Do you know if this, Z offset in the Beta works?
I will try it in 0.02 increments until the visible layer lines disappear.
After posting the original question I remembered I was getting perfect layers with the original 0.4mm nozzle, I have been getting the issue with the 0.6mm and 0.2 mm nozzles, I am away from home at the moment but as soon as I return I will change the nozzle back to 0.4mm and try the offset if it is still showing layer lines.
Hi i wrote a thread regarding my .2mm nozzle jamming. I believe it’s a problem with the offset. Can someone please recommend the right value here for .2mm nozzle with a smooth plate?
I also ended up on this thread because my 0.2mm nozzle was too close to the build plate and clogging. I used the code from this thread to raise it 0.03 mm on the smooth plate, and also adjusted my slicer settings so the first layer is thicker (0.14mm), which has helped dramatically.
you need to do this
(1) Make sure you add the a new printer with the right .2mm nozzle settings in the slicer.
(2) Once you change the .2mm on the menu on the actual bambu printer. Ensure to REBOOT THE PRINTER and then run calibration again.
Is there some bug there where the calibration doesn’t work properly after changing the nozzle in the settings without rebooting?
Yes i believe there is a bug. Also i’ve found that the z alignment seems to be losing accuracy after a number of prints on the latest firmware and require a reboot to fix it. I never had this problem with previous firmware so yes i think it’s a problem with Version 01.04.00.00
does anybody noticed this strange behave by using orca slicers z-offset?
Does anyone know how I can define a Z offset that also works for manual Flow Dynamics Calibration?
Same here. It seems to only affect the preview. Not the actual print. Its a bug for sure.
when you mess with the z-offset, you’re messing with layer adhesion. It’s not what you think it is.
If you think your nozzle is squishing your filament, you’re over extruding.
If you’re having print issues, its not z-offset. print a temp tower, run a manual flow calibration, spray some aquanet on the plate.
every single filament will need to be calibrated. If you decide to change the z offset anyway, you can edit the start g-code, at the bottom of that startup code, near the bottom is the z-offset. Save that as a different named profile, for example, nozzle size, z -0.01
Hey, very nice code
It work, but check because in the “High Temp Plate”
the front and but " " it’s different and throws an error
z-offset only affects the first layer and has nothing to do with layer adhesion nor somehow cause bad layer adhesion . Spreading false information is bound to mislead people.
Z-offset is used for first layer squish and that’s it. Could someone be overextruding instead of being too close to the bed? Sure, but that can be determined through flowrate calibration.
z-offset is necessary for many filaments that either expand when extruded (silk) or flow easily (petg), where flow calibration would affect ALL parts of a print and cause under/over extrusion at other areas (like the top surfaces).
What a wonderful story. And you tell it so well.
Anyway, the offset is for every layer, and effects the squish of every layer on to the last. Ie layer adhesion.
If you print a z-offset test print, that’s literally what you’re looking at. Not just first layer.
That would be dumb lol
No, you are mistaken and clearly can’t be bothered to look it up yourself. When you set a z-offset, what happens? It moves the bed closer or further away from the nozzle. Now, when that happens, what happens to the first layer? It gets more or less squished while still extruding the same amount of filament, all things being equal.
Now, what happens to the next layers? That’s right, they are now ALL OFFSET BY THE EXACT SAME AMOUNT. Thus, there is literally 0 change in their adhesion to one another or any other factor. You aren’t all of a sudden shortening the layer height of each layer or squishing them together more by the set z-offset, because every single layer is offset by the same amount.
Thus, the only layer that is affected in any way by z-offset changes is the FIRST LAYER. Hence the term Z-OFFSET.
The only thing Z-offset affects is the distance between the nozzle and the bed, nothing else. It is held constant throughout the print unless you are using a live-z.
you’re actually right.
I was thinking something completely different.
I got the alert in the mail today so thought it was a recent conversation. I was wrong anyway.
Thanks for taking the time to clarify.
