Taz 6 Z Probe: I need some bed leveling help

I have replaced my tool head with a new HS 0.8, after using the HS+ for a couple of prints and am noticing that the HS head can’t print PLA. Basically, if I can get the Z Probe to not fail, the print pulls off the bed. I decided that it might be a bed leveling issue, so I ran the M29 command to test…

Here is the output:

Does this look bad? I assume that these output numbers should be close to zero as possible. I have not modified the bed. Does anyone have any suggestions as to where I might start to look for answers?


I think your X axis might need to be leveled as the left side is .8+ and the right side is .0+. Take a look at https://forum.lulzbot.com/t/taz-6-probing-problem/6841/1 for a quick check and leveling procedure. Also, take a look at https://forum.lulzbot.com/t/solved-taz-6-auto-leveling-is-0-5mm-off-now-perfect-to-0-01mm/6250/1 which discusses even finer tuning of the bed.
