Retrofit Gloria Europa 2/40 machining centre

That would use standard 7I77+7i76 firmware

Yes, even PCW had confirmed to me that the stock firmware is suitable and we already have the IDC-26 adapter, now we wait for the cards to arrive.

Thanks to everyone.

I finally have the time to continue with the work of retrofit and I would need some information.

I bought a mini-ITX Asus H170I PLUS-D3 motherboard, very nice board, i have disabled all power
management features and audio and left enabled ethernet, integrated wifi and onboard GPU, stock
linuxcnc 2.7 is installed on SSD.

Now with this configuration and isolcpus=1 on linux command line i have very good jitter:
servo thread max jitter: 8230
base thread max jitter: 7892
even if the overall performance is not so good under heavy load.

With same configuration but without isolcpus command line option i have this jitter values:
servo thread max jitter: 24000
base thread max jitter: 28550
and the overall performance is very good

This last values are too hight for software stepper but i use mesa cards for step generation and encoder count,
so are the last values suitable for mesa or i have to go with isolcpus?

Thanks for replies.

As a rough rule for mesa systems at 1 KHz servo thread:

50000 ns latency is OK for the standard position mode stepgen

100000 ns latency is OK if the PID stepgen setup is used in HAL

500000 ns latency is OK if a firmware with DPLL + PID stepgen are used

So I would definitely _NOT_ use isolcpus, it will do nothing but make the system slower

Thank you for fast response PCW, i'll go without isolcpus.

hello see my topick you have the configuration on 6i25 and 7i77 if you want . THe bosch drives work perfect with mesa

Which topic? I can not see any link. However the bosh original drives have been replaced.

Its a good machine for aluminium and steel drilling . Make it a liniar scales you will get a perfect machine on this . if you want the panel with buttons i still have it . If you want the machanical schematics i can give you.

Ah I see, the same as our machine, you did a great job, congratulations, I hope to operate our in the coming days and start doing some work.

Thanks for the info, the machine is in our workshop for many years and has always worked well. We decided to retrofit because the CC100 had failed and taking advantage of an offer I replaced drives, eliminated the high voltage power supplies and simplified scheme.

In the workshop we have the complete electrical and mechanical schemes, but by now the electrical system has been completely redone.

This is the cabinet today.
