I have a Mendelmax 2.0 which Ive been keeping in storage for a long while

https://reprap.org/wiki/MendelMax_2
BOM: https://docs.google.com/spreadsheets/d/1c2FuI54To9n3-B8kpy7R90FIOVTmaRYomc-zzNf7t-0/edit#gid=0

I was thinking about upgrading it to PrusaMK3 hardware, namely the Board, Hotend, heatbed and power supply.

Would this be doable? Are there any conaiderations I have to look out for?

The reasons I'd like to try this out are:
Less investment than a full MK3 kit
Higher accuracy than the MM2.0
The MM2.0 frame seems sturdier than the stock MK3

I'm assuming I can reuse most of the other hardware from the original MM2.0 kit, like the stepper motors. (Nema17)

I dont mind about the loss in printvolume.

Any input would be greatly apreciated.

Sorry, I should have been more specific.

The Rambo board sometimes skips layers and suffers from random errors, but the MK3 board doesn't seem to show these symptoms anywhere near as much. (zero, in my case after 400 hours of printing)

The heatbed rails on the MM2.0 have a lot more friction than those used on the MK3 bed. This lessens the heat generated in the stepper motor.

The extruder from the MK3 has much better cooling than the original extruder from the MM2.0, and suffers a lot less blockages.

Microstepping and trinamics aren't really a concern for me.

The errors happen regardless of me printing from the SD card, or from my PC. Back when I used the printer more frequently, this was a known issue discussed in the Mendelmax IRC channel.

Which reminds me of a couple other features I'd benefit from in doing this upgrade:
no need for endstops.

plus the MK3 heatbed is a lot less trouble to use than the MM2.0's glass bed.

How small imperfections are worth calibrating? My extruder is underextruding by 2.4% (I measured out 50 mm, and then extruded 25 mm before measuring again) and I'm awaiting the results from my 20x20x20 mm cube that I'm currently printing.

Would I risk making it worse if I'm trying to balance out such a minor (?) error?

[citation needed]
Bigdeltaguy here, it struggles over 80mm/s, while you can get an UM to do 100+ if you tune it correctly. Delta's don't get higher speeds, they can achieve higher jerk and acceleration which may give you higher speeds if you set your slicer properly. Besides, the main limit on print speed is your hotend, not your kinematics since volume flow is dictated by nozzle size, layer height (and thus how much heat your hotend can generate) and only then print speed.

>> No.1601177

>>1601159
>Could my PLA have absorbed too much moisture

It could have, but that's not what's causing your underextrusion. Judging by the amount of dust on your fan, your hotend is likely clogged.

>>1601022
>0.5 extrusion width.
You sure you set that right? Like is 0.5 an instruction to print overlaps in your slicer and not one to space the lines further apart?
Your initial squish layer went down ok so you might just be printing too fast for material viscosity at whatever temp.

Do not buy from them. I will show actual screenshots of the dispute i have going with them on an order I placed over 60 days ago. The 60 day guarantee of having your money back is bullshit and they will make you jump through a ton of hoops until you get your money back. I had ten days left so I decided to extend buyer protection, but it was the worst mistake because i now have to wait an additional 30 days, yea that part was my fault, but it's been over 60 days now and this shits never going to arrive and I doubt I will ever see my money again.

Unfortunately there are scammers among honest retailers and the system they have is inherently bullshit because the 30 day or 60 day guarantee is just on the edge of how long it takes to ship something from china. Also if a product starts racking up less than 4/5 star reviews then they just take it down and relist it.

You'll hear and see the extruder skipping if it gets bad enough; it sounds like some one tapping a wooden desk with their knuckle.

Regardless youtube how to do a cold pull and do it. Kind of hard to do on the ender 3 since you have to pull the bowden out of the extruder while leaving some filament sticking out of it, usually it just breaks instead of pulling out the crap. Do not attempt to take the bowden out of the hotend unless you want to have to learn how to reset the nozzle.

This is the response after my dispute, now mind you it's been well over 60 days now but since I stupidly extended it, had no choice really. I have to wait longer.

Basically it prints fine when using the wanhao-branded version of cura that came with the printer, but underextrudes like hell when using normal cura. Wanhao cura is utter shit and is missing a lot of settings so I really want to get rid of it.

