I have been using a Taz lulzbot 6 for a few years off and on, I recently got back into it and was trying to print a large item but the right side of the bed is always off. The nozzle gets too far away and doesn’t push the filament into the plate enough for it to stick. (left side is measuring 0.61mm. and right side is measuring .84mm using calipers) Is there a way to level the actual bed itself? I already re-measured the frame and X-axis, all are aligned and equal.
I am using an Octograb flex bed and PLA filament
Nozzle: 205
Bed: 65
Did you check that the leveling spacers are snug?
I was surprised how loose the screws were on mine when I changed out to a new surface.
yes, the top right was slightly loose so I tightened it but it did not solve my problem unfortunately
If the left side is lower, that’s almost always due to some contamination on the nozzle that gets pushed away after hitting the first washer.
You can check for mechanical gantry-to-bed level by putting an object between the bed and gantry, turning off the steppers, and manually twisting the rods to make the left and right sides of the gantry equidistant to the bed. That’ll reduce the amount of auto-leveling compensation required, but at .2mm difference, that should easily be compensated for, regardless.
That’s what i was thinking, from my understanding any offset under 10mm should be auto leveled but maybe i am misunderstanding? I made sure the nozzle was clean before leveling the bed prior to the print so filament shouldn’t be throwing it off. Also, I am going to sound like a real newbie here but what is the gantry? I clearly still have a lot to learn. Thank you for your help!
The gantry is the x-axis, or assembly that holds the toolhead.
Any amount of plastic will throw it off. PLA is particularly sticky, and sometimes residue in the wipe pad gets stuck on, or some that was in the nozzle oozes down between the wipe and probe. I consider Lulzbot sticking to this measurement method to be about the worst decision they stuck with for so long. I understand that it makes swapping toolheads easier, but that’s generally something done relatively few times when compared to the number of prints you do that require a clean measurement… So they made a rarely used measurement easier to make the most common measurement less accurate.
Anyway, the nozzle needs to be SPOTLESS for it to work. ABS actually wipes off pretty well, but PLA is terribly sticky and if you plan to do PLA consistently, spend $15 on a BLTouch clone and customize Marlin to use it instead of the washers.
