Prusa Mini Day 1: Getting a good calibrated first layer that sticks to the bed, and assembly tweaks.

- Straight from the box, I had some pretty serious issues after my initial setup. I could not get the first layer properly calibrated, and the fancy prusament PLA would not stick to the bed. I also had some assembly issues that caused some concern. Luckily, these were all pretty well-documented issues that were quick to fix!

Thanks for sharing your experience! Running into some similar issues which I'm working through 1 at a time, but refreshing seeing you come out the other side on this!
I was pretty bummed when I cranked up my Mini only to realize it didnt work out of the box. I left it sitting for a week checking online off and on for solutions. Then I found this video and now that I have a better understanding of what's happening I'm motivated to get it working. Thanks for the info!
I feel ya. But after a few little adjustments, it’s perfect and I LOVE it.
Thanks for the tips! Still waiting for my mini to arrive but looking forward to getting printing.
This was incredibly helpful. We were suffering the exact same problems you mentioned.
Thank you very much, this morning i felt like I was lost after 4 failed attempts of a design that have small objects, you just solved my problem 🌹🌹
Thanks for the info! The test square and tuning eliminated my layer calibration issues.
Great suggestions with the Soap and the sample print. worked like a charm, learned my alignment was way off
AWESOME!! Man you saved the day!
I've got my mini just about one week and it has exactly the same issue.
Thanks for the video, just got my mini and got the same issues. I shall go through your tips today. Thanks again.
Thank you so much for this video! This is my first printer and after the stock calibration thingy I thought that youre supposed to have gaps in the first layer and wondered why everything came off during printing after a while. 🤦♂️
Now everything is 0.15mm lower and prints perfectly!
Thanks Rob! I love the simplicity you brought to this, the way you explained it really just clicked and made sense. I'm already going to get the flat sheet part you posted, that's a great idea/helper tool.
When I found this video I had just got done doing the things you recommended, I've also had to up my PLA temp by 15 deg for some reason and I'm still not completely satisfied with my prints yet so I'm still looking for more solutions I might not have thought of.
But I think you should do more of these, you explain what's going on and how to fix it so everyone can understand it without adding confusion to the mix and though it's simple, it's perfect. I wish you did all their troubleshooting videos! I'll be checking out your other videos for sure.
You can also create a flat sheet like this quite easily directly in prusaslicer only takes a couple of clicks
@@felixkolk4948 How? What are the steps?
@@neilapolitan right click in parts area New part-> cube uncheck the scaling lock change z to 1mm
Now you place the cube in the area of the bed you want, repeat for the other corners
This video was a huge help to me, thank you so much for the z height tip! Way easier to configure.
Cheers for the info! Now I have the confidence to go out and try one of these!
Splendid summary. Big thanks!
Thanks for pointing out the adjustment print by jeffjordan, that really showed me that I was printing just a piece of strings instead of a uniform sheet. Hope that my prints will stick better now! Interestingly, I have exactly the same experience with the Mini, first print worked flawlessly and then the second day, things started to go wrong and prints would warp...
You solved my mini problem. Thanks so much!
Awesome VIdeo. No fluff just useful information. Thank you!!!
Dang that link for that calibration and adhesion square doesn't load...
Thanks a lot for awesome tips. In my case I found that my table was little wobbly and contributed to the prints getting off the bed midway.
Wow thank you for this. I wasn't sure if mine was calibrated or not going to try the squares tonight
Thank you for the tips! I spent a few hours today trying to get the print height correct. Hopefully the square pattern will help me get it locked in.
Just found your channel and subbed. I have a couple more moths to wait for mine but hopefully I remember this video!
I've always found wiping my print beds with paint thinner applied via an old sock works wonders. That's what I use to do on my wham bam sheet on my ender. Haven't had a single problem with my prusa plate sticking on the efirst run. I'm kinda conscious about only grabbing it on the edges too.
Thank you, I got an MK3, I got 3 good prints and then nothing worked. You give me hope.
This is awesome thank you so much. I really appreciate it!
Been scratching my head for a while thinking about what's wrong with the printer. The first layer doesn't stick well I've wiped it with IPA every time before printing and still had the same issues with the adhesion..the first layer calibration procedure in Prusa menu also doesn't give a consistent result. glad that I across your video.
Thanks for the vid!
fixed me up! thank you!
Great video. I use Windex or similar to clean my glass and build-tak like surfaces. Based on the humidity, I still may need a bit of gluestick :)
I had the exact same issues with mine. The couple of first prints were ...OK... But after that Things started to sail off. Ha to rebuild the hot end and readjust the extruder. It prints decent now, but I'm curious to try your first layer cal.
Very helpful. The files you linked to are not there anymore, but I found similar ones on thingaverse that did the same thing. My printer is finally dialed in now. Thanks for sharing.
Can you share the links?
Stuff works pretty well for me. However I do wonder if I should not try to run one of those tests. I had one print that I stopped that I really thought was way too low.
Just got my prusa mini it is a beast it prints very well
Sorry for my English
Thanks for the video, even as someone who knows barely anything about 3D printing I can tell that default zigzag pattern is so unfit for purpose, Im surprised that almost 1year later it still ships with that as the calibration test
i think everyone that has the mini has the same issues lol nice work getting it all fixed up - out of all my machines this one is very fiddley but prints great - i to had to fix the hotend gap - and loosen the idler screw - u should also change the ptfe tube inside the hotend for a better grade like capricorn tube and get the textured bed - it makes the prints look even better !!!!
Thanks so much.
Complete noob here but in hindsight the tip off for me should have been I couldn’t get the first layer z setting low enough even at -2.
Is the 3x3 calibration layer meant to be solid? I see you're showing a bad one that is basically just a set of strings in a square not fused together. Does the right calibration yield one that has the entirety of the square fused together?
Thanks for sharing the info. First time Prusa user, I have a question. Will I have to first layer calibrate when I change from one PLA color to another?
you shouldn't, unless you change the steel sheet.
Smearing hand grease on the print bed does not help indeed? It works like a release agent. I work in aerospace composites industry and wearing nitrile gloves is standard practice. Should be done at 3D printing as well. Prevents a lot op problems.
An Wira ooh! Good idea. I already have a couple boxes in the shop, I’ll be sure to glove up if I need to handle the sheet!
@@robrobsworkshop Nitrile gloves aren't really that necessary just handle the sheet by holding the edges instead of touching the face of the sheets. Every month, you should clean with warm water and soap. Before every single print, wipe the sheet down with Isopropyl Alcohol (more than 90%)
Edit: You should also wipe the sheet down with Acetone to rejuvenate the sheet.
HDR20 Films yeah. Since washing it I’ve managed to avoid touching it entirely. Monthly cleaning sound good. For the past couple days it’s been smooth sailing with daily ipa wipe downs. Gloves seem like a good idea if I find myself to paw at the thing a lot but yeah, being a bit more careful and not touching it to begin with seems like the best bet! Thanks for tips, acetone is like, the one solvent I don’t have on my shelf, so I will grab a small can next time I’m out and about. I have heard you don’t want to use that tooo much though, correct, just periodically if it needs a little help and soap and water aren’t working?
@@robrobsworkshop Yes, I usually would clean it with acetone every 1-2 weeks and clean the bed with warm water and soap every month or so. You should check out Prusa3D's video on begginer. You should also check out the reddit subreddit r/prusa3d for more help in case you're in trouble. They also have a discord too if that's perferrable to you.
Hi, do you happen to have a new link to the 75x75 test file? All links in the comments no longer work. Thanks!
any links to those calibration squares?
Do you think some of the issues are worked out now, im about to order the Mini+
What’s the odler? Did I spell thag right?
Im about to return mine!😢
Thanks for that info But I am unable to locate the test print Tried doing one myself No Joy
Thanks and Stay Safe
ty
Awesome
Half an hour work after researching online for a few days... Super easy, right?
Could you go into a little more detail on how you dialed in the test square? i looked at the ttlexceeded article and couldn't follow it. Thanks
My Drone Stories I’m traveling this weekend and not in front of the printer, but once you start the print, one of the menus has an option called something along the lines of “live z adjust”, and when you select that you can dial it up or down accordingly. You should still follow the instructions/guidelines in the manual, it’s just easier to see in the large square shape than with the factory included test shape.
4 months you had to wait!? Wow. I only waited a week for my kit 😅
Those look like the exact problems I'm having with the i3 MK3S+. I'll give these tips a shot!
Dawn. Effing. Dish soap. I'll be darned it's working on my i3. Thank you so much!
After I started using acetone I never use alcohol anymore to clean my print surfaces.
To me, a lot of the struggles with the Prusa Mini come across as superficial, as most of the builds I've seen were by makers with CNC experience. In other words, many reported issues seem like content for content's sake.
Tubers gonna tube :D Anyhow, I can't really speak for anyone else, but as someone who is relatively new to both hobbies- when the third failure in a row happened, I momentarily was worried that I might have hours of troubleshooting in front of me, but was pretty relieved to quickly learn it was all pretty simple stuff.
I’ve had a few issues with mine, but I agree with the video: nothing that hasn’t been too tough to fix. This is my first 3D printer ever, so I really didn’t know what to expect going in. I had some adhesion issues with PETG, and some x axis issues, but in both cases there were posts over on the Prusa mini forums that pointed me in the right direction.
Sorry but where did i find the promised Link of the Square?

