I just ordered the Elegoo Mars Ultra 4 resin printer and the Mercury Plus Ver 2.0 2-in-1 post processing wash/curing station. Can't wait!

Wow, 18um resolution in the XY directions is crazy precise. Nice.

Yeah, that would be 0.018 mm, and my Neptune 2 gives 0.1 mm resolution. That Mars Ultro 4 gives over 5 times finer prints. Nice.

Among other great specs like the printing speed.
Quote from: JKnightandKARR on Jul 19, 2025, 03:15 PMAmong other great specs like the printing speed.
I didn't even notice the speed.
Quote- 7-inch 9K mono LCD
- 8520x4320 resolution
- Up to 150mm/h
- High-Speed Wifi Transfer
- Powerful Linux OS
- 4-point leveling system
- Build volume of 153.36x77.76x165 mm³
Up to 150mm/h?!?! Yikes! Something is rotten in printer-ville. To print at only 15 cm (about 6 inches) in an hour is useless.
There must have been some kind of misprint. What is the "real" print speed?
Well it says it takes 1.5-2 sec for each layer since uv light is involved. Compared to FDM that seams really fast.

Hmmm, yeah, those resin printers do not actually move a filament head, so that kind of speed would be meaningless.
When are you supposed to receive it? I would be interested in a comparison between the two printers printing the same thing (maybe a benchy.) How does the speed compare? Is the much smaller resolution really that much nicer? How much does it cost for the resin versus for the filament? Although at less than $200 for the resin printer, that may not be so important. However, I do like the size of my Neptune 2. 8)

Right now elegoo has sale going on. I got mine, open box for like $166 i think? That's good idea. Can do that when i get it n figure stuff out.

Isn't that how it works? That and 10mm sockets... lol
Well, I got the printer today, post processing, tomarrow, anyhow, there's 4 diff slicers on the included flash drive, interestingly, there's a USB port in front, probly just for loarding files, or with the built in WIFI option.

So, no cable. No resin, so I have to get some, but it has a range of tools/accessories, including an air purifier that plugs into the top. Gotta read the manual, not too big, just gotta figure it out, might take alittle bit...
Reason is, bad news, my 17yr old pup Gizmo, might be E.O.L.... heart murmur, dehydrated, arthritis, and well, on meds now for kidney failure, so kinda off my normal mindset... We are hoping and praying to God that Gizmo will make some kinds recovery.
Anyhow, I loaded the included Rook file into both of my slicers, Mars 4 Ultra set to 0.05mm layers and Neptune 0.06mm, estimated print times:
Mars 4 Ultra: 2h, 33min vs. Neptune: 6hr, 11min, so quite a bit different. The model dimensions are: 29.86mm x 29.80mm x 50mm. The resins appear to be comparable to FDM printer spools.
Photos to come.

Sorry to hear about Gizmo's poor health. It's rough when a loved pet dies - I remember when our dog, Hines (named after my daughter's favorite football player,) died - rough time at our house. After our daughter moved out, my wife took over care for Hines, and he was her pet - she had an especially rough day.

One of the nice things about my new Voxel is that it comes fully assembled (even brand new, not just when bought used.) My other printer (a Neptune 2) took several hours to assemble. Plus I never got it dialed in - didn't help that I started packing to move almost immediately after getting it assembled. :(

This one really is nothing to assemble either, just screw ant on n insert the purifier, the build plate don't realy count since it comes on n off.
I hope "Gizmo" pup is feeling better, with the new medications.
And, thanks for posting about your new Elegoo printer.
Seeing new toys tools is always interesting.

Not much here, manual, power supply, turn table, tools, cleaning vat w/basket and the unit itself. Looks pretty simple. I guess from what I read, 93% rubbing alc to clean with.

Oh yeah - my post came across as contrasting my new Voxel to your Elegoo. What I meant was to contrast my Voxel with my Neptune 2. The Neptune will print much bigger items, but it takes up a whole lot more space on the shelf - that is why my Neptune has not been unpacked since I moved into this house.

Oh I know. lol Still not bad compared to my first printer.... Printrbot 1405 SimpleWood.... NOT a good design.... Bolt the frame together, but let's have the axis bearings end to end, ziptied on using 4 in long zip ties.... REALLY?!?! Needless to say, Y-Axis sag was at least ONE INCH..... the only good parts were the electronics..... frame is flat out crap as far as being reliable....

More like streching things.... wood didn't bother me, but bearing should been spaced out.... not to mention held inplace better... but othee then that it was good.

First print. Says Rook, but it's more like a castle tower, printing Transparent Red, so will find out how it looks. Think layer height is 0.05 I "THINK".... still trying to figure this software out... easier said then done.
Edit: 80 layers in 920 layers left and time is 12 min no idea on seconds in.
Short video containing, a function demo, a general overview and parts online. 475 layers in 525 layers left at 1hr 4 min.

Probly not. Lol. Like i said. No visible layer lines. The Elegoo slicing software is laggy so far all kinda tricky to figure out...

REALLY nice feature that resin has Vs FDM printers. I initially only had the tall model, 8hr print time. I added 2 more and STILL the SAME print time!! It's pretty nice that the only thing that would increase the printing time is making the print taller!
Very cool! 8)

Well, I've used the Mars Ultra 4 for a few prints now, inc. one big part that BARELY and I do mean BARELY!!, fit inside the print area, and I am pretty impressed with how easy it is to use, minus when I attemted to fit that big part into the post processing for curing. Had to rig it up. Wasn't easy, but so far, no issues at all. Just a bit messy when cleaning up. I always dump resin back in bottle n wash the vat and print surface up before calling it done. I just printed 2 brackets for my Neptune 2 printers to mount BLTouch or similar touch sensor. Thinking about a kit from Amazon, bout $35-$40. Creality, similar sensor, but has metal non replace probe vs plastic. Downside is Creality's CR Touch I'd need extra cable to attach to my printer. Found a video on putting it on.
Just gotta watch it n figure it out.

Is that Amazon kit for an auto-leveling option for the Neptune 2? One of the troubles that I had with my Neptune 2 is trying to get it leveled - it is a royal pain to get the screws set right. If I recall correctly, I saw something about an option for auto-leveling, but my memory is not that trustworthy for something from 2
1/
2 years ago.
Do you have a link to that kit? Does it give all the parts needed for the leveling option, or does it require more?
I just finished watching the video. It looks easy enough, and I'm not sure that I share his concerns about the auto-leveling on the Neptune 2.
If that Amazon kit of yours is cheap enough, I may buy one when I get back to working with my Neptune 2.

Pretty much, from what I understand anyhow, is any touch sensor, the documentation said BLTouch, though the Creality CR is a direct replacement, just need the sensor, wiring ext, screws, and the mounting brackets can be printed from files in their webaite. I know gotta do little work in firmware n update it. I got watch video, but touchless I am going to look into and try.
