ImportError: cannot import name 'prtouch_v2_wrapper' from 'extras'

After getting the mcu code compiled and flashed onto the printer, I get the following error when running the klippy host on a Raspberry Pi 4

I noticed that https://github.com/CrealityOfficial/Ender-3_V3_KE_Klipper/blob/main/klippy/extras/prtouch_v2_wrapper.cpython-38-mipsel-linux-gnu.so appears to be built for MIPS architecture which might be problematic here.

Here's my host cpu info

Same problem here/ @CrealityTech can you please either share the source code so that we can compile this module, or distribute it for other architectures?

processor : 0 model name : ARMv8 Processor rev 4 (v8l) BogoMIPS : 48.00 Features : fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid CPU implementer : 0x41 CPU architecture: 8 CPU variant : 0x0 CPU part : 0xd03 CPU revision : 4

@CrealityTech can we have feedback on this please. Same for the CR10 SE and K1 range.

is there an update on this? I am trying to run a raspberry pi based klipper on my KE and I keep on getting this error too.

It's pretty much a waste of time posting here. Is seems to be just a facade for Creality so they can claim to be "open source".

To make it worse z_compensate.py is also compiled , since the latest April release!!

@CrealityTech @Taylor111593 are you going to respond to us? You can just as well take down this repo (and the other ones) as it pretty useless and creates a false sense of hope for us.
If you prefer to exclude the community from contributing to the code, there is no use for it.

PS: I completely abandoned the auto zoffset. I do it manually , when needed. I also did a DIY conversion to the Unicorn nozzle, because it does not look like Creality is ever going to release a version for the CR10SE. It is either because of how the load cell works, or the fact that there seems to be very little effort behind spares for this printer in general.
