I will post some updates when i finished the next steps

Always nice to hear that someone likes the work, Thanks

Thanks a lot for helping
So… my question is: when do I need to change my firmware?
In all the resources I have been through I have been informed that I needed to secure that the connection between LinuxCNC and the mesa card (hostmot, hm2_eth and bitfile) all were in place and functioning correctly.
The ping OK was not enough.
Do I still need to do this or can I carry on?

Is there any hal to configure this 2-mode configuration!

 

Yes.  This post has a configuration using a step/dir spindle drive to manage spindle, orient, and c-axis modes:

github.com/LinuxCNC/linuxcnc/issues/3556

A few posts down the author attached a configuration zip file.

It's not extremely complicated, but neither is it simple.

And the issue reported in the post is still present.  I'm almost done with my attempt at a configuration based on the posted one, and I'll be testing if the joint.N.index-enable signal is what causes motion errors.

Good info.

What are the compression fittings you are using on the trucks? That is usually the more difficult part to source due to the odd pitch of 0.75 on some LM blocks.

For a lathe I would need 10 remote ports if direct fed like on your setup. That might be okay.
Equal length tubing may be a solution to avoid metering units if running it off a manifold. Any experience with that? 


 

A search for "M6 x .75 grease fitting adapter" resulted in a bunch of hits on Scamazon for 4mm tube compression fittings (both elbows and straights).

They aren't as cheap as the push to connect, but if you're worried about it you should be able to fully plumb up the lathe for appx $100 (20ftgs and tube)

Since mine are individual, I wasn't concerned with metering.  A pump or two and watch for some grease to ooze out of the truck or ballscrew before a long, slow warmup cycle to spread things out.  A manifold, metering components, or similar was just going to be a complication.  Once they are easy to access it's not a burden to lubricate.  And grease generally stays put for quite a while - no need to grease every day like an oil system.

So this is just another USB to serial implementation ?

Yes,
it's the usual USB/serial converter that anyone can make themselves.
Can you give me some working and usable examples?
I haven't found any, and I've probably wasted six months of my life trying to figure this out.

You have setup 2 networks on the same 1'st physical network card, the 2'nd network card has nothing set.
WHY????
That will not work, so start new and use this:
forum.linuxcnc.org/27-driver-boards/3559...ethernet-mesa-boards

We need a GUI with that industrial design !!!
Looks very ... industrial..
I like it.

missing L in "isocpus" may also be a reason...

Forgot to mention, 7i97T = 7i92T + 7i77
So everything there is valid for your board.

But will it make any sense at all to try to configure the setup as long as I get an “unsupported board”

You should ignore that, it is the older version of mesaflash, you do not need mesaflash at all unless you need to change the board firmware, ever.

As for "easy as...", it is same as everything in life, i can not use an iphone and will never ever learn as it is absolutely not intuitive, but i can operate medical equipment i have never seen before after about 15 seconds of looking at it.
Friendly advice, stop thinking about "mach vs LinuxCNC", they are not the same in any way, shape, or form, except both control machines, Mach is for small simple weekend use machines, LinuxCNC for everything from small engravers to huge industrial machines and fully automated production lines, hence it is simple only for simple machines, it can not be simple for a several ton industrial machine.
Get over it, move on, and start here first and foremost and do not skip anything:
forum.linuxcnc.org/10-advanced-configura...to-example-mesa-7i77

All guides say that grub is updated from this file by " sudo update-grub".

What worked better for running my real machine is to use this script here:- forum.linuxcnc.org/38-general-linuxcnc-q...rq-affinity?start=60

THE

New builds for a dentist, needed 3 of proper PC's for the new offices, but insisted on plain simple cases, will have to switch of the LED's before sending them as he might have a heart attack!
They do boot fast though, very fast:

Will do the boot test on Linux as it should be even faster...

I will need an ice cold shower if they call and say they can not ship it due to ....reasons!!!

Had several cold showers back then as even their CEO called me to justify their f@kin mistake, aft6er about 20 phone calls i had enough. They did offer to send me the motherboard that the EAN number was listed instead, but i said no.

So this is just another USB to serial implementation ?
