I have a 3020 Pro Max V2. It’s a great little machine that comes with a 300W spindle motor, It’s an excellent upgrade from the 3018 ProVer V2 I started with that had a 75W spindle motor. Both of these machines are great entry level machines for CNCs and they have a very small footprint. The 3020 is especially sturdy and precise. They’re not the fastest machines though. Depth of cut and feed rate are limited by what the spindle can handle.
Enter the new 710W Spindle motor. This thing comes packed nicely and it feels very high quality. It comes with a long cord that detaches near the motor so it’s easier to manage. When paired with the appropriate bracket, it took me maybe 5 minutes to swap out the spindle motors. This one is much bigger and heavier than the stock spindle that comes on the 3020, but it still has virtually no give or wobble when mounted on the machine.
I’m not an expert at CNC machining so it’ll take some trial and error to get the feeds and speeds dialed in, but after just a few runs I can tell you that this will speed up production exponentially! I ramped up the speeds about 180% of what I typically ran with the original motor and I doubled the depth per pass. The spindle handled it without a sweat. I’ll increase the depth per pass a little more and finish projects even faster.
My tests were in .7” plywood and just used a 1/8” straight bit with straight cuts (no 3D carving). I had the spindle motor on its highest speed. I’m not sure when to use lower speed, but I assume it’ll be nice to have that option once I learn how to do some fine detail carves. For the shapes I carved in my test, it was still extremely accurate and precise, so I’m not concerned about any loss of performance in that aspect.
Some other pros:
This spindle comes equipped with a collet that accepts 1/8” shank bits so if you’re upgrading like I did you can use your same bits.
You can buy a separate collet to run 1/4” shank bits which really increases your options.
The blue spindle mount adds a nice pop of color to the machine.
The spindle has a large section where it can be mounted in the bracket. This makes it easy to slide up or down and accommodate different thickness of stock for your projects.
Cons:
The main drawback I’ve noticed is noise. Since this spins up to 10,000 rpms faster than the previous motor, it is significantly louder. I’ll take this tradeoff because its much louder but it only needs to run for a fraction of the time.
The power source of the motor is now separate from the CNC machine. You’ll need an additional outlet, and you must turn on the spindle manually vs. through the software. Once you get the cords plugged in at your station, this is hardly an inconvenience, at least for my workflow.
Final Thoughts:
This affordable upgrade drastically increases the ability of the smaller machines. It will literally cut production time in less than half and time is a very valuable resource. I have the blue trim routers from Genmitsu and they’ve been fantastic even after a lot of use. I haven’t seen any issues whatsoever. This machine seems quite similar to those trim routers so I’m pretty confident this will be very durable as well. Another great use for this product would be to install it in a router lift and use it at a router table. It is sleek and powerful and with a different collet it could easily run 1/4” shank router bits for edge profiles or flush trimming or even small grooves/dados.
I would highly recommend this upgrade to anyone who wants to speed up their production and unleash their CNC machines.
