Taz 6 broken USB-B port

UPDATE V2:

I got it working! I leveled it again, and also double-checked that filament was being fed in. It seems like the issue was the lack of extruded filament in the probing process. Running pretty smoothly, just gotta tune it and learn!

I still need to solder my USB-B port back onto the board. Any advice here would be greatly appreciated!!


UPDATE V1:

I tried to do the leveling better. It worked! Finally did the benchmark……except I didn’t have the filament feed into the extruder smh. So after putting the filament in properly. I tried again. And now I’m in a probing failure loop. Is there a trick I need to perform that someone has figured out?

Going to keep testing stuff until I get my first print today. I am determined!


Original Message and Issues:

Hello! I was given a Lulzbot Taz 6 for my first printer the other day.

I am needing to update the firmware to hopefully resolve a probing failure that occurs at the bottom right post.

I unfortunately found out that you cannot update the firmware via the SD card. On getting a usb-a to usb-b cable, I found that the usb port was barely on there and came off. The dread.

Anyway! I am figuring I will need to learn how to solder, then solder it back on? Seeing as I will be learning how to solder, I wanted to get some advice or alternate troubleshooting steps to take to get the printer up and running in lieu of soldering immediately.

Steps I’ve taken:
Followed the probing failure guide which has me “Measure from the X-axis smooth rod to the Z upper connectors on the right and left side,” verify and auto home and then go to Z:270. And theeen do a print which is the rocktopus.

If it’s failing on the first probe point, it’s usually dirty nozzle or a break in the probe circuit on the bed or in the nozzle.

If it fails after going to the other side of the x axis, that’s usually a misaligned gantry. Get the nozzle close to the bed on one side, then power off the machine, and make sure the nozzle is the same distance between the left and right side of the bed by manually turning the threaded z-axis rods. If the left/right extents of the x axis are less than 2mm apart, the autoleveling shouldn’t have a problem.
