I would like to tune my drives a bit. What tuning have people tried? I'm not clear if the following command tunes the drives or re-sets everything. I'd rather not try at this point. I just let Linux do an update and had to re-install.

LC-E Series AC Servo Drive
5.2.1 Initialization parameters
Set P02-31 to 1 to initialize the drive parameters, and the drive needs to be restarted after the setting is completed.

Also, what are people doing for gantry (dual servos on a single axis) systems? 

Those drives will jump off that table is you get them started.

Now we are stealing this thread hehe
I bought most from aliexpress, and from a local dealer that carries a limited assortment.
Ax58100: vi.aliexpress.com/w/wholesale-ax58100.ht...0&sortType=price_asc
I hope that will give a list of several sellers, it does for me. Around 10 €/USD.

The crystal is a "passive crystal smd 25 mhz 3225", aliexpress have plenty dirt cheap
vi.aliexpress.com/w/wholesale-passive-cr...e=total_tranpro_desc
Any crystal with the "passive crystal smd 25 mhz 3225" spec will work.

The difference between the ferrite beads is laziness or something like that. They are the same.
I wrote out the full spec once, and not the other.
As for substitutes, any "ferrite bead 220 ohm 0603 1ln" will work.

 

Hello  5_Zylinder , hello everyone. I just bought a HURCO BMC 30 AP and I want to upgrade it to LinuxCNC. Could you please send me the documentation and the electrical diagram? Because I don't have any documentation, only the manual for the Yaskawa servo driver CACR-SR20BF12GE downloaded from the internet. I want to use the original servos and servo drivers and use mesa 5i25 and mesa 7i77 or 7i97. Is your machine working yet? If you could also give me your Ini and Hal file, it would be very helpful. Of course, I can appreciate it.
Thank you in advance.

sweet! let me know how it works for you!

if you are on the stable version it will not have the user_buttons feature yet if memory serves. that would be in the develop version for now only. you can leave it off and the pbsplash you can copy from the git directory if you would like that as the splash screen.

No, somehow I thought you had a 7I96S.

So is a 7I96 + 7I85 with one 7I96 stepgen (chan 4) replaced with PWM/DIR
and stepgen/encoder index on the 7I85 what you need?

Yes. I wanted to communicate via spi only. Since I also configured it in spi mode in daisy chain config in FluidNC. Remora communicate with LinuxCNC via spi. If possible I can send spi config data to tmc via some module in LinuxCNC. Or if you modded remora-spi source to suit tmc 5160
 

If you can make a direct SPI connection between the Raspberry Pi and the TMC drivers, then it should be very easy to adapt my code; all it does is sending the registers value to the drivers according to values you set via parameters until all the registers have been set, and then it reads the motor position. And another function sends velocity command. You'd just need to remove the write velocity part (or, simply said, not addf TMC5160.write) and not connect the position feedback pin. In theory you could still use the SPI line to get TMC status bit and be informed if one driver has an error.

I want to try to control the SPI device on the RPi without the use of BCM2835 library to avoid compatibility problems. Give me a week to try and I'll publish my code after that. I didn't even try to modify the spi-remora code, as this is way above my coding skills.

That was me, link is on page 1.

Glad you got it working.
I'm not really familiar with stepconf wizard but it may just simply have been overlooked when gmoccapy was added. Those wizards are very handy to get a simple working config but it's pretty much impossible to keep them up to date with the latest developments.
There usually needs to be some manual tweaking in the hal and ini files.

Thanks to "onceloved" problem is solved. My drive exposed EoE (ethernet over ethercat) and it was in conflict with CoE. I recompiled etherlab master with --disable-eoe option and the problem is gone.

the pin number on the config.txt file is "P4_17"

{
"Thread": "Servo",
"Type": "Digital Pin",
"Comment": "XIN",
"Pin": "P4_17",
"Mode": "Input",
"Data Bit": 17,
"Invert": "True"
},


I have to write like this in the .hal file?

# ---X Axis Inputs---
# X Home Prox
net XHome joint.0.home-sw-in <= remora.input.17

 

Awesome, that fixed it, your help is most appreciated  
Do you know why it would create pyvcp files when I selected to add the speed display when running the stepconf wizard, did I put a tick somewhere that I shouldn't have?
 

I have been working on your EaserCat projects for some time now and am impressed by your work. However, I am having trouble finding sources for some of the components you use. I'm having trouble sourcing the U10 AX58100 and the Crystal Y2 NXK25.000AE12F-KAB6-12. I just can't find a distributor. Can you give me a source?

I have found a dealer for the BLM18EG221SN1D components. However, he does not have the BLM18EG221S parts in his range. What is the difference between the two?

I have a 7i96. Is analog out available on a 7i96?
