So… just unboxed my shiny new Taz 6, following the unboxing and setup directions very careful and was very excited and everything went well til I hit the Print button… it moved everything around like it was going to tap the first button to calibrate before hitting the edges, and had no issues at all moving around or moving down, and then it got very close (few mm away) and then began to grind. Badly. I was using Cura 19.12 and trying to print the first print rocktopus.
After cancelling/shutting off motors once or twice, I finally determined that trying to move up in the Z axis was the issue. I haven’t tried moving down because it’s very close to the bed, and x/y work just fine both directions.
I made a video showing it moving properly in the x/y directions but grinding when I tried to move the Z up – (at the beginning and end) of the video: https://youtu.be/6tiYM5v8PAA
The XYZ coordinates on the front of the Taz show that it think it’s moving in the Z direction, but obviously, it’s not. I did email tech support but it was right after they were gone for the weekend, apparently.
I saw this thread about the mini: https://forum.lulzbot.com/t/taz5-noise-during-z-homing/3459/1 but I don’t understand a lot of what they’re talking about and since it moved down without issue, I’m not convinced it’s the same thing.
Amazingly frustrated would be an understatement… if anyone has suggestions or thoughts, I’d love to hear them.
