Thanks! With more not half bad 32 bit boards out there, is it worth it to spend extra $$ on a high end duet as opposed to, say a SKR E3 mini / octoprint bundle!?

Matthew Fochs

Have you ever thought about taking everything you have learned from the different printers you have reviewed and making one, custom printer that takes into account all the different things you liked? I know you said you have a lot of ideas for the SecKit, but I would love to watch a series of you going through each part of a printer and highlighting what you think is the best way to solve that particular system. At the end, it would be a full series explaining the different assemblies and would result in a custom printer that would ideally be your favorite.combination if features and reliability.

How are things going with the lowrider and the k40? What projects you have been working on with those machines ?

The new skr v1.4 is set up to accept a wifi board now. Idk how good it's wifi interface will be. I plan to find out soon

Geoffrey Pitman

Echoing a previous comment, a custom built printer from parts that can be purchased on ailexpress. So we can build/improve along with you.

Markom3D

What assisted you in growing such a large YouTube community?

Tyler Zlatkus

What is the most frustrating technology you encounter often that you have no control over? How could we fix those problems? and why, in your opinion has it not been optimized already?

John Parish

When should I just toss my existing 3d printer vs spending money to upgrade.?

Robert Mathew

When you review 3d printers can you include checking the PSU is properly grounded? The ender 3 and ender 5 plus have this issue.

GadgetAngel

Is it possible to install dual Z-Axis lead screws on Ender 3 and still use a timing belt to help keep the two Z-Axis motors in sync? If one should not use two motors then will two lead screws with timing belt give enough support across the X-Axis to install the E3D Hermera Direct Drive? If you should use two Z-Axis stepper motors should you wire the motors in series or parallel to the single Z-Axis Stepper Driver?

Noel Wade

What do you feel is the current state of multi-color 3d printing, as 2019 wraps up? Between the Palette2, Prusa MMU2, 2-into-1 filament systems for a single hot-end, color-mixing hot-ends, and multi-hot-end systems, there are so many options! But a lot of them seem finicky or only suited to a few printer models? What do you recommend right now for someone looking to get into printing in 2 colors at a reasonable price-point? What about 3 or 4 colors? Thanks for all the great content in 2019!

You might want to check the setup of the Anycubic Chiron. It got 2 independent driven steppers with 2 leadscrews for the Z axis with 2 independent homing so you can always be sure the gantry is in the same distance on both ends from the build plate

Marty Wise

Any tips for switching materials? I am new to this and am experimenting primarily with PLA and PETG. It took me a while to realize that, after printing PETG, small bits that might be left in the hot end were causing clogs when I switched to printing lower temp PLA. Is there a good process or procedure for clearing the old material before starting the new one? I'm not sure if I've ever gotten good results on my Ender 3 with a cold pull. The best I've been able to come up with so far is purging a bunch of the new material (PLA) through the hot end set to the higher temp of the PETG. Is this sound? Do I risk creating some kind of deposits of over-cooked PLA in the nozzle? What other options might there be? Thanks for all your help! Marty Wise Gloucester, Virginia, USA

Brandon Wolfe

Have you ever considered, or been approached, to collaborate on a project with any of the other prominent maker- you tubers (Ivan Miranda, Makers Muse, 3DPN, 3D Printing Nerd, Thomas Sanladerer, RCLifeOn, etc...)?

hernsl

Have you considered a linear rail conversion for any of your V-Slot & Wheel based printers? It can be expensive. Is it worth upgrading something like the sender 3 or better to get a top notch unit from scratch that doesn’t require all the mutilation.

kurtnelle

Do you think that the desktop FDM 3D printing market is saturated with product offerings or that is is room for additional vendors who offer can something different?

Mark Lopatka

Do you still consider 3D printing as a hobby, or has it become work? And how does your family feel about 3D printing? 3D printing does take a lot of time, and I am always walking that fine line of spending time building a printer, fixing a printer, upgrading a printer, and of course designing and printing vs helping my daughter with homework, taking her to volleyball games and practices, and being a husband! Much of my time spent with this great hobby is late at night. And of course the explanation of my latest AMEX bill! Do they get involved at all?

David Rolling

Your sources for pieces and parts. Everything from boards, stepper motors to tools, screws and bigger parts. I know you reference different sources for specific components you test, I’m more interested in “the rest of it”. Along those same lines what pieces do you purchase extra and how many do you minimize downtime on your workhorse printers? Current recommended tools for a starter. Lastly, hoping you have affiliate linked for everywhere you recommend.

RodneyChops

I have a stock Ender 3 board, Is there any point in upgrading to marlin 2.0 without a better board? I thought maybe there would be some new feature to take advantage of, because i think it still will work with 8-bit. Also keep up the great work!

