@techsaladAwesome thanks for the update.

@斯凯佐终于早上收到了机器店的电话。他们将在周末加班,并在9月22日星期日前往我的价格报价。

With any product in it’s early stages, the question arises, how many to produce? To-date, there has been little indication of demand for this mod-package. To be honest, until you@斯凯佐expressed interest, I had moved-on to other projects…there has been only one other Cetus owner having expressed interest.

我非常高兴我的Cetus打印机与修改,我已经作出了提高打印质量和享受疯狂的速度,我能够实现打印原型和概念验证时,很少损失质量。基本上,它煮沸了…我有一个小脚印(真正的桌面)3D打印机,打印像冠军。每一个印刷品都和上一个一样,没有斑点,没有表面瑕疵,没有细线,没有喷嘴堵塞,每一层都是正确的…我还在使用库存电子产品和库存喷嘴…哈哈。尽管我有一个额外的Azteeg X5,更好的步进器,一个测试版的第一代Bondtech挤出机组件,安装这些东西有什么意义??。好吧,我最终会升级电子设备和挤出机组件是有原因的…但这些原因并不是基于打印质量!如果我还在运行一个3D集线器打印服务(2013年,加拿大西部只有8个集线器),我会购买50台这样的打印机,安装我的mods,在竞争中转转……我会比那些2500美元以上的3D FDM打印机更快地提供更好质量的3D打印。与此同时,我有一台3500美元的SLA打印机闲置着收集灰尘…为什么…后期处理…真的很简单…见鬼,我可以在Cetus上打印,用我的手指拧下床上的打印,然后使用打印模型。嗯,不是所有的印刷品都可以使用,我有时不得不从印刷品完成的地方剪下细丝……很少有印刷品焊接到玻璃印刷床上的绿色油漆胶带上。

Ok, enough rambling,@斯凯佐,原来我是想说……如果there are only two Cetus owners interested, and I order two sets of mods to be machined, the cost from the machine shop will be too expensive. We’ll see what the machine-shop quote is this weekend. I may have to machine the parts myself, not something I’m looking forward to, it’s incredibly repetitious and it’s boring work. It’s the “boring work” part that gets in my way… as I suffer extreme pain daily and “boring work” is too little to distract from the pain and mistakes are easily introduced.

所以你有它......完全透明度......那就是这些模式当前存在的地方。

干杯,
布伦特

The weekend came and went, no quotes arrived. It seems the normal these days is cherry-picking potential orders for the greatest revenue, and those that don’t hit the top 10 stay at the bottom of the list until there’s a lull in the incoming projects, not to be confused with… a temporary lack of manpower to meet the demand. The other thing I see happening is long-time customers automatically slotted into the top-ten projects to concentrate on, this is one of those areas where capitalism kinda fails, especially when attempting to support local business. Well, this is strike three, and that’s one too many for me… so it’s time to cut the tether-of- forgiveness and move on. Sorry for the delay@斯凯佐,让我知道这是我的第三次罢工,你已经失去了兴趣。

此致,
布伦特

@techsalad不用担心,谢谢你望着它。您是否可以开放,以便在GitHub上开放您的工作?这样,人们就可以使用他们的本地机器商店获取创建的mods。

@斯凯佐, I have considered the many ways of making the mods available to folks. Even though the machining processes required to make these mods might look inexpensive to produce, there are a couple of features requiring less than .001" (.03mm) tolerance. When a tolerance dips below .001" the machining cost increases. The angle of the longer bar must have a very low tolerance otherwise it will not comfortably fit in the very-narrow safe-zone where it is close to the print-bed and the z-axis stepper motor. And then there is also the face of the aluminum bars that meet the extrusions, they are milled flat, also requiring a low tolerance over the lengths. The other thing going on is… these extrusions, by design from all the manufacturers, are not flat over the widths of the extrusions. When I hold a Certified-Flat Laboratory-Grade bar across the widths of the extrusions, they are not flat-and-square, some areas might be but not all areas. I was as surprised as you might be. This is no fault of Tiertime, the extrusion quality used by all the printer manufacturers are low to keep the costs lower. So I will likely have to include brass shims.

短答案是,从您当地的机器店,制作一套的成本很容易是100美元+。If you don’t care about dimensionally accurate prints, and only want to get rid of the z-axis wobble on tall prints, then I guess you could relax the tolerances and get the cost below $100, but it won’t be by much. Their setup fee will be $40+ …probably closer to the standard $65.

