I just ordered a Neptune 4 plus. It'll be shipped out around November, not sure if it'll have been updated or not but then, but if not then I'm glad I know this now! Thanks
My Neptune 4 max grinds when sending the bed to the back of the machine and my current settings are X70 Y40. Making the suggested changes and homing cause the bed to come all the way forward and the print head all the way to the left, then it tries to drive the nozzle though the bed unless I kill the power :) Very odd results for the changes, any thoughts?
If this doesn't fix your issue, check you have the right firmware too! I was an idiot and downloaded neptune 4 max firmware for a 4 plus. This made it think it was bigger than it actually was, and showed similar symptoms to what this video fixes (when you watch both parts). Most people will have more braincells than I do, but thought i'd put it here just incase.
Firmware doesn't really matter, all of the pertinent information resides in printer.cfg or elegoo_config.ini. Sure, it's easier to just reflash, but it's not impossible to change the settings after the fact.
Nice! VERY NICE! Do you have an idea what could cause the nozzle hitting the infil or other parts of the print? Like a layer is done the printer head/nozzel moves to the next spot, but while moving it is hitting the Printed part. that could cause a damage of the print or even worse kicks of the print from the print bed and after that the filament extruded after that creates a huge blob of molten PLA around the print head.
Hi, I have an Elegoo 3 Pro and I’m facing this issue on Z axis homing. When it tries to reach the upper level it makes that sound and then stops. Can you help me please? Thanks
@@TheFeralEngineer when a start the homing feature it works ok on x an y axis. But the Z axis it goes up until reach the top of the machine. It doesn’t have Z axis limit switch because it stops when touch it. But it is not working any more.

Thank you for this video. I am researching the Neptune 4 Plus as my second printer. I am concerned about the "Blob of Doom" issue people have been reporting on Neptune 4 printers. Can you suggest an unboxing process that would address this quality issue among others?
For this, go through the sensorless homing documentation from Klipper and follow the procedure to set up sgthrs www.klipper3d.org/TMC_Drivers.html?h=sensorless As for the blob of death, preheat the hot end and then snug down the nozzle, but it's my understanding that getting to the nozzle is pretty difficult on the 4.

my neptune 4 max just came in monday and i printed 3 prints 100% fine and when homing starting doing the homing issue, changed to it and now its not homing to the right spot anymore, and also my stealthchop_threshold:99999 is set to this, is that right?
Keep decreasing the sgthrs value until it homes properly again but doesn't grind. Also, slow homing down to ~20-30 to see if that helps. Stealthchop at 99999 means it's always on. Try setting it to 0 if it still doesn't home properly, but it might sound like r2d2. If none of that helps, you'll need a firmware patch.
So since i did this change to the settings, i can not get a single print to stick to the bed, i have printed a few things before i had issues, no matter what i do nothing will stick, i used the glue stick that came with the machine and i have always used the hairspray before trying the glue, only 3 settings i changed were the X Y and homing speed, any thoughts?

Just recently bought a Neptune 4 plus and I have trouble with homing Y(was able to fix the X quickly with your videos), I followed both of your videos. I went on my on trail because nothing was working for the Y axys... I did try 20mm and 30mm speed with different driver_sgthrs setting but. I first tried with +5 increments when I saw it started triggering, I went down in increment of -1.... the problem is that(at 30mm let's say, scenario is the same at 20mm...) SGTHRS at 83 still give me a big noise when homing... and at 84 bed get a false trigger moving only a few mm. I'm gonna try more speed today but yeah..(note that with the same setting of 84 I tried to loosen belt tension without success, same for 83 and correct belt tension) I'm a bit confuse. I will try to reach elegoo customer support probably today too. I the mean time do, Have any ideas for me to try? thank you!
@@TheFeralEngineer Big thank you for the quick answer, I had time to test 50mm speed and ended up with the same problem(For me belt was slipping 2-3 theeth before trigger, 123 SGTHRS was slipping and at 124 I would get false trigger and bed wouldn't move) Weirdly enough I found a quick fix! With a homing_retract_dist:5 (making it doing a second homing) the issue was fixed. I don't really get why, but no more slipping! I feel like it's just the sound of normal "bump"(unless it's suppose to be silent silent)(setting are 20mm speed and 55 SGTHRS). I'm probably missing a setting or something that make my printer want to correct his Y position in the negative(position_min is set at 0) after homing but in the meantime It won't strip my belt when homing and cause stress on the motor. If I come accross more i'll let you know!( I have a second Neptune 4 plus to assemble will see if I get the same problem)
I've only seen a new printer.cfg, not a firmware patch just yet. It's a balancing act between sgthrs and homing speed. Make homing speed 20 and adjust sgthrs based on the write-up in the link in the description and you should find the sweet spot
@@JeffreyDoesYT turn the homing speed down to 20mm/sec and start at a higher sgthrs value. 255 is the most sensitive, 0 is the least. Start at 250 and if it false triggers the homing, lower to 230 and drop by increments of 20 until it is noisy, then raise it by 10. It should be pretty close at that point.
It doesn't matter where the Nozzle goes to home, as long as when you set to level your bed it goes dead centre and that doesn't really matter ether as long as Z is set right at 0 of X and Y... My factory Home position on the bed is about an inch or so right from dead centre and it prints and calculates the bed perfectly,, you know almost 😂... I think the offset. Home position is so Z X and Y have a reference point to where dead centre is ?
It very much matters where home position is located because everything goes relative to those positions at absolute zero. Your machine goes an inch or so off center because the extruder centers the probe to the middle of the bed, not the nozzle

