Klipper 0.13 update

[ChicagoKeri]

This seems like a good place to comment on the new Klipper 0.13 update!  https://www.klipper3d.org/Releases.html

Klipper 0.13 has some neat new features... but will it crash various MCUs like the Klipper 0.11 > 0.12 did?  For me, No, it does not.

 

Victim #1 - Voron 0.2 with RPi4, BTT Pico on USB and BTT EBB36 on CAN via U2C: 

Went from an earlier version of Klipper 0.12 to 0.13.0.51 with no issues and remained operable with the Pico and the EBB36 still running 0.12 firmware.   The Katapult-equipped EBB36 successfully flashed to 0.13 after doing a make  menuconfig and reflash.  The Pico reflashed by USB without issue. 

 

Victim #2 - Voron 2.4 with RPi4, BTT Octopus1.1 on USB and a Mellow SB2040 on CAN via U2C:

Went from the latest version of Klipper 0.12 to 0.13.0.51 with no issues and remained operable with the SB2040 and the Octopus still running 0.12 firmware.  The Katapult-equipped SB2040 successfully flashed to 0.13 after doing a make menuconfig and reflash.  The Octopus reflashed by SD card without issue.

 

So, it seems that the latest Klipper 0.13 is a relatively "safe"-ish major upgrade from 0.12.  MCUs must still be manually configured and reflashed which is probably a good idea or even necessary as make menuconfig appears to have a new option enabled by default, "Optimize stepper code for 'step on both edges' "... I left this enabled , does anyone know what this is for?

By the way, SHAPER_CALIBRATE does a whole new sweeping function... the toolhead now sweeps back and forth maybe 50mm while the vibration frequencies increase as before... on the V2.4 the results were slightly different with X going from MZV@57hz to [email protected]  and Y going from [email protected] to [email protected]...

I had some maintenance to do with my Voron 2.4R2 and had some time to update extruder to Galileo 2. 
Maintanance is done so desided to update  klipper to v0.13.0-51 from v12 using mainsail os.  
I didn't flash octopus pro board. Octopus stm32f429 is running v0.11.0-205.
Everything seems to work  without problem. When i updated from  klipper V.11 to V.12 i had a lot of issues but now everything is working fine.

Look at the "Machine" settings, where you will also find printer.cfg and information about the hardware.  

On Mainsail it is usually on the left side of the screen. you might have to expand the menu by clicking the symbol to the left of the "Mainsail" at the upper left corner.  Fluuid, I don't know.

On Fluidd it's System settings. The tower case icon near the bottom just above the gear on the left side menu. Then all the MCU information is on the right side panels.

Mainsail illustration: In my case the panel is on the right hand side under the System Loads panel.

Ok thankyou mcu is running v0.12.0-276

And sb2209 is v0.12.0-278

System has had full updates might have to look at how to do the updates on them 2 later I have kahaun installed if that helps

Plenty of guides on here for flashing via Katapult that are pretty comprehensive otherwise head to the source for canbus flashing Toolhead Flashing | Esoterical’s CANBus Guide or the documentation from the vendor.

Thankyou for the link

Hi. Advice needed. It looks like its time to update Octopus pro 1.01  F429 mcu. 
I run the make command and noticed that there is a new option enabled on the klipper firmware config list. 
The option optimize stepper code  for step on both edges is enabled by default. 
Last time when i updated the mcu this option was not enabled. 
So do i leave it enabled and comply firmware or do i disable it? Voron 2.4R2 running with LDO hi temp stepper motors kit.
Klipper version latest.

It looks like the basis has been in the mcu firmware for quite a while:

Trinamic stepper motor driver “step on both edges” optimization - General Discussion - Klipper

You may already be using it.

Hello. Just updated Octopus 429 mcu using sd card . Everything works just fine. Left option optimize stepper code  for step on both edges enabled.
This time updating Klipper and mcu went smoothly