I have a print that will consume 120g of material. I have some leftover spool ends that I want to use up. Let's say I want to do two filament changes based on how much material I have left; can Cura tell me at which specific layer I will have used a specific length or weight of filament? I would like to have a better way than estimating the layer height by looks at which to stop the machine to change out the filament. E.g. I would have two filament changes, one after 50g and another after an additional 40g

>> No.1601371

>>1601360
You could remove the filament from the spools and weight it on a kitchen scale, but the easier option, and what I do when I have a bunch of tiny lengths of filament to use up, is to simply hang a cowbell on the filament before where it feeds into the extruder. When the filament is about to run out, the cowbell drops and makes a noise, and I simply start feeding the new filament in without stopping the printer. There's a bit of stringing for a while, since retractions don't work while the two lengths of filament aren't connected, but it works well enough anyway.

A better option is to fuse the filament lengths together. What you do is take a small length of bowden tube and a soldering iron. Set the temperature on the iron to about 240 degrees, touch the filament ends to the tip, and then quickly feed them into opposite ends of the bowden tube and press them together for a few seconds.

Bought my Chiron from AliExpress, the bed coating broke within a few weeks, contacted them through AE, I got a new bed shipped within three days. I did not expect chinkshit to provide customer service at all but it surprised me.

If you buy a printer from AE, make sure it's from a relatively local warehouse and that you order it from the official store of the brand you're buying from. There are several sellers offering Anycubic, Creality, etc. But I'd only trust the ones that have huge sales volume - don't buy printers that only have <100 sold.

Roughly 100 times bigger by volume. Even if you have a strong reinforced frame you can't really run 300mm/s. That video you showed probably never reached 300mm/s because there are settings called jerk and acceleration, look them up. Only newbies think "hurrdurr high print speed in slicer = fast print" when in reality acceleration settings will bottleneck a delta as well.

Once you start living in the church of 1.2mm nozzles and 1.0mm layer heights, you too shall receive enlightenment. I have already gone beyond the 20mm3/s recommended by E3D for their Volcano with a 0.8mm nozzle, 0.4mm layer height and 65mm/s print speed, but the thing will chooch up to 40mm3/s in my setup. For reference, if that Kossel really was printing at 300mm/s (it wasn't), with a 0.4mm nozzle and a 0.2mm layer height (looks about right), that's 24mm3/s. A standard 30W hotend will run into thermal runaway protection if you shove that much material in.

I just bought a 3D printer - an Ender 3, and my print quality isn't perfect (though I'm not expecting it to be either). What do I have to do in order to increase the print quality as much as possible? This is my first printer, and I know nothing about 3D printing.

I tried printing some gears, but the teeth weren't uniform in size/sharpness, and the holes were too small compared to what I designed in my model.

Are there any tests that I can run in order to check my calibration? And what components so I have to calibrate other than the bed?

Definitely possible, I just picked the first video I saw. Here's someone experimenting with high speed and high acceleration but it didn't have a nice video to go with it: https://www.thingiverse.com/thing:2941886

>For reference, if that Kossel really was printing at 300mm/s (it wasn't)
The video didn't even claim that. It said the TRAVEL speed was 300mm/s, not the speed where it's actually pushing out filament.
>A standard 30W hotend will run into thermal runaway protection if you shove that much material in.
A 50W heater cartridge costs 2$. I don't even print that fast because PETG hates speed but I got one just so it can heat up quicker and compensate for shitty part cooling better.

My bad then, that means it's only printing at about 16mm3/s.

>A 50W heater cartridge costs 2$
And then you're still stuck with a standard V hotend which means there's not enough area to transfer that 50W into the material to keep up with 20mm3/s.

You mentioned yourself you're pushing double that.
What recommendation are you going by anyway?
All I could find was this simple series of tests done to promote their new SuperVolcano hotend:
https://e3d-online.com/blog/2019/02/28/supervolcano/

Which tells you extremely little. What cartridge did they use (official E3D V6 uses 25W as standard)? What filament diameter? What temperatures? etc.
All this shit can make a difference.
It doesn't even tell you why they settled on those speeds for each hotend. And they have every reason low-ball it there.

>> No.1601654

Because I'm using a Volcano, which has more heat transfer area.
>What recommendation are you going by anyway?
The one they mailed me when I asked how far you can push a regular and super Volcano, I wanted to know if it was worth adding this much mass to a delta (which delta's are allergic to) in order to increase print speed. They said ~1200mm3/m (20mm3/s) is the upper limit of a regular Volcano depending on your setup, but our setup seems to care very little about their recommendations. With 1.75mm PETG filament through a 60W V6 Volcano at 220 degrees Celsius, I'm getting 36mm3/s no problem.

1. Make sure everything is square and secure. Level the x gantry, make sure the eccentric nuts are tight but not over tight (the bolt through the wheel should be tight so that the eccentric nut can't loosen).
2. Calibrate your extruder.
3. Level your bed hot. Bring both bed and hot end upto your desired printing temperatures, make sure their is no errant plastic clinging to your nozzle, then level the bed with the paper method. Do multiple circuits, levelling one corner can affect the others.

