a description of how to modify the DW611 for remote power, light and speed control can be found here… SO3: How to mod the Dewalt DW611 for remote speed, light and power control
I want to remote mount the speed control pot for the router and I think I trashed the pot trying to desolder it. I tried measuring the resistance range from settings 1-6 but I get erratic readings. It looks like somewhere around 1 ohm max but I don’t trust that number at all. Does anyone know the resistance range for this potentiometer?
Some notes about the DW6111
It has what appears to be a hall sensor for speed control feedback. The upper end of the motor shaft has a disc that is right below the control card. If the control card isn’t over that disc then the motor will run max speed regardless of the speed setting. That means you have to remote mount a potentiometer and you can’t remote mount the entire control electronics. I assume this feedback means that this router ups the voltage if the router speed slows down. This is the reason I want to keep the OEM speed control. If I remote mount the pot I can put just make a label showing RPM settings and RPM’s should stay relatively close for most jobs. I don’t know how well the controller adjusts for heavy loads or how accurate it is. I’m pretty sure generic external router speed controls just PWM power which means you lose the closed loop speed control that you get with the OEM setup (not completely sure about that). So, I don’t want to use a generic router speed controller.
If you remove the top cover there are two small wires (red and black) that run down into the base of the router. Those wires are for the LED’s at the base. I tested the output of the card for those pins and it looks like its putting out 1.2 VAC but maybe it is some kind of PWM’d signal… I don’t know. The LED’s are pretty bright when run at 5-6 VDC. I will probably just run those wires to a DC power supply so I can turn them on and off from the front of my enclosure.
Hopefully that info helps someone. I think I’ll just try to find a pot in the 1 ohm range and see what happens. If you have any info or tips, feel free to pass them on.
