Repairing my 3d Printer - Lessons Learned
ฝัง
- เผยแพร่เมื่อ 5 ก.ย. 2021
- If you own a 3d printer, it will eventually break. In this video, I tell a story about how I thought my FDM 3d Printer was broken. Then I broke it trying to fix it. Then I thought I fixed it only to find it was never really broken.
While this video uses the JG Maker Artist-D Pro as an example, the principles apply to any FDM style 3D printer such as the Ender 3, Ender 5, Prusa i3 MK3, ANET ET4/5, and others.

I love it! Been an electronic tech for 50+ years and still learn lessons on troubleshooting. It made me chuckle! I have been there before!!
one of the genuinely talented guys i've found on yt. thank you sir!
Sorry for the litany of problems, but it did make for a good learning experience for your channel. I think we all learned something today. Back in my day working on DEC equipment - never assume anything. The PDP-8 was notorious for bad connections in the bus, but look for burned components and bad software.
Patience is a virtue and you have a lot of it. Thanks for your videos, keep up the good work.
"Order parts ahead of time". 100% agree. Nothing more frustrating figuring what needs fixing and then having to order parts and wait for them to arrive. Obviously not major items but in my case things like heat block, heat break, heater cartridge and thermistor. Love your work :-)
I have been messing with electronics since the 1950's, and yes indeed, bad connections are the problem at least 90 % of the time. When in doubt, just disconnect and reset everything. A friend once brought me a genuine Las Vegas one-armed bandit, which just went entirely dark, all at once. I opened it up, and all text inside it designating everything was Chinese or Japanese (I really couldn't differentiate). There were not less then 30 cable connections inside, and I pulled and reseated them all. When I turned it on, it worked. That's how I got my reputation as genius.
Thanks for the great story. Seems we have all been there and experienced similar stories. It was great seeing you in the forum. Your closing remarks are right on the money.
Good information, I will add this. I have a Tenlog Pro IDEX and one of the issues I have had and still do sometimes because I forget is when I try to use the "Dual Mode" or the "Mirror Mode"
if the project your printing is too big for the build plate " For Dual Printing" my printer will just start to print lines back and forth. The printer extruders would hit each other and so the printer does not know what to do and just prints stacked lines. I will move the project to the far left side of the build plate in the slicing software "For Dual or Mirror Prints" If that does not work I may need to make the project a little smaller, and that usually fixes the issue.
I have heard great things about the Tenlog.
@@MakeWithTech The first one was DOA but the customer service was very good and they sent out a new one immediately which has been running non stop since I got it :)
great explanation and i think all of us can agree with being there before or experiencing something like this
Great video as always. Thank you.
Thank you. I've only been doing this for about 5 weeks and I was having a heck of a time last week, turns out it was a loose screw on the extruder which I swore I had checked but must have missed. It was causing small layer shift. It makes me feel better knowing I'm not in this boat alone. There are several online channels, groups and sources that have made this possible
Totally been there before when troubleshooting. This story was really helpful in outlining a methodical process, I'll keep this in mind when I buy my next printer which will be an IDEX one. Thank you.
You are amazing as always! Thank you for your time and patience.
great tips. The main reason I went with the Prusa i3 kit vs assembled, was to become familiar with it before I have to troubleshoot.
I agree. However putting together an i3 Mk3 is a painful exercise.
I’m following a couple RC 1/10th scale truck building channels where they recommended the i3 kit, so compared to working on RC kits , I found it rewarding and took a couple weeks of casually putting it together carefully following their excellent instructions with the online comments. But if I had the expectation that it was some assembly required and it would be up and running in a couple hours, then I agree it would have been painful and I would have likely made more mistakes trying to assemble it in one session.
Thanks for sharing. Great info.
Thanks for making the distinction between "broke" and "broken". I'm not an English major so I completely missed that.🙄 But, irregardless, good video. Thanks for the logical diagnostic flow. Keeps people like me from going down rabbit holes unnecessarily and reminds me it's ok to ask for help.
This is correct. I was wrong. I am an engineer and should have taken additional classes in grammar.
Haha.. Irv im new to all this and find your videos highly informative and appreciate your time so thank you! Last night i was very carefully trying to remove a tiny piece of plastic off the nozzle(5 pro) and jammed my tweezers into the fan. Some laughing and realising how stupid i had been i then decided to order another one... And not be such a womble next time... Lesson learned. Have a great day.. 👍
Great experience.
What watch are you wairing? Great channel
I agree do not think the thing you think is broke is the problem. Slightly off topic our car showed an engine issue but it was a faulty brake sensor?
I have a JG Artist D Pro 3D Printer. But it isn't easy to get replacement nozzles in the USA. I have to wait about 20+ days before receiving my order. The only nozzle available from Amazon is AP 0.08, shipped and received within 6 days. I am thinking about what I will do with my Artist D Pro Printer.
Irv...Great video! These help tons! Looking at dual extruder printers and my choices are this and the Neptune 2D. Thoughts? I like the 2 extruder model better then 1 head with a purge block. I'm thinking of the waste the purge block uses. Any suggestions would be appreciated! ~ Lou
I also prefer the IDEX dual extruder architecture
Since I saw your video on the JG Artist D Pro IDEX, I have been wondering whether it would be up to doing Polypropylene with Glass Fiber 30% while using water soluble support mat'l. Would you comment? I know there are no hardened steel nozzles, but the brass replacements aren't expensive
It depends on the temperature requirements. I would not use this printer above about 230c.
the lesson from this an engineer can design and code machinery but it takes a technician to repair them. totally different mind set
Irv, quick question for you. I got some of the super lube you suggested in one of your vids and applied it to my Z rods. Is there anywhere else I need to apply it to? I have a Creality CR6 SE. TIA! 😀
That should do it.
