Hack for new Makita RT0702C router for remote control relay or SSR

The newest Makita RT0702C router features a anti-restart function that prohibits the router to start when the power is cycled. Sadly this makes it incompatible with users that use the remote control panel, or users that use their own relay / SSR setup to automatically start and stop the router when the g-code is running.

I’ve investigated the router and have good news, it’s a relative simple hack to make it compatible. I’ve written a complete guide on my website how to hack the RT0702C:


Hello ! I followed your tutorial to hack my Makita router, and everything goes well until I plug it. Then it blinks red, unless I unplug one of the black wires on the relay. Wich means that even if the relay is of, I have a contact between my two black wires. I tried with two différents relays and the result is the same… Have you an idea of what I did wrong ?
Thank you !
