Here is some info I received a while back from super PID:
I never got around to doing this to my 7518 or was it 7519?! I ended up
removing the soft start and using a harborfrieght speed control.
It works but way clunky & not reliable. Anyhoos......
Super-PID is universally compatible with all the routers available on
the market, once the router internal speed control and/or soft-start are
Attached are some photos showing the router modifications and some
examples for the RPM sensor setup.
Router mod for your PC 7518/7519 is very easy; remove the top cover,
slide out the PCB, and then solder join all 3-legs of the router triac
together with pre-soldered wire. Pre-solder the end of a 12 inch or so
length of wire solder to one triac leg, then the second triac leg, cut
to length. Then solder join the third triac leg and cut wire end to length.
Attached are some photos of the 7518, sorry no pics of 7519.
It appears the 7519 also has a module/circuit board with the triac.
See pdf attached. If you can access the three legs of the triac on the
circuit board solder them together. If the module is sealed or if you
want to remove the entire module, remove the module and also remove
the blue wire and then join the black wires together.
Hope this helps.
We are available anytime for questions or support with this mod. Best
of luck with it.
General instructions - router modification;
Routers WITHOUT a soft-start feature may have the option to set the
speed switch to full-speed, so then no router mod is required.
There are basically two methods to disable the router electronics (the
router internal speed control and the 'soft-start' feature);
(1) The easiest is to solder join all 3 legs of the router triac
together (see attached photos). If the router triac is accessible this
(2) The other method is when the router triac is enclosed within a
sealed module. In this case the module needs to be disconnected and/or
With the module (typically 3 wires go to the module) the basic procedure
A. Remove/cut the THIN wire to the module (powers the module electronics).
B. Join the two THICK wires together. These thick wires take motor power
into and out from the module, join together to eliminate the module.
C. Make sure all the wires are safely insulated as needed.
We are available for tech support with confirming the module wires etc.
If you are not sure about which wires, please send a photo showing your
router module and the wiring.
There is also a lot of information contained within the Super-PID thread
on the CNCZone Forum. A 'search' of the thread may be helpful; http://www.cnczone.com/forums/diy-cn...ontroller.html
The RPM sensor cable comes hard wired. However, our online order page
has jack plugs and sockets as an option for fast disconnect of the RPM
sensor; www.SuperPID.com - Super-PID Products and Accessories
