Doh! I removed it when I installed ROME because it has to be set for each extruder so I just did it all in the slicer gcode. I'll put a token setting in printer.cfg. Totally forgot I did that thanks for the help.
I never got back here to report, but adding the pressure_advance setting to my printer.cfg unfortunately did not bring back the pressure advance display in mainsail.
So i just looked through the mainsail code. The only way the pressure advance options wouldn't show is if you don't have any defined extruder steppers. I guess ROME could indeed be responsible for this @Helge Keck ?

After I define those macros then mainsail will allow me to see pressure advance for T0 or T1? I think I have to add pressure advance values in for T0 and T1 as well (in printer.cfg) but not sure what the syntax should be.
