Matt from 3DXTech here. We have two M2's - one with the v4 hot-end and the other modified with the E3D v6 all-metal hot-end. Both are excellent machines and can handle basically anything we've thrown at them (like the subject line said - PLA to PEEK). The v4 is very nice and prints pretty much anything we've thrown at it that processes under 300c. The other M2 that has the v6 holds steady at 400c and we use that one exclusively for high-temp / exotic filaments.
We have 5 other printers, but these two are our go-to workhorses. Hats off to MG!
