Klipper 13 vs 12

[GreatSunJester]

Installed ZMOD on one of my two AD5X and so far it is fine. I have not yet dove into plugins!

I see that in the FAQ it says:
ZMOD uses the standard Klipper from the native firmware, as well as Klipper 13

But after my install everything says Klipper 12:

13:00:38 // Installed from USB: 1.6.2. Update from Fluidd/Mainsail: 1.6.2
18:47:43 info You are using native screen
18:47:43 // Using native Klipper 12

Have I missed something ?

Yeah, same here, from today on an AD5X

16:34:17  info You are using native screen
16:34:17  // Using native Klipper 12
16:34:17  // zssh:
16:34:17  // Installed from USB: 1.6.2. Update from Fluidd/Mainsail: 1.6.2
16:34:17  // Zmod version: 1.6.2 Date:   Mon Oct 27 15:40:41 2025 +0500

Also noticed that when I went to the web interface I had to add a printer, ended up doing http://{my-ip}:7125 , and then the fluidd webapp comes up, but there is no update in the settings (after Gcode preview), and in the general tab there's a warning "Klippy not connected"

To enable Klipper 13, you need to run https://github.com/ghzserg/zmod/wiki/System_en#update_mcu
But keep in mind that Clipper 13 on the AD5X is less stable than Clipper 12.

Got around to working on the 13 Klipper 5x.
Testers needed.
We require the following:

1. Update the mod to the latest version (not below 1.6.2.375-6)
2. Update the MCU to version not below v0.13.0-375
   UPDATE_MCU FORCE=13
3. Print a file that doesn't print on the 13 Klipper but prints on the 12 Klipper.
   Tag me and attach the problematic file. Or send the file via private message.

How long should the switch to klipper 13 take? I've been stuck on the "Upgrading MCU, please wait..." screen for over an hour. Should I keep waiting?

[not-crazyramen]

if anyone else experiences this, I just power cycled it after waiting a bit and it's back on and fine.

Does the native screen works (with flashforge ui) with klipper 13? Or is needed to switch to helixx\guppy?

Works

I've been using klipper 13 since 1.6 and never had issues so far.
