Okay i got my Tap working and everything configured but i have issues trying to figure out what is causing the walls appearance to be so inconsistent. Anyone have any ideas? PA is tuned at 0.025 Resonance test was saved to the printer.cfg file print speed is 200 inside wall, 150 outside wall inland PLA print setting: nozzle temp 200c, bed temp at 60c? what am i missing? i do not see any ghosting but these walls only look bad when looking at them with the light shining down the layers.. Any help would be great thanks!

Any luck with this? I'm getting the same type of issue on my V2.4

so im working back on it and this is my height map, and i think i know the problem but cant figure out how to correct it.

#

the front of the bed is good but the 1 layer print starts in the front right and looks good. as it sweeps back and forth for a whole bed 1 layer test the front looks like the squish is good about 3 inches into it the nozzle begins to lift slightly and the squish becomes non exsistant and the extruded lines dont connect. I did a heat soak hot nozzle QGL and then ran a bedmesh it got to 0.002 tolerance is 0.005. and the first layer still looks like crap.

#

dont mind the bigger spaces i removed it and then put it back on the printer because it shows up better on the issue

#

Anyways i think the iussue is that the gantry is to high on the back of the printer. and i cant find anyway to adjust it. when i manually try to move the Z motors up on the rear motors the gantry pulls back into the same position. do i need to loosen the Z pivoits to make an adjustment?

That first height map looks like you didn't do QGL before bed meshing. The second one though looks like it is done more properly, and pretty normal (a range of 0.2mm or so is about what one can expect).

i just unscrewed the pivoits and ran a QGL and then moved the Z up to retighten the gantry pivoits and im test printing a new single layer now

Not sure what you're trying to "adjust". Do QGL before the bed mesh, the bed mesh then looks fine, and the resulting error seems well within what it should happily deal with. Whatever the first layer issues may be, I don't think "the gantry needs adjustment" is among them.

#

Also make sure the bed mesh is actually applied and running. You'll see this in mainsail by the Z value moving around a bit as the toolhead moves over the bed.

also to add my bedmesh runs at PrintSTART i also made it a 8,8 grid

#

Can you please post a klippy.log? Not entirely clear what you mean by "runs at print_start", and the ones you're showing are decidedly not 8x8 grids.

@velvet tangle im not sure what a klippy.log is, as for the 8x8 grid for the probe points i started at 5x5 and moved it up to 8x8. im starting to think i ahve something configured wrong because it should also be running a adative mesh but when the print starts the printer probes the entire bed surface not jst the print area.
