Michael,
That looks like a clone to this one Router11 CNC Kit which I actually had for a short time. The ER-11 was nice, but I ultimately ended up returning it for bearing noise which I suspected would ultimately lead to failure. OpenBuilds was very accommodating in the return.
I think that none of these routers are truly meant for use in a CNC. Makita does not certify any of their routers for use in a CNC machine. Those manufacturers that do are simply playing a numbers game, counting on a favorable ratio of sales/returns. But any trim router/wannabe spindle is not going to be up to the task of running for hours non-stop. But to many hobbyists just starting out, they are perfectly suitable for awhile.
This is why I’ll once again encourage Onefinity to develop a 43mm spindle holder for this line of spindles that are truly designed for long-term running. I personally don’t want the mess of hooking up a VFD spindle when one of the 43mm milling spindles are every bit as plug-n-play as a router.
