Yes, sorry for the hijack. It was just an out-of-the-blue idea which popped in my head in reaction to Schooner's post. And yes, I meant that commit. I remember from my LinuxCNC days that CPU hogging, as you aptly named, used be the thing. (Not so sure now as I don't follow that project closely,

Schooner, Sorry for not saying but yes, I was/am installing for Beaglebone Black on Stretch. I was able to purge and re-install. The fixes are there and machinekit now appears to run properly (in house). Now I have to take it back out to the shop and test on the X2 CNC minimill. Now I also nee

BTW, did someone else (than Zultron) try to use the core isolation feature to "turn on" back the step signal generation in software? My electrotrash which I use for Machinekitdoes not have cores to spare. And Elephant period is nice name. The servo period was always problematic name - maily bec

Well, I meant why did you remove it from the template you say you are using? I was going by that you are trying to load it somehow else and are getting bitten by synchronization. (As Luminize said, these is no CNC without motion component.) And yes, the documentation is not okay. I have been me

OK I have found the problem, an unintended corruption of the package name, causing an overwrite in the Packages text and linking to the wrong package. I have pushed a fix, but it needs to be tested, merged and in the meanwhile I may need to purge the repo or
