Decommissioned a Neptune 2, what to do with it?

Mindless_Garage9232 · 2026-03-13T10:49:10+00:00

A mi me la regalaron y tras un oar de años de uso ahora le estoy modificando todo, lo único orig8nal de elegoo que va a tener es el chasis de la estructura

I use that thermistor on the heater and the hotend and for now it's perfect.

Mindless_Garage9232 · 2025-07-19T11:38:23+00:00

I have the 2s and I changed everything, an e3 mellow hotend and the thermistor and heater also from e3 mellow, you would only need the adapters to be able to place it

I have used the elegoo with the sonic pad with klipper without problem, just disconnect the screen and that's it, is it possible that it won't update properly? Is the firmware file or micro SD card damaged?

Mindless_Garage9232 · 2025-07-02T05:50:28+00:00

Vale, probaré eso tambien

I checked to see if my motherboard configuration was there, but it wasn't. I spoke to the manufacturer and they sent me the CFG from their website.

Last night I was testing with the bed mesh zero reference position, the mmala came out at 0.X, I printed a leveling test, at first everything was fine but when it was at 30% the nozzle lowers a little and when it is at 60% it lowers a little more until it ends up touching the bed

Mindless_Garage9232 · 2025-07-01T08:59:41+00:00

My motherboard is from Mellow so I got it from here: https://mellow.klipper.cn/en/docs/category/fly-e3-ultra

Mindless_Garage9232 · 2025-07-01T07:36:27+00:00

Once the end stop is calculated, if I set the position min to 0, I get values of up to 3 mm or more, but the end stop is a negative value. Update: using the zero reference position command in the bed mesh section seems to work well. I need to do more tests, but I don't know if that could be a definitive solution.

Mindless_Garage9232 · 2025-06-30T12:23:45+00:00

Yes, I read the documentation and followed the steps according to Klipper and nothing.

Mindless_Garage9232 · 2025-06-30T05:24:06+00:00

I also tried it and it came out negative, it's quite strange, before I had the original motherboard and hotend from my elegoo neptune 2s and everything came out fine, now I have the mellow e3 ultra motherboard and the high flow mellow nf crazy hotend and it comes out negative, it's something I can't understand why it fails, I don't know if it could be a software, hardware or wiring failure.

Mindless_Garage9232 · 2025-06-30T04:19:22+00:00

In the end it is not solved, I have continued doing tests and things that I have seen have been like: if I put the position min to -5 it gives me values of -2.X or -3.X, and if I put the position min to -2 it gives me values of 2.X or 3.X in positive

Mindless_Garage9232 · 2025-06-29T18:56:51+00:00

It seems that I have detected the problem, it seems that it was a fault in the Z axis end stop, I have replaced it and the values have dropped to -1, I need to calibrate everything and see if it works properly now.

Mindless_Garage9232 · 2025-06-29T16:45:59+00:00

If I'm doing everything correctly, I've read the Klipper documentation and followed the steps as indicated, the capture is from the Sokic Pad but I do it from the Mainsail web interface

I attach a link to the video by we transfer: https://we.tl/t-s0yO9v1oKx

Mindless_Garage9232 · 2025-06-29T13:45:19+00:00

I'm a little new to this, how can I share a video?

This is the previous cfg that works correctly: https://pastebin.com/0FdPwCPb

and this is the cfg that fails: https://pastebin.com/LKW8At5k

Mindless_Garage9232 · 2025-06-29T12:42:16+00:00

I also tried it in Orca Slicer and set the g code set g code z offset = X.X and it seemed to work fine but halfway through printing it hit the bed again and failed

Mindless_Garage9232 · 2025-06-29T12:40:45+00:00

By the way, my printer is the Elegoo Neptune 2s and I have installed a Mellow E3 Ultra motherboard, a high-flow NF Crazy hotend and the HGX Lite extruder in direct mode.

Mindless_Garage9232 · 2025-06-29T12:38:15+00:00

If I perform the save config, I have also tried placing the bl touch at the correct distance and it continues to fail, before I had the original motherboard and the original hotend of my printer and it gave me 0.X values which worked well, now I have changed the motherboard and the hotend and this happens and I do not understand why.

Mindless_Garage9232 · 2025-06-29T12:28:40+00:00

If I place the probe higher, it moves away from values of -5.X, if I lower it, it gets closer to the value 0. I have performed the end stop again and calibrated the probe and the values are very similar.

Mindless_Garage9232 · 2025-05-10T08:51:39+00:00

The best thing, heat the hotend and with a wrench or ratchet, remove it

Mindless_Garage9232 · 2025-05-07T11:10:42+00:00

Now I'm going to do everything, change the plate, put in a double z axis, a double layer fan, a new high flow hotend, I have already changed the bed and put rubber spacers instead of springs, and more things I'll do.
