When machine comes out of estop it gives error "Remora FATAL ERROR [JASON Config]: Config file open failed (status=0xA2)".

Thank you very much for your help.

Have you made any further progress with this?

If someone can give me example config.txt and config files hal and ini for skr3 board, it would be really helpful. Or look at my config files for skr3.

Champion!

Hi tommylight!

We have tested the spinndle idea but the error happens regardless of if its on or off. We use and unshielded cable, let me test that out.

Most probably interference on the SPI wiring, so the first thing would be to make those wires very short, like 10cm short, or use shielded cable.
I would also not bother with the power supply as Octopus has pretty good regulators.
If the machine has a spindle, notice if the error occurs when the spindle is turned on.

we turn on the machine, and all normal

## Entering IDLE state

we open linux cnc and enable the machine

## Entering RUNNING state

x ammount of time passes and this happens

## Entering RESET state
Resetting rxBuffer

disable and we then get this printout

## Entering IDLE state

after that we can enable the machine but the time it takes for it to enter the reset state is much much shorter, like milliseconds

Hello again Scotta!

We've continued testing on the octopus board, we have gotten movement but it seems that the SPI communication with the board seems to keep dying. We got the serial output:

This last bit is where we are running into a wall, we are not sure what is causing this.
