I have a Z370 and Z390 .... but ubuntu not debinan .... I have not problem with acustic alarm .... ut latecy is about 40.000 ... no good for stepper ... but enought for ethercat. bkt Il giorno dom 15 dic 2019 alle ore 01:20 Gene Heskett <ghesk...@shentel.net> ha scritto: > On Saturday 14 December 2019 15:38:17 Alec Ari via Emc-developers wrote: > > > Hi everyone, > > Are people more willing to risk possibly higher latency with RTAI to > > use Intel integrated graphics to save them the trouble of using FBDEV > > or VESA drivers?
