Call it “only preference” if you wish but I must say I never liked how VCore centerfold pulley on one of motor and pushing with enormous force to motor first bearing. So I made one XY Motor block that places pulley between two bearings and attach it to motor through coupler of your choice.
And as addition I am using it also as fixing point for vertical subframe and it allows me to use longer Y rails because I don't need corner brackets in front of subframe.
You will need 8 pieces of M3 and 4 pieces of M5 heat inserts, two dowel pins 5mmx60mm, 4 625 bearings, two couplers 5x5 of your choice (for now I am using aluminium flexible) , and 8 pieces of M3x12 screws. And 4 “precision shims” 5x8x1mm will help.
And I suggest to make new M5 screws that do not have thread where idler goes.
But by all means do not consider it as “how to”.
