Anyone know which pin is PS_ON??

Thank you
searching bit better seems should be fine declaring D11 as PS_ON and connecting https://github.com/makerbase-mks/MKS-GEN_L/blob/master/hardware/MKS%20Gen_L%20V2.1_001/MKS%20GEN_L%20V2.1_001%20PIN.pdf at the bottom right, just over the D21 highlighted in red, maybe i'll try and update this thread
