what is difference in AMAT30LV R8 and VM32L R8

just engine and belt or ?
i want to get something larger from 20 size but smaller from 45 size
and pm30/ama30/vm32 are there in between , by looking specs

so ama30 is same like pm30 is this vm32l from amadeal same ?
just upgraded to belt and stronger spindle ?

wonder so i can get cnc kit for pm30 cause they sell only kit for these

or make conversion parts buy rest and go after some of load of pm30 videos how to ..

plz help
thanks

oh if i'm on good track (that is same mill) which conversion u suggest ?
i like linuxcnc option even i never use one vs mech3/4 with all problems they got how i read

well shop just tell me these 2 are from 2 different factories so ,,,,
oh well will go with r8 amat30lv with belt and brushless then
anyone know where i can find files for upgrade for pm-30vl-/-amat30lv ?
