Thank you for help. Everything works just fine. Xilinx was a bit tricky to download due to american regulations and policies. Somehow registration form doesn`t work correct. But finally I downloaded it today so this is first and last case.

Talking about original mesa cards, in my country it is almost impossible to get desired board on time. They simply out of stock. So I had to save 15$... I`m sorry.

Xilinx itself appeared an old nightmare for me to install. Heavy virtual machine, only Win7 32bit and 30-year old interface... I would not recommend customizing chineese boards after this experience.

P.S.: hope people who don`t help use Windows

Looking for a lathe encoder hal for for threading and rpm. the files I find say to use the index pin however its not an option for the el5101 

I tried riocore with a Tang nano 9k last year, when I first read about it. I loved the idea and I think you have done a fantastic job so far.
So a big thank you, although I have not done anything productive with LinunxCNC and riocore yet, mainly because I already have some Mesa cards that I use in my machines and not the time that I would like to have to start experimenting with a fun project with riocore. I love the idea that for simple projects I could potentially use riocore with a cheap FPGA board though, so hopefully I'll do this in the near future!

I have a project in mind right now though, that would ideally use a microcontroller for sending commands to the FPGA for driving two motors and I would like to know if I could potentially connect an ESP32-S3 or ESP32-P4 that I already have. I'm only familiar with Arduino framework so far and I tried to dive further in ESP-IDF in the past but that was more hard for my current experience. Do you think it would be possible and fairly simple to communicate an ESP32 board with the Tang nano over SPI, like your LinuxCNC driver does?

Okay, we will try to confirm that it is our servopack.

Does anybody have experience with position control mode on the SGDH-10AE or another Yaskawa sigma II series servopack?

FYI, when I ran my full configuration the vfd would work correctly at startup but would fail after several commands. Sometimes after homing, sometimes after MDI commands, but seemed to lock up and stop sending commands to the VFD. No errors reported in hm2_modbus and did not recover after set/clr the modbus reset.

I looked at git repo and saw several updates after the 2.9.8 tag. I have not noticed any lockups since installing and running the RIP master. I do get a few dialog errors about PDU too small while running but I don't lose control of VFD.

Hello everyone,

As most of you know, Stepperonline A6 servos have 17-bit multiturn encoders. 
Encoder cables with battery boxes are also available for these servos. The cables are supplied with batteries.
When these cables are used, the servos become multi-turn absolute value encoders and the reference run is no longer necessary.

Here is a step-by-step guide on how to set up the servos after installing the cables.

1. Switch on the servo.
2. Set parameter C00.07 > 2 (linear mode, absolute position).
3. The servo displays error ER20.8.
4. Set parameter F31.10 > 4.
5. Switch the servo off and on again.
6. Perform a reference run.
7. The .hal and .ini files must be adjusted.

I recommend commenting out the relevant sections.

Now, all you have to do is press the home button after switching on the machine, and all axes are immediately referenced.

That's it.

 

 


Note that to get 0 PWM at startup or watchdog bite you may need to

1. Chose the output polarity that is 0 at startup ( I think this is the - pin )

2. Invert the PWM output in HAL
