Prusa mini Fysetc clone - log of a journey  

RE:

That's what I was going to ask you... I'm using the 5.1.2 corrected by @turro75 to avoid flickering of the original firmware

RE:

I have not had to worry about flickering since they instituted the new versions with input shaping.

Try to downgrade the firmware. My orig. Prusa Mini is running with fw 4.2.1 (tried div. hotends: Revo ok, MK3 E3D ok).

I can't say whether your problem is caused by the firmware, but a test with an older version may provide new insights.

wbr,

I have downloaded to firmware 4.4.1 and it gives me the same error...

With cable unplugging from board 12208 and with the cable plugged into board 12206.

I've finally solved it... I think it was something badly connected. I disassembled everything, I started from scratch and the magic happened.... it worked.

I have no other explanation.

Thank you so much, @Karl-herbert and @cwbullet for the help!!

Hi All,

I updated the patch file to the latest 6.1.2 to enable also the skew correction.

For those who want to build it on his own this is the sequence (I'm on MAC M2):

First of all ensure You are using python3.11 or the build process will fail, on Mac I use the following commands in a terminal:

brew install [email protected]

git clone  https://github.com/prusa3d/Prusa-Firmware-Buddy.git 
cd Prusa-Firmware-Buddy
git checkout ffed3df   #this forces version 6.1.2

Now copy the file Fysetc_6.patch to the dir Prusa-Firmware-Buddy

patch -p1 < ./Fysetc_6.patch
python3.11 -m venv .venv
python3.11 utils/build.py --preset mini,mini-en-es,mini-en-cs,mini-en-de,mini-en-es,mini-en-fr,mini-en-it,mini-en-pl,mini-en-jp --build-type release

 You can skip the preset not required by deleting them from the last command.

During the update it erases all the settings so at least take note of the Zoffset value.

  After update during the self calibration test the display got completely messed, neither rebooting fixed it. I switched off, unplugged/replugged the dispaly flat on display side then it reboots and it did not happen anymore....mah....who knows....

I have to say that the printer is now completely free of noise. Just for that I recommend the update.

Recently, the Wi-Fi on my printer has stopped working. I don’t know if something was changed in Prusa Connect and now it no longer works on Fysect versions, or if it’s just mine
