    Hello everyone!

    I am looking for advice on how to begin with the printer. My dad had that printer and I am looking to take over his work. Sadly, he is not here anymore to show me how it works…

    So I know he was able to print a lot of things, so the build worked. I just don’t know what software it needs, how to do anything basically.

    Also, I was wondering if anyone made a full enclosure for the printer. I have two cats and I just know they will mess with this.

    Thanks in advance! 🙂

    Lets see pictures of what you have, the entire printer itself, the hot end, and the control board.

    I’m sorry to hear about your dad. We’ll help out where we can, and you should be able to get it going. I’m interested in seeing the pictures, like Ryan said, and as for the enclosure, a cardboard box will do in the near term, either plopping it over the top, or putting the whole thing in one, and just closing the lid. It’s a common suggestion when people are having wind or the environment is getting too cold. After you get some printing, another popular solution (for most printers) is the ikea lack table. There are several parts on thingiverse to make brackets for doors and such. I haven’t measure it against an MP3DP though.

    Hello Francois,

    Very sorry for your loss, I hope you’re doing okay 🙁

    Beginning in 3D printing is a bit challenging, there are lots of stuff to learn, but it’s not actually very complicated and once you’ll get it it will become super easy.

    Basically, the first thing is to get a 3D file of the object you want to print. Since I don’t know if you’re able to design yourself, I suggest you first to go on the website http://www.thingiverse.com and download a “.stl” file of a commonly printed object, like this one, which is ideal for testing: https://www.thingiverse.com/thing:763622

    Then, depending on your situation, you’ll have the following options:

    -Do you still have access to your dad’s computer? If yes, I suggest you to use it so you will have all the configuration he already did for the printer, it will be way easier for you. In which case, try to find the printing software he was using, might be Cura, Slic3r, Simplify3D, Kisslicer… those are the most popular ones so there’s a good chance it will be one of those.

    -If you don’t have access to his computer, then it will be a bit more work, you’ll have to download one of those softwares I just mentionned (in my humble opinion, Kisslicer being the best of the bunch) and you’ll have to configure them for your machine (input the dimensions, the nozzle diameter, the temperatures, infill percentage, and so on)

    Then import your 3D file in the software, find the “slice” button and save the new file in an SD card.

    Put the card in the printer and navigate in the menu until you find your file, then hit print and let the machine do the hard work.

    I suggest you to spend some time on Youtube to watch as many tutorials on 3D printing as you can, it will be way easier to understand the process than reading forums.

    Anyway, good luck and don’t hesitate to come back here if you’re having any issue along the way, if the machine used to work fine then it should be pretty easy to make it work again, most of the hard work is already done!

    First I am sorry to hear about your Father.

    If you want an enclosure I like the suggestions given in this video.  This is for a different printer but it should fit.  This is the same IKEA LACK table design that Jeffeb3 mentioned.  But the tent in the video should work as well.

     

    For advice and help you can ask any questions here in the forums.  I may also suggest checking a local library.  Many of them have 3D printers and they have people that can teach you how to use them.  If you setup a time to talk with them they might be able to help teach you any number of tips and tricks.  I prefer to learn from YouTube but that is just me.

     

    To get started.

    You will most likely use Repetier host as your computer software.  It is a free program that can convert 3D files into the Gcode your printer will need.  Repetier host can also connect to your printer and control it manually.  Here is the info page to set that up.  https://www.v1engineering.com/repetier-host/

     

     

     

     

     

     

     

    So please.  Feel free to ask any other questions and I think we can walk you through it one step at a time.

    Hi guys!

    Thank you very much for the help! I have ordered the photo tent and will be building that LACK setup, it’s pretty cool!

    Here’s a first picture, will have more tomorrow 🙂

    Thanks a lot!

    That is a nice printer. Bltouch, filament runout sensor, Mk8 extruder, custom bracket for the filament.

    It’s a version 1 of the mp3dp. Please also take a photo of the controller. You’ll also want to know what filament you have, or just order something of known quantity.

