I’ve been using a Printrbot Simple Metal for the past year and want to move up to a larger printer and have been looking at getting a Taz.
I have a feeling that the Taz 6 may be worth waiting for, however and can get a Taz 3 for ~$700-800 in good condition.
Are the improvements in the Taz 4 and 5 that significant that the Taz 3 isn’t worth getting? I’m not printing anything that requires ultra fine resolution. My understanding is that the big change from 3 to 4 is that they changed the Z axis from threaded rod to lead screws.
