Hi everyone. I tried downloading Robbbbbb's config but I didn't have any luck. I have tried following the 2 pinned guides as well as all the steps posted in this thread, but I can't seem to get anywhere. I just have a single lichuan servo and the EK1100.

One thing I noticed is thatchanges the state of my Beckoff EK1100 instead of the servo drive. By changing p0 to p1, I can change the state of the servo drive to init (1ry) and preop(2ry) but nothing else. I tried changing some zeros to ones in Rob's config but it didn't work. 

I have also heard people staying they did stuff using twin cat, but I downloaded it and did some quick googling but I didn't get anywhere. 

Is there something else it could be? Could I have missed a step 

Thank you in advance

I can't seem to find a clear answer on the difference between the AC servo motors we use to power our machine axis ["AC servos"], and the 3 phase AC motors we often see on spindles run with a VFD. Can someone help me understand? 

I'm trying to figure out if I can power a Fanuc 22P AC Spindle Motor [3 phase, 4 poles] with a suitably sized Allen & Bradley Ultra 3000 [Model #: 2098-DSD-075-SE]. Is it possible? 

The application is a Hardinge Conquest retrofit, live tooling. I need to get decent positioning out of the spindle rotational axis to then lock (external lock, disk brake type) for cross drilling etc. Ideally I want to move towards full C axis but I think it wont be possible with this motor - correct me if I'm wrong. 

Thanks! 

Nice work/contrib. Useful.

If you decide to take it a level up one of those day, shout out and I'll put up the metric Tol & Grades EQs pub domain for internal and external threads. Not utterly complex to do imperial too, if required.

Any chance you can share the whole configuration you have shown in your post a couple pages back? That looks pretty good. I've been pecking at a Flex UI for a bit but haven't gotten very far yet.

I don't think I have it anymore. It was based on Persei8's QtDragon version but when the plotter stuff is all working I'll modify the standard QtDragon UI instead.

I think you should be using the current version of the source to start with
github.com/linuxcnc-ethercat/linuxcnc-ethercat

Only do this if you want a very old prerelease version. Best way is to follow these instructions which will give you the lates 2.9.3 release
linuxcnc.org/docs/stable/html/getting-st...th_preempt_rt_kernel

Finally got a chance to revise the code. This version adds tool number, spindle speed, and coolant to the previous version with Acme threading..

Enjoy.

I found a fix!
I'm running Debian Linux. Go to Settings - Display
Under Scale, pick Custom, and set X & Y to 1.1 See attached photo.
After that, the display fit on the screen!

Mesa should have 7I84s in less than a week, and our
distributors maybe a week later.

Found this vid:

In the comments the author discusses replacing the XZ motors, but keeping the main DC spindle motor.

Might get some ideas - other than using Mach, of course

Regarding the extra expense of the available Mesa cards... I don't know your situation, but that amount of money seems pretty trivial to spend on what should turn out to be an amazing lathe.  I know you'll spend more than that on just a few tools.

As for the 7i74 vs 7i84D... Small DIN-rail solid state relays are getting quite cheap (no flyback diodes required) to flop your output signals.

Yes I'm pretty sure they are analog input driven.

I'm planning on using the 7i97T with another card for more I/O. Was planning on using a 7i84, but I can't find them anywhere in stock. I need 20 sourcing outputs and 25 sinking inputs in total.

I could use some relais to convert the sinking outputs of the 7i84D to sourcing ones, but that seems unnecesary complicated. Other option would be the 7IA0 or the 7i77 but they are both 150€ more expensive.

For the controller I'll probably use a Raspberry PI 5.

I'm not personally aquainted with those drives, but a quick internet search makes me think they're analog-input DC servos.

Hopefully someone with more experience will jump in, but you could probably take your pick of with re-using the drives with an analog Mesa, or switching to modern AC servos (with analog, S&D, or field-bus/Ethercat).

Nice lathe, by the way.  You'll be giving RotarySMP's Schaublin 125 a run for the money.

No, even at high baud rates, serial is just not fast enough.

Cakeslob is spot on.

The latest firmware that supports the NVEM / EC300 and EC500 is this repo.

github.com/scottalford75/Remora-RT1052-cpp

The version you have used is very old original firmware and it didn't have the configuration upload capability.

Latest firmware is github.com/scottalford75/Remora-RT1052-c...ora-rt1052-3.1.3.bin

I've took it from here :
github.com/scottalford75/Remora-RT1052/tree/main/firmware

There is a firmware mentioned by me and it looks like it's been made for nvem board. Scott could you please explain which one is correct for nvem boards?
