Hi, since a few months i have issues with the auto-leveling or leveling in generell. I think it is a problem with the leveling because of the quality of the first layer, and the fact that the printer (A350) has also driven it self into the printingbed after an auto-leveling cicle.
I have allready updated the firmware and tried other things to solve the problem. This includes heating up the printingbed before leveling, leveling by hand, auto-leveling, pushing the Z-axis to its top position aswell as changing the grid density of the leveling grid.
Oh and i sould probably mention, that sometimes the nozzle is to high and sometimes it is to low. But most of the time it is to low.
besides the obvious problem with the leveling the printer sometimes has problems with transfering the data from the usb-stick to the touchpad and sometimes even crashes. So just for you to know, i also have that problem. But I am not sure if those problems have anything to do with eachother.
Thanks already for all answers and i hope my discription was understandable.
I have the same issue because the bed of the Snapmaker is in general not good and i asked a company to make me a custom printbed and its a lot bette than the original but as you say sometimes I have the feeling the auto leveling is doing nothing I run a 11x11 grid and print then a bed level test and its just trash as if the printhead does not know the mesh or the high and low points of the bed @Melitta_Snapmaker@Edwin!
wich slicer do you use? maybe the error is in the settings? do you use the calibration card for the last point or a feeler gauge?
I am just using luban but from what i have already read in this forum, i should probably change to something else. And yes i use the calibration card because i donāt have a feeler gauge yet.
yeah you are very limited with changing settings in Luban. but when u using Luban this should not affect the first layer. what does the layer looks like? is the line with correct how old is your nozzle or the filament that you use? is the surface of the layer ruff or something like this?
Hereās some instructions I received from support once. Frankly, you might have to wait until the latest development firmware is released as thereās a bug in the calibration that could explain your issues.
In the meantime, just use the center 100mm of printable space and nothing more, it will limit the un-levelness.
ok no wonder I have such problems with the first layer too bc I already calibrated the most things except for Acceleration Tuning and always running a 11x11 grid for leveling. hope they will release it soon!
and even did a mesh of my bed via octoprint and it doesnāt look that bad.
An option is to use Toneās tweak macro script to adjust each mesh point individually to compensate for the measurement error. Itās based around issuing M421 Q commands (Set Mesh Value | Marlin Firmware) to adjust each point a bit.
He mentions heās having auto leveling problems. If the auto leveling is too low (which he mentioned) , the nozzle pushes the bed down during auto level, causing horrific auto level offsets. I agree that it wonāt fix tons if leveling by hand is also way off, I suppose.
Thanks you i will try the tones macro skript aswell as the adjusting of the sensor maybe it will help!
Also heres a pic of my bed level test print if you want to see
@NilartPax I thaught about moving the sensor, but decided it could make things worse as @WilliamBosacker stated aswell. So no, i did not adjust the Sensor. And After the things we discussed i wont touch the sensor.
Update:
I took of the whole printingbed and then reatached it again. After that i carefully leveled the whole thing and then printet a test, which was way batter than the previous test prints. But still you are able to see where the nozzle went to deep and where it went a bit to high. But i think that i will be able to get rid of those imperfections after i perform a 11 x 11 leveling. And then i think the fix in the Firmware will do the rest.
Obviously it would be nice to know for when it is planed to be released, but i donāt have any information on that. I donāt know if you have any insights regarding this. Because i certainly donāt. And i am apologising if Snapmaker released anything and i missed it.
Can you share some photos of your machine?
A lot of peoples problems are caused by improper assembly.
Take some pictures from the front at bed height, at z-tower height in front looking down, etc.
I am sorry but i wont be able to post some pictures until about two weeks from now. Someone else is going to have to do that, or you have to be patient! Iām Sorry.
Hi @Maximos Use a USB cable to connect the machine to a computer. In Luban, input M140 S70 to heat up the heated bed first and then do the auto-calibration or manual calibration. After that, please have a check whether it is better.
Some customers adjust the screws between the platform and heated bed and it may be helpful.
Our engineers are still working hard on this issue.
Thanks for your patience.
Some are lose and others have marks of the nozzel pushing the filament to the sides. And some have both.
