Thank you for the feedback. I ordered some shoulder screws, unfortunately the real fitting screws (ISO 7379) are apparently only available starting from 4mm. Got some 3mm steel rods which should have much tighter tolerances to compare too.Quote

The pulleys have two bearings each so should not "tilt" as they turn. If they are tilting, it is likely that the shaft is too small in diameter. You should probably use either a 3mm steel rod, cut to length, or get shoulder screws that have 3mm diameter shoulder. You will find they fit tightly in the pulleys and do not allow them to tilt.
I will try using temporary spacer for positioning in the T-slot - thanks for the idea!Quote
As far as alignment is concerned, that is best addressed by designing the parts to put the pulleys at equal heights and spacing everywhere. If the vertical position is a function of where you position the parts along vertical t-slot members, you can make a spacer from wood or metal and use it to set the positions of the pulley mounts using the bottom or top of the printer's frame as a reference.
