I have bought RPI5 for performance boost. But Remora is not working on RPI5.

Remora does not yet support RPi5 with SPI, nothing supports SPI yet with RPi5, because it is different than previous versions

Oh no. Again my mistake, not reading or searching enough before buying rpi5. I bought it exclusively for remora-spi.
Can I try rpi-ethernet hooked to octopus 429 board with spi-ethernet w5500?.
Is there any chance of getting spi working?
I you guide then I might look into code and try at my level.

At my skill level, the w5500 ethernet is closer than rpi5 spi, because I dont know how to do the spi thing.
Both will be supported in time, ill see what i can do for you with the ethernet, but the rpi4 spi is the most stable supported option so far.

Yes, I have gone through searching and found that its much easier to go ethernet way for RPI5. Due to lack of support and documentation for RP1 chipset. It might only possible when RPI and LinuxCNC guys both support this.
Can you guide me how can to make w5500 working for 429 since you have already made it for 446.
"I seen the official LinuxCNC image for RPI5 and its stated that its for SPI and Ethernet. So I bought rpi5. But after installing official image I found its not working. Later in forum I found SPI working was wrongly mentioned."

Can you guide in using generic mpg pendent with remora-spi?
I tried with using digital-input pins. It was kind pf working. But there is limitation of 16 input pins in remora, so i cant use jog for all 5 axis. And I got only x1, x10 working not x100.
Then I tried to define encoder pin. PV.0 but then same float and s32 pin type mismatch error. Using latest 9.2 stable version may that is giving this error.

Are you trying to use the encoder with your mpg thing? post your halfile
for the rest of the mpg, i dont have a good answer.
personally i plan to do something like this with the hal_gpio module for the rpi
community.carbide3d.com/t/cncjs-handwhee...owto-for-nerds/18726
linuxcnc.org/docs/stable/html/drivers/hal_pi_gpio.html

Here is my mpg.hal
As per linuxcnc example "addf encoder.update-counters servo-thread" should be base thread, If I use base thread it gives error.
This HAL is working on my pendant. But signals are lagging, if I change scale then it reflects late. If I release enable switch then also axis remains active for few seconds.
I have defined all inputs as normal digial inputs and its working. (There is limit of 16 digital input) so I want A,B defined as encoder input. This way 2 more digital inputs will be saved. But If I define A,B pins of encoder as encoder input remora.PV.0 then HAL gives float to s32 type mismatch error.

# If your MPG puts out 1 pulse per click set x4 to 0
setp encoder.0.x4-mode 0
# For velocity mode, set to 1
# In velocity mode the axis stops when the dial is stopped
# even if that means the commanded motion is not completed,
# For position mode (the default), set to 0
# In position mode the axis will move exactly jog-scale
# units for each count, regardless of how long that might take,
setp joint.0.jog-vel-mode 0

Few more questions.
How to use hardware buttons for ESTOP and machine enable buttons.
I have defined ESTOP button as per your config and wired button accordingly. But its not working.
Why I cant move any axis faster than 650mm/min?

I like that you arent doing the normal configuration, it keeps me sharp. But since you are doing unusual setups it may take some figuring out
ok, lets start with the encoder
this is your working (but slow) config yes?
theres a few things I think are happening here. linuxcnc doesnt use the same encoder as remora exactly
you need to download and install the remora encodeer unit and remove your other parts that ref the encoder
github.com/cakeslob/Remora/tree/main/Lin...omponents/PRUencoder
ok, so thats the first part. set that up, and test your encoder using halshow. once you see your increments showing up in halshow under remora.pv.0
then we move on to the next thing
the remora encoder outputs as a float but joint.0.jog-counts is asking for an s32
linuxcnc.org/docs/stable/html/man/man9/conv_float_s32.9.html
looks like you need to feed your remora encoder count, into the conv-float-s32
this should change the signal, to s32 which should work with the jog counts
damn man you are making me work for this
