Like many I have an issue and Lulzbot Customer Service is unresponsive. I know they laid off much of their staff and are in a business merger but the complete radio silence is disheartening. That being said I am turning to the community to see if anyone has any ideas because wallowing over no contact wont help me
Background: Starting in january of last year I bought my first 3d printer a lulzbot taz 6. I had some issues with the first one (a leaky hot end) and rather than try to figure it out I went back to the store I bought it from and exchanged it. The second one I got ended up having other issues (Z axis wobble) and I exchanged it as well. In March I got my current machine. It has not been without its problems but I realized that no machine would be without issues and I managed to work through most of them with help from support. Given the last date of exchange I have about 2 months left under warranty ( If they become responsive)
Current Issue: I now have a new issue I have not been able to figure out. Starting about 2 months ago my Taz 6 has developed a vibration when moving the Y axis. It is constant that it vibrates but seems to be intermittent between moving front to back or back to front that produces the vibration. It happens both during printing and when moving the axis with the front panel controls.
I did a lot of reading online and searching but have not been able to locate much relevant help. The vibration appears to be toward the back of the axis. The smooth rods don’t have any noticeable markings or any kind of bend, though they do leave slight streaks of color from the self lubricating bearings and I will get blackish colored deposits, which seems new to me but I may just not have noticed before.
What I’ve Tried:
I have used Cura LBE to ensure the firmware is up to date.
I have tried cleaning the smooth rods with a clean cloth. I removed the Y axis thumb screws, unplugged the motor and turned the whole assembly over to ensure I could access the full length of the of the rods. Wiped them down well and reinstalled. It was fine for about a half a print before it started vibrating again.
So I repeated the step and added in checking all the screws for tightness and making sure the belt was snug. It seemed a little loose so I tightened it a little but made sure not to over do it. I also put a small spot of blue ink on the edge of the belt where it met with the pulley when the Y was fully extended so I could tell if it was slipping (it’s not). Put it back together and a half a print later it started vibrating again.
The vibration was getting worse as time went on but I could still get decent prints when I stick to the center. Then the strangest thing I have had happen to date occurred…
While printing a prop, the printer lost track of where it was somehow. It printed back and right of center a quarter of the way through the print. After some spaghetti it built up enough of a base to even start solid printing again in the wrong location… I have NO IDEA what could even cause this… or if it is in any way related to the first issue. I am adding it in here because it could be a puzzle piece to see the whole picture… or it may be completely unrelated.
So… yeah… Please help!
