The vast majority of noise you'll experience from Spindle motors is when the bit is carving deep into your stock. Compared to a palm router, Spindles are virtually quiet. A low hum for the most part. Comparing Air- vs Water-cooled is another, question. Both are extremely quiet but Water-cooled does have the advantage. Ex: 3d carving with a tapered ball-nose bit... you can turn off your extractor as very little chips are being produced. Water-cooled motors will be virtually quiet. The most noise you'll hear would be from the coolant pump.

1) I'm not sure if you know what 25 cubic mm means. It's a volume. If it is a perfect cube then it would be 2.9mm on a side. Is that what you were trying to say? I'm not sure what you mean.

You may also try printing model aircraft wing parts with "added" profile settings. Some sellers give parts of model for free to test how their products looks after printing.

Did you download and try the burtoogle version? That will solve all your problems. I feel like I'm talking but you're not listening. Sorry - it's a little frustrating when I get the same question 10 times and 9 people try my answer and are like "that's amazing" and then the tenth person seems to ignore me.

How to build a thin partitionwall

I have tried to print single wall with CURA for a while now. I have managed to get some results but using the surface mode and designing parts using Fusion 360 surface mode as I have failed to get CURA to print my 0.4 mm walls with a single pass.

You pay more but you get more. All the details have been figured out to install on my onefinity. Very nice upgrade for my machine.

5) What you show in the first photo - Cura can't do that - the way it thinks about inside and outside - it just can't do that. Sorry. People (including me) have been asking for that for about 6 years now. Programmers say it's not going to happen. Some day it will happen but don't hold your breath. Actually there is a mode called "vase mode" that can do what you show in the first photo - but the way you do that is a hack. You first give cura A *solid* model with the inside filled in solid. Than choose vase mode and it will just do one pass around the outer wall just like you want. You have to set the line width to how thick you want the walls and even if you have a 0.4mm nozzle you can do 0.8mm walls if that's what you tell cura to do but cura will do it in one pass.

Using the default setting for my printer (UM2E+) and used fine profile (0.1 mm line height) and changed "Line width" to 0.5 mm. Checked the "Saved" gcode file in Cura Arachne Beta and found no issues, then opened the same file in S3D and the object was superb. (This is the best "water test" I can do to be reasonably sure that this print will "shine".)

I printed a 25 mm³ cube and found that my printer is spot on. But in the X and Y axis, that 25 mm prints at exactly 25.4 mm.

Thanks, geert_2. But the issue is visible in the slicer. As for the version gr5 was referring to, i believe it was the burtoogle version. I agree that it draws strokes inside of the edge, not on it. But the standard Cura does trace the actual model edge and it shows that in the preview. I measure the cube away from the corners and bottom layers because of the effects you mentioned.

See pict. This makes printing engineering parts impractical. I don't know if any other slicer does this. Simplify 3D is too expensive for me, and the others I've looked at have a terrible user interface. Not at all polished like Cura. Cura is much better, but I'll have to adjust all of my models to account for this SOP. Simply scaling a model won't work, since only the outer-most features would be reduced by 0.4 mm, and others would be to a lesser extent.

3) "additional .4mm is my nozzle width" - okay so this is a common thing for people to worry about. If you slice a solid 25mm cube and your line width is 0.4mm, cura is smart - it knows that the lines of filament will stick outside the nozzle by 0.2mm all around so it shrinks all the walls inwards by .2mm which should result in 23.6mm of movement in the gcode and a 24mm cube. The people who wrote cura are pretty damn smart.

Maybe in the future there might be an "engineering mode" ? Slicing might take longer due to the extra calculations but I'd use it in a heart beat.

I have never been happier since this purchase. My best investment on my 1F machine. No issues setting up works like a dream. Thanks!

Thinnest wallreddit

When I check the "Print thin walls" option, it does fill in those gaps but instead of the nozzle tracing direct paths between the vertices, it scribbles several of the lines, where the gaps would otherwise be. (Screenshot (42).png and Screenshot (43).png)

Now if your cube is hollow it also steps inward (into the wall) for the inner walls. So if you have a hollow cube with 3mm thick walls, cura knows to attempt to print them thinner than that.

When making small text, I make the legs 0.5mm wide instead of 0.4mm, to avoid gaps when the STL might make the walls just a little bit thinner than 0.4mm in corners (and cause gaps), due to the triangles. But I am using an older Cura version, so I don't know how the newer versions handle this.