Chris Bart

I would like to see you take your Marlin 2.0 coverage up a level. Not just: "Change this number to this setting," but teach us how to use the different modules in Marlin so we can take the main version and do it ourselves.

Joshua Theobald

I’d like to see some instructions on servo stepper motors along with the new SKR V1.4 board updates and their impact on ender 3 builds

BTT just emailed me to send me a V1.4 and I asked for the accessories too. Once I fit the Duet to the SecKit I'll have a good point of comparison. It would have to be amazing to justify how much expensive it is than the SKR series.

Teaching Tech
>>30454219

My method when changing back to PLA is to heat to the higher temp of the previous material and run a bunch of PLA through to purge. Still haven't used that cleaning filament but I'll have to at one stage.

Teaching Tech
>>30454512

Some of those bigger channels have contacted me from time to time. I had a few around the Endurance Laser fiasco offering support, which I greatly appreciated. No talk of collaborations from them. I haven't asked because I was always wary of appearing like I was trying to leverage them for views. Having said that there's a few people here I'd like to collaborate with in the future.

Teaching Tech
>>30455701

Videos coming for Ender 5 and Ender 3 (y axis only). Personally I agree it's pretty expensive and if you are dong just for print quality, it's probably not worth it unless you want to over engineer everything.

Teaching Tech
>>30459282

If I was in the states, I would be using Amazon, but it's not really a thing over here. I use Banggood and Aliexpress time to time, but mainly local ebay. As for tools, I'm more likely to pick them up in person locally from hardware stores, etc. I'm launching a website soon and can make a tools list on what types of things I use a lot with links.

Teaching Tech

Should have a V1.4 on the way shortly and a company emailed me recently about servos like that. Watch this space.

Robert Mathew
>>30452478

I discovered this from th3d where people were getting false positives on the bl touch. I personally do not trust non branded psu's... However if people will use them they should at least verify it is properly grounded... If it isn't grounded properly at least they can be informed on how to fix or replace it. https://www.youtube.com/watch?v=rxqT2AjI8Fw

Robert Mathew

Thoughts on a tutorial for esp8266 or esp32's?

Robert Mathew

Any luck getting an antijam sensor to work for filament? Only option I am aware is the Duet3D Filament Monitor

Robert Mathew

Thoughts on creating a video were your viewers submit problems they are having and common fixes or suggestions? Viewers can either submit screenshots or videos of the problems they are having.

Teaching Tech
>>30486345

Do you mean a sensor that tracks filament movement, instead of just whether it's present or not? BIQU Thunder has a rubber encoder wheel but no hints on firmware implementation for this.

Teaching Tech
>>30486381

It's an interesting idea, my only concern is whether things could be answered on the spot or not.

Chris Bart
>>30473537

I have not found any writeup with exactly my combination (Ender 3, SKR mini V1.2, BLTouch, sensorless homing, 512k hack, etc.,) and would like to generate a configuration of Marlin 2.0 that will apply. I could go through every video out there, and write down the instructions for each adjustment, but I still wouldn't know what I was doing. I would like to go a step further and actually understand what each change I am making does. Of course, for you to explain it 100% might be harder than creating the software in the first place! I just want to know enough to understand what some of these adjustments are doing. You've gotten close to that, but a bit more explanation rather than simply change parameter x to setting y would be nice.

Noah

Sorry I know it's late but I wanted to ask you about remote direct drives like zesty nimble or flex3drive for an ender 3. Do you recommend it, is it difficult to setup and configure. Is it much better then mounting the motor above the hot Ender?

Teaching Tech
>>30571107

On paper those extruders are the best of both worlds. You get the lightweight of a Bowden setup but the easy to tune extrusion and tiny retraction of direct drive. I'm keen to test them out. If the heat sink on the hit end is working the placement on top of the hot end heater shouldn't matter.

Jeff Weiss

I just got a CR10 V2 and I really like it. Eventually I intend to build an enclosure for it. I am going to try and upgrade the motherboard to the new V1.4 tomorrow. I have some tmc2209's and I think I have the firmware figured out. A video on upgrading the CR10 V2 would be nice as well. I know I'm late but why not ask. I got the creality enclosure for my Ender 3.0 Pro and it works fantastic. I bet you could make a heater for it easily.

Randall Harshman

Any thoughs about the Ender 5 Plus? I love the size and stability of it but not sure of its abilities/

Darren Sherriff

Hi wondering if you are going to look at the SKR 1.4 turbo in the near future?

Steve Plowman

Hi, as mentioned elsewhere I am having a frustrating time downloading files to print even from your you tube clips. Could you possibly do a short tutorial on basic requirements to achieve some success? Cheers

Teaching Tech
>>30473537

I can do a video like that but it would be half an hour long. Maybe something to consider as a Patreon exclusive?

