Raise3D HyperFFF: M99123 (lemmy.ml)

Comparing HyperFFF and "traditional" G-Code for Raise3D machines I noticed that the only difference seems to be the M99123 command at the beginning of the file (identical for different STL-models):

M99123 /RKIIyAfrgVn63QgWjcMv3w/DQafsD84EnC8915R6MD0Ipw/VGrHawCYdCJaNwKoDQafsD84EnC8915R6MD/RKIIyAfrgVn63QgWjcMv3w/DQafsD84EnC8915R6MD0Ipw/VGrHawCYdCJaNwKoDQafsD84EnC8915R6M/RKIIyAfrgVn63QgWjcMv3w/DQafsD84EnC8915R6MD0Ipw/VGrHawCYdCJaNwKoDQafsD84EnC8915R6M/RKIIyAfrgVn63QgWjcMv3w/DQafsD84EnC8915R6MD0Ipw/VGrHawCYdCJaNwKoDQafsD84EnC8915R6MD0Ipw/VGrHawCYdCJaNwKoDQafsD84EnC8915R6MD0Ipw/DQafsD84EnC8915R6MD0IpD0Ipw/VGrHawCYdCJaNwKoDQafsD84EnC8915R6MD0Ipw/DQafsD84EnC8915R6MD0IpD0Ipw/VGrHawCYdCJaNwKoDQafsD84EnC8915R6MD0Ipw/DQafsD84EnC8915R6MD0Ip0Ipw/VGrHawCYdCJaNwKoDQafsD84EnC8915R6MD0Ipw/DQafsD84EnC8915R6MD0Ipw

Any clue how this G-code command works and what is written there?

Yeah, didn't think it was an image, just images in gcode are encoded.

I did find their github with a klipper config, but yeah, unsurprisingly it's not there. You could see if it has documentation through the klipper console? I'm betting it's not going to be in your klipper config unfortunately. Definitely leaning toward it being the portion that has the firmware validate the key and then set things up.

I might have the klipper source unzipped from the update file (7 zip noticed that there is more data). Where do I need to check/look for this M99123 implementation?

The update file itself starts with: "RAISE - MXC - PACKAGE...." MXC might stand for STM MXcube as Rais uses an STM32 MCU. Scrolling through the file it looks like it also contains some sort of files for YOCTO-Linux for an NXP chip which might be related to the display.

Also does Klipper still use Python 2.7 and other EOL packages that are 15 years old by now?

Looking at the key-file: It is a gzip which contains a USTAR which contains some sort of, I suppose, key: "RAISE - MXC - KEY _ 'C[....]"

I was looking through, generally custom macros are in the config folder, unsure if they've implemented it differently, here's the Raise3D repo I found earlier, klipper has some code in c for the microcontroller stuff AFAIK with klippy in python, I've not personally dove into the code, just config and macro stuff largely.

Actually digging through a bit, there's some gcodes in /klippy/gcode.py in the above repo I don't see in the Mainline Klipper equivalent, like M9999, it might be a start, klippy lives on the host machine.

This is the base folder of the unzipped update.

Regarding the M9999:

	else if(strcmp((const char *)rec_cmd[ptr].cmd,"M9999") == 0 )
	{
		ansifo->main_cmd   = SET_AUTO_TEMP_CMD;
		return SET_AUTO_TEMP_CMD;
	}

For M99123 there is only one reference: https://github.com/Raise3D/Klipper-Raise3D-Pro3-Series/blob/97416850a18466eea04865f2c92503501841681c/klipper/klippy/extras/virtual_sdcard.py#L535