4) So what you see in the third diagram you show? That's fixed in the burtoogle version of cura. The official cura release doesn't do thin walls great. Burtoogle version has some nice fixes for thin walls.

gr5, Torgeir; Thanks for your comments and help. I have downloaded the Arachne Engine Beta and voila! It does print single walls on my part. Wow that is amazing. I have to adjust a few things but overall it does what I wanted it to do. I can now print models that has internal features as well as perfect thin walls.

An interesting note, when I change the surface mode to "Surface", it draws the lines perfectly, however, it creates an inner shell, doubling the overall thickness and the print time.

I did download and try the burtoogle version. It works great if the tube is square, but was no different on the hexagonal tube. Thanks. I might upload an stl, but to be honest, I decided I liked the double-thick wall that was produced. As it turns out, a 0.8mm thick hex tube that is 1/4" minus 0.4mm across flats is incredibly strong in PLA at 190°C.

But as gr5 said, it really draws its strokes inside of the model-edge, not centered on the edge. It takes its nozzle-width into account. Similar to image-editing programs where you can stroke a selection with settings: stroke inside edge / centered on edge / outside of edge. Here it is inside.

I have also attached two pictures showing the weight difference. Surely Cura part is much heavier than the Simplify3d one. Also the finish is much nicer on Simplify3d.

How to make awallthinner

The messy scribbles are...acceptable, but I'd really like a cleaner, faster print. I would just make a solid model and use the "vase" or "Surface" mode, but I really need those holes in the sides.

Right - you could set the line width to 0.39 or 0.35 - you can print down to about 0.35 without much (any?) noticable loss in quality. Or up to around 0.6 (but you may need to print slower).

I think the extra width that you measure might come from ringing- and thickening-effects around corners? When slowing down to take a corner, the nozzle inside pressure does not immediately drop, it lags, so the nozzle extrudes a bit too much compared to the now slower speed. This makes corners thicker. Analog for ringing, sine-wave mechanical oscillations around corners. This could easily explain 0.2mm extra width. Also blobs and overextrusion could explain that, if they would be present. Also, "elephant feet", the sagging of the first layers, could make a model seem wider than it is, if you measure it.

Now if your cube is hollow it also steps inward (into the wall) for the inner walls. So if you have a hollow cube with 3mm thick walls, cura knows to attempt to print them thinner than that.

The additional 0.4 mm is my nozzle width. So what Cura does, is it places the center of the line exactly at the wall perimeter of the geometry. So each exterior wall is going to be exactly 0.2 mm (or half the nozzle diameter) beyond the geometry of the model. So when it is, say, a tube, with 0.4 mm wall thickness, Cura is stumped. And when I put that on surface mode, it tries to trace both the outer wall and inner wall, thus drawing two walls instead of one.

I have recently bought Simplify 3D and I have to say it prints single walls without any issue. All I had to do set 'External Thin Wall Type' setting to 'Allow single extrusion walls' and the print came out amazing.

The choice between Air- or Water-cooling often depends on your setup preferences. We've ran 3d carves that have lasted many days with both and have found little difference in their performance. General advice is if you're wanting to regularly carve aluminum go with water-cooled. But if you're only hoping to do aluminum and mostly carve wood, the air-cooled is more than sufficient.

We own and have tested/documented a variety of CNC machine controllers and have found nearly every one is compatible, to some extent, with our Spindle Kits/Systems and ATC Systems. For these tested/documented controllers, we will do our best to help solve any problems that arise as they relate to our spindles. However with untested/undocumented CNC controllers, while it may be Spindle capable, the extent of that spindle support is likely not known to us. In those cases we can only provide limited guidance on how our VFD works. We are unable to provide full plug-n-play instructions for untested/undocumented CNC controllers. In these cases it is your responsibility to ensure compatibility and integrate the two systems together.

There is a good reason that cura has never been able to do this but I don't want to get into it unless you really want to know. Just trust me that it's a pretty good reason. But what you ask for has been asked by so many thousands (millions?) of people. And now I believe (I'm not certain) that Arachne can do this. Maybe.

gr5, thanks! Sorry I failed to respond to your suggestion. I'm told to stay home from work so, being with my family which I love, I'm way busier than normal. LOL. 6 home-school kids and an exhausted wife. I'm not ignoring you.

