The part with you showing and explaining, that flaws in the FDM process are most often just hidden (either on purpose or by accident) is the most important one imho, because I feel most experts/brands/YT channels don't like or want to say it that frankly.

Man you make some the best quality 3d printer videos on YouTube. Keep up the great work!

[JoshuaJayG]

Well done. I have a kid next door asking about settings on his new printer, I've been pointing him to your videos (great timing), and Teaching Tech's videos.

You changed my 3D printing life a couple of videos ago! 1mm on first layer solved all the problems I had with bed adhesion. And 1mm on all layers work great for many of my models, and cut the print speed in half or more. Thanks Tom!!

Man you are really revolutionizing 3D printing for those new into 3d printing. I remember that I was struggling wit 3d printing 2 years ago, and your videos alongside with Maker's Muse made it so much of a more enjoyable process for me.

[electronron]

It's nice to see everything coming together in one place. When I got started I had to watch videos by people like yourself, Chuck, Joel and Angus.

[DeputatKaktus]

Your videos have been such a great help on my 3D printing journey.
Having jumped straight into the deep end with the notorious A8 (and the subsequent called the AM8) your insights and tips have saved me in my hours of despair when nothing seemed to work and the machine was close to a spontaneous defenestration. I still keep coming back to them years later when I am stuck somewhere.

Thank you for making these videos and putting on all this effort.

There can never be enough of these print guides especially to just keep up with how quickly 3D printers change. I still remember the days threaded rods were acceptable for printer frames haa

I really appreciated this series you made; it was what convinced me at the end of 2020 to buy my first printer (ender3 pro). I've had it running nearly 24/7 since; have done extensive upgrades. Early on I experienced intermittent underextrusion that took a while to diagnose; eventually I discovered the cracked idler arm on the extruder (that's a really outdated extruder design). I also had intermittent layer shifting issues which I ascribe to improperly tensioned belts or possibly excessive stepper driver current. Both were great learning experiences, if frustrating in the moment.

I have been very interested in the voron project and appreciated yours&cnckitchen's reviews. I plan to build a voron 2.4 300^3 or 350^3, super hyped for parts to arrive on the slow boat. I will continue to follow your vids, and thank you for your commitment to and emphasis on open source in the printing community.

Great stuff. I got my Prusa MK3S kit in April and after putting it together, I have been printing like crazy. Your videos (and the Prusa forum) have helped me understand a lot of the settings and troubleshoot. Thanks again and keep up the great work!!

[turkoharley]

You rock I made my first printer looking your videos. exactly one year ago. Now I go for the second. Thank you very much.

[leunamtzam]

Espacialy the samples you show like at 8:40 are very usefull for beginners. Thanks for this good video!

This series is better than any paid courses on Udemy teaching the basics about 3D printing.

6:00 Something to add is a damaged heat break. I couldn't figure out for the life of me why my printer refused to print. Tried quite a few cold pulls including one where I nearly punched myself in the face when it released. (LOL) I took my E3D hotend apart to see where the hangup was and noticed the heat break was bent slighty. Replaced it and it worked much better. Also get a bondtech extruder, the one that came with my mendelmax 2.0 was crap.

From the title I was envisioning pictures of when you get back to your over night multi-hour print and discovering it failed spectacularly, either it printed a birds nest since it stopped adhering to the print (like when a tall object falls over during print) or a huge blob of material stuck to the hot end.

Ey Tom is back again with a basics video. I love it!

I have two questions, these questions are not really widely discussed so that is why i am asking.

Questions:
- How does a belt rubbing on one of it's sides effect the print quality?
- How do I minimize overshooting corners without linear advance.

[vampcaff]

i had crazy layer shift on my cr10s pro and all it ended up being was a loose stepper driver pinion gear. love this video series by the way!

[jawaulk]

Oh while complaining about YouTube, I forgot to say thanks Tom great video.

[JT-reec]

I wish I could get a personal instruction session from you, thank you for your videos!

[candyblow]

damn... I watched all the previous episodes just to find out that 3D printing is not user-friendly at all. hahah Thanks for sharing all the great tips and knowledge Thomas.