    This is going to be a challenge, to give you the info you need. But it will be fun. I hope you’re ready on your side, because information is going to come like a firehose.

    I agree that is a nice machine.  I also noticed the Build TAK on the bed.  Nice.

    The controller Jeffeb3 mentioned is the large circuit board that all the wires plug into.  We want to know what Brand, type, version you have so we can give useful advice and instructions.

    The filament you have there looks like PLA to me.  Normally you can’t tell from looks but PLA is the only filament that I know of that gets brittle and snaps when it is left to sit for a period of time.  If that filament is easy to break with your fingers then you will want to just throw it away and buy some new filament like Jeffeb3 said.  Word of advice.  Pay attention to brands.  It makes a big difference.  The cheapest filament you can buy will usually give you the worst results and make for a bad experience.  I have been slowly switching my filaments to Prusament where possible.  They are usually About $25 a spool and they aim for top quality and consistent diameter.  There are a lot of good brands though.  Just read user reviews.

    Fun note for anyone interested.  If you are not sure if a filament is PLA or ABS you can light it on fire.  ABS will burn dirty, smokey and drip black molten fire balls.  PLA will burn cleaner and smell like something organic almost like a corn smell.  I have no idea what PETG burns like.  Hmmmmm.  If you read about a residential fire in Colorado that might be me.  🙂

    Hello everyone,

    Here all the pictures I have taken and some info I found.

    I think the board is a Rambo something, not sure… The small display is a Marlin something…

    I saw that my dad was using Repetier to drive the printer. He had a config for Slic3r and Cura, not sure which one he used. I know that he had a tool or a sensor that could check at multiple position on the bed if it was leveled and adapt the Gcode to make it work.

    Also, he received that Ziflex thing, I think it goes on the bed to make it easier to remove printed pieces. Don’t know if it work with the heated bed though.

    In one of the pictures, I took the bed pretty up close to show that the bed is damaged there.. I don’t know if that can cause any trouble and how to fix it.

    Thank you so much guys!

    And also, I’m not sure how to calibrate and what to calibrate. Even more with the auto leveling thing.

    Thanks!

    Make sure your mosfets do not touch on your ramps board, they look awfully close together!

    These guys. If the silver back parts touch, something will smoke. I thought the same thing.

    Ok so I moved them apart so they would touch, but one of the two brown things began to smoke anyway… Is it just dead? 🙁

    Yup, that one is toast, and not the tasty kind. 🙁

    Looks like you dad put a fair amount of efort in to get the best printer he could out of this design. The level sensor is either a BLTouch or a clone. If the black stuff on the bed is magnetic then you just put the nice clean surface on and print there. Verify first none of the bad stuff sticks up at all. If the magnetic surface is actually two pieces, the magnet and the print surface, you’ll want to peel the other stuff off before installing. You don’t want to try printing directly on the current surface, those rips will just be a headache.

    Oh, bummer. Those are fuses. So something must have shorted. It would be nice to know what shorted to cause that. I think touching mosfets would do that, but did it smoke after you separated them?

    You’ve got a few options. You could buy a ramps 1.4 board, which would be the easiest. You can keep the wiring the same and the software on the arduino will stay.

    You could also try a mini rambo, which is more tolerant to things like this. But you’d need to flash the right software for things like thw bltouch and filament sensor. More complicated, but you’ll learn a lot and you’ll end up with a good sense of the printer. Definitely more work though.

    This I a quick video that shows how that Ziflex should be used.

    That layer on your print bed right now could be part of this Ziflex or it could be the old build tak that got damaged so he was going to replace it with the Ziflex.

    Quick thanks to all of you guys! I rarely saw a community that supportive ! 😉

    So I ordered another ramps 1.4 board, will replace this tonight and I will make sure nothing touches !

    It started smoking when it was heating up the bed so I didn’t have the chance to print anything. I’m pretty excited!

    Will update you on how it goes!

    Thanks again!