Jody Cochran

Hi Michael, I am really enjoying your videos. I purchased the skr mini e3 for my Ender 3 and have printed a few things with it so far. I am noticing some issues like the motors get very hot, more than they did with the stock board. Is this common for these stepper drivers?

Jody Cochran
>>30700410

Thank you for your response. I think I figured out why they are overheating. When uploading gcode to print, it doesn't seem to respect the build size every time. I have printed a 20mm calibration cube and it measures accurate, but I just tried a few other models and they are scaled in the X or Y direction, so the motors try to turn past the max bed limit and click angrily. Do you have any suggestions on what I need to adjust to get that working properly? 

Roberto D'Isanto

Hi Michele, have you ever thought about making a video on marlin's UBL? Maybe testing if it's really useful? I activated it on an ender 3 pro with skr 1.3 and a deformed mat, and actually improved the first layer. Congratulations on your work and happy new year!

Teaching Tech
>>30810396

Hi Roberto, I don't have much experience with it. It seems quite complicated compared to what we usually use. I am intrigued to learn more.

Mel Ober

Hi Michael, First off love your channel. It's been invaluable getting me my 3D printing adventure off the ground. Previous to finding you on YouTube I had been struggling off and on for the last 6 months to produce any usable printed items. Long list of failures. I'm very new to 3D printing but am extremely fast learner and fearless when it comes to DIY projects. I currently own an Ender 3 with updated firmware Marlin 1.1.9, Creality tempered glass build plate, upgraded cooling with Ptesfang Bullseye. My planned upgrades are BIGTREETECH SKR Mini E3 V1.2 mother board, Filament runout sensor, BLTouch auto bed leveling and eventually Octoprint. I was wondering if you have a video or just some info on installing the the runout sensor with the BLTouch using the BIGTREETECH SKR Mini E3 V1.2 motherboard. As always love what your doing and am glad to be able to support you doing more of it.

Teaching Tech
>>30985327

Hi Mel, I actually went and updated the V1.2 video a while after it came out. There is free firmware with BLtouch and filament runout enabled, plus the diagrams for where to plug in each of these are liked and timestamped in the description: https://youtu.be/ikHhzOIlHPg Thanks for your support and well done on gaining traction on your 3D printing journey.

Mel Ober

You Rock. Thanks for making my life so much easier.

Roberto D'Isanto
>>30810396

Great! If you need any information contact me. Marlin's documentation is not very clear at this point. A little tip: even if you use the marlin menu on the printer look at the serial with pronterface or octoprint, some information comes out only there, for example the points that cannot be reached by the probe in the first phase.

Happy New Year Micheal:

I have tried to change the x stepper motor on my ender 5 with the (17hs4401). But it is very noisy, and is choppy. Is it not suitable for the ender 5 or is there an adjustment in the firmware? You're doing a wonderful job and I hope that 2020 is the best year with the greatest success.

Teaching Tech
>>31038746

Some times the wiring needs to be tweaked with stepper motor changes, but in these cases no rotation can take place at all, it will just noisily stutter back and forth. If yours is moving but jerky, my other suggestion is playing with Vrefs. A bigger stepper will require more current and a higher VREF.

Geoffrey Pitman
>>30453512

As a basement price just to try it out, look at the Geeetech A10M or A10T. They are the same frame with either a 2 or 3 material mixing extruder respectively. Be prepared to do a lot of tinkering though.

Earl Houseknecht

Hello Michael, I've been following your channel for just over a year and found many good tips on how to properly use my A10M 3d printer. I noticed in the video today that you also have an a10M and wondered if you have ever encountered a blockage in one side while the other works just fine? If so, how can I clear it? There seems to be a build up of melted PLA that keeps me from removing the hot end.

Teaching Tech
>>31605414

I haven't experienced that but my advice would be to heat it up as hot as firmware will let you with the bowden tubes removed and then use a 1.5mm allen key or similar to try and push bits through.

Eric Kohlmann

Hello Michael, I just followed your BLTouch V3 w/ fixes videos to install a BLTouch V3 kit from Creality. I added the G29 as instructed, but it doesn't appear to probe the bed as I'd expect before printing. It simply homes once in the middle and then starts printing. I am using your custom firmware for the V3, do I need to edit that to make sure it homes and levels before starting to print? Also, are you planning on making a video on making the bed solid, or do you keep the adjustment wheels and springs? .

Teaching Tech
>>31686670

Hi Eric, I would connect via USB with pronterface and send a G28 and then a G29. It will say unknown command if anything is wrong with the firmware setup. Assuming that works then inspect your gcode file with a text editor and make sure there are no typos around the G29. If you want to remove springs, it's a simple swap out to solid spacers, the BLtouch should mean everything is automatically compensated for.
