I think the tricky part  with feed override and spindle speed override
is to get along with the GUI

yes, I knew about the 7i96s, yes, I had connected two independent ones when I had a lathe that worked in sync... here I will find an example for one via the axix selector,as a pendant I think it's not a problem. My problem is that I don't know how to connect potentiometers in the hall (if the first three inputs in mode 3 are analog on the 7i77?) how can they recognize it in the hall as spindle override and feed override?

hm2_eth: ERROR: Could not retrieve hardware address (MAC) of 192.168.1.121: Resource temporarily unavailable

Means that there is no communication with the 7I96S

If you search the forum for "MPG" you will find a number of examples

The 7I77 has 2 MPG inputs (4 pins) and the 7I96S has 4 MPG inputs (8 pins)
Either will work wit 5V to 24V signals

Yeah, I was amused to discover the same!

Thanks for the link - I was hoping he'd have some wiring guidance, but he never ended up getting the mill.

What I really need to proceed is to be confident that I'm not going to blow something up by wiring the Mesa board to the servo in the described fashion - it appears from reading the manual that it's fine to wire it as "Analog Circuit D", on Page 18 to the Mesa driver pins, and I'm assuming that I can then also wire up the JP5 Encoder output to the Mesa Encoder pins as a "Line Drive / Reciever" as on page 20. Once that's done, it feels like I could set up a basic LinuxCNC HAL / INI / PnCconf setup to power and move the servos.

I can also call my friend who has his setup and get him to walk me through his setup and emulate that, but I like to know how the system actually works vs just emulating other people's configurations

So the plasma_gcode_preprocessor which comes with Monokrom works for you? I still had no success.

Hi guys!

 I managed to stop my LinuxCNC from giving errors by isolating a core of my CPU. Since then, the milling operations have not stopped and everything is going well.Now I need to add a 2-axis rotary table.

I copied my working configuration from my Mesa 7i96s, and added two A/B axes, both in the INI and in the HAL.I thought it would be as simple as that, but I'm getting an error.I'm not sure if the axes should be called A/B in the configuration.I'm attaching the files to see if you can help me.

Thank you. 

2.9.0. I didn't have a 7i92 with me, so I used a 7i96s as the main card, which turned out to be better because I'm planning two additional axes later that will use steppers...now about mpg, maybe and I have an example to try...but I didn't have any experience with connecting potentiometers for feed and spindle override, and any Hal example would be valuable to me.

Thanks for the suggestion. Do you mean sticking with the Mach3 system, or keeping the existing wiring even if I switch to LinuxCNC? One thing I’m worried about is not really understanding what is what unless I take everything out and redo it. “Just” cleaning it up and making it look more organized would definitely be possible, but wouldn’t I just end up with a nicer-looking system that I still don’t understand any better than the current one?

I know the instict is to just rip it all out and start from scatch, but it might make sense to replace things in parts.

For example, I found 50ft.of 2 wire 18AWG cabl in a random cupboard, which I later used to connect my stepper drivers to power instead of the original 14AWG wire which was too short and too hard to bend.

Maybe you can preserve the existing wiring, but cut, cable tie, and twist it for better cable management.

Keep the wire, preserve the connections, but make it at least semi-sane, instead of that total mess.

If you already have some extra light cable (22-18AWG), you can also use that to keep stuff separate, and also keep down interference a bit.

Hi,I recently got a Schaublin 125 CNC and I have a dilemma that I wanted to get some opinions on.
The machine was previously retrofitted with Mach3, and it basically works, with a few small caveats. But the wiring is a mess, and I don’t have any schematics or documentation at all.
I previously retrofitted a Hermle 1200UWF to LinuxCNC and really liked the experience. From my first contact with Mach3, I can’t say the same about it.Right now I’m thinking it would be very easy for me to just clean it up a bit, fix a few small issues, and use it as-is. But with wiring like this, it feels like I’m just waiting for the first small problem, and then I’ll be standing there rewiring everything because I can’t find anything in that undocumented mess.
I don’t want to speak badly about the previous owner — if someone other than me had to work on my mill, they wouldn’t fare much better either. But still, this has me thinking about rewiring the whole machine from the start so I don’t run into the same headaches later on.I’m a hobbyist, so it’s not financially important for me to get the machine running as quickly as possible. And if I’m rewiring it anyway, I would probably switch it over to LinuxCNC as well.
So my question to all of you is: am I insane, or is this actually reasonable? I have a working machine, and I’m considering taking it completely apart and turning it into a months-long, or even year-long, project.
Another reason I would prefer LinuxCNC is this forum. I haven’t posted much here in the past, but all of you were essential in getting my mill up and running. The fact that I was able to solve almost all of my problems just by reading here says a lot in my book. Maybe that’s true for Mach3 as well, but I somewhat doubt it.It may be that asking here is like asking a lawyer whether you need a lawyer, but still…

I have a number of pictures of the machine and the wiring, and a video I made, so you can get a better idea of what I’m working with.


Any suggestions on how you would handle this would be very welcome.

My Linux runs fine. It's just that the driver doesn't switch to enable mode, but the other three axes work. I think the problem might be with vid and pid.

What version of LinuxCNC are you using?

Why do you need a 7i96s and a 7i77?

Wouldn't just one suffice?

The 7i77 has 48 I/O ports, which should be more than enough.

How does the 7i77 connect to the PC?

Wiring the buttons, switches, dials, etc.to the Mesa is the easy part.

Configuring LinuxCNC to interpret the signals is the hard part.

Start with the simple buttons and switches (and E-Stop); then worry about the dials, which are more complicated.
