"out-inverter-1" should be: "pin-01-out-invert" (in the title)

Try setting pin-01-out-invert to 0 instead of 1.

Perhaps 1 is the default value.

Check all the HAL files in case the stuff in another file is messing stuff up.

video     That's what I did when I ran into the problem

Weird.

Try creating a new config with StepConf and look at the HAL file(s) it generates or look at the hal file(s) in an example config to make sure your syntax is correct.

2.9.7 I can't manage to start a configuration with inverted output ports.

pin 1-14-17 out-inverter-1 seems not to work

I can change state, but I can't start a setup with an inverted state

Unfortunately, in trixie image_2025-11-10-raspios-lcnc-2.9.7-6-trixie-arm64.zip the command mesaflash --device 7c81 --addr /dev/spidev0.0 --spi --readhmid doesn't work. No 7c81 board found.

Attached should be the config for that board.

Danke. Werde ich mal ausprobieren.

High-pitched noises drive me insane.

I can hear higher frequencies than most (I am young).

Nobody else can hear them, but I can!

understood, thank you.
I will look for tutorials as i'm beginner with this technology

Perhaps MESA will replace/repair a broken board for free?

Never hurts to try.

I have an extra SUNIX PCIe parallel port card that has never been used, though shipping is the issue.

Not sure exactly how that works. TIM2 and TIM5 share things, at least encoder pins, so only one encoder.
Maybe there can be TIM2 on one pin and TIM5 on the other for other purposes, not sure.
You can always do some surgery. Prototype in free-run mode and you don't need sync0 and sync1 which are
on TIM2 CH1 and CH2, so you can free them up and use them for encoder input for the 32-bit encoder.
Solder on tiny wires and melting glue. Has happened before.

Perhaps increasing the driver supply voltage will improve high speed performance and ensure lost steps don't happen.

If you want the accuracy to be greater than that of the encoder, I don't think your encoder will be of much help.

High-precision stuff is metric, please use mm, even if you are in the US, though if your whole system is imperial, I guess you have no choice.

A picture might be nice.

Please also post some system info (LinuxCNC version) and your HAL and INI files.

Ok Thank you

Normally this is what is needed to read Mesa boards:
mesaflash --device 5i25 --readhmid
but for SPI i would guess
mesaflash --device 7c81 --addr /dev/spidev0.0 --spi --readhmid
should work, and it should be safe to try.
If you do have more questions about Mesa boards, use the "driver boards" section of the forum.

After looking at the arm64 Trixie repo it appears there are no packages available for mesaflash.
One option would to be build from source.
Or to manually download the bookworm version and install that.
As it is almost 12:00 am I fear I may not be able to respond in a timely manner.
