from the profile and all looked fine. Jogging no problem. However, when I tried to run a g-code, all motors stalled, missed steps and generally died! I couldn't get my head around it. I googled and found a similar issue on cnczone. Apparent!y it can happen when the mobo has in built graphics. Going into diagnostic and turning the path display off cured all issues! I'd like to work around it and have it sorted but at least I'm back up and running.
