@techsaladHi Brent, will your website get updates soon?

@阿诺德嗨，阿诺德，我想只是张贴所有的mods和方法，使这台负担得起的打印机从悬臂打印机疯狂的准确性。而且打印速度的提高是疯狂的！

I suppose I must provide a little background to understand the snails-pace this project is suffering from…

Fourteen years ago a car accident completely changed my life and many doctors said I would never work again. But as we humans do, we survive, adapt, and if a passion is strong enough… we sometimes overcome our disabilities for a few hours a day. My days are broken-up into three or four 1.5 hour sessions of being vertical, the rest of my conscious time is horizontal meditating to lessen the effects of extensive soft-tissue damage the length of my spine. Some days I’m blessed to enjoy a little more time to think past the pain, but those days are rare.

This mod project started out with a robust z-axis stiffener, it had to be bolt-on and easy to install. My z-axis is solid, the weakest link now is the stainless steel base everything attaches to, but I also have a solution for that problem. The z-axis mod definitely improved the print quality, but not enough to satisfy me.

My attention focused on the y-axis structure. Four more mods were created, and the print quality improved and higher print-speeds attainable. But again, I was not completely happy. I already knew the extruder motor ran too-hot and being a two-phase stepper it had to rotate far more than a four-phase to achieve the same move. I thought I should publish my findings to this point to help others with their printer woes, started to organize the mods and document methods/procedures but the pain quickly invaded… not enough distraction from the pain. Focusing on the extruder setup got me back into the zone of less pain, so I dealt with the axial torque and the overheating extruder motor. Rock-solid motor mount, waaaay less heat and more torque… excellent. Even higher print-speeds, this is where I broke through the 90mm/sec limit, printing faster with very little loss of quality-of-print. The surface artifacts had decreased substantially at this point, but yeah…still felt there was more I could tackle and solve.

在这个项目中，我花了大量的时间为这台潜力巨大的小打印机设计/工程解决方案，却忘记了作为一个渴望更好生活质量的残疾人，我的经济稳定所付出的代价。这个项目让我少了很多痛苦…我对产品开发和原型设计上瘾了。所以，你可以想象，这里什么也做不了！

我偶然发现下一个国防部extr内uder setup, but wow… I mean double-wow …the quality-of-print is what you see above in the photos I posted. Am I happy yet?? …I’m frickin’ bouncin’-off-the-walls happy!! Maybe I can hire a housekeeper happy!

So here we are, I have a bunch of mods that make this printer sing, and dread the next step because this process of publishing is going to take away the distractions that allow me moments-of-freedom from the pain.

Is there more to create/engineer and solve… yes, the heat-zone is too long, I’d like at least 12mm’s of sequential printing, a reliable automatic bed leveler, an electronics hat that does not trap heat, reliable flexible filament printing, an alignment jig for x/y/z…etc etc … I have many on the list! Do I already have solutions… yes. Do I have freedom from the box-of-pain… only when I’m in the engineering and/or creation mode.

没多久我就发布了mod包，我已经停止了其他mod的开发。我正在尽可能快地清理原型并准备一些文档。

cheers,
布伦特

Hi Brent, thanks for sharing a bit of your background! Your prints look really amazing and I’m very looking forward to see how you achieved all of this! I did some minor mods and improvements on my Cetus MK3 setup, but mostly peripheral ones. I can totally relate how designing/prototyping pulls you in a zone and happy that it helps you push your pain in the background for a bit! All the best to you in the meantime!

PS: Can you add a link to your website in your profile? I have trouble finding it…

@超人, profile is updated… I was trying to avoid any attention to the website, it’s extremely basic and not interactive as yet.

Tks for taking the time to understand why this project has been so slooooow to publish, wish I could wave-my-hand andpoof…done …and many folks unleashing the full-potential of this little printer.

I have another printed model pic to share…yesterday I mounted a .2mm nozzle which I hadn’t used since purchasing the printer last year and not since sparking-up Simplify3D. The printer’s firmware is compensating for something…after calibrating z, and loading a gcode file from S3D, UpStudio was printing in air at .10LHeight. Normally, I print without any software tricks, rafts, supports etc etc… just a brim on an optical mirror with green painter’s tape and the extra length of the green painter’s tape is sandwiching the mirror to the stock build-plate with 20+ brass shims in-between. After offsetting z by .10mm …still printing in air, lacking the time investigate I printed at .15LHeight and .25LWidth…just barely tho. I’ll post the pic soon, need a flat-black background to show-off the crisp edges.

cheers,
布伦特

@techsaladThanks! Will keep an eye on your page and any posts here in the forum!:slight_smile:

First few prints failed as mentioned in above post and having very little experience using a .20mmNozzle 10mmLayerHeight .25LineWidth, my build-platform leveling strategy required a more aggressive procedure.

