I too have had nothing but trouble with the latest ‘Lulzbot Cura’ software and had my printers on Craigslist until discovering this post. THANKS TO ALL FOR YOUR HELP as I’m printing perfect again!!! The key for me was to uninstall ‘Cura Lulzbot’ and clear the cache and then convert to ‘Cura 21.08’. I have wrecked PEI on a mini, maybe damaged a head, and can’t get the Aerostruder to work.
Here’s my story…
I have owned a Tax 6 since November 2017 and the Mini for the last month. Just by accident I started out using the ‘Cura version 21.08’ (MacBook 2017) from day 1 and have NOT had one single issue with it. However, when I installed software on the kids Macbook for some reason I installed Cura Lulzbot 2.6.66…easier to find on website. In retrospect all three computers with the ‘Cura Lulzbot’ version are a mess. Especially the Airbook that runs my Mini. I have had the following issues; interrupted prints, leveling failures, Z-axis issues, and dry extrusion. Erratic extrusion seems to be the biggest issue. It seems like anytime I use a setting other then the “standard” it turns into a huge mess. It looks like it may retract too much during leveling but what do I know. I was super excited to use the Ninjaflex with the new Aerostruder. I had huge hopes it would fix everything, but I give up and I’m going to try and return it Monday.
For the last 2 days I have been using the “Cura 21.08” exclusively on both printers and the prints have turned out perfectly each time. The only problem with Cura 21.08 is sometimes it locks up in the middle of the print. The good thing is the print is fine. I just ‘force quit’ and restart and it’s all good.
Now, my employer has multiple Taz 5 and 6’s and I also noticed that none of my prints turn out there…guess what? My work computer has Lulzbot Cura on it!!
Question: Does anyone know if Cura 21.08 will be upgraded and supported in the future? Right now it doesn’t support the Aerostruder, which is a huge bummer. Also, I think I have to be done with the Lulzbot version…I think I have over 80-90 hours into figuring it out and I’m exhausted. I did everything tech support asked with no improvement (uninstalled, cleared cache, upgraded firmware, etc, etc). It looks like Ultimaker now owns Cura or something…true? Anyone have an Ultimaker and do you like them? I am thinking about buying a couple more printers and want something that will be supported.
