Notice:  We're short on a few supplies, please allow for a few extra weeks to process and ship out your spindle kit.

This is a "bundler" product... you must answer the questions on this product page and we'll add the different parts to your shopping cart related to your answers.
Notice:  We have TWO spindle kit queue's with different timings...
  1. Onefinity Elite Buyers:  Folks who order a spindle kit to go with their new Onefinity Elite machine... our ask is that you provide your Onefinity Elite order number.  We'll coordinate shipping with Onefinity directly so your new spindle kit ships ahead of your machine so you can get started right away.
  2. Everyone Else:  Orders for folks who already have their CNC machine, we are processing this queue faster and your kit will likely ship within 3-5 weeks.

We care about every single order and try our best to have high quality products that are prepared and shipped in a timely manor.  Our goal is to have your kit in hand as soon as possible no matter which queue you fall into.

PwnCNC's Spindle Kits are done right.  They are packed with lots of fully tested 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.

What makes PwnCNC's Spindle Kit different?

We've spent years gaining the expertise we're pouring into our spindle kits.  Every spindle kit is fully tested and includes the highest quality parts to make your experience as plug-n-play as is humanly possible.  All of our cables are properly shielded and drained to reduce electrical noise.  We add a very special EMI Power Inlet Filter to our VFD enclosure which ensures high voltage wiring is safely hidden.

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

Which cooling option should I choose?

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.  

Where's the 2.2kw 110v motor option?

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 voltage), 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.

How loud is a spindle compared to trim routers?  What about between cooling options?

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.

I have a Shapeoko with a BitRunner, can I continue to use it?

Short answer is no... but that doesn't matter with our spindle kits.  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.

Why does it cost so much?

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 kit 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.

Compared to purchasing parts off large online retailers, our spindle kits adds:

  • The most advanced VFD Enclosure on the market
  • EMI Filtering AC inlet
  • Simple IoT output port (replaces BitRunner)
  • All wiring shielded from interferance
  • Warranty and support
  • Testing and shipped to order

Should I choose ER11 or ER20... what's the difference?

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.  

What is the runout of our motors?

According to our motor manufacturer, runout of our spindles is 0.01mm (High accuracy).

Can I carve mild-steel?

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.

    Notices and Warnings:
    • Onefinity Black-Box controllers should be upgraded to firmware 1.3 or greater to receive the best experience.  It is possible to use our kit in automatic mode with firmware versions before 1.3 if you follow our Temporary Addendum
    • Shapeoko 5 Pro's Warthog controller has an extremely poor quality PWM signal. Plugging into their spindle port will result in incorrect RPM commands coming from the controller.  An ICSP header is available within the controller that provides a cleaner PWM signal.  We have designed a pigtail that is working great in our testing.  Reach out to us via support@pwncnc.com to learn more.

    So Far So Excellent

    Received and unboxed. very impressed in the care taken to ship these unit/s. I have installed and powered up Controller, and tested the Spindle. I am currently waiting on the 80mm Z-20 Heavy Duty Z Slider and X-50 Stiffy I ordered from Onefinity before Install the remainder of the PWNCNC system. All should be here next week. I am not new to the spindle use on the Onefinity but the previous unit I purchased ran for about 3 months and is now in the landfill. Had too much to do so I am back to using the Makita Router. Hoping to complete the install over the coming Holiday weekend. I will provide a full review when up and running, Good Luck with the new location. More to follow.

    Spindle Kit Review

    So far so good.
    Very impressed with build quality and ease of set up.
    Did have to update firmware on OneFinity Buildbotics controller but that was very easy. Looking forward to a lot of hours with this spindle.

    A great upgrade

    I have been really happy since I upgraded from a router to the spindle, so much quieter. Customer service has been great when I have needed to ask a question, they are right there to pass on any information that I needed.

    Awesome upgrade

    Bought the elite and figured it was a good time to go ahead and get a spindle as well. Couldn’t be more pleased with it. Literally plug and play with a 1 min programming part on masso. Went with air cooled 2.2kw and it’s unbelievably quiet and smooth as glass. If you’re on the fence about a spindle choose PWN and you will not be disappointed.
