Hey everyone - someone gave me a lulzbot mini, and I’m trying to get it working to give to a boy on the robotics team I coach. I was told “it worked last time I used it”, which was quite a while ago. I have quite a bit of experience with 3D printing, but I’m trying to figure out how this one is supposed to work.
The book says to download Lulzbot-edition Cura. I did that (ver. 3.6.29) but it cannot connect to the printer via USB. So I found a forum post to try Cura 14.09. That one can connect, start a print, upgrade firmware, etc.
But I don’t understand this printer’s pre-print procedure. The user guide says this printer will tap each metal corner on the bed before the print, but using Cura 14.09, default install, it doesn’t do that. So I found some start gcode for a mini using a different version of Cura, 19.08, and it did the probing but it didn’t print properly. It did a huge retraction before the print, a series of wipes, then when the print started it wouldn’t extrude because it retracted too much I think.
So my question is what’s the best way to set this printer up? Do I need to use an older Cura or should I be able to get the latest one to work? If I use Cura 14.09, is there an official start GCODE I should be using?