Is this for real? You got a new 3D printer, and you need to fix it right away? Changing those parameters, are they documented officially anywhere? How do I know it's 110, not 105 or any other numbers?
110 was the value in the latest max config I saw. It's almost the middle of the driver_sgthrs setting range (0-255) and I did mention having to possibly make slight adjustments to this number. The first batch machines need a little firmware tweaking, I just happen to know that the issue is and no, I don't have a 4, I'm just aware of the settings in Klipper because I read the documentation on the klipper site.
I have a three-day-old 4 Plus purchased directly from Elegoo with the X and Y grinding issues when they reached the end of their travel (Y much more pronounced than X). I ignored the noise and printed a great test Budha which was followed by a perfect print from one of my own files. Then I watched the video recommending The Feral Engineer and how fixing the grind would be easy. Long story short, after following the guidance to-the-letter the hot end repeatedly smashed into the bed and kept going until the power was turned off, the Y axis grinding never stopped and now I can't even boot up the printer. I get an error message on the touch screen telling me the Klipper software is messed up. Can't even open it to do a factory re-set. I'm waiting to see if I get any response from Elegoo support. Lesson learned - I should have waited until Amazon started carrying the 4 Plus because it would already be boxed up and gone and waiting for either a replacement or a refund (probably a refund as this is my second Neptune 4 that has crumped shortly after purchasing).

[tmc2209 stepper_x]
uart_pin: PB9
run_current: 1.2
hold_current: 0.8
interpolate: True
stealthchop_threshold:99999
driver_SGTHRS:110

[tmc2209 stepper_y]
uart_pin: PD2
run_current: 1.5
hold_current: 1.2
interpolate: True

driver_SGTHRS:110
diag_pin:^PB8
Hold current is a deprecated function in klipper. They suggest against using it as it can cause inaccuracy issues
@@TheFeralEngineer Unfortunately I don't know how to do all of this, or rather I don't dare.
And what I wrote in the comments was like that by default. I didn't change anything there.
@@RayZXA if you put # in front of the hold current, it'll ignore those.
Great thing about klipper is you can't screw it up
@@TheFeralEngineer Can I also simply delete Hold current?
@@RayZXA you can, yes. I like to comment things out in case I want to revert in the future.
for some reason the driver isnt on my config
Download the file and email it to me. I'll have a look

Careful mine now homes the wrong dorection
That's because you didn't watch part 2. Watch part 2. It's not homing the wrong way, it thinks it's home because the sensitivity is too high and it's trying to go to table center. Watch part 2.
Thanks I literally just found that after I posted. Might be worth pinning a comment about part 2
Ps part two you dona great job describing it
@@rpoillucci yeah, that's the difference between rushing to make a video on Sunday night before a work trip and making a video on Friday, after getting home from a work trip 🤣🤣
OMG I HAD THE STOPPERS STILL UNDER THE TRAY
Oops! 😬
Is this for real? You got a new 3D printer, and you need to fix it right away? Changing those parameters, are they documented officially anywhere? How do I know it's 110, not 105 or any other numbers?
110 was the value in the latest max config I saw. It's almost the middle of the driver_sgthrs setting range (0-255) and I did mention having to possibly make slight adjustments to this number. The first batch machines need a little firmware tweaking, I just happen to know that the issue is and no, I don't have a 4, I'm just aware of the settings in Klipper because I read the documentation on the klipper site.
I have a three-day-old 4 Plus purchased directly from Elegoo with the X and Y grinding issues when they reached the end of their travel (Y much more pronounced than X). I ignored the noise and printed a great test Budha which was followed by a perfect print from one of my own files. Then I watched the video recommending The Feral Engineer and how fixing the grind would be easy. Long story short, after following the guidance to-the-letter the hot end repeatedly smashed into the bed and kept going until the power was turned off, the Y axis grinding never stopped and now I can't even boot up the printer. I get an error message on the touch screen telling me the Klipper software is messed up. Can't even open it to do a factory re-set. I'm waiting to see if I get any response from Elegoo support. Lesson learned - I should have waited until Amazon started carrying the 4 Plus because it would already be boxed up and gone and waiting for either a replacement or a refund (probably a refund as this is my second Neptune 4 that has crumped shortly after purchasing).
@@leskeffel9512 when you say "to the letter", does that letter include the second video that I've adamantly been saying to watch? Doesn't sound like it. I said to watch it in the title, in the description and added it as a thumbnail to the end of the video.
They're very good with customer service and will get you squared away. Just remember not to make things too wordy. Keep the communication simple because English isn't their first language.
Brrrrrt
I mean could I have explained it any better? 😅😅
@@TheFeralEngineer my bad, I had first comment anxiety.
@@peperonikiller 🤣🤣 All good!
I did think of something, is there any macro/code improvements that can be implemented into the Neptune 3 Pro Klipper firmware/config? Now that you've spent time with the 4 @@TheFeralEngineer
Nothing off the top of my head
This made it worse my x z are crashing
Then you didn't watch video 2.
tu a casser ma machine avec ta configuration 😢😢
vous n'avez pas lu le titre complet de la vidéo, vous n'avez pas lu la description et vous n'avez regardé que la fin de la vidéo où il y a un lien vers la partie 2.
