Hi!
I’m getting this weird issue with a secondhand TAZ pro 6, the video is linked below. Essentially the nozzle is missing the right washers (around 4:00 in the video) and the print is aborted immediately after the back right washer is missed and the video ends. The nozzle is clean and the x-gantry is level with the bed. Any advice is appreciated. Thank you!
(edit: also the felt wipers are missing, but that’s an issue for another day)
Well, there is no such thing as a Taz Pro 6.
It’s just a Taz Pro.
What firmware are you running? I’ve been running modified Pros for a while now so haven’t seen if they’ve changed pre-leveling wipe sequence for a bit, but that motion at the beginning was never done before attempting to probe in the versions I was running.
There may be a nozzle offset configured, or your Y axis may have shifted at some point.
Without the nozzle wipers, you’re going to have a terrible time trying to get the nozzle-to-washer leveling to work at all.
I’m not sure what firmware it is running but I will get back to you once I find out. I assume it’ll be available somewhere in the menu. I will look into resetting the nozzle offset and y axes, and also into things I can use as wipers 
. Strangely though, the nozzle seems to hit the left front washer just fine.
Thank you so much!
It’s hitting the washer, but it’s not hitting it fine.
Leveling should hit the quadrant of the circle that overlaps with the print bed. It’s hitting the left side of the first washer. I can’t tell if it’s the front or back half, but it should be the back half. If it’s hitting the left side of the left washer, then it’ll miss the left side of the right washer.
Are you starting a print in this video, or did you just hit the “clean nozzle” option in the menu?
Oh, I had no idea – thanks for letting me know.
I tried to start a print in that video.
If that’s a start from a print, there could be a lot of bad startup GCODE occurring, and that’s usually more common than the Y axis being in the wrong place.
What slicer/version? If it’s not Cura Lulzbot Edition, posting the startup GCODE you’re using might also help.
It’s the octopus GCODE provided by the Lulzbot software (which I can post in a bit), and it is Cura Lulzbot edition.
The info screen for the printer says the firmware for the tool head is Pro Dual with FAME 3D and at the bottom it says “Marlin 2.0.0.144.5”
What version of Cura LE?
The version is 3.6.37. It seems like I cannot upload attachments since I am a new user, but here is the first chunk of the gcode:

Also, it seems like the washer issue was fixed by letting the machine recalibrate itself by using “measure automatically” for the nozzle offset. There are a couple different issues going on though, so I may start a new thread.
