Mach3 -> Camtronics -> Parallel P Replacement

To be perfectly transparent here, I actually had to look up qtvcp.. That's how shallow my knowledge of linuxcnc is right now.

Not really a necessity, I just threw it in as a convenience, for those that wanted\need it.

I checked the BIOS on this ZBOXNANO-AD12 PC and its as up to date as possible. Version 2K131128.

Ahh this is a relatively low powered PC, the Ethernet performance is probably more related to that than the
Realtek driver (which I have not noticed any real issues with)


What does

latency-histogram --nobase -- sbinsize 1000

show?

Right so there's considerable native jitter being added to the ping times

Here's the same plot from the system with the ping times I posted:




Note that that has isolcpus=3 but that does not make much difference on this machine

Is what I am building on projected to be a problem down the road for a 3 axis config?

You are moving slowly towards the deep end !

It should not really be an issue, worst case is that it cannot do a 1 KHz servo thread, but 750 0r 500 Hz is OK for most
applications

I dug another system out of the basement.
