Hello guys,

I have a CNC machine 3020 and from the first day before 5 years I bought the Gecko G540 and until now everything worked perfect.
Suddenly yesterday I turned it on and without any load all the steppers are stalling when I trying to move them.
I didn't change anything in the settings, in the hardware, just turned it on.
I tried different settings in the tuning, very low to high but nothing changes.

I checked also the onboard parallel port and I have 4.7V.
My power supply is a regulated 36V 11A and my steppers are 1.8A/Phase.

Do you think that maybe the problem is the power supply? It can't give enough current now?

Thank you very much in advance.

Kind Regards,
Nikos