Put some on your door hinges, lasts for a looooong time
Hi, I love your videos. I have an Ender 5. Should I put away the reel of filament I was using once I finish a print? Should I cut it of at the extruder, or pull it out of the tube? etc? I haven't seen anyone mention this. What do you do/think?
A lot depends on the type of filament and the time it will be idle. If it is PLA you are probably OK, PETG or ABS or any other water sensitive filament should be stored in a dry box.
I usually am printing on my printers every day, but if not using them for a while I will remover the filament and store.
@tradde11 How do you remove it? Just pull it out? Cut the filament at some point?
@tradde11 Thanks. What printer do you use?
@tradde11 OK. thanks. I think I'll follow your advice on how to remove the filament... I'll let you know how it went.
@tradde11 How hot would you recommend?
Make sure you have written down the off set measurements you get when calibrating the left and right extruders. Then if you have to re set to factory defaults you should not have to do the whole calibration again
I just got new desk and noticed the whole desk shakes when I'm printing...I thought my printer was jacked up at first. My printer probably still needs to be tuned, but now I'm aware of the vibration in my desk too 😂😭
Yep. Printers that move the print bed back and forth in the y axis do shake a lot.
Can my ender 3 run from my laptop?
How can I see what is on my SD Card to check for firmware? (Using my Laptop)
I see a lot of printers in the market for sale now. Also I have gotten some because people can't use the or print. Because of small things and don't know how to use them. I Think we need to go back to the beginning for new beginners.
And I think need to fix there printers so they are not broke.lol. But yeah great video.
So it remembers the mirror or duplicate even if you power cycle? It shouldn't because that is not the basic state. I agree it's a bug.
When you set the x mode to mirror all front panel filament movement comments are directed to the left extruder.
in my days we called that « broken as designed ». When at the control panel the machine should do what you ask, not wathever it wants to do.
HINT HINT HINT :)
Hey Irv, Thanks for great videos, quick lesson learned from me. I noticed a lot of under extrusion and i ensured all slicer settings had 100% extrusion and still got under extrusion. However, long story short, i cut short lengths of filament and pushed into the filament sensors, then i created a clip that goes over the top bar, one for each filament feed, then it acts as a guide and bypasses the sensor. No more under extrusion issues. I have a feeling it created just a little TOO much drag!
Just a hint -- different filaments have different characteristics even if they say it's the same material( e.g. PLA, ABS, etc). You should always re-adjust your settings if you change filament. Even 2 different colors of the same e.g. ABS or Nylon from the same Vendor can have different E-Steps settings. Wrong E-steps will definetly result in over or under extrusion. Also, sometimes you need to have different than 100% flow setting for Cura to deal with the same issue.
@@krukhlis yeah definitely. I have used the same type of filament for the last 4 years. And printing since 2010. Even colors in some cases have different characteristics of the same brand
This is definetly a firmware bug and the vendor should fix it. But yes, the first step if you can't understand what's "suddenly" going on -- reset to default and do step-by-step setup, changing and checking 1 item per step. Also, the first thing I do when I buy new printer or when my friends ask for the help with their -- check hardware and electronics. I had fantastic experience helping my friend with chinease clone of the Ender3 that has 2 motors for Z-axis( Ender 3 has only one). And some *diot set different voltage( which means different current for motors) on drivers. It was 0.7V and 1.1V. Gues the behaviour of the Z-axis. 🤣 Also, one motor was extremally hot.
Another situation was wrong stock GT2 belt routing for CoreXY-based printer. So the printer X axis and Y axis were moving ok in some directions and wrong in another.
When you cant get something simple to work with your printer it is infuriating but when you fix that problem it's like all your birthdays come at once!
I thought grammar was grandpa's wife!
It's blue smoke that makes all these things work properly.
When the blue smoke leaks out, you've got a problem.
Hello Irv. Broke is a simple past tens isn't it?
I’m an engineer and should not share information about grammar. Yes it is broken, it broke.
Use the process of eliminiation. 50% of the time it works every time. :o)
Broken is a feature a bug is a handy thing a programmer thought necessary lol
Nice man much to slow for me dont hate kinda like reading a tom Clancy novel
First! Thanks Doctor Vax!
I bought two, one arrived damaged, loose electronic parts came out from inside the printer, I have been waiting for parts for ten days, it comes from China, no stock in the USA
the other is working, both of them I had to completely disarm them, adjust the y and z rails,
after going through thousands of problems, it lost its calibration, a Z motor froze,
I have the same problem with the right extruder, in my case when I want to work the right one works the left one, you can see that it is something that happens to many of these printers
They are a headache, if you like to fix them more than print it is the perfect printer

This sounds like pretty bad engineering. You do not change wiring like that without guarding against accidental use in a previous version (ex. by changing the connector and having some required gap at a certain position to mark the correct versions matching). That said, when in doubt, the first suspect should be the user (so you), the second is the software (so firmware or settings) and only then hardware. Now, I would expect that in your case the firmware (Marlin) should have given an error when trying to extrude with the second extruder if you would have sent gcode to it manually as it apparently should have been in a mode where it would think there's only 1 extruder (as the second would just mirror or clone). If Marlin doesn't do that while not allowing the control of it, I would expect this is worth a bug-report on Marlin.
right now printers are almost there, but not yet. way too many variables for the average hobbyist. greed has caused a tidal wave of barely tested models that can be a source of great concern to most of us. maybe in a year or so, we'll see a more highly developed platform with greater reliabity. until then, only a dedicated tinkerer, would find pleasure in owning one.
Yep
I do like your videos and they're informative but you talk way too slow and way too long. I'm 69 and I feel I age a year each time I watch your videos. Speed them up and get to the point sooner, I haven't got much life left in me to continue with long videos! LOL. Thank you for the videos anyway.