我希望得到三个铝稳定杆的销售价格远低于100美元,接近50美元大关,如果可能的话。如果我们得到50个Cetus用户承诺,那么我们可能在70美元左右的大关,100套将接近50-60美元大关。

如果我可以这么大胆地说......好的,我会...
These stabilizer mods are awesome, not because I’m biased, they really do the job… all the way…very little room for improvement if at all. There is no other way to有效应用completely螺栓上(外骨骼型)溶液,其与最小金属材料和零干扰为主inexpensively就像这个mod包提供的那样。我知道,这肯定是个艰巨的任务。

我在Cetus打印机上安装了11个Mod,他们都一起工作。每当我打印东西时,我都必须说我只是惊讶于质量......从1000美元的打印机!......和一个悬臂式!,不是最受欢迎的3D打印机。

如果人们只做一件事......只有一个mod ...稳定喷嘴......你的打印精度将增加一个very大量...保证。该MOD与稳定Z轴相结合将使您微笑。

干杯,
布伦特

Just finished building a storage/dispensing box for 6 reels of filament. To reduce the friction of the filament delivery I designed a ball-swivel that attaches to the box minimizing the friction as the filament moves from the moisture controlled environment through to the extruder. As the amount of filament on a reel declines, the friction through whatever you use to deliver the filament to the extruder increases…and by a fair amount I might add. When the amount of filament on the reel gets to less than 50%, the amount of friction within a moisture proof delivery system triples… more depending on the type of filament.

I found a manufacturer of PTFE tubing that reduces those amounts of friction. It’s the Capricorn XS brand. They have a 4mmOD x 1.90mmID PTFE tubing… I highly recommend the Capricorn XS tubing, it’s pure PTFE and is very slippery. The 1.90mmID versus 2.00mmID also reduces friction by some amount, especially flexible filament. The XS type is rated at 340deg Celsius. They also have the XS type in 3.00mmOD x 2.00mmID, this is the size in the upper neck of your nozzle. I believe the tubing that comes with a standard nozzle is only rated to 200deg Celsius, so if you are printing at above 200deg Celsius, then the tubing is degrading at an advanced rate and over-time will contaminate the filament as the tubing burns, so frequent cleaning is required, by removing the tubing and wiping clean the black grunge of burnt filament and burnt tubing. The other thing happening before the burning is deformation, so it will no longer line-up with the surface of the lower brass part of the nozzle as engineered by Tiertime. There is very little room for error here, if the nozzle ptfe tubing is not perfectly square at the bottom end, there will be filament delivery issues. If the nozzle tubing is too long it will flare and choke the filament creating filament delivery issues. The problems created when using a standard PTFE tubing above the rated 200deg Celsius are numerous…basically most of the problems reported by Cetus owners when filament is not delivered to the print-bed as expected.

好的,用今天的ramblings完成......像往常一样......假设位置......快乐的打印是!

@斯凯佐,看起来我将在我的数控铣床上加工第一对。我不适合加工零件的生产运行,我是一个想法原型和产品开发人员…所以主要是加工零件之一。

This first production run of the z-axis stabilizer mod will be priced at $65.00USD to get the ball rolling. I’ll machine 5 sets this time. This initial price will include stainless-steel fasteners, lockwashers and shims. This first production-run price will change if there is a second batch produced at a machine-shop.

今天早上,我与我在我的Cetus打印机上使用的Mods遇到了2个机器商店,并要求球场的成本。当生产每批25套的数量时,他们的口头成本(不保证)估计大约为80.00美元。这种球场的成本仅适用于加工,不包括任何后处理,如漂亮的表面饰面。

如果其他Cetus用户感兴趣,请尽快告诉我,因为如果机器车间生产的批量少于每批25台,价格可能会更高。

@斯凯佐,请告诉我,如果您想订购一套,我们可以通过私信设置付款。

干杯,
布伦特

@斯凯佐, There is a way to reduce the cost for folks wanting to have a local machine-shop in their area produce the parts for the z-axis stabilizer mod I’ve designed.

我所考虑的想法将大大减少设置费用(45美元 - $ 65usd),所有机器商店都建立在整体成本中。

这个想法将涉及伙计们的一点工作,让铝棒能够在没有太多设置的情况下只需进行机器店就可以执行加工操作,有效地减少了巨大的设置充电。

I’m thinking of creating a thin sheet-metal template etched and cut with a laser. The drilling locations would have a tiny laser-cut hole where folks could simply center-punch the location, near the hole would be laser-etched dimensions and specific instructions.

The template would be cut to the size the aluminum bar needs to be with any angles included, near the angle would be laser-etched instructions. To reduce the material costs(shops usually profit by providing the materials), folks could take the templates to a local metal supplier to have the aluminum-bar lengths precision-cut.

另一个有效降低成本的方法是从我的商店发货。

Any thoughts?

Is this still an active project? I would be interested in buying this if it fits the MK3 standard.

