Guys,
I believe I have a bug in my Klipper. I use Palette2 and it works fine. But now it updated and it just stopped working. The settings are fine, but when I give the command “PALETTE_CONNECT” an internal error occurs and Klipper shuts down. Does anyone know how to help me?
Internal Error on command: “PALETTE_CONNECT” after this error klipper shuts down and it is necessary to use “Firmeware Restart”

@cmroche would you support?
Yeah will take a week or two though
thank you, I have no way out here, I came Using people who understand more
the palette2 module in klipper isnt updated to python3 right now. you can switch to python2 for klipper. i hope someone can update this module.
Any updates on a fix? I, too, would like to use my palette2 with Klipper.
Soon… sorry… busy time of year for me.
I’ve started to do updates this weekend though so I can test and try to reproduce the problem. Worst case scenario is that I will fix this over my holidays from Dec 19th onwards, but I’ll try to get something sooner 
Anybody found work around for this in meantime? Tried this solution below that supposedly revert back to python 2 but didnt seem to work:
Unfortunately I didn’t get anything here… I’m also waiting for someone with a solution
Sorry for the delay, setting up and starting to look at this today.
Thank you. I won’t be able to test any changes for a few weeks but will do so as soon as I can.
Yay, I’m looking forward to using the palette again.

will this correction be incorporated into Klipper? Because being honest, I don’t understand much about programming to change around here 
Kevin merged it into main 2 days ago. It’ll either be in the next release, or you can use the dev channel to get the latest.
I have klipper, moonraker, etc all up to date but still cant get this working. Palette 2 is definitely connected to Pi, I have this port set for it in printer.cfg: “/dev/serial/by-id/usb-FTDI_FT230X_Basic_UART_DM02FQQJ-if00-port0”
When i start a print that should use it it says “Cannot initialize print, palette 2 is not connected”
Here are versions i am on for kipper and moonraker.
klipper
v0.11.0-87-g0407c24c
moonraker
v0.7.1-821-g12b1bef
Im in the same boat. Everything is up to date, and the pi verified that it can see the Palette 2 via command line.
I will say, I am using MainsailOS. Anyone else have that same setup and still having these issues?
unfortunately I haven’t been able to since I opened the topic… a pity because I use the palette a lot and now it’s stopped
Any update is this is working? Going to try again soon but if it’s not working still not going to bother.
