I've got a comparable sized custom kossel Xl, which calibrates to 0.006mm deviation. I haven't used a tevo LM but would quite like to, as I like the frame design a lot, it's simple and in theory the frame should be very capable.
Where they have cut corners as best I can see are the controller, the arms, the joints and using rollers not linear rails (this one really makes a big difference). How much play is there in the effector when holding in the homed position? How much do the arms flex? They're quite thin for their length carbon fibre or not. How similar in length are the arms? Magnetic joints really do offer zero backlash and if well made are all within 0.05mm length of one another.
Your microswitch should be accurate enough to get reliable probing.
If I bought one of these I'd change to linear rails, Haydn magnet joints, and duet wifi/ethernet.
