I purchased the 2.2kw 220v ER20 80mm Round Water cooled version from him last fall. I’ve been absolutely happy with it and would do it again. I also am a hobbyist, thus the very good reason for “plug-n-play”.
I ordered the optional Kool connectors, which are worth it in my opinion. I also ordered the optional case for the VFD, which doesn’t appear to be optional now.
Shortly after I received it and before even installing it I saw on his Facebook page that he just released an option on his case to connect with an IoT outlet strip. There’s another discussion of this on the forum. He didn’t even advertise an upgrade option but he added one quickly when I asked about it. It did require me sending the VFD back to him and I paid for the upgrade along with some new cables. It also required 2 weeks time. I don’t see this option on his current website, maybe it’s just included now. But you want it.
Because of this late option add-on, I did have an issue getting it to work the first time. but he and someone else on his support ticketing system were quick to address it and get it up and running.
The DB25 connector was all correctly wired. I did have to buy a short piece of thermostat wire from the local hardware store to go between the IoT connector he provided and the IoT outlet. But that was easy.
I did order and use the Vevor Chiller, which is mentioned elsewhere on this forum. He did not require it, but I’m glad I did. It has a temperature readout and an internal fan that kicks on when the temp gets to about 21 degrees celsius.
A few things I like most about it:
-
The Onefinity controller triggers it on and off when you start a toolpath. I do a lot of 3D carves and don’t always watch it so when it finishes now everything just shuts down.
-
I like having multiple size collets now, didn’t expect that. Sometimes when pocketing thick wood you want to get more detailed using an 1/8" bit. Since the cutting portion is not that deep you really need a 1/8" shank. It’s easy to change collets.

I don’t like to run long carves overnight. With this Spindle you can pause the OF controller, which leaves the spindle running. However, the PWN spindle case has a pause button on the front - the little, yellow P circle on the middle/bottom of the case. When I want to start it up again, I un-pause the Spindle first then unpause the OF controller.

Think I mentioned I don’t always watch my carves… that gets me in trouble sometimes. Once, the finishing pass started in an area that had not been roughed and it went too deep. Another time, my bit was too short to get to the bottom of the tool-path. In both cases the OF controller stopped and also the spindle had an error code, This is what I wanted. Yes, I ruined the wood but after rebooting everything work fine.
This is my first time with a spindle. Up until a couple years ago I knew very little about CNC machines. The spindle manual which comes with it is thick. There are a ton of settings. I didn’t have to change any of them, it was all ready for me. Reading about others, getting a setting wrong or the interface wrong with the OF controller gives you an opportunity to fry your new VFD. I’m sure I paid a little more, but for me it was worth it!
P.S. The small rectangular control panel at the top, center of the VFD does come out so you can use it as a remote. It does require a regular network cable (RJ-45 connectors) to do this with, not supplied. Since the OF controller starts and stops it automatically, I’ve never really had a need to use this remotely.
