I have a Lulzbot Taz 6 that I don’t use very often. I got it back in I believe 2018. I previously had the single print head, and I wanted to do the dual-head update so I bought the v3.1 dual head the other day.
Previously (back in 2018 when I got this) I remember I had a problem where I could not get the computer (I use Linux Mint) to recognize the TAZ6 when I plugged in the USB and tried to connect with Cura. I ended up just doing my slicing in CURA, and then copying the gcode file to a little SD CARD and then putting it directly into the printer. This worked for years.
Now yesterday I had to install the dual head and I had to update the firmware. I downloaded the newest version of CURA from the site first. Before trying to update the firmware I went into the LCD screen and took pictures of the E-steps number with my phone as they ask you to write it down before updating the firmware. Once again, I could not get CURA to recognize the printer. I would click connect and it could not find it.
I ended up using a different laptop with windows 10 to install cura and I was able to connect with it just fine. I updated the firmware that way.
I seem to remember somewhere seeing something about a fix for this, but I should have taken a photo with my phone on what to do. I can’t remember what it was for the life of me. I tried searching again and can’t find it.
