Which of the three version is recommended for the SV08? Eddy, Eddy Coil or Eddy Duo. I will be moving to mainline Klipper. Also is there a maximum size Emmc, would 64Gb work or is the limit 32Gb?
Thank you
I dont know of any reason as to why a larger Emmc wouldnt work. Most times size limits are due to the file system used on flash drives. In klipperOS that is ext4.fs:
The ext4 filesystem can support volumes with sizes in theory up to 64 zebibyte (ZiB) and single files with sizes up to 16 tebibytes (TiB) with the standard 4 KiB block size, and volumes with sizes up to 1 yobibyte (YiB) with 64 KiB clusters, though a limitation in the extent format makes 1 exbibyte (EiB) the practical limit.[13] The maximum file, directory, and filesystem size limits grow at least proportionately with the filesystem block size up to the maximum 64 KiB block size available on ARM and PowerPC/Power ISA CPUs.

Thank you, that’s very helpful
I got the duo. I have it connected by USB. I thought that if at some point i want to go CANBUS then the Duo would be compatible. Price is about the same so…
Thank you that makes sense. appreciated

Attention! Eddy Coil does not have thermal compensation and is therefore not suitable for Z-homing. The sensor can only be used if a Z-homing device is already present.
Hi does this also apply to the Eddy Duo? Can the pressure pad on the back right of the bed be used for Z homing?
Thanks
The duo requires no separate homing device, does USB and CAN and does temperature compensation, I would think this as the best choice
If only USB is on your list then the v1.0 is the budget option with all the features except CAN
Also, mainline klipper is needed. An in-depth guide how to mount it and calibrate it is made by the printasaurus : https://youtu.be/xnGhGZesipI?feature=shared
I ordered the duo, and have got my kit together for the mainline upgrade. Going to wait for the Easter break so I can attack it with a clear mind and free time to get my head around it. I’ve come from a stock Ender 5, so no experience with Klipper but I did once flash the printer to add a CR touch and filament sensor. It was challenging but I am looking forward to not needing to recompile the code every time you make a minor change to the config. That totally sucked.
Thanks for your reply.
PS Printasaurus is Awesome, very clear walk through at the perfect level for me.
Be sure to carefully follow GitHub - Rappetor/Sovol-SV08-Mainline: Getting the Sovol SV08 onto mainline Klipper procedure from their description and not an older video or something. Documentation is constantly updated on this GIT.
I will try and move one of my sv08 printers to mainline klipper soon, I needed them to finish some print jobs first

Seconded. Personally, I hate youtube based tutorials for code related things - a good written description is far superior. I used Rappetor’s guide on my printer and had a successful migration to mainline.
And definitely go with the eddy duo - personally, I’m using the eddy-ng fork of the software (there’s a channel for it on the Sovol discord) that allows a combination of sensorless homing + a touchoff during the start sequence to nail the 0 point before bed meshing. Flawless first layers are basically a given once you go through the legwork of setting it up right.

Good to know (and i agree, video are tooo long), so what you did is that ? Home · vvuk/eddy-ng Wiki · GitHub
Are you using it in combination with GitHub - 3DPrintDemon/Demon_Klipper_Essentials_Unified: Devilishly Good Klipper Macros! ? (because i am using it and he has a configuration for eddy)
I’m a little confused now, is the eddy-ng fork move suited to the sv08 over mainline Klipper?
No! Ditching Sovol’s version of klipper was literally the first thing I did with my SV08 after printing the test Benchy off the USB drive. I have never had a good experience with companies that release their own custom versions and don’t keep them up to date with mainline.
The eddy-ng code only works on mainline klipper (and on kalico, but anyone who can’t even handle moving to mainline Klipper shouldn’t even think about kalico).
Nope. Mostly stuff from the sovol discord, and my own tweaked print start macro.
Thx. I will try with the simple eddy (the ng one require to replace the hotend cover, I will do that later). I just received it today.
I tried to go Mainline Klipper on my SV08 but as soon as I started the Z Offset calibration using the pressure pad the printer started to crash and do whatever wanted to, reverted back to Sovol’s version everything went back to normal immediately.
I followed the guide on github and the video mentioned above, non of it worked for me, SV08 specific features broke every time
