Lulzbot TAZ PRO won't connect to Cura

Brandnew Lulzbot Pro won’t connect to Cura via USB

Can you provide a little more info?

Which OS & platform (PC? Mac?)
Are you using the USB cable that was supplied with the printer?
Which version of Cura are you using (is this Cura LulzBot Edition 3.6.21 or 3.6.20?)

In Cura (assuming this is Cura LE 3.6.x) did you go into preferences and configure it for a “LulzBot TAZ Pro Dual Extruder”?

Hi Tim,

Windows 10 OS on lenovo P50

Cura version 3.6.20

Yes set it up for the Taz pro. Also tried to update firmeare but that would not work either

I normally use a mac and don’t have a Windows machine with Cura. But in Windows, can you go into the device manager to check your connected USB devices to determine if your computer can see the printer at a device level?

I’m also wondering if the upgrade process might be responsible. When upgrading Cura, the old software has to be removed but there is some cached data that usually must be manually removed.

CURA won’t connect to my Lulzbot TAZ PRO either.
