Downgrading from 2.9 to 2.8.4 stretch

Looks like the install went okay. I actually am surprised I built from git without braking it. Latency figures look promising (fingers crossed) servo 7000 base 15000.

I have 7i96 too and I have problems too. Is you problems similar like mine?

Give us feedback, if Debian 11 is solution for us.


This can help you, if you use Gmoccapy:
zz912.webnode.cz/rip-lcnc/
Chapter: RIP LCNC 2.9 Gmoccapy

Will do. So far so good.

I used this to grab the 5.10 kernel:https://theartoftinkering.com/installing-linuxcnc-2-10/

Set isolcpus to 1 for my machine

Used grub customised to set kernel to 5.10
Then used gnipsel docs to install the rest. gnipsel.com/linuxcnc/debian-11-emc.html

Thank you i do need gmocapy, thanks for reminding me of that one. Ill let you know how it goes over the weekend.  Ill run some latency tests then try some pings from workshop when I'm happy ish.

Could be a similar issue to yours from quick glance, not 100% though...

So far servo jitter tops out at 25,000
On stretch the same machine gives solid servo of 5,000 or under. The main thing is does the NIC issue persist. Not sure, yet. Will update my other thread with that info to keep on topic.

I gave up on Debian 11 and installed the Buster 2.8.4 ISO on a new HDD. I am not sure if this solved my problem as both of my configs seems to not function. The router is probably easier to rectify, but I might have to update to 2.9.

For my router, I can not take it out of estop. Any chance someone could have a look to see what I am missing?

I'm not running a physical estop at the moment, but have one to wire in. I just can not understand why it isn't working as before (strange). The sims seems to go out of estop via software okay. Maybe I'm just missing obvious things with tiredness.

The lathe won't start at all (7i96 is throwing a debug error) but that one is running custom firmware from PCW so, I'll address that elsewhere.