ER20 collets support up to 1/2" shank bits, but this feature comes at a cost. Only 80mm Spindles can support such a large collet. Typically this will require you to purchase an 80mm Spindle mount from your CNC manufacturer. Helpful video about how collets work: https://youtu.be/oLuf_A-K2v4

PwnCNC is a small company bringing innovative and unique products to the market. We don't have millions or even tens of thousands to order pallet loads of supplies at once. We've also poured our knowledge into the Spindle System with features not found anywhere else. The testing, integration and wiring work takes time. In addition, our VFD includes a 20-month warranty while our Spindle motor includes a 6-month warranty.

Short answer is no... but that doesn't matter with our Spindle Systems. Our VFD Enclosures have a very simple plug for use with an IoT power strip that provides the exact same functionality the BitRunner offers. You can plug your dust extraction right into the IoT power strip, the strip into our VFD and when RPM's go over 5500... your extractor will turn on.

Cause there is two walls, the slicer try the closest path and this is why the surface is uneven esp. at the top because the wall distance increase at this place.

I printed a 25 mm³ cube and found that my printer is spot on. But in the X and Y axis, that 25 mm prints at exactly 25.4 mm.

I'm wanting to print a hollow hexagonal tube in which the wall thickness in the model is 0.4 mm, the same as my nozzle. (Screenshot (40).png)

A "Spindle Kit" is simply a collection of these parts paired together with the proper VFD programming. Our Kits provide the most basic of spindle functionality at a reasonable price. Note that a VFD Enclosure Upgrade is required before you can upgrade to our ATC System.

We know that although the above listed options are most popular they are not perfect for everyone. Over the years we've been working with G-Penny, we've developed a very strong relationship which you can directly benefit from. Thus we've developed a great relationship with G-Penny and have access to their entire collection of motors. If you'd like a motor option that's not listed above, please reach out to us to request a special-order motor and we'll see if we/manufacturer can accommodate.

We own many brands and configurations of CNC machines to ensure our Systems are compatible. We program the VFD to match the control method your particular CNC machine uses.

By the way you *can* print 0.4mm walls with a 0.4mm nozzle using Cura if you choose print thin walls but it still does 2 passes.

By default we sell motors for wood-working purposes. These are typically 2-pole 400Hz motors that have a usable range between 8000-24000 RPMs. However we do offer other motors upon request. Purchased less frequently but still available are our 4-pole 800Hz motors that provide the higher torque at lower RPMs which is required for Metal-working. Learn about one customers experience here.

You probably want to download the burtoogle version - I suspect it will do a somewhat better job or burtoogle might have suggestions but he's probably asleep right now - maybe in a few more hours he can answer you.

This gets a bit technical so bare with us. In order for a 2.2kw motor to run efficiently at 110v, it requires 20amps of power. In the US we have three 110v circuit options in which the most common and in every home is the 110v at 15amps. In some rare cases folks will have 20amp plugs but a good rule of thumb with electricity is always make sure the circuit is rated for more than the device you're plugging into. Therefore a 2.2kw 110v 20amp motor would require the next step up which is 110v at 30amp.Our thought here is if you're going to pay an electrician to come out and install a 110v 30amp plug... it is far safer (lower amperage), more common, and even helps resale value of homes if you were to install a 220v 20amp plug instead. (Resale?? It is very common for woodworking that tools come in 220v. So for future owners of your home who want to put a shop where you did, it's more valuable to have a 220v circuit than a 110v 30amp circuit).Thus we only offer 1.5kw motors max for 110v which only requires 12amps and work perfectly with a dedicated 110v 15amp plug. For our 2.2kw 220v motors they only require 10amps to run efficiently. Due to all this electrical knowledge... we did identify the most valuable aspect of 2.2kw motors and that's the ER20 collets. So we worked closely with our Spindle motor manufacturer to provide a 1.5kw 80mm motor with an ER20 collet to achieve this.

A "Spindle System" is a fully engineered solution. We engineered the perfect Enclosure to wrap around our high quality VFD. This allows us to offer full plug-n-play functionality for all cables. Our Spindle Systems are directly upgradable to an ATC System.

PwnCNC makes products to help the average maker & DIY'er use their CNC machines more effectively. We have a true passion for this stuff.

PwnCNC's Spindle Systems are done right. They are packed with lots of features as well as high quality parts from manufacturers we truly believe in. We have definitely nailed it with this product and we're certain you'll agree.
