Just started another run with 4 GLX Gears

and this is from last july and have been working OK with 2.7.12

Seems similar but the OS version is different

My guess is this is either OS version related or that you have had some hardware failure coincident with the linuxCNC version change

OK, seems to a bit bad to try to 'go back'.

Is this a good choice for a new PC

I suppose 2G is not enough memory?

Just thinking out load, would removing the 2.7.13 version via dpkg and installing the 2.7.12 version and booting with the 4.9.0-3 kernel be worth a try ?

Would it still be possible to checkout 2.7.12 via git ? And trying a run in place

I'm not totally up on git.
