![]() ![]() In summary, the OP's Jetway may well be OK for Linuxcnc after all. This setup is using a Mesa 7i76 and a few test cuts all ran OK. Need to spend some time seeing if this can be improved. With absolutely no tweaking, latency-test is showing a Servo thread max jitter around 40,000 ns but once I saw a bit over 100,000 ns. The 2.8 conversion script worked rather well, just needed a few manual edits to get a working dual motor gantry configuration (XYYZ), I very much like the 2.8 joints scheme for dual motor gantry setup, it feels very logical. That worked just fine too, so I copied over a 2.7 config and started up 2.8. ![]() After running with no problems for a day, I downloaded linuxcnc 2.8.0-pre1 from Master and did a RIP build from source. With fingers crossed, booted into it on the otherwise stock Debian 9.7 Stretch and it is working. Then I tried building a 4.19.15 kernel with the 4.19.15-rt12 patches. Tried all the same distributions as the OP, with identical unhappy results. Great news - Linuxcnc 2.8.0-pre1 with a 4.19.15-rt12 #1 SMP PREEMPT RT kernel is working well on a Jetway Fanless Braswell Celeron N3160 Dual LAN.Īfter installing Debian 9 Stretch, I ran into the *exact* same issues as Millerman, the base Debian 9 install works fine, but upon switching to the PREEMPT-RT kernel, after somewhere between a few seconds and a few minutes, it just hangs.

Once built we might be building up to 10 similar machines over the a yr or 2 - thats why i want a currently available computer model - I don't want to try and track down an older outdated unit. ![]() I am using or planning to use (I have it already) 7i96 board Is there a computer that you guys are running that just works great with the preempt_rt kernels ? ![]() Then to top it all off somewhere along the way my bios is no longer available at startup - something to do with the uefi stuff I think - so I need to clear the bios and start over somehow. I have a Jetway HJBC377F531W - Braswell Celeron N3160 - 4gb ram - 128gb M.2 sata hd -ĭual NIC's, lots of USB, Serial ports, I want to like it but it just seems not to want to run the RT kernelĢ - installed stretch from just a debian generic Isoģ - Ubuntu - built the kernel and linuxcnc from sourceĤ - Linux Mint 18.1- updated all the kernelsĥ - Linux Mint LMDE3 - really was liking this solution - was fast - nice looking - easy install with synaptic pacakge manager for mostĪll these flavors work great until I used grub and loaded up the RT kernels - all would freeze with minutes of starting up - sometimes seconds - very frustrating. I need a computer that is known to work out of the box that is currently available. ![]()
