So a few months ago I traded in my Mini for a Mini 2, which I was so grateful that LulzBot offered. However, I have finally started to get my Mini 2 up and running with its intended goal to run the SL head permanently (no more swapping it out on my Taz 6 and all the steps that takes).
However, as I have started to print with it, I’ve started to see some growing concerns of mine, that I am no longer brushing off as “normal” or “my fault”. While I was told the noisy steppers (they make a loud static like sound when not moving, but not disabled) is normal, I feel these other two aren’t.
Originally I thought this was a normal issue. If I turn off the printer, or if the steppers are disabled, the left side of the x-axis drops down, making it no longer leveled. As I mentioned, I thought this was normal, but, as I started to read about another issue on the forums, I’m quickly realizing it’s not. Can someone offer some advice on this? Am I right to be concerned this is indeed wrong?
First Layer Uneven
The first level for me is very crucial when it comes to printing, and I will spend what feels like hours dialing in my settings to get that perfect smooth first layer (sadly this has become almost impossible with the changes to auto-leveling doing a double tap, still haven’t gotten my Taz 6 the same since). Well yesterday I started to calibrate my printer, getting it all lined up to use the SL head (e-steps and all), and realized that on my first print, the first layer was nice and smooshed on the left side, but on the right side it wasn’t. I could see the print lines.
Thinking this was just an issue with the auto-leveling being inconsistent (as I mentioned above it seems to be now), I did another print, only to see the EXACT same effect. Now I know this isn’t the leveling just being off. I have read posts about this being an issue but they date back, and I’m unsure if it’s even been fixed. Note I am running CURA 3.6.20, so it’s rather new, and I make sure I clean my components between every print. With the bed and washers getting wiped down with isopropyl alcohol as well as the nozzle being cleaned BEFORE it’s scrubbed (heat it up, wide it down with a paper towel, same process I’ve used for year).
I could really use some help with this too as it’s rather frustrating. I would love to hear “oh that was fixed in later versions of CURA”, but, I haven’t found anything to support it.
To be honest if I learn these are still on going problems, it’s really making me question LulzBot and their designs. I used to praise them, but lately I’ve growing annoyed. With stories I hear about the Taz Pro, or what I have listed here with the Mini 2. Shoot CURA even gets annoying now with it magically forgetting settings I changed when reopened (or reverting an unsaved one … sometimes), or just switching profiles when I open it (or the fact it crashes if you load too large of a model).
