@BartDring Since you’ve used both now, Have you noticed anymore heat with the air cooled over the water cooled?
The air cooled one does get warm (not worrisome) to the touch where the water cooled one is not even noticeable. I am at our bi-weekly Beer and Making event right now and we just ran a bunch of jobs on it.
Thanks! Is your air cooled one 120V? I am having a hard time finding an air cooled that is not 220V, seems just the water cooled ones come in 120V.
@DavidLovely We only bought one VFD. It came with the water cooled one. You can sometimes buy them separately. I would contact the sellers. They might be able to create the right pair for you.
@BartDring I hope I am not bothering you too much! With the 0.8kW water cooled spindle, were you able to get the water lines and power cable (16/4) in the stock drag chain?
@DavidLovely. We did not put it in the drag chain. It did not look like it would fit. We probably swap spindles on that machine 6 times per week. It is our main test machine, so we take a few short cuts.
Can you upgrade to the 400W or 600W spindle when getting an X-Carve, or do you have to purchase them separately? Any time frame on offering the 110VDC power supply upgrade?
When I first built my Shapeoko2 the only spindle I had on hand was a 1.5kw water cooled 80mm dia. spindle. And since I was building it with a 1 meter wide gantry you can imagine there was measurable amount of twist on the gantry. I cured this by inserting a “T” shape extrusion I found that had a thickness that perfectly filled the void between the two maker slide extrusions that make up the gantry. When the assembly was drilled and bolted together, it gave me a gantry that was very strong and handled the weight of the big spindle with very little flex or sag.
I ran the Shapeoko like this for a few weeks until acquiring a Quiet Spindle. There was a slight difference in noise level with the new spindle, but the biggest change was a noticeable increase in “snappiness”. With the reduction in weight the X axis could really zip back and forth and the occasional lost step in the X axis disappeared completely.
The really nice discovery was that there was no loss in cutting ability. The much smaller 300w spindle handled all the cutters I was using with the larger 1.5kw spindle perfectly. I’ll note that I have only tried cutters up to 1/4" diameter and smaller. Bigger router cutters may perform differently, so, YMMV.
I started looking into some spindle upgrades and found a couple on AliExpress. I’m not too familiar with these, but they look like what everyone has been posting from Amazon.
HERE is one, its 220v and looks exactly like a couple I’ve see posted. This one comes with everything you need and is a pretty good price I think.
I’m going to keep searching the site for a 110v version, but I thought I’d get your guys input!
I just got my package from China. I ordered from ebay, one of the only 110V options out there.
Tonight, I put together a heavy duty power cord, and got the inverter to power up. The manual is both detailed and vague, Also, while the sticker on the inverter clearly says 110v, and it does power up, the list of models in the manual makes no mention of a 110v model.
Anyway, this setup did not include the cooling stuff, just a cast aluminum mount (I think I will probably end up using the 611 mount), and plug so you can build your own cable, (I ordered some shielded 300V 15Amp cable from mcmaster to use for this), the inverter, and the spindle. The cooling connectors were not the standard 3/8 size, but a 1/4 ID, 5/17 OD stuff. I got some of the thinner tubing, but I still need to reducers to fit it to my pump radiator setup.
Also missing is any docs on the spindle itself, like what are the safe ranges for input frequency.
In retrospect, it might have been a better idea to hire an electrician to install a 220V outlet in my shop rather than go with the 110V model, but we will see.
I just hope you can’t hear the whine from inverters. Drives me nuts.
It makes an awful whine. I was wondering if it was a bad fan, or just the normal noise of one of these things. It also smells like gun powder for some reason.
That is a standard 611 mount, but we had to wrap the spindle with a thin sheet of Styrene for it to fit.
Do you mean a solid styrene plastic, or a foam? Can you post a picture of how you have it shimmed? Thanks.
Interested in knowing more about the styrene too and where I can find a few inches… I heard some reports of the mount being tight on the 611 so hoping that helps a bit with the 65mm spindles.
i am not familar with that drive. I have experience with yaskawa drives and ABB drives. there may be a setting to change the operating frequency to reduce the whine. I believe the whine is actually a biproduct of the triacs switching. Hope this helps
If I may ask, where did you purchase the 800w air cooled spindle and VFD? Also, is it 110v or 220v? I would also like to upgrade my spindle and not mess with water cooling if possible.
We purchased from eBay. We are trying to sort through the the actual manufacturers to find a good quality source. I cannot give a source yet, but here are some guidelines
- Make sure the body diameter is 65mm
- Make sure the spindle voltage matches the VFD voltage.
- The VFDs with the pot knob are nice.
Here are some photos of our VFD.

Thanks for the quick response. If I am reading the sticker correctly, it is 110v input, and 110v output? So I could run this off a “household” outlet and the spindle runs off 110v as well?
The spindle is 3 phase 110 AC.
You should search the web for a PDF manual. It will give you all the details. It will also give you an idea of the complexity of these things.
You won’t be able to run 3 phase off of household current. Is there a phase converter built in?
