I am getting very close to buying a new printer and the TAZ 4 is on the top of my list.
I do have a few questions about it before buying.
What kind of smooth rods does it have (Chrome Hardened, Stainless, just hardened…)?
Does it use linear ball bearings on the smooth rods or are they plastic sleeve bearings?
What electronics does it use and what firmware?
It does use ACME threaded rods for Z axis correct?
I have been printing for a little over 2.5 years now and I just want to see if upgrades will be needed out of the box or not, after upgrading my current printer from cheapo ball bearings and just hardened rods to good bearings and chrome hardened rods I feel they are a necessity for a higher end printer.