Guys really.

Print quality and precision/accuracy are different things. Reassemble the printer while making sure the axes are all square to each other, tighten the belts, check for any binding on any of the axes. Some of the problems come from the warped print bed, some of which can be as bad as a few mm out in spots. The distance each motor moves can be adjusted in firmware if they really require calibration.

You should be aware though, it's a 3d printer and not a precision milling machine, it flexes and small deviations in angle between the axes can greatly affect how accurate it is. The orientation of your features and the movement of the head will also cause artifacts from inertia.

Anyways where the threads go for the display panel, there was a broken screw inside it, not a tap but a screw that would not let me screw it on. if you look closely it seems as if someone tried to drill it out, anyways i got it out. luckily threads are not fucked.

granted this was used and repackaged by a 3d printing company but they never deserved this 3d printer, so many mistakes they made. went i pulled it out the thing didn't even sit flat and had to see what was going on. nothing is square so i took apart the whole thing and started rebuilding. it'll work for sure probably better than it ever did compared to the last owner. it looks nice :)

Fire is pretty rare (but they do happen, particularly with the cheap Chinese printers 90% of us use). More common is the print failing halfway through and wasting a bunch of filament, possibly making a huge clump of solid plastic on the nozzle forcing you to replace parts.
I would avoid leaving the printer alone too much. Sleeping is fine, but make sure there's a fire alarm close enough to trigger quickly if the printer does catch fire. Also check in on the printer every now and then so you can cancel the print if it has failed.

I have an octopi, which is a raspberry pi running the octoprint server. This lets me queue print jobs remotely, and monitor the printer stats and watch it through a webcam. If I'm away, I can just surf to my IP adress on a browser and see what the printer is up to. There's also a plugin https://www.thespaghettidetective.com/ that can automatically cancel prints if the webcam looks like it has failed.

But anyway, to prevent fires number one solution is to turn on "thermal runaway protection", which is a safety feature the Chinese often deactivate on their printers. What it does is detect when power is applied to the nozzle or bed without the heat increasing, which indicates that something is wrong with the thermometer. It stops the printer from heating the nozzle up way higher than it should go, which is the cause for most printer fires.

This is great because I already have a shit ton of paint and an aircompressor. The problem with that hobby is that the vast majority of model kits out there I dislike, this changes everything.

"warm to the touch" should be fine. if you can hold your finger on it continuously then the surface is under 60C, which means the die is most likely within its 85C rating too. that's a general rule for electronic components more so than for the pi though, maybe others have specific experience to the contrary.

Stopped using it when i noticed it degrades the print quality in little more complex parts, since the USB->Arduino connection is too slow and the amount of free RAM of the Arduino is too little. I dont have an ender 3, but i recommend a friend to get a chinck Duet Maestro instead of a combination of octopi+tmc2130 for his needs and so far he is pretty happy with it, good web interface and the printer is a lot quieter than before, but keep in mind you need to know what you are doing, you dont have wifi but a ethernet and there is no webcam support.
Overall i dont regret having used an Octopi in the beginning, it was super convinient and saved me a ton of frustration by being more able to check and figure out problems or stop a print when i saw that something wasnt going well on the webcam.

In the US, recievers are considered the "firearm," so you can buy the rest of the parts no questions asked. In other countries, the barrel and bolt are the regulated parts, so right now they're working on ways to create barrels via ECM and have already made bolts out of bar stock (Shuty AP-9).
What makes this particular receiver special is that it's the only way to get replacement Tec-9 lowers (which have been known to crack), because while it's a collectible gun, it's also outdated and niche.

Yeah, imagine if we were to realize offworld colonization or warp drive. As it stands, earth has limited space and space travel is expensive and slow as shit; if you pissed off a major power there's nowhere you could go that was outside their influence. By comparison, if we were to have fast travel across the entire Milky Way, there would be an endless frontier of places to colonize, hide, or otherwise do whatever the fuck you want. Space is the final, endless frontier, and frontiers=freedom.

I can't to point any specific examples other than the DaVinci products, but those restrictions have to do with filament.

