MPCNC DW-660 SuperPID RPM Sensor bracket

thingiverse

Building an MPCNC has been fun and challenging. I wanted a speed controlled spindle that was readily available and easy to implement. I decided to go with the Dewalt DW-660 and SuperPID speed controller. I also wanted my machine to look as non Frankenstein as possible. to that end I created this sensor holder to be mounted in the top of the router concealed internally. I removed the switch as it will be turned on and off with the SuperPID. If you want to leave the switch installed let me know and I can make the adjustments for that work. This is a snug fit and is held in place by the standoffs molded into the router housing. Edit: Added STL for keeping the switch intact as I decided to leave the switch installed. I also oriented the parts as I printed them, still no supports and a Brim of 10 wide. Also note that the switch delete version has half of the top missing. This is to ease installation. the switch version is a very tight fit by design and is installed into the housing half before installing the housing to the router. Install the sensor flush with the bottom of the bracket, then hot glue into place. also makes it easier if you plug the back spade connector (all brass one) on before the half is reinstalled onto the router. Then install the spade connector (pink) after the housing has been installed to the router. Edit: I have deleted the first two iterations of the sensor holder. After testing each by cutting an actual project and measuring spindle temps, I have landed on a final version that is working reliably and fits as near perfect as I am willing to make it. The fit is snug and is best printed with PETG for temperature resistance. with the final version the Spindle temp stayed low and has worked reliably for roughly 40 hours of cutting.
