MPCNC DW-660 SuperPID RPM Sensor bracket

thingiverse

Building an MPCNC has been a thrilling adventure, full of twists and turns. I was determined to have a speed-controlled spindle that would be easily accessible and simple to implement. The Dewalt DW-660 and SuperPID speed controller caught my eye, offering the perfect combination of performance and ease of use. To ensure my machine looked as sleek and modern as possible, I designed this sensor holder to be mounted discreetly in the top of the router. I removed the switch, opting instead to control it with the SuperPID, but feel free to let me know if you prefer to keep it installed - I can modify the design accordingly. This sensor holder fits snugly into place, secured by the standoffs molded directly into the router housing. Edit: After some deliberation, I've added an STL file for keeping the switch intact, as I decided to reinstate it. I also aligned the parts according to my print settings - no supports needed, and a 10-wide brim did the trick. Notably, the switch delete version has a portion of the top removed to simplify installation. The switch-intact version is a tight fit by design, requiring installation into the housing half before attaching it to the router. To secure the sensor, position it flush with the bottom of the bracket and hot glue it in place. It's also beneficial to connect the back spade connector (the brass one) before reinstalling the housing half onto the router, followed by connecting the pink spade connector after the housing is securely attached. Edit: I've since deleted the initial two iterations of the sensor holder, having thoroughly tested each version by cutting an actual project and measuring spindle temperatures. After refining my design through trial and error, I'm pleased to report that my final version is working reliably and fits with near-perfect accuracy. The snug fit makes PETG a recommended material for temperature resistance. In my testing, the Spindle temperature remained low, and the system performed reliably for approximately 40 hours of cutting.