取下绿色颜料胶带，在UPStudio中用一张0.04毫米的纸从我的工程师袖珍参考中校准…哎呀…但是不用担心，用的是万年历上的一页:wink:. 每个校准点的设置…纸张几乎不能移动而不会撕裂。

重新涂上绿色颜料，用胶带和抹刀轻轻抚平山峰和山谷。

使用0.02mm黄铜垫片重新进行9点校准，并在每个校准点进行设置…如果垫片没有撕裂和凹陷，则无法移动垫片。使用垫片确定的准确高度确认校准程序。无偏移或从精确高度上加/减，此喷嘴高度用于S3D和UPStudio。将一个伪stl文件加载到UPStudio中，然后右键单击以删除所有模型。重新启动UPStudio并执行挤出循环，以检查灯丝和喷嘴加热区中的水分。很好…

Next post will show the print result, please keep-in-mind I do not care about bridging fails, small artifacts resulting from layer-changes or any other surface-quality fails controlled by tweaking print-profiles in software/firmware. For me, and the scope of this project, the measure of pass/fail is determining if the hardware mods I’ve created are providing the hardware backbone of the 3D print-process allowing for extreme accuracy and higher print-speeds in excess of 100mm/sec.

Cheers,

@techsalad，你的故事很精彩。在另一个论坛里，我们还有一个残疾人，他喜欢3D打印。

@阿诺德, the person you’re referring to …did he/she have an accident and the printer toppled onto the floor creating extensive damage?

@techsalad, well we talked about our eyes:grinning:他有一只眼睛是瞎的，所以我的左腿还是比较好的。

几天不好过，抱歉耽误了各位…

So, after the aggressive build-plate leveling procedure mentioned above, I wanted to see how accurate this modded MKII could print at .05mmLHeight x .25LWidth using the stock .20Noz.

启动了S3D并加载了SyntaxGeek的.20Noz S3D配置文件（Thingiverse-3035906），这是@antoledcetusamazing S3D profile also available from Thingiverse. Huge shout-out to@antoledcetusfor his S3D .40Noz profile, I used his profile to print the models shown above in an earlier post.

Loaded Thingiverse-2039065 (this is the coupler and nut as shown in an earlier-post above printed .40Noz .20LHeight .40LWidth 65mm/sec). Attempted .05mmLHeight x .25LWidth using the stock .20Noz. No-go, too many settings to dial-in .05LHeight on the .20Noz, It’s the extruder flow-rate that needs tweaking, just don’t have the time to investigate.

这是一个以40毫米/秒的速度打印的0.20Noz，高0.10l，宽0.25l的耦合器。
no supports, no raft, no brim…just those 3 tiny pillars you see at the top of the coin.

Tks for the feedback@比约恩, difficult to show the profile while keeping overall focus but also trying to display the layer lines. A shallow depth-of-field while in macro mode because of the taper, need a 3D camera to properly photograph this type of subject:wink:

Thought it might be fun for you folks to see a portion of my CAD workstation for the Cetus3D mod project. To the right are two 24" CAD monitors, a 21" Wacom Cintiq Artist Tablet and many more tools-of-the-trade.

There is a slight teaser of my heavily modded Cetus3D MKII in the photo …enjoy:sunglasses:

Thanks Brent for the updates, the 0.2 mm prints look magnificent! Still very looking forward to your mods, but no pressure, just Vorfreude!:slight_smile:

I received the heated bed upgrade parts for my Cetus MK3 today, so some fun stuff to tinker with in the coming days.

@超人，谢谢你的反馈。我也是佛洛伊德！

You know Andreas, I’m a little puzzled these days. A few months ago, when I was in frequent contact with a few of the support staff at Tiertime regarding the mods I was developing, I mentioned I had found a way to further stabilize the y-axis with two bolts. They could implement the method at the factory and no-one would ever notice the mod was in place. You would have to know it was there to discover it, seriously, it just blends into the existing hardware and looks like it’s just another bolt-head performing the fastening-job the others are. I offered the mod as a trade-secret and said I would sign an NDA to complete the trade-secret circle-of-knowledge…no reply to-date.

我已经参与3D打印行业7年多了，我继续惊讶于精密部件的持续使用，这些部件附着在不那么精确的结构部件上。我知道，在市场上竞争是一种平衡……金钱使世界转向……资本主义vs产品进化……剃刀的边缘。

编辑：享受新的加热床升级，我可以看到你的perma笑在你的论坛帖子！

Anyway, back to work…cheers, Brent

@techsalad是的很困惑当人们喜欢你,who have a lot of experience in the field, happily contribute to a better product and it’s not even considered… And sure, it’s always a trade-off, but if a few printed pieces or other cheap parts can make a significant difference, you have to wonder…

我从2019年初开始进入3D打印领域，到目前为止，我真的对这个社区感到惊讶。很热情，分享很多，很容易贡献。BOBapp体育下载

Still in the process of installing the heated bed. Although I’m puzzled by two printed parts that where included… No documentation/manual available, oh well.

@techsaladCheers! I commented here with photos:https://support.tiertime.com/hc/en-us/articles/360023111253?page=1#comment_360002149073主要问题是更换支架（如果必须使用的话）。它有一个凹痕，看起来有意的，可能提高了支架的结构稳定性，但使它不可能安装平坦，不成角度。考虑在支架和轴承座之间设计一个垫片，以便均匀牢固地安装。印刷部分是另一个难题，但我想没有那么重要。我以为那个有洞的可能是个间隔棒，但不适合这个用途…

Thanks for the words guys, really makes a difference for me hearing them… most certainly propels me to continue despite my physical burdens. Cheers, seriously!