very helpful. Saved me from an insane asylum. #B3S
Thumbs up for the meow
As a CNC programmer/machinist I always get a kick out of watching people set their beds and offsets.
Thats not RobRob!! Thats Peter Jackson!
I really disliked this video, the only thing you shared was that you can fix the problem, not how to fix. This is just a false elder to get people to go to your website. Gosh, I'm mad at you for wasting my time.
Sorry you didnt like it. And yes- for technical things like long links to forums and file downloads and detailed photos and things, I will link to my ad free website that I run at my own expense , as it’s an easy way to collect and host those types of things. ¯\_(ツ)_/¯
Josef Prusa is a scam!
It makes an excellent advertisement for your product but the same your products are crap, they don't work as they should.
My husband and I bought an MK2S and upgraded to MMU2, until today the printer does not work properly.
We thought it was punctual and we bought a Prusa Mini the same problem (it doesn't work).
We got tired, we ended up buying a Weistek printer for a third of the price and it works great thanks.
Josef Prusa pays digital influencers to spread his brand and influence people to buy that piece of shit.
Make no mistake, PRUSA does not work well.
My Prusa Mini took a little tinkering out of the box- (which, i wasn't really expecting to have to do but it was easy enough) but once I dialied it in a little, it's been rock solid, at least with PLA. ( I haven't tried any other types of filament).
some people aren't meant to print.
