LR4 JP3 stepper motors unresponsive

so had my lr4 working well. disconnected the jp3 to install the permanent strut plates. once it was back together my end stops weren’t working. seem to have sorted out that issue but now the stepper motors won’t move at all. they all have power when the machine is powered on.
i’ve tried reflashing the firmware but keep getting an error asking me to try a slower speed.

any help greatly appreciated!

this is the error log:

What does $ss output from the terminal?

Thanks for getting back to me. Woke up this morning and the machine seems to be working! But here is the output incase anything jumps out at you?