@难以置信J1, sorry for the late response. I’ve been battling with a sophisticated attack on my business server. An incredulous story for sure… the attack completely crippled my online business activities, long story short… we caught the hacker…a tenant in the apartment building…my neighbor!

是的,这个项目是重新激活,现在我已经重新控制我的业务服务。

It is my understanding the structural backbone of the MK3 has not changed from the MK1/MK2.

你有兴趣购买金属板模板或成品准备螺栓上稳定模式?

嗨,布伦特!
我今天偶然发现了你的mods!我想买你的改装套件为我的MK3准备!
令人敬畏的工作!

@ dar303,谢谢关心!我经历了一些挫折,使国防部工具包准备出售。看来到1月30日会有一些装备准备好。我给你准备好装备后会联系你的。

干杯,

@techsalad

Any luck on those kits?

嗨,伙计们,

I increased the first batch quantity twice last week and again yesterday. The quantity was based on those that strongly confirmed they would like a kit.

@斯凯佐我感觉到你失去了兴趣,因为我没有收到你的回复。我目前有4个额外的套件可用于第一批。如果你在他们离开之前让我知道,我会把你的名字放在一个。

@难以置信J1你仍然有兴趣加入mod kit吗?

第一批将在下周内准备就绪。

此致,

@techsalad

是的,我仍然感兴趣。

Thank-you for the confirmation@斯凯佐,你肯定是第一批!

也谢谢你的耐心,这是痛苦的缓慢,以使这个模块套件为人民准备。我曾希望有一个机械车间制造稳定器零件,因为我遭受了严重的车祸疼痛,没有多少好的时间在一天的机器零件自己。如果需求变得难以控制,我将不得不与一家机械制造厂签订合同来生产零件,成本很可能会翻倍。

干杯,
布伦特

Hi,

Sorry for the late reply. I’m just curious about the price and was wondering if it will work on a MK3 with the extension board installed

Hi@难以置信J1,我正试图保持尽可能低的成本。典型的机器商店超过100美元。我几乎完成了加工18套,思考价格将在65美元的标记附近。如果人们想用自己的紧固件,锁模,乳头垫片和TNUTS,价格将低8-10美元。扩展板很容易位于稳定器MOD或Z轴挤出上。

我将设计一个可打印挂载重新定位扩展板,我想了许多不同的解决方案。与z轴稳定器mod的性能升级相比,我认为扩展板的重新定位是一个小小的不便。

干杯,
布伦特

布伦特I just wanted to say thanks for the heater block bolts tip. My bolts were not loose but also not very rigid and I could see some artifacts.

担心过紧和剥离加热器块线程,我弯曲了1毫米不锈钢丝衣架。它绕着冷端的顶部缺口循环,而另一个金属丝端固定在挤出机印刷的驱动齿轮总成上,现在印刷在ABS中。我修理了我原来的MK2挤出机。

另一个简单的模式是移动挤出机印刷带附件的一部分,以顶部的皮带。我镜像了Cetus STL文件并用ABS打印出来。你需要反转一个步进阶段的极性,使软件高兴。动机是,我建立了一个加热超基地玻璃床,发现原来的Cetus PLA部分变得非常柔软,当使用ABS床印刷温度,我的设置是115至150摄氏度。我相信所有的Cetus印刷运动部件需要印刷出来的聚碳酸酯,聚乙烯亚胺或加工出来的金属,如果印刷在一个加热的建设表面。

@彼得101, tks for the comments and the tip about the belt attachment, I believe that attachment should be a thin stainless-steel part…your solution works for sure tho!

Even though you have comfortably tightened the heater block bolts the problem still exists. The bolts inside those stainless steel tubes are too small for the forces being applied and the threads will easily strip and become damaged. I installed a larger bolt size, but even a larger bolt size only gets you part-way to a rigid filament extrusion system. If you browse earlier posts in this thread you will find a picture of my modified extrusion delivery system. I added an aluminum post that anchors the nozzle…this aluminum post solves soooo many problems and allows the extrusion-motor to do its job precisely. If the nozzle is rigid then retraction works properly…precisely… and exactly when retraction is needed.

如果在整个打印过程中喷嘴高度刚性刚性,则您将不再能够与打印的部分的先前印刷区域/层进行喷嘴碰撞。虽然,如果z轴不是刚性,则喷嘴高度将在整个打印作业中波动,我保证你会惊讶于多少!

刚性喷嘴高度解决了许多其他问题,此时太多了。我一直在努力与一些痛苦的爆发,让我免于在我的商店里,并获得耐心等待的人们为那些稳定的模式。

我要你到我店彼得,你可以see the mods and the quality of prints they allow!

干杯,
布伦特
