looking for some help or advice, i recently switched over to using just spread cycle on my tmc 2209 drivers and when doing resonance testing etc i get really high numbers and recommended values… and both x and y are exactly the same at 148.8 hz with accel at 86300 mm. i have a tremendous amount of ghosting going on and i only have my settings at ma accel 600, max velocity 500.
so i guess im asking did i mess something up in my config? belt temsion is pretty bang on not to tight and not sloppy loose. any help would be great.
please note i had to zip my log and config due to it being over 8mb.
Yeah with my adxl readings i simple ran the resonance test through my klipper screen menu on input shaping, then it just automatically sets it in my printer.cfg as far as i have seen. The link you have in your reply i have read through those articles and for some reason i just cant get my head working to achieve the out come explained, like do i do this throught ssh or my command line on mainsail etc. I would love to see the graphs to better understand whats going on etc. Some things with klipper i have found easy to understand and get done, others i dont know if its just due to not enough info for my brain to compute or if its just past my technical skills lol.
Is there a write up somewhere thats more like a for dummies guide haha? I would really like to be able to just upload the required info as of late ive been able to understand how all this info shows exactly whats going on, and now know when i ask for help it makes things so much more simple.
The instruction is quite easy to follow, you just need to know what you have and when to use it.
You mainly need Mainsail/Fluidd and a SSH connection to your RasPi CM4 or CB1 compute module.
Lets call the first GUI and the last SBC (single board computer).
The guide on the link above often says OctoPrint, however we use Mainsail/Fluidd here. And there the console. @Sineos when has Octoprint been put in the guide? It looks reworked but if I recall correctly the OctoPrint stuff is relatively new?!
All the commands in capitals are run in the console.
And only where it says
These files can be processed with the stand-alone script on a Raspberry Pi
you run commands via console on the SBC connected via SSH (best is you use putty for that tasks).
And those commands run on the SBC are only the following:
thanks brian i will try this, i probably simply over thought on the process, i do use putty and i run a cb1 on the manta board so lets hope i do this right lol
so quick first off running the query command i got this back which has me puzzled as it is a core xy machine.
accelerometer values (x, y, z): -2886.803174, 0.000000, 2911.162892
ok so i have followed all instructions everything is upto date and installed…when i run commands given by brian i get all the tests and recommended shaper etc, but i do not get a graph so obviously i have missed something?
ok so it appears it is an access issue for me in ssh with my cb1 on the manta m4p… sadly i only know of the main password user name from the intial setup then what it was changed to once the install was complete.
so i dont know how or where to find out how to enable root access for me on the cb1.
Do you really use Ubuntu and Putty as your daily “work machine”? If so, this should be easy for you: As you can see from the two directory listings, you have a /tmp folder right where it used to be, and in your temp folder you already have the resonance measurement files:

calibration_data_* comes from automatic calibration via SHAPER_CALIBRATE
resonances_* comes from the TEST_RESONANCES commands as detailed in the posts above
shaper_calibrate_*.png are your graph files from the ~/klipper/scripts/calibrate_shaper.py
Again, under the assumption that you use Ubuntu as your main work machine to access the CB1:
Open your favorite file browser, e.g. Nautilus, Nemo, Thunar, etc.
Enter sftp://biqu@YOUR-CB1-IP-ADDRESS in its address bar (if you enter “YOUR-CB1-IP-ADDRESS” literally, I will find and beat you )
well unbuntu is rather new for me but caught on with it quick…but as per your advice yes i agree it is right where it should be. i am starting to believe it is an issue that lies within the laptop i use for the printer work. i tried running the sftp prior to tonight and i get nothing, and this is why with your suggestions here I think it is conclusive…
my laptp running ubuntu is on holidays?
I got a second defective manta board/cb1, first one died after running one print.
so i guess i have to debate how i wanna move forward.
