All spindle kits expected to ship within 3-8 weeks of your order date.
* Spindle kits for Onefinity ELITE will take a bit longer to ship, however they will be delivered before your machine.  
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.  

Note: We believe in your abilities and our VFD's do not come locked.  This means you can explore settings and tweak them as your knowledge of the VFD manual matures.  We are also posting tons of information to our knowledgebase to ensure you're as informed as you want to be.

* Onefinity Elite series kits do not come with the Manual Override switch since the Masso controller handles all control operations perfectly.



Which cooling option should I choose?

The choice between Air- or Water-cooling often depends on the types of cuts you perform.  If you're doing short cuts from a few minutes up to an hour.. Air-cooled is a great choice.  If you're doing 3d carves that last for many hours we'd recommend getting a Water-cooled motor.

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.