It's easy enough to compile your own gcode now, and Prusas current system where it's just plain gcode isn't secure at all, sure, but what will probably really happen is a proprietary file format and encryption. What I would do if I were an asshole is make my own thingiverse, and convert every uploaded file into my own encrypted file format. These files could only be opened in my proprietary slicer, which produces an encrypted gcode file. That file is uploaded to the printer, which only is connectable to through a proprietary, internal octopi (no USB). This lets me install firmware updates whenever I want, to make sure nobody gets past my encryption.

it's community college. you can't set aside 1 semester of classes? like several 3 times a week? sometimes on saturdays? so what. you actually spend time with actual cnc machines and simulators and there will be people there to pick you up if you fall. there is no excuse not to take these classes if you have them nearby and it will look good once you look for a job. you need a foundation for any manufacturing.

personally it should be like this

blueprint reading 1 where you learn the alphabet of lines. no one will hire you if you can't read a blueprint. im just saying.
manual machining classes, the first one was 4 units
and cam/numerical control for mill or lathe.

that's 3 classes, 10 units, that is nothing. once you are done with that you are already ahead of the curve where you can take blueprint reading and learn the basics of GD&T.

blueprint reading I think is a must, a minimum if you are getting into manufacturing parts. learning the title block, learning about revisions, some AS standards, safety, employers wanna see that you at least tried and for me it came down to the classes I took in college, I would have not gotten the job if I didn't. even introductory six sigma classes helped on my resume, like basic shit that is 6 hours long. you don't even need to know it well.

My 3nder has the textured magnetic plate. Most of the failed prints I've had were because the leveling of the plate was just barely off.
If the skirt doesn't follow the path, I loosen then nut in that direction. If it looks like it's underextruded, I tighten the nut in that direction.
The first layer is the foundation of the print. Unless you're good at fixing it on the fly, you're better off just stopping the print, cleaning up the bed and start over with the necessary adjustments.

Cetus's have fixed built plates. They're aluminum and they're fixed to a linear rail carriage with three screws in the center. I can only do so much about leveling. But leveling really hasn't been my issue. The rafts print perfectly. Their bottom layers look excellent. I might get into mesh bed leveling with Smoothieware, or possibly shimming my build plate, at a later date, but its not causing me any issues right now. The Cetus is a ridged beast, especially for a direct feeding, cantilevered bed slinger.

I will print cooler and see what happens. Also layer height, makes sense to do multiple of 4, when I did .2mm layer height, it stuck better, with less layer separation, I figured it was because it wasn't hot enough...

>>1605105
>those both were with the same print settings right?
The only difference was the infill, black was 25% and green was 95%, I meant to put black at 95% too, but I forgot and just went with it. As far as temps, and settings, they were identical.

>does the black filament crackle and pop when printed?
The only noise it makes is a snapping noise, the reason is someone didn't know how to spool the filament on, and my end piece was being overlapped I fixed that and don't hear it anymore, I am guessing you suspected that maybe my filament absorbed water?

Hello /3DPG/, I'm over from /tg/'s relatively new /3DF/ thread, basically exactly what you guys do, but focused on building a trove of files for printing, designing, polishing, and recasting Tabletop Miniatures. We're pretty basic right now, and it's pretty much just us building up the trove, designing models, and occasionally testing prints, with very little technical info regarding the printers themselves, so I'm popping in to cannibalize your pastebin, and also ask if you guys have any advice for managing this sort of thread.
Also, do you guys have an Ender 3 specific guides, especially those regarding high-detail(.1-.25mm) prints and customization and optimization? Most of us looking to actually buy a printer at this time are favoring the E3, or its variants as our first printer, as seems to be the norm, an I'd like to build as much support for it on /tg/ as possible.
Anyway, I'm more here to sort of extend a hand in hopes we can establish some sort of relationship between our two threads and communities, with /3DF/ being the younger sister-thread of /3DPG/, to the general benefit of both threads.

.1mm is going to be a clogfest, .25 is already on the small side. As long as you print low and slow, you'll be fine on the Ender 3 without customising. Most of your resolution will come from a low layer height, not the nozzle size per se.

If you want to print mini's I'd go for an SLA printer all day long, and they're getting cheap too. Given your goal though, I'd stick with E3's and a .25 nozzle, 0.08 or 0.12mm layer height and print speeds around 40mm/s.

>>1605306
Texture on the bed is fine, especially since most minis will be printed standing up, so the texture is only on the bottom, I don't see a need for glass for your purpose.
The best slicer is the one you have the most experience with, be it Simplify, Slic3r or Cura. I'd vouch for Cura as being the most newbie-friendly, although some veterans hate the UI and Simplify has some neat but different options. Also, Simplify doesn't have some Cura options.

https://www.thingiverse.com/thing:3464557 Do you mean something like this? The problem with putting the light on the extruder is that it moves around a lot and being so close you get a very bright light just on the print, and very little elsewhere. An overhead light reflects off of your walls, the printer, and the print itself, and therefore the shadows aren't so severe.
