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?
 

THCAD-2 two pieces just ordered. Regarding CPC port: are we talking about Hypertherm Part Number ‎428653?

However Equatation 40, i dont understand the first greek character, and the name of this character.

The greek letter is 'kappa' and stands for curvature

someone has probably done it:


I have now also ordered some to try to integrate them into RIO

inverting the SSR output will work _BUT_ it will not have the desired effect
because after a LinuxCNC fault or before LinuxCNC is running, the drives will
be enabled.

If you cannot invert the _DISABLE_ function on your drive, its best to logically
invert the signal externally, one way would be:

+5V --> 47 Ohm 1W --> All drive _DISABLE_+ inputs
GND --> All drive _DISABLE_ - inputs

7I96S OUT0+ --> All drive _DISABLE_+ inputs
7I96S OUT0-   --> GND

 

[/code]

 

still an error

I've been considering this basically hostmot2/lbp16 over EtherCAT so the driver is pretty much the same
(just using Ethercat for transport)
