Elegoo Neptune 4 & Mainsail, Klipper config

[ornate moth]

Hi there!

I have an Elegoo Neptune 4 (not pro/max) and I'm working on setting it up with MainsailOS on a raspberry pi. It seems they might use a non-stock (older?) version of klipper. I have setup Mainsail OS and am working on klipper configuration. I have the most recent printer.cfg for my printer, and found the most recent plr.cfg. plr.cfg references '/home/mks/klipper_config/' in search of 'saved_variables.cfg' (and potentially more, later).

I can see that mks does not exist. From what (very little) I understand, a newer version of klipper has migrated to printer_data, but it's not super clear to me what I need to do to resolve. Would someone be kind enough to help me out a little?

Thank you so much!! I really appreciate your help 🙂

(I don't have any logfiles, but I don't think there are any for this quite yet)

in your screenshot above is a "klipper log" download button

and also post a link where you downloaded your printer.cfg

[ornate moth]

oh god, oops

printer.cfg came out of elegoo's firmware here: https://www.elegoo.com/pages/download (neptune 4, firmware V1.1.3.1)

here's the log, sorry about that

to be honest, the complete file is not very useful. this will only work on a neptune sbc itself, because of other dependencies. at first i would exclude the plr.cfg file (this is only for power loss recovery). this is possible with just add a # in front of [include plr.cfg]. but there are also some gcode_shell commands in the config. this is also no generic klipper function and you have to mod your klipper directory for that.

personally, i would clean the entire config from elegoo's own stuff and only use the "default board config" and then install what you personally are missing. i also don't really like some of elegoo's macros as they are written... but that's just my personal opinion.

[ornate moth]

I am really new to 3D printing - I'm not sure what else I might be missing from a default board config

[arctic terrace]

oh ok. so you dont have deep knowledge in printer configs/usage?

[ornate moth]

not at all, sorry

I have working knowledge of SSH and things like that from when I formerly daily drove linux, but 3D printers are totally new to me

[arctic terrace]

ok. have you ever googled whether a "clean" printer.cfg exists from a community or similar for the neptune 4?

[ornate moth]

I haven't, but when searching for printer.cfg (before finding it in the firmware), I didn't see anything that looked similar to that. IT was actually quite hard to find the .cfg at all outside of the firmware. I will see if anyone in the elegoo discord has one (when I went there with this, the folks active encouraged me to try a wifi dongle instead of this whole approach but I'll be asking there again probably)

@ornate moth i cleaned the printer.cfg and this should now work with a "clean klipper installation". you maybe have to change the serial path to your board. i dont know if you flashed already your board with klipper.

[ornate moth]

Apparently if you flash the elegoo printers with a new version of klipper it completely bricks them

So... my main takeaway is that the printer I bought is one of the ones that simply does not play nicely with anything