    Ok so I installed the new ramps board. Plug it in, sees it, but It seems there is something wrong with the motors of my axis. I am able to move it up and down, but not too much. If I do a 10, it moves a little, block and does a weird noise that I don’t like.

    Also, on the X and Y axis, when I try to move it (Always in the Manual control in Repetier), it makes a noise like it hit something, but nothing moves.

    I am pretty sure I plugged everything back the way it was…

    Thanks! 🙂

    Never mind, I forgot to put the jumpers from the old board, moving like a charm now 🙂

    Now I just think the extruder is clogged or something nothing is getting out. When it’s heating, it seems to drip a little but during the actual printing nothing comes out.

    Also, the filament sensor is a bit weird, I can’t get the filament to go through it.

    Thanks again! 🙂

    Great!

    The firmware will keep the extruder motor from running if its cold, so you should preheat the hotend and try to extruder using repetier host. Just extrude 5 mm or so. It should pull in 5mm of filament from the top. You can also push down on the lever on the extruder and then push or pull the filament to change it out. If this isn’t working, just post a quick video of what’s happening and you’ll get a few opinions on what’s wrong.

    Yeah, when it gets stuck due to a little clog you can just push some filament through to get past the bad spot, but if there’s been oozing between the bottom of the PTFE tube and the throat you have to pull it all apart to repair.

    IT’S ALIVE! 🙂

    Thank you so much guys! I’ve been able to print a couple of keychains for now 😛

    Now I just have to tweak and play with the settings. My dad had configs for both Cura and Slic3r.

    Thank you so much again guys! 🙂

    I’m pretty impressed with you getting this thing working. It’s far from having a manual, and I would expect very few people could get one of my printers running if I wasn’t there to explain the many “workarounds” I’ve made.

    Before too long, make a backup of the slic3r and cura settings, and if possible, also try to find the Marlin folder that was used to flash it. When you connect, it will often print a date of when it was compiled, so the right Marlin folder will have similar dates, probably.

    It’s not that I don’t trust your cats. I just don’t trust any cats…

    Alright thank you! Already did backups of all his files. I will check if the firmware is there. I started to look at the Cura standalone software. I’ll try some prints with it see how I like it. For the cats, for now they are afraid of it 😛 But I will do the LACK setup pretty soon.

    Here’s my first prints with Slic3r. Anyone has guidelines to print DnD minis with a stock 0.4mm nozzle?

    Also, I find that I have better results when having higher temp than was is written on the PLA roll. Often have adhesion problems.

    Thanks again

    The temp sensors are self consistent, but I believe they are all different in an absolute sense. I wouldn’t worry abot 5-10C above the recommended.

    Detail is something I’ve never been very good at. I also think there is often a lot of post processing on models like that. I think smaller nozzles and geared extruders help, but I haven’t tried them yet. Slower speed also usually helps everything.

    If you’re having adhesion problems, you can try to add a brim or a raft.

    The 3D printer you have is an FDM (Fused Deposition Modeling) meaning it melts plastic and adds it one little tube shaped extrusion at a time.  Great for larger prints, cheapest type of printing on the market, the problem is the fine detail  you can get fine detail but you will have to test tons of variables to tune it in. Speed, temperature, extrusion flow rate, filament type and brand.  Then your printer may need to be fine tuned: belt tension, bearing play, steps per mm, nozzle size, etc..

    Essentially you want to make sure it doesn’t wiggle or move unexpectedly.  Any minor movement like that will cause those small lines you see on the printed parts to be larger.  So you would need to do things like sanding or vapor smoothing afterward. It can all be done but it is a lot of work.  You can search YouTube for details on all of these things.

    I will suggest to you the same thing I suggested to my coworker.  For DND miniatures use a different type of 3D printer.  Liquid resin.  Preferably one that uses a high def LCD screen (but lasers are great to.)  Like this one .

    I have a few 3D printers. I use FDM printers most of the time. But for fine detail I use my SLA printer.
