klippy.log oddly i cannot get it to let me download it? ender 3 printer.cfg.zip (3.1 KB)
ok this is a long one,
so since playing around with getting kamp to work then finding out there is a native attachment with the new klipper 12.0… i have had nothing but issues with this printer, weather it be by my own doing or some crappy bad luck.
so i cant get a decent level bed, cannot get a good bed adhesion on the first layer and thats even after doing a fresh bed tramming, new z offset etc, also i have replaced thermistor, the heat bed, new build plate, new heat cartridge, ned nozzel. now the filament i have tried new out of the package, dried in a dryer for 3 days with deccidant in with it and still no adhesion, but any of these said rolls go on the other machines they print like a charm.
so having said all this, im not expecting somone to know the answer, but maybe an idea i have not thought of, something i overlooked or missed?
could a fresh install be needed? i did notice i cannot download klippy log or completely delete kamp cfg files?
You are not alone. The best advice I can give you is to start over with a brand new sd imaged with RPI Imager. I am on v.12-0-179 and don’t forget to make sure both are on the same version. Start with a 0 offset then probe_calibrate after. Test small centered print. Remove ###do not adjust### at the bottom and add to bl touch offsets adjust by .010 until good. I have attached my printer.cfg and seems to work well but still adjusting. Also I was using a glass bed and switched to garolite g10 with Amazonbasic PETG. Use paper method with bed screws not tilt adjust. kiauh will help with everything.
Have you tried just using the standard bed mesh without the adaptive bed mesh and see how that prints? Adaptive bed mesh by it’s nature only measures the small area around the print.
It’s kind of like the curvature of the Earth. If you go outside and look, everything looks flat because locally it is. It’s only when you zoom out that you realize it’s curved.
Same effect can happen with adaptive bed meshing, it can be “locally” flat but your overall bed can be tilted/skewed/warped and it will affect the print.
I’d suggest stripping away all the fancy bells and whistles and start with a minimalist simple setup, get that to work right and then SLOWLY add things back in.
It is also important to consider that adaptive bed meshing is best used on machines that can normally probe the entire bed and achieve a maximum variance less than or equal to 1 layer height.
Also take the opportunity to learn how and why the machine works and does what it does. You may have mechanical issues (potentially numerous ones) that you’re trying to address with software. It might be possible to compensate for some of them but it would be better to make sure the machine is mechanically sound and properly constructed and then install and configure the software.
I appreciate your comments, to start out with this machine is the only one of the 6 machines running klipper, the other 4 are Bambi. Labs xc1 printers… so for the other three machines they run on a good day roughly .06 for a bed variance and on a bad day will throw around .08 .09 variance… as for this machine prior to this whole fiasco with getting kamp running on it it usually was around that .09-.1 variance then after this kamp it’s all over the board, but after commenting out the kamp (still can’t figure out why I can’t fully remove it?) it will run prints no problem with the variance back down in .1 or below variance.
So at this point I am lead to believe it lays within a programming or software glitch on this particular machine as the others are running kamp fine.
Why I have come to this conclusion is partly due to not being able to completely remove kamp files, also the fact that after a couple power cycles after commenting out the kamp is when printing and bed leveling went back to normal.
So my next option I’m guessing would be to reflash the board, and fresh install Klipper back on to host etc and then try again? Then if same results come about I would assume the board may be faulty even if it is a new replacement.
Given you don’t know my back ground I’ll give you a free pass on that comment…
As for machines this particular machine is the 7th one I have built and currently running klipper, the other four are Bambu labs xc1…… given the other 6 run without a hitch I do believe I have a good understanding of them, the programming with klipper maybe my knowledge is lacking, with saying that the only way to learn it is by asking, making mistakes fixing it etc. now I did notice on the one link you gave there were a couple others request that more information be put in, and that was back in February, but that besides the point, more so of a reply to your “read it again” reply.
In more then a decade of building and operating CNC machines this is the first machine to frustrate me to this point, but small little points etc from others have got me to the conclusion now that it is either a programming/software glitch that is remote to my machine(you can read my reply above to see some of that info), or it is a board issue which wouldn’t surprise me it would be the third for this machine, and that brings me to the final one that this machine is just plain cursed!!!
So your guess is as good as mine right now what will be the route on this one, maybe the trash lol we will see once it has been reflashed and freshly installed onto the host.
