I changed it as you wrote. How else can I change it?

Haha i meant change remora.SPI-enable to remora.enable.
Here is the file as how I meant:

How did you comment on joint 3? Now it shows me a joint 3 scale not found error

I also took a copy of the flash before installing Remora but I could not get the board to work with Mach3 again after restoring the original firmware. I tried to figure out what the mystery chip was by decompiling the firmware, but to no luck.

Thanks for the work to figure out the mystery chip and as you say it must be a single wire EEPROM. Most likely used to give some form of feature enablement / protection. Maybe the number of axis that the board can have.Before I flashed the NVEM with the Remora firmware I created an image of the stock software also, so I have one if its needed. I did buy my board about a year ago and it says NVEMV2 on it so i believe it is a version 2 board, and I don't know how different they are.
I do have the mystery chip, although it is rotated from Scott's board and the power and ground pins are switched. The three connected pins are the same as Scott's diagram. Scott, when you tested the PA_3 pin do you remember if the ST-Link was connected? To be clear by connected I mean having pushed the "connect" button on the programmer, and disconnected meaning plugged in and powered up, but without connecting, or having pushed "disconnect" on the programmer. While the ST-Link was connected PA_3 stayed near ground, but when I disconnected the ST-Link I discovered a 3.75 Mhz square wave on the PA_3 pin. As soon as you connect the programmer the square wave stops, and it restarts on disconnect.
After the disconnect button is pushed or the device is initially powered on the PA_5 pin seems to go low for a short pulse, wait ~0.3 seconds, then host short burst of communication. The PA_4 pin goes low for this brief pause, and then returns high. This initial pulse (before the apparent communication) is when the PA_3 pin starts the 3.75 Mhz signal.
It appears that pin 5 is a single wire communication line. I'm not sure what it is but it appears to be high or low for multiples of 100 microseconds.
When I flashed the Remora firmware the signals all stopped. PA_4 and PA_5 remain high, and PA_3 remains low so whatever it is it's at least initiated by the processor. I'm not sure what to make of all this, but hopefully this will help.

@Domi I sent you an example, how hard can it be? You should really just use GRBL, I've explained everything so many time and you still don't get it

It is setup for 4 axes for a 3D printer. You will see in the INI file the config for 4 axes.
Over the weekend I'll upload my latest NVEM config (without spindle). as you found out the reference to SPI has been removed.
Great to see that you are determined to get it running, You are very very close.

Hi, have a look at the config sampleHow did you comment on joint 3? Now it shows me a joint 3 scale not found error

The error you were getting is caused by the HAL file not finding the corresponding parameter in the INI file. You need to maintain and align both the HAL and INI files for the number of axes you have..

Royka: I copied your file and kept making a mistake for joint 3. Probably because it's a mistake in the file.
Scott: Thank you. yes close and at the same time so far: D

scotta: yes that's what I meant. The 4th axis must be set in the inore fileThe error you were getting is caused by the HAL file not finding the corresponding parameter in the INI file. You need to maintain and align both the HAL and INI files for the number of axes you have..
