@fractalengineer
Can you post your full motor related config.
My motors are extremly noisy on my MGN Cube.
I DIsassembled everything the last 2 days, and reassembled the full frame, and it is still 100% the same.
When i switch beteen spreadcycle and stealthchop, i can not hear any difference, and i dont know why...
@dc42
I will.
But i can only do it wednessday earlierst, as I am out with my family the next days!
I can confirm also a kind of this bug.
Before the update I had around 29°C on the HotEnd.
M308 S1 P"121.temp0" Y"thermistor" A"HotEnd" T100000 B4725 C7.06e-8
Any timeframe, when I will be able to use the Accelerometer in combination with a SBC in a (Beta)Firmware?
Thanks
@dc42
Sorry, it took some time on my side.
I upgraded to the beta2 (with SBC) but faced some issues.
Mesh bed leveling (BLTOUCH) was not working properly because the PIN was not always pushed outside, but it tried to probe.
But than I had some hugh blobs randomly,... on edges/directional changes of the print.
Tried to read out the values, which was working, but were not really able to make some "benchmarking".
I went back now to the 3.1.1 and all "problems" are gone with the BLTouch and blobs.
I think also this is matching with some other posts here, at least for the blob topic
Changed now the motors to a TRINAMIC (QMot) QSH4218-47-040 with "ultra low impandance" of 0,6mH.
Result is day and night with spreadcycle. It is just sligthly louder than a my other steppers with dampers, but without dampers.
When i switch on stealthchop, it changes significatly the aperance of the noise to a differen sound. So it is switched on at least. But as i went back to 3.1.1 i can not read out the values.
I will try now more different values, but i am missing a little bit the understanding how it is the H and V value correlating.
Pure Stealchop mode: it runs well with around 100m/s
In Hybrid mode, i get some strange sound and stuttering, even if i config the "switch" speed to 80mm/s.
But properly the H + C + T values are not combined well.
Can you give us any indication when the Beta3 Version will be available?
Hello,
thank you for the feedback.
Ok, so i will upgrade the System to the Beta and let you know the result after I tried this!
@Phaedrux
Thanks a reply.
How could I interpretate this reply?
There will be some more input/software modification/bugfix (If there is a big)/whatever from your side, but you need some more time?
Perfectly fine for me, but I (we) should know that something is ongoing.
Right now I don't know if I have the wrong setup(steppers, PSU,...), if I configured something wrong or if you can do here anything on the software side.
I am looking at the moment to test a SKR1.4 with RRF for LPC and TMC2209s, to see if this gives better results. (I have all hardware here)
If there will come some solution from your side, I will wait and not invest this hours of testing/setup...
Absolutly no feedback on that topic?
Is this topic closed for posting, hidden or something, or does really nobody has any input (@dc42 )
I would appreciate at least a: no solution or a "bug" reply, that I know what is fact.
@dc42 Any news on this point?
"btw in the imminent RRF 3.2beta you will be able to read out the values of the PWM_SCALE and PWM_AUTO registers, to see the result of stealthChop tuning."
@dc42
XY-Core Setup.
So, i tried now the following:
--------------------------------1-----------------------------------
Both way do not seems to change something on the sound level. (the printer is not extremly loud as before, because i use now dampers, but nevertheless, even with dampers I should hear a difference between spreadycycle and stealchop???)
Any other way suggested??
