Physical buttons to 7i96s+7i77

Category: HAL

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.

Considering a Full Rewire on a Working Schaublin 125 CNC

Category: Turning

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?

Considering a Full Rewire on a Working Schaublin 125 CNC

Category: Turning

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.

Considering a Full Rewire on a Working Schaublin 125 CNC

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.

Considering a Full Rewire on a Working Schaublin 125 CNC

Category: Turning

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.

Can you please show the last say 30 lines from the syslog after you tried to start linuxcnc.
The ethercat master writes errors there
Output of "sudo dmesg | tail -30"

I had no idea Brother made CNC machines!

I thought they just made printers.

Servotronix Ethercat problem

Category: EtherCAT

Hello everyone, I have a small problem. I have three VEICHI drives connected via Ethercat in my system. My task was to connect a fourth driver to them, but from a different manufacturer (Servotronix CDHD2S). I purchased this driver, and everything works fine with the PC. Then I connected the driver to the common system with the other drivers via Ethercat, configured it, and added vid and pid. As a result, Linux CNC starts, but the driver hangs in an error and does not switch from PREOP to OP. Please advise what the problem might be. I am attaching my configurations and the xml from the driver manufacturer.

Physical buttons to 7i96s+7i77

Category: HAL

..in connection with the machine retrofit #338210
, I would like to include the hardware buttons in the configuration, also calculating the mpg. I have a lot of free inputs (all on 7i96s) and about twenty on 7i77 where I left the first three free as I understood that they are analog because of the potentiometer) now I need a suggestion, since dont have schematic for the old controller and not for the buttons, I think they are all on 24vdc including mpg. the outputs that I connected to 7i77 lit the bulbs of these buttons at 24v. should I try the configuration in terms of the mpg pendant for selector increments and mpg, and for spindle and feed override how should I connect? Thanks

Converting a Brother TC215 to LinuxCNC

Category: Milling Machines

Hello everyone,

I’ve been lucky enough to be the recipient of a Brother TC215 midway through a LinuxCNC conversion. I’ve always wanted to try my hand at CNC work, as I’ve done a little bit of manual milling and a lot of fabrication work over the years, and I’m always curious to learn and build new things. It’s been a pretty steep learning curve, as I’m new to basically all of this, but I’ve leaned a lot via search and previous forum threads and I think I’m at the point where starting a thread is worthwhile. 

On the hardware side: 
  • Mill is a Brother TC215
  • Dyn4 AC Servo Drivers/motors
  • Mesa 7i92 / 7i76 / 7i77D control boards
  • HP Elite 8300 USDT running LinuxCNC / ProbeBasic
I'm currently planning on running some of the older Brother boards for things like coolant, safety switches, limit switches, etc, just to keep things simple for now, as I already have breakout boards for all the connectors. I can clean everything up later if it gets that far.  My friend validated that the mill’s mechanical functions are in good shape and made it about halfway through the wiring - but my current priority is to wire everything up such that I can get XYZ servo movement first, and then I will add additional functionality. So I’ll try and keep this thread focused on the help I need to get things moving under their own power. 

What I’ve got so far is: The hardware is mounted in the mill, I roughly understand how things are laid out. I feel like i have a broad sense of how this should go together, but the details are oftentimes a little more opaque than I’d like.  What I’ll be doing when I have a minute :
  1. Test all my servo controllers and drives (easy to do, just need to get my windows laptop out to the mill)
  2. Power up the Mesa board (pretty easy, just need to spend some time looking at all the wiring and make sure I don’t fry anything)

The thing that’s blocking me right now is that I don’t really know enough to confirm that I’m wiring the servo drivers in a reasonable way. My understanding is: I should be able to wire my X / Y / Z servos in the following way, to do analog +10v control as a simple starting point. I need to set it up so I’m wiring: 
  • 7i77D +24v from field power to Dyn4 JP4-15 (Servo Enable) 
  • 7i77D TB5 (Analog Drive Interface) To Dyn4 JP4-13 (Analog +10v) & JP4-25 (Analog GND)
  • 7i77D TB3 (Encoder 0-2) to Dyn4 JP5-2 through 8 (Encoder outputs)


My plan was to disconnect all the motors from the mill and test them on the bench, but running through LinuxCNC, so I can confirm my understanding on how LinuxCNC operates. Once the motors are confirmed to work on the bench, then I would start on wiring up the Estop, limit switches, and other things I would need to get the mill safely moving, and then follow that with wiring in the spindle.


Here's a picture of how things it sits:


Any and all feedback appreciated, as well as suggestions about if I should approach this another way. I've learned a lot here and I hope that documenting this in the long run helps someone else :)

Probleme beim Bohrfräsen

Category: Fusion 360

Guten Morgen liebe Leute !
Ich möchte euch Heute von einem Seltsamen Phänomen berichten und bin gespannt,ob schon jemand dieses Problem hatte ,oder gar einen Lösungsvorschlag.   Der Sachverhalt ist folgender : Ich habe eine Platte in Fusion 360 Konstruiert, mit unter anderem 6Stk  8er Bohrungen,die zuerst im Bohrzyklus Gebohrt werden und nachher eine 13mm Senkung für den Schraubenkopf durch Bohrfräsen erhalten sollen,alles im selben Setup. Ganz Simpel,schon tausend mal gemacht,aber diesmal will es partout nicht Funktionieren !  Der Fräser will die Senkung 10mm in X Achse versetzt machen ! Wenn ich dann den G Code für den Bohrzyklus Lade,dann fährt der Fräser aber genau an der richtigen Stelle ins Material. Habe schon vieles Probiert,anderes Werkzeug,neues Setup mit genau dem selben Nullpunkt ect alles Erfolglos.  Ich werde als nächste ein neues Setup erstellen,mit dem Nullpunkt in der ersten Bohrung,die ja im Borzyklus Korrekt angefahren wird... Nächste Woche werde ich dann sehen. LG
